Changelog {#changelog}
=========
For fully detailed change log, please see the source repository directly. This
is just a high-level summary.
### libopenmpt 0.5.18 (2022-04-24)
* Pitch / Pan Separation and Random Variation instrument properties were not
resetting properly when seeking, potentially causing instruments to be
played e.g. at a vastly different pan position compared to playing the
module continuously.
* MED: Stereo samples were not imported correctly.
* zlib: Update to v1.2.12 (2022-03-27).
### libopenmpt 0.5.17 (2022-03-13)
* [**Sec**] Possible out-of-bounds write in malformed IT / XM / MPTM files
using the internal LFO plugin. (r17081)
* [**Sec**] Possible out-of-bounds read when using Amiga BLEP interpolation
with extremely high-pitched notes. (r17082)
* MO3: Pattern indices 254 / 255 were not treated as playable patterns even if
the original file was a MOD / XM.
* Correctly apply ST3-style effect memory when seeking in S3M files.
* Command S (S3M / IT style) effect memory was not applied when seeking.
* FLAC: Update to v1.3.4 (2022-02-21).
* pugixml: Update to v1.12.1 (2022-02-16).
### libopenmpt 0.5.16 (2022-01-30)
* [**Bug**] Possible hang with malformed DMF, DSM, MED and OKT files
containing 65536 or more patterns when destroying the module.
* [**Bug**] Avoid NaNs and infinite values with custom tunings.
* The letter "z" is now evaluated in fixed MIDI macros (Z80...ZFF) the same
way as in Impulse Tracker.
* MOD: Loosened VBlank timing heuristics so that "frame of mind" by Dascon
plays correctly.
* MOD: Validate the contents of "hidden" patterns beyond the end of the order
list when the file size matches the expected size when only taken "official"
patterns into account. This fixes Shofixti Ditty.mod from Star Control 2
while keeping other (partly broken) modules working.
* MED: Command 20 (reverse sample) is now only applied when it's next to a
note.
### libopenmpt 0.5.15 (2021-12-23)
* [**Sec**] Possible out-of-bounds read of stack-allocated array in malformed
AMS files. (r16243)
* [**Bug**] Fixed various undefined behaviour found with ubsan.
* IT: Even after libopenmpt 0.5.14 the filter reset logic was still not 100%
identical to Impulse Tracker: A note triggered on tick 0 of a row with a
Pattern Delay effect still caused the filter to be reset on repetitions of
that row even though the note wasn't retriggered.
* MOD: Loosened VBlank timing heuristics so that the original copy of
Guitar Slinger from Dizzy Tunes II plays correctly.
* mpg123: Update to v1.29.3 (2021-12-11).
### libopenmpt 0.5.14 (2021-12-05)
* [**Sec**] Possible out-of-bounds read in Chorus plugin with NaN plugin
parameters. Most implementations of the "fast math" compiler optimizations
will prevent this crash but it is not guaranteed. (r16096)
* [**Bug**] Fixed undefined behaviour with custom tunings found with ubsan.
* OPL: Improved channel allocation strategy when there are lots of faded-out
notes.
* MOD: Digital Tracker MODs have four unknown bytes right after the magic
bytes which seem to be ignored even by Digital Tracker itself. Just skip
over them.
* The logic when to turn off the resonant filter was broken in some edge cases
since libopenmpt 0.5.1.
* IMF: Implemented XE1-XE3 commands, which disable individual envelopes.
Command Nxy (cutoff slide + resonance) is now also partially supported
(only resonance for now).
* IMF: Filter envelopes were upside down.
* MTM: Omitting pattern loading through the load.skip_patterns ctl caused
sample data to be corrupted.
* S3M: Ignore O00 commands in files created with Scream Tracker 3.00 and 3.01,
as this command only gained effect memory in version 3.03.
* STM: Use S3M-like sample swap behaviour.
* XM: Disable arpeggio quirk for XMs made with Skale Tracker.
Fixes KAPTENFL.XM.
* miniz: Update to v2.2.0 (2021-06-27).
* minimp3: Update to commit 50d2aaf360a53653b718fead8e258d654c3a7e41
(2021-11-27).
### libopenmpt 0.5.13 (2021-11-14)
* [**Bug**] Fixed various undefined behaviour found with ubsan.
* IMF: Change envelope interpretation to be more like in XM instead of IT and
tighten header validation.
* MED: Some samples had a ping-pong loop when there should be no loop at all.
* MT2: Ignore incorrect drums chunk size in early MT2 files
(fixes e.g. "A little Rock" by Csumi).
* MT2: Work around initial master volume of 0 used in some files that apply a
fade-in a the song start using track automation that would stay silent
forever otherwise (track automation is currently not supported).
* OKT: Apply portamento on every tick.
* mpg123: Update to v1.29.2 (2021-10-23).
### libopenmpt 0.5.12 (2021-10-04)
* [**Sec**] Possible crash when loading malformed MDL files. (r15603)
* [**Bug**] Fixed various undefined behaviour found with ubsan.
* Seeking with sample sync sometimes didn't compute the correct sample
position with pingpong-looped samples.
* IT: Tremor command I11 erroneously behaved like I00 (use previous parameter)
unless IT Old Effects were enabled.
* PTM: Panning was translated wrong in some edge cases.
* IMF / PTM: Note Slide commands were sometimes slightly off.
* OKT: Better support for fine note slides.
* DBM: Echo enable effect parameter range checks were incorrect.
* XM: Sample texts in XMs made with MadTracker are now also decoded using
Windows-1252 encoding.
* in_openmpt: Song metadata is no longer reverted when viewing file info.
* mpg123: Update to v1.29.0 (2021-09-06).
### libopenmpt 0.5.11 (2021-08-22)
* [**Sec**] Possible crash with malformed modules when trying to access
non-existent plugin slots FX251-FX255. (r15479, r15518)
* [**Sec**] Possible read beyond sample start after swapping to a sample with
loop points set but not loop enabled. (r15499)
* [**Sec**] Fixed various possible crashes with malformed MMCMP files.
(r15504, 15528)
* [**Sec**] MED: Possible read past end of sequence name (stack-allocated, so
relatively unlikely to result in a crash). (r15477)
* Fixed excessive memory usage with files claiming to have an extremely high
rows per beat count while also using tempo swing. Maximum rows per beat are
now limited to 65536.
* STP: Avoid creating thousands of patterns when loading malformed files even
though no more pattern data can be read.
* mpg123: Update to v1.28.2 (2021-07-12).
* stb_vorbis: Update v1.22 commit 5a0bb8b1c1b1ca3f4e2485f4114c1c8ea021b781
(2021-07-12).
### libopenmpt 0.5.10 (2021-07-04)
* S3M: Honor the Stereo flag not being set. This improves the sound of some
tunes like Turbulence by Purple Motion.
* S3M: Detect MPT 1.0 alpha versions which didn't set the Stereo flag. In this
case, the unset Stereo flag is also ignored because MPT 1.0 alpha used the
default S3M channel panning anyway.
* S3M: Only for OPL instruments the high sample rate bits should be ignored;
for PCM instruments they are clamped to 65535 Hz.
* MOD: Do not apply ProTracker loop length quirk to MODs that could have been
made with Scream Tracker (fixes Soul-O-Matic by Purple Motion).
* AMF (DSMI): Format revisions 1 and 9, as well as early (technically
malformed) revision 10 files, are now supported. Surround panning commands
and instrument number without note are now converted correctly.
* AMF (DSMI): Patterns and samples were not read correctly in some files
(e.g. AVOID.AMF).
* GDM: Correctly import extra-fine portamentos.
