Major new features:
* The following ISO C23 function families (introduced in TS
18661-4:2015) are now supported in <math.h>. Each family includes
functions for float, double, long double, _FloatN and _FloatNx, and a
type-generic macro in <tgmath.h>.
- Power and absolute-value functions: compoundn, pown, powr, rootn,
rsqrt.
* On Linux, the pthread_gettid_np function has been added.
* The ISO C2Y family of unsigned abs functions, i.e. uabs, ulabs,
ullabs, and uimaxabs, is now supported.
* On Linux, the <termios.h> interface now supports arbitrary baud rates;
speed_t is redefined to simply be the baud rate specified as an
unsigned int, which matches the kernel interface.
* The thread-local cache in malloc (tcache) now supports caching of
large blocks. This feature can be enabled by setting the tunable
glibc.malloc.tcache_max to a larger value (max 4194304). Tcache is
also significantly faster for small sizes.
* A new configure option, "--enable-sframe", can be used to enable
SFrame support of the GNU C Libraries. SFrame is a new stack trace
information format which can be used by backtrace. It requires
binutils with a minimum version of 2.45.
* Support for lightweight stack guard pages via madvise and the
MADV_GUARD_INSTALL flag has been added to pthread_create.
* Additional optimized and correctly rounded mathematical functions have
been imported from the CORE-MATH project, in particular acospif,
asinpif, atanpif, atan2pif, cospif, sinpif, tanpif.
* The testsuite has been significantly extended, including coverage of
the functionality of the printf and scanf function families in many
variants.
* The manual has been significantly extended and updated, particularly
the threads, terminal, filesystem, resource, and math chapters.
* Code has been added to detect the x86-64 Intel Arrow Lake, Panther
Lake, Clearwater Forest, and Diamond Rapids microarchitectures.
* Regarding S390, support for the new z17 platform has been added.
Deprecated and removed features, and other changes affecting compatibility:
* The glibc.rtld.execstack tunable now supports a compatibility mode to
allow programs that require an executable stack through dynamically
loaded shared libraries.
* On Linux, the <termio.h> header and the definition of struct termio
in <sys/ioctl.h> have been removed. The termio interface has been
obsolete since the very first version of POSIX.1 in 1988, replaced
with <termios.h>.
* The support for TX lock elision of pthread mutexes has been deprecated
on all architectures and will be removed in the next release.
* On AArch64 Linux targets supporting the Scalable Matrix Extension
(SME), setjmp and sigsetjmp will disable the ZA state of SME.
Changes to build and runtime requirements:
* GCC 12.1 or later is now required to build the GNU C Library.
* GNU Binutils 2.39 or later is now required to build the GNU C Library.
