The GNU Compiler Collection (GCC) 16 has today transitioned to Stage 4 development. This final stage focuses exclusively on documentation and regression fixing as the compiler nears its stable release. GCC 16 is anticipated to be released in the typical March to April timeframe this year. Key features integrated into GCC 16 include an Algol 68 frontend, support for AMD Zen 6 architecture, and setting C++20 as the default C++ standard. This move marks a significant step towards the official availability of the next major GCC version, bringing new language support and hardware optimizations to developers.