* mpg123: Update to v1.28.0 (2021-06-05).
* ogg: Update to v1.3.5 (2021-06-04).
* stb_vorbis: Update v1.21 commit 8e51be04dc7dcee462e1f09e410faceab52cc6d2
(2021-07-02).
### libopenmpt 0.5.9 (2021-05-16)
* `Makefile` `CONFIG=emscripten` does not pass linker options to the compiler
any more, which caused latest Emscripten to issue warnings.
* The retrigger effect didn't work correctly for OPL instruments in some cases
depending on the chosen output sample rate.
* S3M: Emulate IT short sample retrigger quirk in S3M files saved with
Impulse Tracker and Schism Tracker.
* ProTracker 3.6 doesn't support sample swapping. It is now disabled when
loading a ProTracker 3.6 IFF module.
* Some files with "hidden" garbage patterns were not played correctly since
libopenmpt 0.5.3.
* MOD: E9x retrigger now works the same way as in ProTracker 2.
* MDL: Improve auto-vibrato accuracy.
* 669: Reject files that contain any pattern tempo higher than 15.
* Reduce memory consumption of malformed XPK-compressed files.
* mpg123: Update to v1.27.2 (2021-05-08).
### libopenmpt 0.5.8 (2021-04-11)
* [**Sec**] Possible null-pointer dereference read caused by a sequence of
`openmpt::module::read`, `openmpt::module::set_position_order_row` pointing
to an invalid pattern, and another `openmpt::module::read` call. To trigger
the crash, pattern 0 must not exist in the file and the tick speed before
the position jump must be lower than the initial speed of the module.
(r14530)
* [**Bug**] `libopenmpt.pc` did not list required system libraries `ole32.lib`
and `rpcrt4.lib` on Windows in `Libs.Private` field for static builds.
* [**Bug**] libopenmpt 0.5.7 broke seeking in some subsongs.
* The built-in LFO plugin did not load the correct initial LFO frequency.
* IT command S7x (instrument control) is now supported when seeking with
sample sync enabled.
* libopenmpt_ext `play_note` was cutting of channels even when there were
plenty of free channels to use.
* mpg123: Update to v1.26.5 (2021-03-22).
### libopenmpt 0.5.7 (2021-03-20)
* [**Sec**] Possible null-pointer dereference read caused by a sequence of
`openmpt::module::read`, `openmpt::module::set_position_seconds` with a
position past the song end, and another `openmpt::module::read` call.
(r14363)
* IT: Instrument / sample panning was reset on note-off / fade commands.
* IMF: Set Finetune is now implemented correctly.
* Fixed excessive memory consumption with malformed files in various formats.
### libopenmpt 0.5.6 (2021-03-14)
* AMS: Avoid allocating excessive amount of memory for compressed song message
in malformed files.
* S3M: Some samples or OPL patches were imported with a too high sample rate
if module was saved with Scream Tracker 3.
* vorbis: Update to v1.3.7 (2020-07-04).
### libopenmpt 0.5.5 (2021-01-31)
* [**New**] `Makefile` `CONFIG=emscripten` now supports
`EMSCRIPTEN_TARGET=audioworkletprocessor` which builds an ES6 module in
a single file with reduced dependencies suitable to be used in an
AudioWorkletProcessor.
* [**Bug**] stb_vorbis: Fix decoding of Vorbis streams without comments which
affected most Vorbis samples since stb_vorbis v1.20.
* `openmpt::ext::interactive::set_pitch_factor` wasn't applied to OPL voices.
* OPL channel state (in particular current patch) is now updated when seeking.
* The FT2 tremolo quirk is now also applied to MOD files. FT2 just copied the
quirky code from ProTracker!
* DMF: Preserve effects better in some situations where there is more than one
effect in a pattern cell.
* DMF: Improve import of finetune effect with parameters larger than +/-15.
* mpg123: Update to v1.26.4 (2020-12-24).
* pugixml: Update to v1.11.4 (2020-12-22).
### libopenmpt 0.5.4 (2020-11-29)
* AMS: An upper bound for uncompressed sample size is now established to
avoid memory exhaustion from malformed files.
* DMF: Support early format beta versions (in particular versions 1-4).
* MED: Also use octave wrapping in 8-channel mode for MMD0/MMD1 modules.
* MED: If 8-channel mode is activated, ignore BPM mode.
* MED: Emulate tempo commands F01 and F02 quirk.
* MED: Tempo commands below 32 BPM were interpreted as tempo slides.
* IMF: Instrument sample mapping was off by one octave, notable in the guitar
part of Astaris by Karsten Koch.
* pugixml: Update to v1.11 (2020-11-26).
### libopenmpt 0.5.3 (2020-10-25)
* [**Sec**] Possible hang if a MED file claimed to contain 256 songs. (r13704)
* [**Bug**] libopenmpt: `openmpt::is_extension_supported2()` exported symbol
was missing (C++).
* [**Bug**] `openmpt::module::set_position_seconds` sometimes behaved as if
the song end was reached when seeking into a pattern loop and in some other
corner cases.
* Increase threshold for ignoring panning commands from 820 to 830.
* Subsong names now fall back to the first pattern's name if empty.
* MO3: Avoid certain ModPlug hacks from being fixed up twice, which could lead
to e.g. very narrow pan swing range for old OpenMPT IT files saved with a
recent MO3 encoder version.
* MO3: Some files with corrupted envelope data could be rejected completely
(normally libopenmpt should fix up the envelope data).
* MO3: Song metadata didn't correctly identify MPTM as source format (it
appeared as IT instead).
* STM: Change tempo computation to behave like Scream Tracker 2.3 instead of
Scream Tracker 2.2, as the playback frequencies we use for sample playback
are closer to those of Scream Tracker 2.3.
* PLM: Percentage offset (Mxx) was slightly off.
* WOW: Fix loading of several files and harden WOW detection.
### libopenmpt 0.5.2 (2020-08-30)
* [**Change**] `Makefile` `CONFIG=emscripten` now supports
`EMSCRIPTEN_TARGET=all` which provides WebAssembly as well as fallback to
JavaScript in a single build.
* [**Regression**] `Makefile` `CONFIG=emscripten` does not support
`EMSCRIPTEN_TARGET=asmjs` or `EMSCRIPTEN_TARGET=asmjs128m` any more because
support has been removed from current Emscripten versions.
* [**Regression**] Support for Emscripten versions older than 1.39.7 has been
removed.
* PP20: The first few bytes of some files were not decompressed properly,
making some files unplayable (depending on the original format).
### libopenmpt 0.5.1 (2020-07-26)
* [**Bug**] `libopenmpt/libopenmpt.h` failed to compile with
`LIBOPENMPT_NO_DEPRECATE` defined.
* MPTM: Qxy now retriggers OPL notes if new compatibility flag is set in file.
* MPTM: Bring back old OPL note end-of-envelope behaviour for files made with
OpenMPT 1.28.
* IT: Global volume slides with both nibbles set preferred the "slide up"
nibble over the "slide down" nibble in old OpenMPT versions, unlike other
slides. Such old files are now imported correctly again.
* IT: Fixed an edge case where, if the filter hit full cutoff / no resonance
on the first tick of a row where a new delayed note would be triggered, the
filter would be disabled even though it should stay active. Fixes trace.it
by maddie.
* OXM: Some sample loops were not imported correctly.
* XM: Out-of-range arpeggio clamping behaviour broke in OpenMPT 1.23.05.00.
The arpeggios in Binary World by Dakota now play correctly again.
* S3M: Support old-style sample pre-amp value in very early S3M files.
