Version
13.1 of the GCC compiler suite has been released.

This release integrates a frontend for the Modula-2 language which
was previously available separately and lays foundation for a
frontend for the Rust language which will be available in a future
release.

Other changes include the removal of support for the STABS
debugging-information format, addition of a number of C++23 features, a
number of static-analyzer improvements, support for a number of recent CPU
features, and more. See this page for details.
