to a mising GNU_STACK ELF header or explicit explicitly because of the
executable bit in GNU_STACK. The default is to allow executable stacks.
+* Support for the extensible rseq ABI introduced in the Linux kernel version
+ 6.3 has been added. The size and alignment of the rseq area is now
+ determined by auxiliary vector entries when provided by the running kernel.
+ While there are no user visible changes yet, this will allow accessing rseq
+ features past the original 32 bytes ABI once they are introduced in future
+ Linux kernels.
+
Deprecated and removed features, and other changes affecting compatibility:
* The big-endian ARC port (arceb-linux-gnu) has been removed.
