 # CodeQL Action and CodeQL Runner Changelog
 
+## 1.0.22 - 04 Nov 2021
+
+- The `init` step of the Action now supports `ram` and `threads` inputs to limit resource use of CodeQL extractors. These inputs also serve as defaults to the subsequent `analyze` step, which finalizes the database and executes queries. [#738](https://github.com/github/codeql-action/pull/738)
+- When used with CodeQL 2.7.1 or above, the Action now includes custom query help in the analysis results uploaded to GitHub code scanning, if available. To add help text for a custom query, create a Markdown file next to the `.ql` file containing the query, using the same base name but the file extension `.md`. [#804](https://github.com/github/codeql-action/pull/804)
+
 ## 1.0.21 - 28 Oct 2021
 
 - Update default CodeQL bundle version to 2.7.0. [#795](https://github.com/github/codeql-action/pull/795)