* S3M: Only force-enable fast slides for files ST 3.00. Previously, any S3M
file made with an ST3 version older than 3.20 enabled them.
* S3M: Only apply volume and middle-C speed on instrument change if the new
sample slot has sample data.
* MOD: Fix an infinite loop in GamerMan by MrGamer by playing non-ProTracker
MODs more like FT2 would.
* M15: Improve tracker detection heuristics to never assume SoundTracker 2.0
if there is a huge number of Dxx commands, as that is a definite hint that
they should be treated as volume slides. Fixes Monty On The Run by
Master Blaster.
* MO3: Support OPL patches in MO3 files created from MPTM and S3M.
* DBM: If a global pattern command would be lost because both effect commands
in a cell would have to go into the regular effect column (e.g. a speed and
a tempo command), the lost command is now attempted to be written into a
different cell on the same row. Fixes "Party-Question V" by grogon.
* mpg123: Update to v1.26.3 (2020-07-16).
* stb_vorbis: Update v1.20 commit b42009b3b9d4ca35bc703f5310eedc74f584be58
(2020-07-13).
### libopenmpt 0.5.0 (2020-05-24)
* [**New**] OggMod compressed FastTracker 2 XM (OXM) modules are now
supported.
* [**New**] The emulated Amiga type when Amiga resampler emulation is enabled
can now be selected via ctl `render.resampler.emulate_amiga_type`. Possible
values are: `"auto"`, `"a500"`, `"a1200"`, and an experimental option
`"unfiltered"`.
* [**New**] libopenmpt: New API `openmpt::module::get_current_estimated_bpm()`
(C++), and `openmpt_module_get_current_estimated_bpm()` (C) which provides
accurate beats per minute information for module formats with time signature
and an educated guess based on speed and tempo for others.
* [**New**] libopenmpt: New type-aware ctl APIs that do not require memory
allocations and are thus realtime-safe:
`openmpt::module::ctl_get_boolean()`, `openmpt::module::ctl_get_integer()`,
`openmpt::module::ctl_get_floatingpoint()`,
`openmpt::module::ctl_get_text()`, `openmpt::module::ctl_set_boolean()`,
`openmpt::module::ctl_set_integer()`,
`openmpt::module::ctl_set_floatingpoint()` (C++), and
`openmpt_module_ctl_get_boolean()`, `openmpt_module_ctl_get_integer()`,
`openmpt_module_ctl_get_floatingpoint()`, `openmpt_module_ctl_get_text()`,
`openmpt_module_ctl_set_boolean()`, `openmpt_module_ctl_set_integer()`,
`openmpt_module_ctl_set_floatingpoint()` (C).
* [**New**] libopenmpt C++ New API `openmpt::is_extension_supported2()` which
takes a `std::string_view` parameter instead of `std::string`.
* [**New**] libopenmpt C++: New API
`openmpt::module::module(std::vector<std::byte> data)`,
`openmpt::module::module(const std::byte * data, std::size_t size)`,
`openmpt::module::module(const std::byte * beg, const std::byte * end)`.
* [**New**] libopenmpt C++: New API
`openmpt::probe_file_header(flags, const std::byte * data, std::size_t size, filesize)`,
`openmpt::probe_file_header(flags, const std::byte * data, std::size_t size)`.
* [**New**] libopenmpt_ext C++: New API
`openmpt::module_ext::module_ext(std::vector<std::byte> data)`,
`openmpt::module_ext::module_ext(const std::byte * data, std::size_t size)`,
`openmpt::module_ext::module_ext(std::vector<std::uint8_t> data)`,
`openmpt::module_ext::module_ext(const std::uint8_t * data, std::size_t size)`.
* [**Change**] std::istream based file I/O has been speed up.
* [**Change**] Dependency on iconv on Linux has been removed.
* [**Regression**] libmodplug: The libmodplug emulation layer has been removed
from the libopenmpt tree. Please use the separate `libopenmpt-modplug`
package instead.
* [**Regression**] foo_openmpt: foo_openmpt is discontinued. Please use
Kode54's fork foo_openmpt54:
<https://www.foobar2000.org/components/view/foo_openmpt54>.
* [**Regression**] Support for building with C++11 or C++14 has been removed.
C++17 is now required to build libopenmpt.
* [**Regression**] Support for client code using C++11 or C++ 14 has been
removed. C++17 is now required to build libopenmpt client applications.
* [**Regression**] Support for Visual Studio 2015 has been removed.
* [**Regression**] Support for GCC 4.8, 4.9, 5, 6 has been removed.
* [**Regression**] Support for Clang 3.6, 3.7, 3.8, 3.9, 4 has been removed.
* [**Regression**] Support for Emscripten versions older than 1.39.1 has been
removed.
* [**Regression**] Building with Android NDK older than NDK r18b is not
supported any more.
* [**Regression**] openmpt123: Support for SDL1 (but not SDL2) output has been
removed.
* [**Regression**] openmpt123: Support for SDL2 older than 2.0.4 has been
removed.
* [**Regression**] Windows XP and Windows Vista are no longer supported.
* [**Regression**] It is no longer possible to optionally use iconv for
character set conversions.
* [**Bug**] openmpt123: openmpt123 now honors the current locale and outputs
text appropriately.
* [**Bug**] openmpt123: Piping text output to other than console window
targets on Windows has been fixed.
* Greatly improved MED import. Synthesized instruments are still not supported
but support was added for: Multisampled instruments, delta samples, more
pattern commands, Hold and Decay, multiple songs and many other small
changes.
* Improved OPL channel allocation when more than 18 notes are active, so that
channels that have completely faded out are prioritized over channels that
have already been released but have not faded out yet.
* Interactively triggering an OPL instrument could cause the first pattern
channel to no longer be played back correctly.
* Fix some inaccuracies in OPL emulator.
* Fix overflow of OPL amplification happening at a synth volume level of 510.
* End-of-sample pop reduction of surround channels was applied to front
channels instead, causing a pop on the front channels instead of removing it
on the back channels.
* IT: Disable retrigger with short notes quirk for modules saved with
Chibi Tracker, as it does not implement that quirk.
* IT: Instrument and sample panning should not override channel panning for
following notes.
* IT: SBx is now prioritized over Bxx commands that are to the left of it.
* IT: Duplicate Check Type "Sample" should only be applied if the instruments
match, too.
* IT: Duplicate Check Type "Note" should compare pattern notes, but it was
comparing the new pattern note against the old translated note.
* IT: Various fixes for envelope resetting.
* IT / S3M: When combining SBx and EEx effects, don't skip the first row of
the loop like in FastTracker 2.
* S3M: Empty pattern commands now affect effect memory as well.
* S3M: Offset beyond loop end wraps around to loop start like in
Scream Tracker 3 + GUS (previously it just keep playing from the loop start,
which is neither what GUS nor Sound Blaster drivers do).
* S3M: Notes cannot be retriggered after they have been cut.
* S3M: Fix portamento after note cut (fixes antediluvian_song.s3m).
* S3M / MOD: Previous note offset is no longer used for retriggered notes if
there was no instrument number next to the Qxy effect.
* MOD: Sample swapping now also works if the sample that is being swapped from
does not loop. Swapping to a non-looped sample now stops playback once the
swapped-from sample reaches its (loop) end.
* MOD: Fix early song ending due to ProTracker pattern jump quirk
(EEx + Dxx on same row) if infinite looping is disabled.
Fixes Haunted Tracks.mod by Triace.
* MOD: Previous note offset is no longer used for retriggered notes if there
was no instrument number next to the E9x effect.
* MOD: Vibrato type "ramp down" was upside down.
* XM: If a file contains patterns longer than 1024 rows, they are now clamped
to 1024 rows instead of 64 rows.
