CodeQL 2.17.4: Autofixes for Extended queries, faster C++ PR scans

CodeQL is the static analysis engine that powers GitHub code scanning. CodeQL version 2.17.4 has been released and has now been rolled out to code scanning users on GitHub.com.

This changelog combines significant updates from the release of CodeQL 2.17.2,2.17.3, and 2.17.4:

For a full list of changes, please refer to the complete changelog for versions 2.17.2, 2.17.3, and 2.17.4. All new functionality will also be included in GHES 3.14. Users of GHES 3.13 or older can upgrade their CodeQL version.

For security and convenience, we’ve updated how the account picker can be triggered during sign-in to an OAuth or GitHub Application. Some apps will see it all of the time, while all apps are able to trigger it manually.

Native apps (an app with a callback URI that doesn’t lead to an https:// destination) will now always receive the account picker to ensure that users get an opportunity to verify the application and change accounts if need be.

We’ve also added support for the standard prompt parameter with the select_account argument, which an app can provide during the OAuth authorization request to /authorize. This parameter forces the account picker to appear during authentication, interrupting what can otherwise be an instant authentication flow. We recommend using this parameter to better support multiple accounts at once in your app, if a user indicates they want to use another account in your app.

To force the account picker, append the following alongside your client ID and redirect URI parameters when you send the user to GitHub to sign in: &prompt=select_account.

As before, users with multiple signed in accounts will always see the account picker on each authentication.

Configurations are collections of security settings that organization administrators and security managers can define to help roll out GitHub security products at scale.

Starting today, you can enforce configurations. This new feature allows you to prevent users at the repository level from changing the security features that have been enabled and disabled in the configuration attached to their repository.

You can mark a configuration as enforced or unenforced at the bottom of the configurations edit page under the policy section:
Configuration Enforcement

Security configurations are currently available in public beta on GitHub.com and will be available in GitHub Enterprise Server 3.15. You can learn more about security configurations or send us your feedback.
