 Changes from previous version of pkgconf
 ========================================
 
-Changes from 1.9.4 to 1.9.5:
-----------------------------
-
-* Fix incorrect assumptions involving the use of ctype(3) functions.
-  Patch by Taylor R Campbell.
-
-* Fix detection of provided functions on autoconf.
-  Patches by Harmen Stoppels.
-
-* Fix deletion of tests/meson.build by the autoconf build system.
-  Patch by h30032433.
-
-* Fix quoting rules in argvsplit.c.
-  Patch by huyubiao.
-
-* Update libpkgconf documentation and documentation building scripts.
-  Patches by Andrew Shadura.
-
-* Enforce maximum package count correctly for --modversion.
-
-Changes from 1.9.3 to 1.9.4:
-----------------------------
-
-* Fix a buffer overflow vulnerability involving very large variable expansions.
-  CVE-2023-24056
-
-* Fix a bunch of minor regressions with the solver.
-
-* Create separate solutions for `--cflags` and `--libs` when `--static` is not
-  used.
-
-* Remove final trailing whitespace in pkgconf_fragment_render_buf().
-
-* Revert broken pkg.m4 change involving querying module versions in
-  PKG_CHECK_MODULES.
-
-* Fix handling of tildes in version strings.
-
-* Various C99 formatting string fixes involving SIZE_FMT_SPECIFIER.
-
-Changes from 1.9.2 to 1.9.3:
-----------------------------
-
-* Fix a bunch of minor code issues pointed out using Clang static analyzer.
-
-* New API: pkgconf_solution_free(), which frees a compiled solution graph.
-
-* Fix behavior when overriding global variables with `--define-variable`.
-
-Changes from 1.9.1 to 1.9.2:
-----------------------------
-
-* Do not try to break dependency cycles across dependency lists.  This causes
-  the solved graph to sometimes miss required dependency nodes because the
-  solver detected an incorrect dependency cycle.
-
-* New API: pkgconf_queue_solve(), which replaces pkgconf_queue_apply().
-  pkgconf_queue_apply is now deprecated and should not be used in new code.
-
-Changes from 1.9.0 to 1.9.1:
-----------------------------
-
-* Skip graph flattening and traversal for query types which only make sense
-  for a single pkg-config module.
-
-  The old solver walked these graphs with --maximum-traverse-depth=1 in
-  these cases, but this is no longer helpful because the graph is flattened
-  by the new solver.
-
-Changes from 1.8.0 to 1.9.0:
-----------------------------
-
-* pkgconf 1.9.0 is the first testing release in the pkgconf 2.0 development
-  series.  While it is believed to be suitable for production, there may be
-  bugs due to the overall redesign of the solver and other initiatives.
-  Additionally, a future release of pkgconf plans will have additional ABI
-  breaks for the libpkgconf library before the pkgconf 2.0 release is cut.
-
-* There is now a new solver that is designed to provide higher performance
-  with complicated graphs, which works by flattening the dependency graph
-  into a smaller set of dependencies.  This graph can then be evaluated
-  instead of the original dependency graph without having to visit every
-  edge in the graph.
-
-  NOTE: This solver, while providing significant performance improvements,
-  does so, at the cost of changed behavior for some edge cases (such as
-  circular dependencies).
-
-* Bug fixes:
-  - Resolved several memory leaks with edge cases when using libpkgconf
-    directly.
-  - pkgconf CLI now consistently frees libpkgconf resources under all
-    circumstances.
-  - SYSROOT rules are no longer applied to `-uninstalled` packages by
-    default.  Use `PKG_CONFIG_PKGCONF1_SYSROOT_RULES` for legacy behavior.
-
-* A new `--license` selector has been added to the pkgconf CLI.  This uses
-  SPDX expressions which can be set as the `License` field in `.pc` files.
-  See the `pc(5)` manpage for more information.
-
-* The canonical location for pkgconf maintenance going forward is
-  <https://gitea.treehouse.systems/ariadne/pkgconf>.  This is presently
-  mirrored to GitHub for user convenience, but that mirroring will
-  be terminated at some point (due to GitHub Copilot).
-
-Changes from 1.7.4 to 1.8.0:
-----------------------------
-
-* This is the last planned maintenance branch.  I see pkgconf as basically