* XM: Do not reset note-off status on portamento if there is no instrument
number.
* mpg123: v1.26rc3.
* ogg: v1.3.4.
* vorbis: v1.3.6.
* zlib: v1.2.11.
* minimp3: commit 55da78cbeea5fb6757f8df672567714e1e8ca3e9 (2020-03-04).
* stb_vorbis: v1.19 commit 37b9b20fdec06c75a0493e0bb59e2d0f288bfb51
(2020-02-05).
* miniz: v2.1.0.
* FLAC: v1.3.3.
* PortAudio: commit 799a6834a58592eadc5712cba73b35956dc51579 (2020-03-26).
### libopenmpt 0.4.0 (2018-12-23)
* [**New**] libopenmpt now includes emulation of the OPL chip and thus plays
OPL instruments in S3M, C67 and MPTM files. OPL chip emulation volume can be
changed with the new ctl `render.opl.volume_factor`.
* [**New**] libopenmpt now supports CDFM / Composer 670 module files.
* [**New**] Autotools `configure` and plain `Makefile` now honor the variable
`CXXSTDLIB_PCLIBSPRIVATE` which serves the sole purpose of listing the
standard library (or libraries) required for static linking. The contents of
this variable will be put in `libopenmpt.pc` `Libs.private` and used for
nothing else. See \ref libopenmpt_c_staticlinking .
* [**New**] foo_openmpt: foo_openmpt now also works on Windows XP.
* [**New**] libopenmpt Emscripten builds now ship with MP3 support by
default, based on minimp3 by Lion (github.com/lieff).
* [**New**] libopenmpt: New ctl `play.at_end` can be used to change what
happens when the song end is reached:
* "fadeout": Fades the module out for a short while. Subsequent reads
after the fadeout will return 0 rendered frames. This is the default and
identical to the behaviour in previous libopenmpt versions.
* "continue": Returns 0 rendered frames when the song end is reached.
Subsequent reads will continue playing from the song start or loop
start. This can be used for custom loop logic, such as loop
auto-detection and longer fadeouts.
* "stop": Returns 0 rendered frames when the song end is reached.
Subsequent reads will return 0 rendered frames.
* [**New**] Add new metadata fields `"originaltype"` and `"originaltype_long"`
which allow more clearly reflecting what is going on with converted formats
like MO3 and GDM.
* [**New**] `Makefile` `CONFIG=emscripten` now can generate WebAssembly via
the additional option `EMSCRIPTEN_TARGET=wasm`.
* [**New**] Compiling for DOS is now experimentally supported via DJGPP GCC
7.2 or later.
* [**Change**] minimp3: Instead of the LGPL-2.1-licensed minimp3 by KeyJ,
libopenmpt now uses the CC0-1.0-licensed minimp3 by Lion (github.com/lieff)
as a fallback if libmpg123 is unavailable. The `USE_MINIMP3` `Makefile`
option is gone and minimp3 will be used automatically in the `Makefile`
build system if libmpg123 is not available.
* [**Change**] openmpt123: openmpt123 now rejects `--output-type` in `--ui`
and `--batch` modes and also rejects `--output` in `--render` mode. These
combinations of options really made no sense and were rather confusing.
* [**Change**] Android NDK build system now uses libc++ (`c++_shared`) instead
of GNU libstdc++ (`gnustl_shared`), as recommended by Android NDK r16b.
* [**Change**] xmp-openmpt: `openmpt-mpg123.dll` is no longer optional and
must be placed into the same directory as `xmp-openmpt.dll`.
* [**Change**] in_openmpt: `openmpt-mpg123.dll` is no longer optional and must
be placed either into the directory of the player itself or into the same
directory as `in_openmpt.dll`. This is dependent on how the player loads its
plugins. For WinAMP 5, `openmpt-mpg123.dll` needs to be in the directory
which contains `winamp.exe`. `in_openmpt.dll` needs to be in the `Plugins`
directory.
* [**Change**] foo_openmpt: foo_openmpt is now packaged as a fb2k-component
package for easier installation.
* [**Change**] When building libopenmpt with MinGW-w64, it is now recommended
to use the posix thread model (as opposed to the win32 threading model),
because the former does support std::mutex while the latter does not. When
building with win32 threading model with the Autotools build system, it is
recommended to provide the `mingw-std-threads` package. Building libopenmpt
with MinGW-w64 without any `std::thread`/`std::mutex` support is deprecated
and support for such configurations will be removed in libopenmpt 0.5.
* [**Change**] `Makefile` `CONFIG=emscripten` now has 4 `EMSCRIPTEN_TARGET=`
settings: `wasm` generates WebAssembly, `asmjs128m` generates asm.js with a
fixed size 128MB heap, `asmjs` generates asm.js with a fixed default size
heap (as of Emscripten 1.38.11, this amounts to 16MB), `js` generates
JavaScript with dynamic heap growth and with compatibility for older VMs.
* [**Change**] libmodplug: Update public headers to libmodplug 0.8.8.5. This
adds support for kind-of automatic MODPLUG_EXPORT decoration on Windows.
* [**Regression**] Support for Clang 3.4, 3.5 has been removed.
* [**Regression**] Building with Android NDK older than NDK r16b is not
supported any more.
* [**Regression**] Support for Emscripten versions older than 1.38.5 has been
removed.
* [**Regression**] Support for libmpg123 older than 1.14.0 has been removed.
* [**Regression**] Using MediaFoundation to decode MP3 samples is no longer
supported. Use libmpg123 or minimp3 instead.
* [**Regression**] libmodplug: Support for emulating libmodplug 0.8.7 API/ABI
has been removed.
* [**Bug**] xmp-openmpt: Sample rate and number of output channels were not
applied correctly when using per-file settings.
* [**Bug**] Internal mixer state was not initialized properly when initially
rendering in 44100kHz stereo format.
* [**Bug**] openmpt123: Prevent libsdl2 and libsdl from being enabled at the
same time because they conflict with each other.
* [**Bug**] libmodplug: Setting `SNDMIX_NORESAMPLING` in the C++ API always
resulted in linear interpolation instead of nearest neighbour
* IT: In Compatible Gxx mode, allow sample changes next to a tone portamento
effect if a previous sample has already stopped playing.
* IT: Fix broken volume envelopes with negative values as found in breakdwn.it
by Elysis.
* MOD: Slides and delayed notes are executed on every repetition of a row with
row delay (fixes "ode to protracker").
* XM: If the sustain point of the panning envelope is reached before key-off,
it is never released.
* XM: Do not default recall volume / panning for delayed instrument-less notes
* XM :E60 loop bug was not considered in song length calucation.
* S3M: Notes without instrument number use previous note's sample offset.
* Tighten M15 and MOD file rejection heuristics.
* J2B: Ignore frequency limits from file header. Fixes Medivo.j2b, broken
since libopenmpt-0.2.6401-beta17.
* STM: More accurate tempo calculation.
* STM: Better support for early format revisions (no such files have been
found in the wild, though).
* STM: Last character of sample name was missing.
* SFX: Work around bad conversions of the "Operation Stealth" soundtrack by
turning pattern breaks into note stops.
* IMF: Filter cutoff was upside down and the cutoff range was too small.
* ParamEq plugin center frequency was not limited correctly.
* Keep track of active SFx macro during seeking.
* The "note cut" duplicate note action did not volume-ramp the previously
playing sample.
* A song starting with non-existing patterns could not be played.
* DSM: Support restart position and 16-bit samples.
* DTM: Import global volume.
* MOD: Support notes in octave 2, like in FastTracker 2 (fixes DOPE.MOD).
