The GCC developers are proud to announce another major GCC release, 11.1. This release switches the default debugging format to DWARF 5 [1] on most targets and switches the default C++ language version to -std=gnu++17. It makes great progress in the C++20 language support, both on the compiler and library sides [2], adds experimental C++23 support, some C2X enhancements, various optimization enhancements and bug fixes, several new hardware enablement changes and enhancements to the compiler back-ends and many other changes.
Some code that compiled successfully with older GCC versions might require source changes, see http://gcc.gnu.org/gcc-11/porting_to.html for details. See https://gcc.gnu.org/gcc-11/changes.html for more information about changes in GCC 11.1. This release is available from the WWW and FTP servers listed here: https://sourceware.org/pub/gcc/releases/gcc-11.1.0/ https://gcc.gnu.org/mirrors.html The release is in the gcc-11.1.0/ subdirectory. If you encounter difficulties using GCC 11.1, please do not contact me directly. Instead, please visit http://gcc.gnu.org for information about getting help. Driving a leading free software project such as GCC would not be possible without support from its many contributors. Not only its developers, but especially its regular testers and users which contribute to its high quality. The list of individuals is too large to thank individually! ---- [1] See http://dwarfstd.org/Dwarf5Std.php [2] See https://gcc.gnu.org/projects/cxx-status.html, and https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2020
