This security issue did not affect older MPS releases, so no action is required if you use them.

Please pay special attention to the “What is required of you” section of the security blog post and carefully revoke your GitHub tokens.

Standalone IDEs

We highly recommend that standalone MPS-based IDE creators rebuild and redistribute any custom IDEs that are bundled with the GitHub plugin since the old version of the plugin has been disabled.

We also urge all end users of standalone IDEs to update their IDEs, follow the security measures mentioned in the “What is required of you” section of the security blog post, and revoke their GitHub tokens.

On top of this critical security fix, each version comes with its own set of fixed issues:
