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

Some code that compiled successfully with older GCC versions might require
source changes, see http://gcc.gnu.org/gcc-11/porting_to.html for

The release is in the gcc-11.1.0/ subdirectory.

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!
