-## 4.37.6 - 04 Aug 2026
-
- Changed the default filepath for the new remote file address format that was introduced in CodeQL Action 4.37.0 / 3.37.0 to `.github/codeql-config.yml` to align it with the suggested path that is used elsewhere. [#4070](https://github.com/github/codeql-action/pull/4070)
-
-## 4.37.5 - 03 Aug 2026
-
- Fixed a bug where a network error while streaming the download of the CodeQL bundle could terminate the `init` Action instead of falling back to downloading the bundle before extracting it. [#4061](https://github.com/github/codeql-action/pull/4061)
-
 ## 4.37.4 - 29 Jul 2026

 - 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 `!`.