* Do not apply Amiga playback heuristics to MOD files that have clearly been
written with a PC tracker.
* MPTM: More logical release node behaviour.
* Subsong search is now less thorough. It could previously find many subsongs
that are technically correct (unplayed rows at the beginning of patterns
that have been jumped over due to pattern breaks), but so far no real-world
module that would require such a thorough subsong detection was found. The
old mechanism caused way more false positives than intended with real-world
modules, though.
* Restrict the unpacked size of compressed DMF, IT, MDL and MO3 samples to
avoid huge allocations with malformed small files.
### libopenmpt 0.3 (2017-09-27)
* [**New**] New error handling functionality in the C API, which in particular
allows distinguishing potentially transient out-of-memory errors from parse
errors during module loading.
* [**New**] New API `openmpt::module::get_selected_subsong()` (C++) and
`openmpt_module_get_selected_subsong()` (C).
* [**New**] Faster file header probing API `openmpt::probe_file_header()` and
`openmpt::probe_file_header_get_recommended_size` (C++), and
`openmpt_probe_file_header()`,
`openmpt_probe_file_header_without_filesize()`,
`openmpt_probe_file_header_from_stream()` and
`openmpt_probe_file_header_get_recommended_size()` (C).
* [**New**] New API `openmpt::could_open_probability()` (C++) and
`openmpt_could_open_probability()` (C). This fixes a spelling error in the
old 0.2 API.
* [**New**] openmpt123: openmpt123 can now open M3U, M3U8, M3UEXT, M3U8EXT and
PLSv2 playlists via the `--playlist` option.
* [**New**] openmpt123: openmpt123 now supports very fast file header probing
via the `--probe` option.
* [**New**] Libopenmpt now supports building for Windows 10 Universal (Windows
Store 8.2) APIs with MSVC, and also for the older Windows Runtime APIs with
MinGW-w64.
* [**New**] New API header `libopenmpt_ext.h` which implements the libopenmpt
extension APIs also for the C interface.
* [**New**] The Reverb effect (S99 in S3M/IT/MPTM, and X99 in XM) is now
implemented in libopenmpt.
* [**New**] For Amiga modules, a new resampler based on the Amiga's sound
characteristics has been added. It can be activated by passing the
`render.resampler.emulate_amiga` ctl with a value of `1`. Non-Amiga modules
are not affected by this, and setting the ctl overrides the resampler choice
specified by `OPENMPT_MODULE_RENDER_INTERPOLATIONFILTER_LENGTH` or
`openmpt::module::RENDER_INTERPOLATIONFILTER_LENGTH`. Support for the MOD
command E0x (Set LED Filter) is also available when the Amiga resampler is
enabled.
* [**Change**] libopenmpt versioning changed and follows the more conventional
major.minor.patch as well as the recommendations of the
[SemVer](http://semver.org/) scheme now. In addition to the SemVer
requirements, pre-1.0.0 versions will also honor API and ABI stability in
libopenmpt (i.e. libopenmpt ignores SemVer Clause 4).
* [**Change**] The output directories of the MSVC build system were changed to
`bin/vs2015-shared/x86-64-win7/` (and similar) layout which allows building
in the same tree with different compiler versions without overwriting other
outputs.
* [**Change**] The emscripten build now exports libopenmpt as 'libopenmpt'
instead of the default 'Module'.
* [**Change**] Android: The build system changed. The various Android.mk files
have been merged into a single one which can be controlled using command
line options.
* [**Change**] The `Makefile` build system now passes `std=c++11` to the
compiler by default. Older compilers may still work if you pass
`STDCXX=c++0x` to the `make` invocation.
* [**Change**] The `Makefile` option `ANCIENT=1` is gone.
* [**Change**] The optional dependencies on `libltdl` or `libdl` are gone.
They are no longer needed for any functionality.
* [**Regression**] Compiling client code using the C++ API now requires a
compiler running in C++11 mode.
* [**Regression**] Support for GCC 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7 has been
removed.
* [**Regression**] Support for Clang 3.0, 3.1, 3.2, 3.3 has been removed.
* [**Regression**] Support for Emscripten versions older than 1.31.0 has been
removed.
* [**Regression**] Support for Android NDK versions older than 11 has been
removed.
* [**Regression**] Visual Studio 2008, 2010, 2012, 2013 support has been
removed.
* [**Regression**] Dynamic run-time loading of libmpg123 is no longer
supported. Libmpg123 must be linked at link-time now.
* [**Regression**] xmp-openmpt: xmp-openmpt now requires XMPlay 3.8 or later
and compiling xmp-openmpt requires an appropriate XMPlay SDK with
`XMPIN_FACE` >= `4`.
* [**Regression**] Support for libmpg123 older than 1.13.0 has been removed.
* [**Regression**] Un4seen unmo3 support has been removed.
* [**Bug**] C++ API: `openmpt::exception` did not define copy and move
constructors or copy and move assignment operators in libopenmpt 0.2. The
compiler-generated ones were not adequate though. libopenmpt 0.3 adds the
appropriate special member functions. This adds the respective symbol names
to the exported ABI, which, depending on the compiler, might or might not
have been there in libopenmpt 0.2. The possibly resulting possible ODR
violation only affects cases that did crash in the libopenmpt 0.2 API anyway
due to memory double-free, and does not cause any further problems in
practice for all known platforms and compilers.
* [**Bug**] The C API could crash instead of failing gracefully in
out-of-memory situations.
* [**Bug**] The test suite could fail on MacOSX or FreeBSD in non-fatal ways
when no locale was active.
* [**Bug**] `libopenmpt_stream_callbacks_fd.h` and
`libopenmpt_stream_callbacks_file.h` were missing in Windows development
packages.
* [**Bug**] libopenmpt on Windows did not properly guard against current
working directory DLL injection attacks.
* [**Bug**] localtime() was used to determine the version of Schism Tracker
used to save IT and S3M files. This function is not guaranteed to be
thread-safe by the standard and is now no longer used.
* [**Bug**] Possible crashes with malformed IT, ITP, AMS, MDL, MED, MPTM, PSM
and Startrekker files.
* [**Bug**] Possible hangs with malformed DBM, MPTM and PSM files.
* [**Bug**] Possible hangs with malformed files containing cyclic plugin
routings.
* [**Bug**] Excessive loading times with malformed ITP / truncated AMS files.
* [**Bug**] Plugins did not work correctly when changing the sample rate
between two render calls.
* [**Bug**] Possible NULL-pointer dereference read during obscure
out-of-memory situations while handling exceptions in the C API.
* [**Bug**] libmodplug: `libmodplug.pc` was wrong.
* [**Bug**] Cross-compiling libopenmpt with autotools for Windows now properly
sets `-municode` and `-mconsole` as well as all required Windows system
libraries.
* [**Bug**] foo_openmpt: Interpolation filter and volume ramping settings were
confused in previous versions. This version resets both to the defaults.
* [**Bug**] libmodplug: The CSoundFile::Read function in the emulated
libmodplug C++ API returned the wrong value, causing qmmp (and possibly
other software) to crash.
* Support for SoundTracker Pro II (STP) and Digital Tracker (DTM) modules.
* Increased accuracy of the sample position and sample rate to drift less when
playing very long samples.
* Various playback improvements for IT and XM files.
* Channel frequency could wrap around after some excessive portamento / down
in some formats since libopenmpt 0.2-beta17.
* Playback improvements for S3M files made with Impulse Tracker and
Schism Tracker.
* ParamEq plugin emulation didn't do anything at full gain (+15dB).
* All standard DMO effects are now also emulated on non-Windows and non-MSVC
systems.
