- Update to glibc 2.32
* Unicode 13.0.0 Support
* New locale added: ckb_IQ
* The GNU C Library now loads audit modules listed in the DT_AUDIT and
DT_DEPAUDIT dynamic section entries of the main executable
* powerpc64le supports IEEE128 long double libm/libc redirects when
using the -mabi=ieeelongdouble to compile C code on supported GCC
toolchains
* To help detect buffer overflows and other out-of-bounds accesses
several APIs have been annotated with GCC 'access' attribute
* On Linux, functions the pthread_attr_setsigmask_np and
pthread_attr_getsigmask_np have been added
* The GNU C Library now provides the header file <sys/single_threaded.h>
which declares the variable __libc_single_threaded
* The functions sigabbrev_np and sigdescr_np have been added
* The functions strerrorname_np and strerrordesc_np have been added
* AArch64 now supports standard branch protection security hardening
in glibc when it is built with a GCC that is configured with
--enable-standard-branch-protection (or if -mbranch-protection=standard
flag is passed when building both GCC target libraries and glibc,
in either case a custom GCC is needed)
* The deprecated <sys/sysctl.h> header and the sysctl function have been
removed
* The sstk function is no longer available to newly linked binaries
* The legacy signal handling functions siginterrupt, sigpause, sighold,
sigrelse, sigignore and sigset, and the sigmask macro have been
deprecated
* ldconfig now defaults to the new format for ld.so.cache
* The deprecated arrays sys_siglist, _sys_siglist, and sys_sigabbrev
are no longer available to newly linked binaries, and their declarations

- Update to glibc 2.27
* Optimized x86-64 asin, atan2, exp, expf, log, pow, atan, sin, cosf,
sinf, sincosf and tan with FMA
* Optimized x86-64 trunc and truncf for processors with SSE4.1
* Optimized generic expf, exp2f, logf, log2f, powf, sinf, cosf and
sincosf
* In order to support faster and safer process termination the malloc API
family of functions will no longer print a failure address and stack
backtrace after detecting heap corruption
* The abort function terminates the process immediately, without flushing
stdio streams
* On platforms where long double has the IEEE binary128 format (aarch64,
alpha, mips64, riscv, s390 and sparc), the math library now implements
_Float128 interfaces for that type, as defined by ISO/IEC TS 18661-3:2015
These are the same interfaces added in version 2.26 for some platforms where
this format is supported but is not the format of long double
* On platforms with support for _Float64x (aarch64, alpha, i386, ia64,
mips64, powerpc64le, riscv, s390, sparc and x86_64), the math library now
implements interfaces for that type, as defined by ISO/IEC TS
18661-3:2015
* The math library now implements interfaces for the _Float32, _Float64 and
_Float32x types, as defined by ISO/IEC TS 18661-3:2015
* glibc now implements the memfd_create and mlock2 functions on Linux
* Support for memory protection keys was added
* The copy_file_range function was added
* The ldconfig utility now processes `include' directives using the C/POSIX
collation ordering
* Support for two grammatical forms of month names has been added
* Support for the RISC-V ISA running on Linux has been added
* Statically compiled applications attempting to load locales compiled for the

- Update to glibc 2.17.90 85891acadf1b:
* CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
has been fixed by disabling the use of pt_chown (Bugzilla #15755).
Distributions can re-enable building and using pt_chown via the new configure
option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
considerable security risks and should only be used if the distribution
understands and accepts the risks.
* CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
#15078).
* CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
fixed (Bugzilla #15330).
* Add support for calling C++11 thread_local object destructors on thread
and program exit. This needs compiler support for offloading C++11
destructor calls to glibc.
* Improved worst case performance of libm functions with double inputs and
output.
* Support for priority inherited mutexes in pthread condition variables on
non-x86 architectures.
* Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
* Optimized string functions for ARM. Implemented by Will Newton and
Richard Henderson.
* Added a benchmark framework to track performance of functions in glibc.
* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
It is based on draft TS 18661 and currently enabled as a GNU extension.
* On Linux, the clock function now uses the clock_gettime system call
for improved precision, rather than old times system call.
* Added new API functions pthread_getattr_default_np and
pthread_setattr_default_np to get and set the default pthread
attributes of a process.
* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
