 ## [UNRELEASED]
 
 - This version of the CodeQL Action adds support for the `tools` input for the `codeql-action/init` step to be specified using a `github-codeql-tools` [repository property](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization). This feature will gradually be rolled out following the release of this version. Once rolled out, this allows for the CodeQL CLI version that is used in GitHub-managed workflows, such as Default Setup, to be set to a custom value. For example, customers who run into issues with rate limits when a new CodeQL CLI version is released can set the value to `toolcache` to always use the CodeQL CLI version that is available in the runner toolcache. For Advanced Setup workflows, the value provided for `tools` in the workflow definition always takes precedence unless the value of the repository property starts with `!`. [#4037](https://github.com/github/codeql-action/pull/4037)
+- Update default CodeQL bundle version to [2.26.2](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.2). [#4051](https://github.com/github/codeql-action/pull/4051)