* Added `libopenmpt_stream_callbacks_buffer.h` which adds
`openmpt_stream_callbacks` support for in-memory buffers, possibly even only
using a truncated prefix view into a bigger file which is useful for
probing.
* Avoid enabling some ProTracker-specific quirks for MOD files most likely
created with ScreamTracker 3.
* Tremolo effect only had half the intended strength in MOD files.
* Pattern loops ending on the last row a pattern were not executed correctly
in S3M files.
* Work-around for reading MIDI macros and plugin settings in some malformed IT
files written by old UNMO3 versions.
* Improve tracker detection in IT format.
* Playback fixes for 8-channel MED files
* Do not set note volume to 0 on out-of-range offset in XM files.
* Better import of some slide commands in SFX files.
* Sample 15 in "Crew Generation" by Necros requires short loops at the
beginning of the sample to not be ignored. Since we need to ignore them in
some (non-ProTracker) modules, we heuristically disable the old loop
sanitization behaviour based on the module channel count.
* Both normal and percentage offset in PLM files were handled as percentage
offset.
* MT2 files with instruments that had both sample and plugin assignments were
not read correctly.
* Some valid FAR files were rejected erroneously.
* Support for VBlank timing flag and comment field in PT36 files.
* Improved accuracy of vibrato command in DIGI / DBM files.
* STM: Add support for "WUZAMOD!" magic bytes and allow some slightly
malformed STM files to load which were previously rejected.
* Detect whether "hidden" patterns in the order list of SoundTracker modules
should be taken into account or not.
* Tighten heuristics for rejecting invalid 669, M15, MOD and ICE files and
loosen them in other places to allow some valid MOD files to load.
* Improvements to seeking: Channel panning was not always updated from
instruments / samples when seeking, and out-of-range global volume was not
applied correctly in some formats.
* seek.sync_samples=1 did not apply PTM reverse offset effect and the volume
slide part of combined volume slide + vibrato commands.
* If the order list was longer than 256 items and there was a pattern break
effect without a position jump on the last pattern of the sequence, it did
not jump to the correct restart order.
* `Makefile` has now explicit support for FreeBSD with no special option or
configuration required.
* openmpt123: Improved section layout in man page.
* libmodplug: Added all missing C++ API symbols that are accessible via the
public libmodplug header file.
* Autotools build system now has options `--disable-openmpt123`,
`--disable-tests` and `--disable-examples` which may be desireable when
cross-compiling.
* Windows binary packages now ship with libmpg123 included.
### libopenmpt 0.2-beta20 (2016-08-07)
* [**Bug**] PSM loader was broken on big-endian platforms since forever.
* [**Bug**] `load.skip_samples` ctl did not work for PSM16 modules.
* There is a new `subsong` ctl, which can return the currently selected
subsong.
* More accurate ProTracker arpeggio wrap-around emulation.
* More accurate sample tuning in PSM16 files.
* Samples in DSM files were sometimes detuned and some pattern commands were
not imported correctly.
* More accurate import of MDL 7-bit panning command.
* Only import pattern commands supported by the UltraTracker version that was
used to save ULT files. Add support for command 5-C (end loop).
* DMF sample loop lengths were off by one.
* Unis 669 pan slide effect was too deep.
* Several valid (but slightly corrupted possibly due to disk failures or data
transfer errors) SoundTracker files were no longer loading since libopenmpt
0.2-beta18.
### libopenmpt 0.2-beta19 (2016-07-23)
* [**Change**] libopenmpt now uses C++14 `[[deprecated]]` attribute instead
of compiler-specific solutions when appropriate.
* [**Change**] libopenmpt C++ header now uses C++11 `noexcept` instead of
C++98 `throw()` exception specification when supported. `throw()` is
deprecated since C++11. This does not change API or ABI as they are
equivalent. Use `LIBOPENMPT_ASSUME_CPLUSPLUS_NOEXCEPT` to override the
default.
* [**Change**] The preprocessor macro `LIBOPENMPT_ANCIENT_COMPILER_STDINT` is
gone. Please use `LIBOPENMPT_ASSUME_CPLUSPLUS_CSTDINT instead`.
Additionally, the typedefs moved from illegal namespace ::std into somewhat
less dangerous namespace ::openmpt::std. You can test
`#ifdef LIBOPENMPT_QUIRK_NO_CSTDINT` client-side to check whether
`libopenmpt.hpp` used the non-standard types. (Note: Of all supported
compilers, this change only affects the 3 compilers with only limited
support: MSVC 2008, GCC 4.1, GCC 4.2.)
* [**Bug**] xmp-openmpt: Crash when viewing sample texts.
* The public libopenmpt C++ header has auto-detection logic for the used C++
standard now. In case your client code compiler misreports the standard
version or you want to override it for other reasons,
`#define LIBOPENMPT_ASSUME_CPLUSPLUS` to the value of the standard version
you desire to be used. There is also a macro for each individual aspect,
like `LIBOPENMPT_ASSUME_CPLUSPLUS_CSTDINT`,
`LIBOPENMPT_ASSUME_CPLUSPLUS_DEPRECATED`,
`LIBOPENMPT_ASSUME_CPLUSPLUS_NOEXCEPT` which take precedence over the
general macro.
* Portamento with sample swap behaviour was wrong for ProTracker MODs.
* Rewritten loader and various playback fixes for MDL files.
* libopenmpt 0.2-beta18 broke import of many pattern commands in DBM, DMF and
ULT files.
* ADPCM samples in MOD files were broken since libopenmpt 0.2-beta17.
### libopenmpt 0.2-beta18 (2016-07-11)
* [**Change**] openmpt123: Add PulseAudio output support. Autotools and
`Makefile` build systems now depend on `libpulse` and `libpulse-simple` by
default. Disable with `--without-pulseaudio` or `NO_PULSEAUDIO=1`
respectively. When enabled, PulseAudio will be the default output driver,
* [**Change**] xmp-openmpt: Settings are now stored in xmplay.ini like with
every other plugin.
* [**Regression**] openmpt123: Support for FLAC < 1.3.0 has been removed. FLAC
before 1.3.0 is broken beyond repair as it provides `assert.h` in the
include path.
* [**Bug**] Generated pkg-config file libopenmpt.pc by both `Makefile` and
Autotools build systems was totally broken.
* [**Bug**] libopenmpt no longer uses the non-thread-safe global std::rand()
function.
* [**Bug**] Sample loops in GDM modules did not work when using Emscripten.
* [**Bug**] XM and MO3 loaders could crash due to unaligned memory accesses.
* [**Bug**] Fixed incorrect handling of custom MPTM tunings on big endian
platforms.
* [**Bug**] Fixed various problems found with clang 3.8 static analyzer,
address sanitizer and undefined behaviour sanitizer.
* [**Bug**] File header probing functionality was broken for most formats.
* [**Bug**] With non-seekable streams, the entire file was almost always
cached even if it was not of any supported module type.
* Seeking in allsubsongs-mode now works correctly.
* openmpt123: Added subsong support.
* Various playback fixes for 669, IT, MT2 and MTM files.
* Some MOD files with more than 128 patterns (e.g. NIETNU.MOD) were not loaded
correctly.
* A new example `libopenmpt_example_c_probe` has been added which demonstrates
the usage and flexibility of openmpt_could_open_propability() in the C API
under various constraints.
### libopenmpt 0.2-beta17 (2016-05-21)
* [**Change**] The Makefile and Autotools build systems now require to
explicitly specify `NO_LTDL=1` or `--without-ltdl` respectively if no
support for dynamic loading of third party libraries via libtool libltdl is
desired.
