 Changes from previous version of pkgconf
 ========================================
 
-Changes from 2.1.1 to 2.2.0:
-----------------------------
-
-* libpkgconf SOVERSION is now 5.
-
-* Significant solver rework to flatten both requires and requires.private
-  dependencies in a single pass.  Improves performance slightly and ensures
-  proper dependency order.
-  Patches by Kai Pastor.
-
-* Improve `--digraph` output to reflect more of the solver's state in the
-  rendered dependency graph.
-  Patches by Kai Pastor.
-
-* Do not reference the graph root by name when presenting error messages about
-  directly requested dependency nodes.
-  Patch by Kai Pastor.
-
-Changes from 2.1.0 to 2.1.1:
-----------------------------
-
-* Documentation fixes from Sam James and Stefan Weil.
-
-* Fix --modversion with constraints.
-  Patch by Kai Pastor.
-
-* Reintroduce an optimization to the dependency graph walker which avoids
-  revisiting already visited nodes.
-  Patch by Yi Chou with some modifications.
-
-* Add a regression test to check that the dependency flattener is working
-  as expected.
-  Patch by Kai Pastor.
-
-Changes from 2.0.3 to 2.1.0:
-----------------------------
-
-* Do not flatten the solver solution into the original world used as
-  input to the solver.
-  Patches by Kai Pastor.
-
-* Fix warnings with GCC 14 -Walloc-size.
-  Patch by Sam James.
-
-* Add --solution to the pkgconf CLI to dump the solver state.
-
-* Improve the --digraph output to clarify cancelled edges in a given
-  solution.
-
-* Demote requires dependencies to requires.private when a parent
-  dependency is pulled in via requires.private.
-
-* Trim trailing whitespace when processing package arguments.
-  Patch by Colin Gillespie.
-
-* Avoid strncmp() in --modversion version comparison.
-  Patch by Colin Gillespie.
-
-* Update autoconf compile flag checking macro.
-  Patch by Peter Kokot.
-
-* Add system default path configuration to Meson.
-  Patch by L. E. Segovia.
-
-* Fix order of PKG_CONFIG_LIBDIR and PKG_CONFIG_PATH element processing.
-
-Changes from 2.0.2 to 2.0.3:
-----------------------------
-
-* Fix some edge-cases with the new `--modversion` implementation
-  and add additional regression tests.
-  Patch by Colin Gillespie.
-
-* Fix some format specifiers to use PRIu64 in debug tracing.
-
-Changes from 2.0.1 to 2.0.2:
-----------------------------
-
-* Fix long-standing bug where package identifiers for "uninstalled"
-  packages incorrectly included the "-uninstalled" suffix.
-
-  This was exposed by the recent change to `--modversion` in 2.0.1.
-
-Changes from 2.0.0 to 2.0.1:
-----------------------------
-
-* The behavior of --modversion was largely reverted back to the traditional
-  pkg-config behavior, but still operates on a solved dependency graph.
-
-  The order of --modversion output is based on the dependency resolution
-  queue which is passed to the solver, which itself generally maps to the
-  order of the constrants provided on the command line.
-
-* A new flag, --verbose, has been added.  When used with `--modversion`, it
-  is possible to disambiguate which version belongs to which module:
-
-    % pkgconf --modversion --verbose foo bar
-    foo: 1.2.3
-    bar: 1.3
-
-Changes from 1.9.5 to 2.0.0:
-----------------------------
-
-* When flattening the dependency graph, retain the latest seen edges
-  rather than the earliest.
-
-* Fix a long-standing bug where the dependency resolution queue was
-  evaluated in reverse.  This bug masked the aforementioned dependency
-  flattening bug in many cases.
-
-* Fix handling of --with-path, which was appending paths to the search
-  list rather than prepending them as intended.
-
-* Error when --modversion is requested with more than one package, as
-  the output is ambiguous.
-
 Changes from 1.9.4 to 1.9.5:
