This release brings support for various C++23 constructs like `if consteval` and multidimensional subscript operators. Vectorization is now enabled for O2 too, and `-ftrivial-auto-var-init` has been added which can help us find and prevent security issues coming from uninitialized variables. Toolchain/Patches/gcc.patch is now significanly smaller as some unused, autoconf-generated code has been removed.