* [**Change**] In the Makefile build system option `USE_MO3` and the Autotools
build system option `--enable-mo3` are gone. Dynamic loading of un4seen
unmo3 is now always enabled when dynamic loading is possible and built-in
MO3 support is not possible because either a MP3 or a Vorbis decoder is
missing.
* [**Change**] The MSVC build system changed. The `libopenmptDLL` project is
gone. Use the new `ReleaseShared` configuration of the `libopenmpt` project
instead. libopenmpt now links against zlib by default. A separate project
with smaller footprint linking against miniz is still available as
`libopenmpt-small`.
* [**Change**] The constants used to query library information from
`openmpt_get_string()` and `openmpt::string::get()` (i.e. OPENMPT_STRING_FOO
and openmpt::string::FOO) have been deprecated because having syntactic
constants for theses keys makes extending the API in a backwards and
forwards compatible way harder than it should be. Please just use the string
literals directly.
* [**Change**] Deprecated API identifiers will now cause deprecation warnings
with MSVC, GCC and clang. `#define LIBOPENMPT_NO_DEPRECATE` to disable the
warnings.
* [**Change**] openmpt123: `--[no-]shuffle` option has been renamed to
`--[no-]randomize`. A new `--[no-]shuffle` option has been added which
shuffles randomly through the playlist as opposed to randomizing the
playlist upfront.
* [**Change**] Support for Un4seen unmo3 has generally been deprecated in
favour of the new internal mo3 decoder. Un4seen unmo3 support will be
removed on 2018-01-01.
* [**Bug**] Memory consumption during loading has been reduced by about 1/3 in
case a seekable input stream is provided (either via C API callback open
functions or via C++ API iostream constructors).
* [**Bug**] Some samples in AMS modules were detuned when using Emscripten.
* [**Bug**] Possible crash with excessive portamento down in some formats.
* [**Bug**] Possible crashes with malformed AMF, AMS, DBM, IT, MDL, MED, MPTM,
MT2, PSM and MMCMP-, XPK- and PP20-compressed files.
* [**Bug**] `openmpt::module::format_pattern_row_channel` with `width == 0`
was returning an empty string instead of an string with unconstrained
length.
* Support for ProTracker 3.6 IFF-style modules and SoundFX / MultiMedia Sound
(SFX / MMS) modules.
* libopenmpt now has support for DMO plugins on Windows when built with MSVC.
Additionally, the DMO Compression, Distortion, Echo, Gargle, ParamEQ and
WavesReverb DSPs are emulated on on all other platforms.
* libopenmpt now supports the DigiBooster Echo DSP.
* To avoid any of the aforementioned plugins to be used, the load.skip_plugins
ctl can be passed when loading a module.
* libopenmpt got native MO3 support with MP3 decoding either via libmpg123 or
MediaFoundation (on Windows 7 and up) and Vorbis decoding via libogg,
libvorbis, libvorbisfile or stb_vorbis.
* libopenmpt MSVC builds with Visual Studio 2010 or later on Windows 7 or
later now use an internal MO3 decoder with libogg, libvorbis, libvorbisfile,
and libmpg123 or minimp3 or MediaFoundation suppport by default. Visual
Studio 2008 builds still use unmo3.dll by default but also support the
built-in decoder in which case libmpg123 is required.
* libopenmpt with Makefile or Autotools build system can now also use
glibc/libdl instead of libtool/libltdl for dynamic loading of third-party
libraries. Options `NO_DL=1` and `--without-dl` have been added
respectively.
* The `Makefile` build system got 4 new options NO_MPG123, NO_OGG, NO_VORBIS,
NO_VORBISFILE. The default is to use the new dependencies automatically.
* The `Autotools` build system got 4 new options --without-mpg123,
--without-ogg, --without-vorbis, --without-vorbisfile. The default is to use
the new dependencies automatically.
* Makefile and Android builds got support for using minimp3 instead of
libmpg123. For Android, use `Android-minimp3-stbvorbis.mk`, for Makefile use
`USE_MINIMP3=1`. You have to download
[minimp3](http://keyj.emphy.de/minimp3/) yourself and put its contents into
`include/minimp3/`.
* `"source_url"`, `"source_date"` and `"build_compiler"` keys have been added
to `openmpt_string_get()` and `openmpt::string::get()`.
* openmpt123: Add new `--[no-]restart]` option which restarts the playlist
when finished.
* Improved Ultimate SoundTracker version detection heuristics.
* Playing a sample at a sample rate close to the mix rate could lead to small
clicks when using vibrato.
* More fine-grained internal legacy module compatibility settings to correctly
play back modules made with older versions of OpenMPT and a few other
trackers.
* The tail of compressed MDL samples was slightly off.
* Some probably hex-edited XM files (e.g. cybernostra weekend.xm) were not
loaded correctly.
* Countless other playback fixes for MOD, XM, S3M, IT and MT2 files.
### libopenmpt 0.2-beta16 (2015-11-22)
* [**Change**] The Autotools build system does strict checking of all
dependencies now. Instead of best effort auto-magic detection of all
potentially optional dependencies, the default set of dependencies is now
enforced unless each individual dependency gets explicitely disabled via
`--without-foo` or `--disable-foo` `./configure` switches. Run
`./configure --help` for the full list of options.
* [**Bug**] Some MOD files were erroneously detected as 669 files.
* [**Bug**] Some malformed AMF files could result in very long loading times.
* [**Bug**] Fixed crashes in IMF and MT2 loaders.
* [**Bug**] MTM files generated by UNMO3 were not loaded properly.
* Improved MTM playback.
* `make CONFIG=haiku` for Haiku has been added.
* Language bindings for FreeBASIC have been added (see
`libopenmpt/bindings/`).
### libopenmpt 0.2-beta15 (2015-10-31)
* [**Change**] openmpt123: SDL2 is now supported and preferred to SDL1 if
available with the `Makefile` build system.
* [**Bug**] Emscripten support for older emscripten versions broke in -beta14.
These are now supported again when using `make CONFIG=emscripten-old`.
* [**Bug**] Fixed crashes in MED loader.
* Playback improvements and loader fixes for MOD, MT2 and MED.
### libopenmpt 0.2-beta14 (2015-09-13)
* [**Change**] The C++ API example now uses the PortAudio C++ bindings
instead of the C API.
* [**Change**] Default compiler options for Emscripten have been changed to
more closely match the Emscripten recommendations.
* [**Bug**] Client code compilation with C89 compilers was broken in beta13.
* [**Bug**] Test suite failed on certain Emscripten/node.js combinations.
* [**Bug**] Fixed various crashes or hangs in DMF, OKT, PLM, IT and MPTM
loaders.
* Implemented error handling in the libopenmpt API examples.
* Various playback improvements and fixes for OKT, IT and MOD.
### libopenmpt 0.2-beta13 (2015-08-16)
* [**Change**] The MSVC build system has been redone. Solutions are now
located in `build/vsVERSION/`.
* [**Bug**] get_current_channel_vu_left and get_current_channel_vu_right only
return the volume of the front left and right channels now.
get_current_channel_vu_rear_left and get_current_channel_vu_rear_right
do now actually work and return non-zero values.
* [**Bug**] Fix crashes and hangs in MED and MDL loaders and with some
truncated compressed IT samples.
* [**Bug**] Fix crash when playing extremely high-pitched samples.
* Completed C and C++ documentation
* Added new key for openmpt::module::get_metadata, "message_raw", which
returns an empty string if there is no song message rather than a list of
instrument names.
* in_openmpt: Support for compiling with VS2008.
* xmp-openmpt: Support for compiling with VS2008.
* in_openmpt: Add a more readable file information window.
