* The <stdbit.h> header type-generic macros have been changed when using
GCC 14.1 or later to use __builtin_stdc_bit_ceil etc. built-in functions
* The GNU C Library now supports a feature test macro _ISOC23_SOURCE to
enable features from the ISO C23 standard
* The ISO C23 function families introduced in TS
18661-4:2015 are now supported in <math.h>
* A new tunable, glibc.rtld.enable_secure, can be used to run a program
as if it were a setuid process
* On Linux, the epoll header was updated to include epoll ioctl definitions
and the related structure added in Linux kernel 6.9
* The fortify functionality has been significantly enhanced for building
programs with clang against the GNU C Library
* Many functions have been added to the vector library for aarch64
* On x86, memset can now use non-temporal stores to improve the performance
of large writes
* Architectures which use a 32-bit seconds-since-epoch field in struct
lastlog, struct utmp, struct utmpx (such as i386, powerpc64le, rv32,
rv64, x86-64) switched from a signed to an unsigned type for that
field
* __rseq_size now denotes the size of the active rseq area (20 bytes
initially), not the size of struct rseq (32 bytes initially).
