-- 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)
-- We are rolling out improved incremental analysis to C/C++ analyses that use build mode `none`. We expect this rollout to be complete by the end of April 2026. [#3584](https://github.com/github/codeql-action/pull/3584)
-- Update default CodeQL bundle version to [2.25.0](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.0). [#3585](https://github.com/github/codeql-action/pull/3585)
