+Version 2.30
+
+Major new features:
+
+* Unicode 12.0.0 Support: Character encoding, character type info, and
+ transliteration tables are all updated to Unicode 12.0.0, using
+ generator scripts contributed by Mike FABIAN (Red Hat).
+
+* The dynamic linker accepts the --preload argument to preload shared
+ objects, in addition to the LD_PRELOAD environment variable.
+
+* On Linux, the gettid function has been added.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The functions clock_gettime, clock_getres, clock_settime,
+ clock_getcpuclockid, clock_nanosleep were removed from the librt library
+ for new applications (on architectures which had them). Instead, the
+ definitions in libc will be used automatically, which have been available
+ since glibc 2.17.
+
+Changes to build and runtime requirements:
+
+* GCC 6.2 or later is required to build the GNU C Library.
+
+ Older GCC versions and non-GNU compilers are still supported when
+ compiling programs that use the GNU C Library.
+
+Security related changes:
+
+ CVE-2019-7309: x86-64 memcmp used signed Jcc instructions to check
+ size. For x86-64, memcmp on an object size larger than SSIZE_MAX
+ has undefined behavior. On x32, the size_t argument may be passed
+ in the lower 32 bits of the 64-bit RDX register with non-zero upper
+ 32 bits. When it happened with the sign bit of RDX register set,
+ memcmp gave the wrong result since it treated the size argument as
+ zero. Reported by H.J. Lu.
+
+The following bugs are resolved with this release:
+
+ [The release manager will add the list generated by
+ scripts/list-fixed-bugs.py just before the release.]

+Version 2.29
+
+Major new features:
+
+* The getcpu wrapper function has been added, which returns the currently
+ used CPU and NUMA node. This function is Linux-specific.
+
+* A new convenience target has been added for distribution maintainers
+ to build and install all locales as directories with files. The new
+ target is run by issuing the following command in your build tree:
+ 'make localedata/install-locale-files', with an optional DESTDIR
+ to set the install root if you wish to install into a non-default
+ configured location.
+
+* Optimized generic exp, exp2, log, log2, pow, sinf, cosf, sincosf and tanf.
+
+* The reallocarray function is now declared under _DEFAULT_SOURCE, not just
+ for _GNU_SOURCE, to match BSD environments.
+
+* For powercp64le ABI, Transactional Lock Elision is now enabled iff kernel
+ indicates that it will abort the transaction prior to entering the kernel
+ (PPC_FEATURE2_HTM_NOSC on hwcap2). On older kernels the transaction is
+ suspended, and this caused some undefined side-effects issues by aborting
+ transactions manually. Glibc avoided it by abort transactions manually on
+ each syscall, but it lead to performance issues on newer kernels where the
+ HTM state is saved and restore lazily (the state being saved even when the
+ process actually does not use HTM).
+
+* The functions posix_spawn_file_actions_addchdir_np and
+ posix_spawn_file_actions_addfchdir_np have been added, enabling
+ posix_spawn and posix_spawnp to run the new process in a different
+ directory. These functions are GNU extensions. The function
+ posix_spawn_file_actions_addchdir_np is similar to the Solaris function
+ of the same name.
+
+* The popen and system do not run atfork handlers anymore (BZ#17490).
+ Although it is a possible POSIX violation, the POSIX rationale in
+ pthread_atfork documentation regarding atfork handlers is to handle
+ inconsistent mutex state after a fork call in a multi-threaded process.
+ In both popen and system there is no direct access to user-defined mutexes.
+
+* Support for the C-SKY ABIV2 running on Linux has been added. This port
+ requires at least binutils-2.32, gcc-9.0, and linux-4.20. Two ABIs are
+ supported:
+ - C-SKY ABIV2 soft-float little-endian
+ - C-SKY ABIV2 hard-float little-endian
+
+* strftime's default formatting of a locale's alternative year (%Ey)
+ has been changed to zero-pad the year to a minimum of two digits,
+ like "%y". This improves the display of Japanese era years during
+ the first nine years of a new era, and is expected to be harmless
+ for all other locales (only Japanese locales regularly have
+ alternative year numbers less than 10). Zero-padding can be
+ overridden with the '_' or '-' flags (which are GNU extensions).