-  a finished tool at this point, and very few people were ultimately interested
-  in libpkgconf.  So, from here on out, it will just be bug fixes only and
-  very minor enhancements.
-
-* Bug fixes:
-  - Improved path handling on Windows to conform to what the MSYS2
-    and Cygwin teams were already modifying pkgconf to do.
-    Patches by Christoph Reiter.
-  - Fix a minor memory leak relating to cross-personalities.
-    Patch by Stone Tickle.
-  - Fix static builds for Windows on Meson.
-    Patch by Alexander Neumann.
-  - Fix some edge cases with --redefine-prefix.
-    Patch by midipix.
-  - Do not prepend sysroot_dir if the .pc file does not exist in the
-    sysroot.
-    Patch by Sandro Mani.
-  - Do not perform path filtering on default system include and library
-    path lists.  This fixes consistency with other mechanisms that modify
-    these path lists.
-
-* Enhancements:
-  - Document the --validate option in the manpage.
-    Patch by orbea.
-
-Changes from 1.7.3 to 1.7.4:
-----------------------------
-
-* Bug fixes:
-  - Fix null-dereference crash when pulling a malformed 'uninstalled'
-    .pc file into a dependency tree.  Patch by Tobias Stöckmann.
-  - Fix truncation of comment characters when quoted.
-  - Fix handling of .pc module names in --list-all on Windows.
-    Patch by Ryan Scott.
-  - Handle platforms where realpath(3) requires a pre-allocated buffer.
-    Patch by Fabian Groffen.
-  - Fix version whitespace warning.
-    Patch by Christoph Reiter.
-
-* Enhancements:
-  - Rewrite DOS paths on native Windows builds that don't use
-    Cygwin/MSYS.
-  - Add WantDefaultPure cross-compiler personality option.
-  - Prefer --static --pure linking on Windows.
-  - Add PKG_CONFIG_DONT_DEFINE_PREFIX environment variable.
-    Patch by Jeff Moguillansky.
-  - Many improvements when building pkgconf with Meson.
-    Patches by Christoph Reiter.
-
-Changes from 1.7.2 to 1.7.3:
-----------------------------
-
-* Bug fixes:
-  - Fix a possible out of boundary write when evaluating dependencies.
-    Patch by Tobias Stöckmann.
-  - Fix escaping logic on Windows.  Patch by Vincent Torri.
-  - Fix out of boundary reads and writes with a malformed fragment.
-    Patches by Tobias Stöckmann.
-  - Fix a possible out of boundary write when evaluating tuples.
-    Patch by Tobias Stöckmann.
-
-Changes from 1.7.1 to 1.7.2:
-----------------------------
-
-* Bug fixes:
-  - Fix a windows-specific crash relating to path fixups.
-
-Changes from 1.7.0 to 1.7.1:
-----------------------------
-
-* Bug fixes:
-  - Fix a possible out of boundary access in the parser for the
-    cross-compile database.  Patch by Tobias Stöckmann.
-  - Missing files for building with Meson are now included in the
-    tarball.  Patch by Neal Gompa.
-  - Fix calculation of package atoms on Windows with paths that
-    use both directory separator characters.
-
-Changes from 1.6.3 to 1.7.0:
-----------------------------
-
-* Bug fixes:
-  - Fix a possible buffer overflow involving newline escaping.
-    Patch by Tobias Stöckmann.
-  - Fix an out of boundary access in the parser.
-    Patch by Tobias Stöckmann.
-  - Fix leakage of strcmp() result value in pkgconf_compare_version()
-    responses.
-  - Return the default personality if loading a cross-compile
-    personality file failed.
-  - Do not complain about newlines when validating package versions.
-  - Properly detect strndup() on Windows when building with Meson.
-
-* Enhancements:
-  - A new --shared option and WantDefaultStatic cross-compile
-    configuration option have been added.  This allows for toolchains
-    to specify that static linking should be used by default.
-  - Support for the PKG_CONFIG_MSVC_SYNTAX environment variable has
-    been added.  Patch by Dan Kegel.

 As of the 1.1 series, pkgconf also fully implements support for `Provides` rules,

-Additionally, **we do not consider pkgconf doing what you tell it to do, in cases for

-If, for example, you use environment variables such as `PKG_CONFIG_SYSTEM_[INCLUDE|LIBRARY]_PATH`

-to those paths, it is not a `pkgconf` problem -- `pkgconf` is doing exactly what you told
-it to do.
