 - Fixed [a bug](https://github.com/github/codeql-action/issues/3555) which caused the CodeQL Action to fail loading repository properties if a "Multi select" repository property was configured for the repository. [#3557](https://github.com/github/codeql-action/pull/3557)
 - The CodeQL Action now loads [custom repository properties](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization) on GitHub Enterprise Server, enabling the customization of features such as `github-codeql-disable-overlay` that was previously only available on GitHub.com. [#3559](https://github.com/github/codeql-action/pull/3559)
 - Fixed the retry mechanism for database uploads. Previously this would fail with the error "Response body object should not be disturbed or locked". [#3564](https://github.com/github/codeql-action/pull/3564)
+- Added an experimental change which disables TRAP caching when [improved incremental analysis](https://github.com/github/roadmap/issues/1158) is enabled, since improved incremental analysis supersedes TRAP caching. This will improve performance and reduce Actions cache usage. We expect to roll this change out to everyone in March. [#3569](https://github.com/github/codeql-action/pull/3569)
