 Note that the only difference between `v2` and `v3` of the CodeQL Action is the node version they support, with `v3` running on node 20 while we continue to release `v2` to support running on node 16. For example `3.22.11` was the first `v3` release and is functionally identical to `2.22.11`. This approach ensures an easy way to track exactly which features are included in different versions, indicated by the minor and patch version numbers.
 
+## 2.26.12 - 07 Oct 2024
+
+- _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.

 ## 2.26.11 - 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 to `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.

-### Permissions
+### Actions
+
+This repository contains several actions that enable you to analyze code in your repository using CodeQL and upload the analysis to GitHub Code Scanning. Actions in this repository also allow you to upload to GitHub analyses generated by any SARIF-producing SAST tool.
+
+Actions for CodeQL analyses:
+
+- `init`: Sets up CodeQL for analysis. For information about input parameters, see the [init action definition](https://github.com/github/codeql-action/blob/main/init/action.yml).
+- `analyze`: Finalizes the CodeQL database, runs the analysis, and uploads the results to Code Scanning. For information about input parameters, see the [analyze action definition](https://github.com/github/codeql-action/blob/main/analyze/action.yml).
+
+Actions for uploading analyses generated by third-party tools:
+
+- `upload-sarif`: Uploads a SARIF file to Code Scanning. If you are using the `analyze` action, there is no reason to use this action as well. For information about input parameters, see the [upload-sarif action definition](https://github.com/github/codeql-action/blob/main/upload-sarif/action.yml).
+
+Actions with special purposes and unlikely to be used directly:
+
+- `autobuild`: Attempts to automatically build the code. Only used for analyzing languages that require a build. Use the `build-mode: autobuild` input in the `init` action instead. For information about input parameters, see the [autobuild action definition](https://github.com/github/codeql-action/blob/main/autobuild/action.yml).
+- `resolve-environment`: [Experimental] Attempts to infer a build environment suitable for automatic builds. For information about input parameters, see the [resolve-environment action definition](https://github.com/github/codeql-action/blob/main/resolve-environment/action.yml).
+- `start-proxy`: [Experimental] Start the HTTP proxy server. Internal use only and will change without notice. For information about input parameters, see the [start-proxy action definition](https://github.com/github/codeql-action/blob/main/start-proxy/action.yml).
+
+### Workflow Permissions
 
 All advanced setup code scanning workflows must have the `security-events: write` permission. Workflows in private repositories must additionally have the `contents: read` permission. For more information, see "[Assigning permissions to jobs](https://docs.github.com/en/actions/using-jobs/assigning-permissions-to-jobs)."
 
+### Build Modes
+
+The CodeQL Action supports different build modes for analyzing the source code. The available build modes are:
+
+- `none`: The database will be created without building the source code. Available for all interpreted languages and some compiled languages.
+- `autobuild`: The database will be created by attempting to automatically build the source code. Available for all compiled languages.
+- `manual`: The database will be created by building the source code using a manually specified build command. To use this build mode, specify manual build steps in your workflow between the `init` and `analyze` steps. Available for all compiled languages.
+
+#### Which build mode should I use?
+
+Interpreted languages must use `none` for the build mode.
+
+For compiled languages:
+
+- `manual` build mode will typically produce the most precise results, but it is more difficult to set up and will cause the analysis to take slightly more time to run.
+- `autobuild` build mode is simpler to set up, but will only work for projects with generic build steps that can be guessed by the heuristics of the autobuild scripts. If `autobuild` fails, then you must switch to `manual` or `none`. If `autobuild` succeeds, then the results and run time will be the same as `manual` mode.
+- `none` build mode is also simpler to set up and is slightly faster to run, but there is a possibility that some alerts will be missed. This may happen if your repository does any code generation during compilation or if there are any dependencies downloaded from registries that the workflow does not have access to. `none` is not yet supported by C/C++, Swift, Go, or Kotlin.
