+## 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)
+
+### Miscellaneous
+
+- Windows binaries for the CodeQL CLI are now built with `/guard:cf`, enabling [Control Flow Guard](https://learn.microsoft.com/en-us/windows/win32/secbp/control-flow-guard).
+
+## Release 2.21.2 (2025-05-01)
+
+### Bugs fixed
+
+- `codeql generate log-summary` now correctly includes `dependencies`
+  maps in predicate events for `COMPUTED_EXTENSIONAL` predicates.
+
+## Release 2.21.1 (2025-04-22)
+
+### Bugs fixed
+
+- Fixed a bug in CodeQL analysis for GitHub Actions in the presence
+  of a code scanning configuration file containing `paths-ignore`
+  exclusion patterns but not `paths` inclusion patterns.
+  Previously, such a configuration incorrectly led to all YAML, HTML,
+  JSON, and JS source files being extracted,
+  except for those filtered by `paths-ignore`.
+  This in turn led to performance issues on large codebases.
+  Now, only workflow and Action metadata YAML files relevant to the
+  GitHub Actions analysis will be extracted,
+  except for those filtered by `paths-ignore`.
+  This matches the default behavior when no configuration file
+  is provided.
+  The handling of `paths` inclusion patterns is unchanged:
+  if provided, only those paths will be considered,
+  except for those filtered by `paths-ignore`.
+
+## Release 2.21.0 (2025-04-03)
+
+### Miscellaneous
+
+- On macOS the `CODEQL_TRACER_RELOCATION_EXCLUDE` environment variable can now be used to exclude certain paths from the
+  tracer relocation and tracing process. This environment variable accepts newline-separated regex patterns of binaries
+  to be excluded.  
+
+## Release 2.20.7 (2025-03-18)
+
+- There are no user-facing changes in this release.
+
+## Release 2.20.6 (2025-03-06)
+
+### Miscellaneous
+
+- The CodeQL XML extractor is now able to parse documents in a wider array of
+  character sets.
+
+- The build of Eclipse Temurin OpenJDK that is used to run the CodeQL
+  CLI has been updated to version 21.0.6.
+
+## Release 2.20.5 (2025-02-20)
+
+### Breaking changes
+
+- Removed support for `QlBuiltins::BigInt`s in the `avg()` aggregate.
+
+- A number of breaking changes have been made to the C and C++ CodeQL test environment as used by `codeql test run`:
+  - The `-Xclang-only=<arg>` option is no longer supported by `semmle-extractor-options`. Instead, when either `--clang` or `--clang_version` is specified the option should be replaced by `<arg>` only, otherwise the option should be omitted.
+  - The `--sys_include <arg>` and `--preinclude <arg>` options are no longer supported by `semmle-extractor-options`. Instead, `--edg <option_name> --edg <arg>` should be specified.
+  - The `-idirafter <arg>` option is no longer supported by `semmle-extractor-options`. Instead, `--edg --sys_include --edg <arg>` should be specified.
+  - The `-imacros <arg>` option is no longer supported by `semmle-extractor-options`. Instead, `--edg --preinclude_macros --edg <arg>` should be specified.
+  - The `/FI <arg>` option is no longer supported by `semmle-extractor-options`. Instead, `--edg --preinclude --edg <arg>` should be specified.
+  - The `-Wreserved-user-defined-literal`, `-Wno-reserved-user-defined-literal`, `-fwritable-strings`, `/Zc:rvalueCast`, `/Zc:rvalueCast-`, and `/Zc:wchar_t-` options are no longer supported by `semmle-extractor-options`. Instead, `--edg --reserved_user_defined_literal`, `--edg --no-reserved_user_defined_literal`, `--edg --no_const_string_literals`, `--edg --no_preserve_lvalues_with_same_type_casts`, `--edg --preserve_lvalues_with_same_type_casts`, and `--edg --no_wchar_t_keyword` should be specified, respectively.
+  - The `/Fo <arg>` option is no longer supported by `semmle-extractor-options`. The option should be omitted.
+
+## Release 2.20.4 (2025-02-06)
+
+### New features
+
+- Using the `actions` language (for analysis of GitHub Actions workflows) no longer requires
+  the `CODEQL_ENABLE_EXPERIMENTAL_FEATURES` environment variable to be set. Support for analysis
+  of GitHub Actions workflows remains in public preview.
+
+### Bugs fixed
+
+- Fixed a bug where CodeQL for Java would fail with an SSL exception while trying to download `maven`.
+
+### Miscellaneous
+
+- The build of the [logback-core](https://logback.qos.ch/) library that is used for logging in the CodeQL CLI has been updated to version 1.3.15.
+
+## Release 2.20.3 (2025-01-24)
+
+### Security Updates
+
+- Resolves a security vulnerability where CodeQL databases or logs produced by the CodeQL CLI may contain the environment variables from the time of
+  database creation. This includes any secrets stored in an environment variables. For more information, see the
+  [CodeQL CLI security advisory](https://github.com/github/codeql-cli-binaries/security/advisories/GHSA-gqh3-9prg-j95m).
+
+  All users of CodeQL should follow the advice in the CodeQL advisory mentioned above or upgrade to this version or a later version of CodeQL.
+
+  If you are using the CodeQL Action, also see the related [CodeQL Action security advisory](https://github.com/github/codeql-action/security/advisories/GHSA-vqf5-2xx6-9wfm).
+
+## Release 2.20.2 (2025-01-22)
+
+### Improvements
+
+- `codeql database create` and `codeql database finalize` now write relations to disk in a new, compressed format. As a result, databases will generally take up less space on disk, whether zipped or unzipped. Note that databases in this format can only be read and analyzed using CodeQL version 2.20.1 onwards. Attempting to analyze such a database with CodeQL version 2.20.0 or older will fail, with an error message like the following:
+  ```
+  UnsortedExtensionalError: Tuples that were assumed to be in order are not: [123456777, 777654321, 123456777]<[777654321, 123456777, 777654321]
+  ```
+
+### Enhancements
+
+- Added the `.bitLength()` method to `QlBuiltins::BigInt`.
+
+### Bugs Fixed
+
+- Fixed a bug where CodeQL would crash on rare occasions while merging SARIF files before uploading results.
+
+## Release 2.20.1 (2025-01-09)
+
+### Improvements
+
+- Automatic installation of dependencies for C++ autobuild is now supported on Ubuntu 24.04.
+
+- The CLI will now warn if it detects that it is installed in a
+  location where it is likely to cause performance issues. This
+  includes: user home, desktop, downloads, or the file system root.
+
+  You can avoid this warning by setting the `CODEQL_ALLOW_INSTALLATION_ANYWHERE`
+  environment variable to `true`.
+
+## Release 2.20.0 (2024-12-09)
+
+### Known issues
+
+- The Windows executable for this release is labeled with an incorrect version number
+  within its properties: the version number should be 2.20.0 rather than 2.19.4.
+  `codeql version` reports the correct version number.
+
+### New features
+
+- The [`QlBuiltins::BigInt` type](https://codeql.github.com/docs/ql-language-reference/modules/#bigint) of
+  arbitrary precision integers is generally available and no longer hidden behind the
+  `--allow-experimental=bigint` CLI feature flag.
+
+### Miscellaneous
+
+- Backslashes are now escaped when writing output in the Graphviz DOT format (`--format=dot`).
+- The build of Eclipse Temurin OpenJDK that is used to run the CodeQL CLI has been updated to version
+  21.0.5.
+
