 - Downgrade default CodeQL bundle version to [2.24.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.3) due to issues with a small percentage of Actions and JavaScript analyses. [#3762](https://github.com/github/codeql-action/pull/3762)

 - 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)

File coverage information will still be computed on non-PR analyses. Pull request analyses will log a warning about this upcoming change. [#3562](https://github.com/github/codeql-action/pull/3562)

   To opt out of this change:
   - **Repositories owned by an organization:** Create a custom repository property with the name `github-codeql-file-coverage-on-prs` and the type "True/false", then set this property to `true` in the repository's settings. For more information, see [Managing custom properties for repositories in your organization](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization). Alternatively, if you are using an advanced setup workflow, you can set the `CODEQL_ACTION_FILE_COVERAGE_ON_PRS` environment variable to `true` in your workflow.
   - **User-owned repositories using default setup:** Switch to an advanced setup workflow and set the `CODEQL_ACTION_FILE_COVERAGE_ON_PRS` environment variable to `true` in your workflow.

 - Repositories owned by an organization can now set up the `github-codeql-disable-overlay` custom repository property to disable [improved incremental analysis for CodeQL](https://github.com/github/roadmap/issues/1158). First, create a custom repository property with the name `github-codeql-disable-overlay` and the type "True/false" in the organization's settings. Then in the repository's settings, set this property to `true` to disable improved incremental analysis.

 - Added an experimental change so that when [improved incremental analysis](https://github.com/github/roadmap/issues/1158) fails on a runner — potentially due to insufficient disk space — the failure is recorded in the Actions cache so that subsequent runs will automatically skip improved incremental analysis until something changes (e.g. a larger runner is provisioned or a new CodeQL version is released).

 - When SARIF files are uploaded by the `analyze` or `upload-sarif` actions, the CodeQL Action automatically performs post-processing steps to prepare the data for the upload. Previously, these post-processing steps were only performed before an upload took place. We are now changing this so that the post-processing steps will always be performed, even when the SARIF files are not uploaded. This does not change anything for the `upload-sarif` action. For `analyze`, this may affect Advanced Setup for CodeQL users who specify a value other than `always` for the `upload` input. [#3222](https://github.com/github/codeql-action/pull/3222)

These versions of CodeQL were discontinued on 24 September 2024 alongside GitHub Enterprise Server 3.10, and will be unsupported by CodeQL Action versions 3.27.0 and later and versions 2.27.0 and later. [#2520](https://github.com/github/codeql-action/pull/2520)
-
   - If you are using one of these versions, please update to CodeQL CLI version 2.14.6 or later. For instance, if you have specified a custom version of the CLI using the 'tools' input to the 'init' Action, you can remove this input to use the default version.
-
   - Alternatively, if you want to continue using a version of the CodeQL CLI between 2.13.5 and 2.14.5, you can replace `github/codeql-action/*@v3` by `github/codeql-action/*@v3.26.11` and `github/codeql-action/*@v2` by `github/codeql-action/*@v2.26.11` in your code scanning workflow to ensure you continue using this version of the CodeQL Action.
 
 ## 3.26.11 - 03 Oct 2024
 
 - _Upcoming breaking change_: Add support for using `actions/download-artifact@v4` to programmatically consume CodeQL Action debug artifacts.

   Starting November 30, 2024, GitHub.com customers will [no longer be able to use `actions/download-artifact@v3`](https://github.blog/changelog/2024-04-16-deprecation-notice-v3-of-the-artifact-actions/). Therefore, to avoid breakage, customers who programmatically download the CodeQL Action debug artifacts should set the `CODEQL_ACTION_ARTIFACT_V4_UPGRADE` environment variable to `true` and bump `actions/download-artifact@v3` to `actions/download-artifact@v4` in their workflows. The CodeQL Action will enable this behavior by default in early November and workflows that have not yet bumped `actions/download-artifact@v3` to `actions/download-artifact@v4` will begin failing then.
-
   This change is currently unavailable for GitHub Enterprise Server customers, as `actions/upload-artifact@v4` and `actions/download-artifact@v4` are not yet compatible with GHES.