+
+* As a GNU extension, the '_' and '-' flags can now be applied to
+ "%EY" to control how the year number is formatted; they have the
+ same effect that they would on "%Ey".
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The glibc.tune tunable namespace has been renamed to glibc.cpu and the
+ tunable glibc.tune.cpu has been renamed to glibc.cpu.name.
+
+* The type of the pr_uid and pr_gid members of struct elf_prpsinfo, defined
+ in <sys/procfs.h>, has been corrected to match the type actually used by
+ the Linux kernel. This affects the size and layout of that structure on
+ MicroBlaze, MIPS (n64 ABI only), Nios II and RISC-V.
+
+* For the MIPS n32 ABI, the type of the pr_sigpend and pr_sighold members of
+ struct elf_prstatus, and the pr_flag member of struct elf_prpsinfo,
+ defined in <sys/procfs.h>, has been corrected to match the type actually
+ used by the Linux kernel. This affects the size and layout of those
+ structures.
+
+* An archaic GNU extension to scanf, under which '%as', '%aS', and '%a[...]'
+ meant to scan a string and allocate space for it with malloc, is now
+ restricted to programs compiled in C89 or C++98 mode with _GNU_SOURCE
+ defined. This extension conflicts with C99's use of '%a' to scan a
+ hexadecimal floating-point number, which is now available to programs
+ compiled as C99 or C++11 or higher, regardless of _GNU_SOURCE.
+
+ POSIX.1-2008 includes the feature of allocating a buffer for string input
+ with malloc, using the modifier letter 'm' instead. Programs using
+ '%as', '%aS', or '%a[...]' with the old GNU meaning should change to
+ '%ms', '%mS', or '%m[...]' respectively. Programs that wish to use the
+ C99 '%a' no longer need to avoid _GNU_SOURCE.
+
+ GCC's -Wformat warnings can detect most uses of this extension, as long
+ as all functions that call vscanf, vfscanf, or vsscanf are annotated with
+ __attribute__ ((format (scanf, ...))).
+
+Changes to build and runtime requirements:
+
+* Python 3.4 or later is required to build the GNU C Library.
+
+* On most architectures, GCC 5 or later is required to build the GNU C
+ Library. (On powerpc64le, GCC 6.2 or later is still required, as before.)
+
+ Older GCC versions and non-GNU compilers are still supported when
+ compiling programs that use the GNU C Library.
+
+Security related changes:
+
+ CVE-2018-19591: A file descriptor leak in if_nametoindex can lead to a
+ denial of service due to resource exhaustion when processing getaddrinfo
+ calls with crafted host names. Reported by Guido Vranken.
+
+ CVE-2019-6488: On x32, the size_t parameter may be passed in the lower
+ 32 bits of a 64-bit register with with non-zero upper 32 bit. When it
+ happened, accessing the 32-bit size_t value as the full 64-bit register
+ in the assembly string/memory functions would cause a buffer overflow.
+ Reported by H.J. Lu.
+
+ CVE-2016-10739: The getaddrinfo function could successfully parse IPv4
+ addresses with arbitrary trailing characters, potentially leading to data
+ or command injection issues in applications.

Version 2.28
Major new features:
+* The localization data for ISO 14651 is updated to match the 2016
+ Edition 4 release of the standard, this matches data provided by
+ Unicode 9.0.0. This update introduces significant improvements to the
+ collation of Unicode characters. This release deviates slightly from
+ the standard in that the collation element ordering for lowercase and
+ uppercase LATIN script characters is adjusted to ensure that regular
+ expressions with ranges like [a-z] and [A-Z] don't interleave e.g. A
+ is not matched by [a-z]. With the update many locales have been
+ updated to take advantage of the new collation information. The new
+ collation information has increased the size of the compiled locale
+ archive or binary locales.
