+## Release 2.22.3 (2025-08-06)
+
+### New features
+
+- The `codeql database cleanup` command now takes the `--cache-cleanup=overlay`
+  option, which trims the cache to just the data that will be useful when
+  evaluating against an overlay.
+
+## Release 2.22.2 (2025-07-29)
+
+### Bug fix
+
+- Fixes a bug in query suites where the `version` property of an `import` instruction was ignored. Previously, the following query suite would _not_ resolve to `v1.0.19` of `codeql/csharp-queries`. Instead it would resolve to the latest version. This is now fixed and the resolve pack version would be `v1.0.19`.
+  ```
+   - from: codeql/csharp-queries
+     import: codeql-suites/csharp-security-and-quality.qls
+     version: 1.0.19
+  ```
+
+## Release 2.22.1 (2025-06-26)
+
+### New features
+
+- Rust language support is now in public preview.
+
+### Miscellaneous
+
+- The version of `jgit` used by the CodeQL CLI has been updated to `6.10.1.202505221210-r`.
+
+## Release 2.22.0 (2025-06-11)
+
+### Breaking changes
+
+- A number of breaking changes have been made to the C and C++ CodeQL test
+  environment as used by `codeql test run`:
+  - Options starting with a `/` are no longer supported by
+    `semmle-extractor-options`. Any option starting with a `/` should be
+    replaced by the equivalent option starting with a `-`, e.g., `/D` should be
+    replaced by `-D`.
+  - Preprocessor command line options of the form `-D<macro>#<def>` are no
+    longer supported by `semmle-extractor-options`. `-D<macro>=<def>` should be
+    used instead.
+  - The `/Fp` and `-o` options are no longer supported by
+    `semmle-extractor-options`. The options should be omitted.
+  - The `-emit-pch`, `-include-pch`, `/Yc`, and `/Yu` options, and the
+    `--preinclude` option taking a pre-compiled header as its argument, are no
+    longer supported by `semmle-extractor-options`. Any test that makes use of
+    this should be replaced by a test that invokes the CodeQL CLI with the
+    `create database` option and that runs the relevant queries on the created
+    database.
+
+## Release 2.21.4 (2025-06-02)
+
+### Deprecations
+
+- The `clang_vector_types`, `clang_attributes`, and `flax-vector-conversions` command
+  line options have been removed from the C/C++ extractor. These options were introduced
+  as workarounds to frontend limitations in earlier versions of the extractor and are
+  no longer needed when calling the extractor directly.
+
+### Miscellaneous
+
+- The build of Eclipse Temurin OpenJDK that is used to run the CodeQL
+  CLI has been updated to version 21.0.7.
+
 ## Release 2.21.3 (2025-05-15)
