See the [releases page](https://github.com/github/codeql-action/releases) for the relevant changes to the CodeQL CLI and language packs.

- Update default CodeQL bundle version to [2.24.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.3). [#3548](https://github.com/github/codeql-action/pull/3548)

- 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. 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). This feature is not yet available on GitHub Enterprise Server. [#3507](https://github.com/github/codeql-action/pull/3507)

- 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). We expect to roll this change out to everyone in March. [#3487](https://github.com/github/codeql-action/pull/3487)

- Added an experimental change which allows the `start-proxy` action to resolve the CodeQL CLI version from feature flags instead of using the linked CLI bundle version. We expect to roll this change out to everyone in March. [#3512](https://github.com/github/codeql-action/pull/3512)

- The previously experimental changes from versions 4.32.3, 4.32.4, 3.32.3 and 3.32.4 are now enabled by default. [#3503](https://github.com/github/codeql-action/pull/3503), [#3504](https://github.com/github/codeql-action/pull/3504)

- Update default CodeQL bundle version to [2.24.2](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.2). [#3493](https://github.com/github/codeql-action/pull/3493)

- Added an experimental change which improves how certificates are generated for the authentication proxy that is used by the CodeQL Action in Default Setup when [private package registries are configured](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries). This is expected to generate more widely compatible certificates and should have no impact on analyses which are working correctly already. We expect to roll this change out to everyone in February. [#3473](https://github.com/github/codeql-action/pull/3473)

- When the CodeQL Action is run [with debugging enabled in Default Setup](https://docs.github.com/en/code-security/how-tos/scan-code-for-vulnerabilities/troubleshooting/troubleshooting-analysis-errors/logs-not-detailed-enough#creating-codeql-debugging-artifacts-for-codeql-default-setup) and [private package registries are configured](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries), the "Setup proxy for registries" step will output additional diagnostic information that can be used for troubleshooting. [#3486](https://github.com/github/codeql-action/pull/3486)

- Added a setting which allows the CodeQL Action to enable network debugging for Java programs. This will help GitHub staff support customers with troubleshooting issues in GitHub-managed CodeQL workflows, such as Default Setup. This setting can only be enabled by GitHub staff. [#3485](https://github.com/github/codeql-action/pull/3485)

- Added a setting which enables GitHub-managed workflows, such as Default Setup, to use a [nightly CodeQL CLI release](https://github.com/dsp-testing/codeql-cli-nightlies) instead of the latest, stable release that is used by default. This will help GitHub staff support customers whose analyses for a given repository or organization require early access to a change in an upcoming CodeQL CLI release. This setting can only be enabled by GitHub staff. [#3484](https://github.com/github/codeql-action/pull/3484)

- Added experimental support for testing connections to [private package registries](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries). This feature is not currently enabled for any analysis. In the future, it may be enabled by default for Default Setup. [#3466](https://github.com/github/codeql-action/pull/3466)

- Update default CodeQL bundle version to [2.24.1](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.1). [#3460](https://github.com/github/codeql-action/pull/3460)

- A warning is now shown in Default Setup workflow logs if a [private package registry is configured](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries) using a GitHub Personal Access Token (PAT), but no username is configured. [#3422](https://github.com/github/codeql-action/pull/3422)

- Fixed a bug which caused the CodeQL Action to fail when repository properties cannot successfully be retrieved. [#3421](https://github.com/github/codeql-action/pull/3421)

- Update default CodeQL bundle version to [2.24.0](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.0). [#3425](https://github.com/github/codeql-action/pull/3425)

- When running a Default Setup workflow with [Actions debugging enabled](https://docs.github.com/en/actions/how-tos/monitor-workflows/enable-debug-logging), the CodeQL Action will now use more unique names when uploading logs from the Dependabot authentication proxy as workflow artifacts. This ensures that the artifact names do not clash between multiple jobs in a build matrix. [#3409](https://github.com/github/codeql-action/pull/3409)

- Improved error handling throughout the CodeQL Action. [#3415](https://github.com/github/codeql-action/pull/3415)

- Added experimental support for automatically excluding [generated files](https://docs.github.com/en/repositories/working-with-files/managing-files/customizing-how-changed-files-appear-on-github) from the analysis. This feature is not currently enabled for any analysis. In the future, it may be enabled by default for some GitHub-managed analyses. [#3318](https://github.com/github/codeql-action/pull/3318)

- The changelog extracts that are included with releases of the CodeQL Action are now shorter to avoid duplicated information from appearing in Dependabot PRs. [#3403](https://github.com/github/codeql-action/pull/3403)

- Update default CodeQL bundle version to 2.23.9. [#3393](https://github.com/github/codeql-action/pull/3393)

No user facing changes.

- Update default CodeQL bundle version to 2.23.8. [#3354](https://github.com/github/codeql-action/pull/3354)

- Update default CodeQL bundle version to 2.23.7. [#3343](https://github.com/github/codeql-action/pull/3343)

No user facing changes.

- Update default CodeQL bundle version to 2.23.6. [#3321](https://github.com/github/codeql-action/pull/3321)

No user facing changes.

- CodeQL Action v3 will be deprecated in December 2026. The Action now logs a warning for customers who are running v3 but could be running v4. For more information, see [Upcoming deprecation of CodeQL Action v3](https://github.blog/changelog/2025-10-28-upcoming-deprecation-of-codeql-action-v3/).

- Update default CodeQL bundle version to 2.23.5. [#3288](https://github.com/github/codeql-action/pull/3288)

No user facing changes.

- The `add-snippets` input has been removed from the `analyze` action. This input has been deprecated since CodeQL Action 3.26.4 in August 2024 when this removal was announced.

- Bump minimum CodeQL bundle version to 2.17.6. [#3223](https://github.com/github/codeql-action/pull/3223)

- 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)

- Update default CodeQL bundle version to 2.23.3. [#3205](https://github.com/github/codeql-action/pull/3205)

- Experimental: A new `setup-codeql` action has been added which is similar to `init`, except it only installs the CodeQL CLI and does not initialize a database. Do not use this in production as it is part of an internal experiment and subject to change at any time. [#3204](https://github.com/github/codeql-action/pull/3204)

No user facing changes.

- _Upcoming breaking change_: Add a deprecation warning for customers using CodeQL version 2.14.5 and earlier. 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.

- _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.

- Update default CodeQL bundle version to 2.19.1. [#2519](https://github.com/github/codeql-action/pull/2519)

- The deprecated feature for extracting dependencies for a Python analysis has been removed. [#2224](https://github.com/github/codeql-action/pull/2224)

As a result, the following inputs and environment variables are now ignored:

- The `setup-python-dependencies` input to the `init` Action

- The `CODEQL_ACTION_DISABLE_PYTHON_DEPENDENCY_INSTALLATION` environment variable

We recommend removing any references to these from your workflows. For more information, see the release notes for CodeQL Action v3.23.0 and v2.23.0.

- Automatically overwrite an existing database if found on the filesystem. [#2229](https://github.com/github/codeql-action/pull/2229)

- Bump the minimum CodeQL bundle version to 2.12.6. [#2232](https://github.com/github/codeql-action/pull/2232)
