• 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. 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 !. #4037

• The new address format for the config-file input that was introduced in CodeQL Action 4.37.0 is now enabled by default. In addition to the format described there, the remote= prefix can now be used to explicitly indicate that the input refers to a remote file. All previous input formats continue to be accepted as well. #4023
• The CodeQL Action can now make use of configured private registries in Default Setup to retrieve CodeQL configuration files from remote repositories that require authentication. This will allow customers to store their CodeQL configuration in a single repository that can then be referenced by Default Setup workflows in other repositories. We expect to roll this and other, related changes out to everyone in July. #4007

• In addition to the existing input format, the config-file input for the codeql-action/init step will soon support a new [owner/]repo[@ref][:path] format. All components except the repository name are optional. If omitted, owner defaults to the same owner as the repository the analysis is running for, ref to main, and path to .github/codeql-action.yaml. Support for this format ships in this version of the CodeQL Action, but will only be enabled over the coming weeks. #3973
