Version 16.1 of the GNU Compiler Collection (GCC) has been released.

The C++ frontend now defaults to the GNU C++20 dialect and the corresponding parts of the standard library are no longer experimental. Several C++26 features receive experimental support, including Reflection (-freflection), Contracts, expansion statements and std::simd.

Other changes include the introduction of an experimental compiler frontend for the Algol68 language, ability to output GCC diagnostics in HTML form, and more.

Greg Kroah-Hartman has released the 7.0.3, 6.18.26, 6.12.85, 6.6.137, 6.1.170, 5.15.204, and 5.10.254 stable kernels. The 7.0.3 and 6.18.26 kernels only contain fixes needed for Xen users; the others, though, have backported fixes for the recently disclosed AEAD socket vulnerability. Kroah-Hartman advises that all users of the other kernel series must upgrade.
