 Changes from previous version of pkgconf
 ========================================
 
-Changes from 1.8.0 to 1.8.1:
+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).