+
+* The GNU C Library can now be compiled with support for Intel CET, AKA
+ Intel Control-flow Enforcement Technology. When the library is built
+ with --enable-cet, the resulting glibc is protected with indirect
+ branch tracking (IBT) and shadow stack (SHSTK). CET-enabled glibc is
+ compatible with all existing executables and shared libraries. This
+ feature is currently supported on i386, x86_64 and x32 with GCC 8 and
+ binutils 2.29 or later. Note that CET-enabled glibc requires CPUs
+ capable of multi-byte NOPs, like x86-64 processors as well as Intel
+ Pentium Pro or newer. NOTE: --enable-cet has been tested for i686,
+ x86_64 and x32 on non-CET processors. --enable-cet has been tested
+ for x86_64 and x32 on CET SDVs, but Intel CET support hasn't been
+ validated for i686.
+
+* The GNU C Library now has correct support for ABSOLUTE symbols
+ (SHN_ABS-relative symbols). Previously such ABSOLUTE symbols were
+ relocated incorrectly or in some cases discarded. The GNU linker can
+ make use of the newer semantics, but it must communicate it to the
+ dynamic loader by setting the ELF file's identification (EI_ABIVERSION
+ field) to indicate such support is required.
+
* Unicode 11.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 11.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
- fdiv, fdivl, ddivl and corresponding fMdivfN, fMdivfNx, fMxdivfN and
fMxdivfNx functions.
-* Nominative and genitive month names are now supported for the following
- languages: Armenian, Asturian, Catalan, Czech, Kashubian, Scottish Gaelic,
- Upper Sorbian, and Walloon. The following languages now support
- abbreviated alternative month names: Catalan, Greek, and Kashubian.
+* Two grammatical forms of month names are now supported for the following
+ languages: Armenian, Asturian, Catalan, Czech, Kashubian, Occitan, Ossetian,
+ Scottish Gaelic, Upper Sorbian, and Walloon. The following languages now
+ support two grammatical forms in abbreviated month names: Catalan, Greek,
+ and Kashubian.
-* New locale added: Lower Sorbian (dsb_DE), including the support of the
- nominative and genitive month names.
+* Newly added locales: Lower Sorbian (dsb_DE) and Yakut (sah_RU) also
+ include the support for two grammatical forms of month names.
* Building and running on GNU/Hurd systems now works without out-of-tree
patches.
flags and a non-existing destination (and therefore has a race condition
that can clobber the destination inadvertently).
+* The statx function has been added, a variant of the fstatat64
+ function with an additional flags argument. If there is no direct
+ kernel support for statx, glibc provides basic stat support based on
+ the fstatat64 function.
+
* IDN domain names in getaddrinfo and getnameinfo now use the system libidn2
library if installed. libidn2 version 2.0.5 or later is recommended. If
libidn2 is not available, internationalized domain names are not encoded
for safety are now load errors e.g. /foo/${ORIGIN}.so in DT_NEEDED
results in a load failure now.
+* Support for ISO C threads (ISO/IEC 9899:2011) has been added. The
+ implementation includes all the standard functions provided by
+ <threads.h>:
+
+ - thrd_current, thrd_equal, thrd_sleep, thrd_yield, thrd_create,
+ thrd_detach, thrd_exit, and thrd_join for thread management.
+
+ - mtx_init, mtx_lock, mtx_timedlock, mtx_trylock, mtx_unlock, and
+ mtx_destroy for mutual exclusion.
+
+ - call_once for function call synchronization.
+
+ - cnd_broadcast, cnd_destroy, cnd_init, cnd_signal, cnd_timedwait, and
+ cnd_wait for conditional variables.
+
+ - tss_create, tss_delete, tss_get, and tss_set for thread-local storage.
+
+ Application developers must link against libpthread to use ISO C threads.
+
Deprecated and removed features, and other changes affecting compatibility:
* The nonstandard header files <libio.h> and <_G_config.h> are no longer