### libopenmpt 0.2-beta12 (2015-04-19)
* Playback fix when row delay effect is used together with offset command.
* A couple of fixes for the seek.sync_samples=1 case.
* IT compatibility fix for IT note delay.
* ProTracker MOD playback compatibility improvement.
### libopenmpt 0.2-beta11 (2015-04-18)
* [**Change**] openmpt_stream_seek_func() now gets called with
OPENMPT_STREAM_SEEK_SET, OPENMPT_STREAM_SEEK_CUR and
OPENMPT_STREAM_SEEK_END whence parameter instead of SEEK_SET, SEEK_CUR and
SEEK_END. These are defined to 0, 1 and 2 respectively which corresponds to
the definition in all common C libraries. If your C library uses different
constants, this theoretically breaks binary compatibility. The old
libopenmpt code, however, never actually called the seek function, thus,
there will be no problem in practice.
* [**Change**] openmpt123: When both SDL1.2 and PortAudio are available,
SDL is now the preferred backend because SDL is more widespread and better
tested on all kinds of different platforms, and in general, SDL is just
more reliable.
* [**Bug**] libopenmpt now also compiles with GCC 4.3.
* libopenmpt now supports PLM (Disorder Tracker 2) files.
* Various playback improvements and fixes for IT, S3M, XM, MOD, PTM and 669
files.
### libopenmpt 0.2-beta10 (2015-02-17)
* [**Change**] Makefile configuration filenames changed from
`build/make/Makefile.config.*` to `build/make/config-*.mk`.
* [**Change**] libopenmpt for Android now supports unmo3 from un4seen. See
`build/android_ndk/README.AndroidNDK.txt` for details.
* [**Bug**] Fix out-of-bounds read in mixer code for ProTracker-compatible
MOD files which was introduced back in r4223 / beta6.
* Vibrato effect was too weak in beta8 and beta9 in IT linear slide mode.
* Very small fine portamento was wrong in beta8 and beta9 in IT linear slide
mode.
* Tiny IT playback compatibility improvements.
* STM playback improvements.
### libopenmpt 0.2-beta9 (2014-12-21)
* [**Bug**] libopenmpt_ext.hpp was missing from the Windows binary zip files.
### libopenmpt 0.2-beta8 (2014-12-21)
* [**Change**] foo_openmpt: Settings are now accessible via foobar2000
advanced settings.
* [**Change**] Autotools based build now supports libunmo3. Specify
--enable-unmo3.
* [**Change**] Support for dynamic loading of libunmo3 on MacOS X.
* [**Change**] libopenmpt now uses libltld (from libtool) for dynamic loading
of libunmo3 on all non-Windows platforms.
* [**Change**] Support for older compilers:
* GCC 4.1.x to 4.3.x (use `make ANCIENT=1`)
* Microsoft Visual Studio 2008 (with latest Service Pack)
(see `build/vs2008`)
* [**Change**] libopenmpt_ext.hpp is now distributed by default. The API is
still considered experimental and not guaranteed to stay API or ABI
compatible.
* [**Change**] xmp-openmpt / in_openmpt: No more libopenmpt_settings.dll.
The settings dialog now uses a statically linked copy of MFC.
* [**Bug**] The -autotools tarballs were not working at all.
* Vastly improved MT2 loader.
* Improved S3M playback compatibility.
* Added openmpt::ext::interactive, an extension which adds a whole bunch of
new functionality to change playback in some way or another.
* Added possibility to sync sample playback when using
openmpt::module::set_position_* by setting the ctl value
seek.sync_samples=1
* Support for "hidden" subsongs has been added.
They are accessible through the same interface as ordinary subsongs, i.e.
use openmpt::module::select_subsong to switch between any kind of subsongs.
* All subsongs can now be played consecutively by passing -1 as the subsong
index in openmpt::module::select_subsong.
* Added documentation for a couple of more functions.
### libopenmpt 0.2-beta7 (2014-09-07)
* [**Change**] libopenmpt now has an GNU Autotools based build system (in
addition to all previously supported ways of building libopenmpt).
Autotools support is packaged separately as tarballs ending in
`-autotools.tar.gz`.
* [**Bug**] The distributed windows .zip file did not include pugixml.
* [**Regression**] openmpt123: Support for writing WavPack (.wv) files has
been removed.
Reasoning:
1. WavPack support was incomplete and did not include support for writing
WavPack metadata at all.
2. openmpt123 already supports libSndFile which can be used to write
uncompressed lossless WAV files which can then be encoded to whatever
format the user desires with other tools.
### libopenmpt 0.2-beta6 (2014-09-06)
* [**Change**] openmpt123: SDL is now also used by default if availble, in
addition to PortAudio.
* [**Change**] Support for emscripten is no longer experimental.
* [**Change**] libopenmpt itself can now also be compiled with VS2008.
* [**Bug**] Fix all known crashes on platforms that do not support unaligned
memory access.
* [**Bug**] openmpt123: Effect column was always missing in pattern display.
### libopenmpt 0.2-beta5 (2014-06-15)
* [**Change**] Add unmo3 support for non-Windows builds.
* [**Change**] Namespace all internal functions in order to allow statically
linking against libopenmpt without risking duplicate symbols.
* [**Change**] Iconv is now completely optional and only used on Linux
systems by default.
* [**Change**] Added libopenmpt_example_c_stdout.c, an example without
requiring PortAudio.
* [**Change**] Add experimental support for building libopenmpt with
emscripten.
* [**Bug**] Fix ping-pong loop behaviour which broke in 0.2-beta3.
* [**Bug**] Fix crashes when accessing invalid patterns through libopenmpt
API.
* [**Bug**] Makefile: Support building with missing optional dependencies
without them being stated explicitely.
* [**Bug**] openmpt123: Crash when quitting while playback is stopped.
* [**Bug**] openmpt123: Crash when writing output to a file in interactive UI
mode.
* [**Bug**] openmpt123: Wrong FLAC output filename in --render mode.
* Various smaller playback accuracy improvements.
### libopenmpt 0.2-beta4 (2014-02-25)
* [**Bug**] Makefile: Dependency tracking for the test suite did not work.
### libopenmpt 0.2-beta3 (2014-02-21)
* [**Change**] The test suite is now built by default with Makefile based
builds. Use `TEST=0` to skip building the tests. `make check` runs the test
suite.
* [**Bug**] Crash in MOD and XM loaders on architectures not supporting
unaligned memory access.
* [**Bug**] MMCMP, PP20 and XPK unpackers should now work on non-x86 hardware
and implement proper bounds checking.
* [**Bug**] openmpt_module_get_num_samples() returned the wrong value.
* [**Bug**] in_openmpt: DSP plugins did not work properly.
* [**Bug**] in_openmpt/xmp-openmpt: Setting name for stereo separation was
misspelled. This version will revert your stereo separation settings to
default.
* [**Bug**] Crash when loading some corrupted modules with stereo samples.
* Support building on Android NDK.
* Avoid clicks in sample loops when using interpolation.
* IT filters are now done in integer instead of floating point. This improves
performance, especially on architectures with no or a slow FPU.
* MOD pattern break handling fixes.
* Various XM playback improvements.
* Improved and switchable dithering when using 16bit integer API.
### libopenmpt 0.2-beta2 (2014-01-12)
* [**Bug**] MT2 loader crash.
* [**Bug**] Saving settings in in_openmpt and xmp-openmpt did not work.
* [**Bug**] Load libopenmpt_settings.dll also from below Plugins directory in
Winamp.
* DBM playback improvements.
### libopenmpt 0.2-beta1 (2013-12-31)
* First release.
