+Version 2.31
+
+Major new features:
+
+* The GNU C Library now supports a feature test macro _ISOC2X_SOURCE to
+ enable features from the draft ISO C2X standard. Only some features from
+ this draft standard are supported by the GNU C Library, and as the draft
+ is under active development, the set of features enabled by this macro is
+ liable to change. Features from C2X are also enabled by _GNU_SOURCE, or
+ by compiling with "gcc -std=gnu2x".
+
+* The <math.h> functions that round their results to a narrower type now
+ have corresponding type-generic macros in <tgmath.h>, as defined in TS
+ 18661-1:2014 and TS 18661-3:2015 as amended by the resolution of
+ Clarification Request 13 to TS 18661-3.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The totalorder and totalordermag functions, and the corresponding
+ functions for other floating-point types, now take pointer arguments to
+ avoid signaling NaNs possibly being converted to quiet NaNs in argument
+ passing. This is in accordance with the resolution of Clarification
+ Request 25 to TS 18661-1, as applied for C2X. Existing binaries that pass
+ floating-point arguments directly will continue to work.

+Version 2.30
+
+Major new features:
+
+* Unicode 12.1.0 Support: Character encoding, character type info, and
+ transliteration tables are all updated to Unicode 12.1.0, 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.
+
+* The twalk_r function has been added. It is similar to the existing
+ twalk function, but it passes an additional caller-supplied argument
+ to the callback function.
+
+* On Linux, the getdents64, gettid, and tgkill functions have been added.
+
+* Minguo (Republic of China) calendar support has been added as an
+ alternative calendar for the following locales: zh_TW, cmn_TW, hak_TW,
+ nan_TW, lzh_TW.
+
+* The entry for the new Japanese era has been added for ja_JP locale.
+
+* Memory allocation functions malloc, calloc, realloc, reallocarray, valloc,
+ pvalloc, memalign, and posix_memalign fail now with total object size
+ larger than PTRDIFF_MAX. This is to avoid potential undefined behavior with
+ pointer subtraction within the allocated object, where results might
+ overflow the ptrdiff_t type.
+
+* The dynamic linker no longer refuses to load objects which reference
+ versioned symbols whose implementation has moved to a different soname
+ since the object has been linked. The old error message, symbol
+ FUNCTION-NAME, version SYMBOL-VERSION not defined in file DSO-NAME with
+ link time reference, is gone.
+
+* Add new POSIX-proposed pthread_cond_clockwait, pthread_mutex_clocklock,
+ pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock and sem_clockwait
+ functions. These behave similarly to their "timed" equivalents, but also
+ accept a clockid_t parameter to determine which clock their timeout should
+ be measured against. All functions allow waiting against CLOCK_MONOTONIC
+ and CLOCK_REALTIME. The decision of which clock to be used is made at the
+ time of the wait (unlike with pthread_condattr_setclock, which requires
+ the clock choice at initialization time).
+
+* On AArch64 the GNU IFUNC resolver call ABI changed: old resolvers still
+ work, new resolvers can use a second argument which can be extended in
+ the future, currently it contains the AT_HWCAP2 value.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The copy_file_range function fails with ENOSYS if the kernel does not
+ support the system call of the same name. Previously, user space
+ emulation was performed, but its behavior did not match the kernel
+ behavior, which was deemed too confusing. Applications which use the
+ copy_file_range function can no longer rely on glibc to provide a fallback
+ on kernels that do not support the copy_file_range system call, and if
+ this function returns ENOSYS, they will need to use their own fallback.
+ Support for copy_file_range for most architectures was added in version
+ 4.5 of the mainline Linux kernel.
+
+* 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.
+
+* The obsolete and never-implemented XSI STREAMS header files <stropts.h>
+ and <sys/stropts.h> have been removed.
+
+* Support for the "inet6" option in /etc/resolv.conf and the RES_USE_INET6
+ resolver flag (deprecated in glibc 2.25) have been removed.
+
+* The obsolete RES_INSECURE1 and RES_INSECURE2 option flags for the DNS stub
+ resolver have been removed from <resolv.h>.
+
+* With --enable-bind-now, installed programs are now linked with the
+ BIND_NOW flag.
+
+* Support for the PowerPC SPE ISA extension (powerpc-*-*gnuspe*
+ configurations) has been removed, following the deprecation of this
+ subarchitecture in version 8 of GCC, and its removal in version 9.
+
+* On 32-bit Arm, support for the port-based I/O emulation and the <sys/io.h>
+ header have been removed.
+
+* The Linux-specific <sys/sysctl.h> header and the sysctl function have been
+ deprecated and will be removed from a future version of glibc.
+ Application should directly access /proc instead. For obtaining random
+ bits, the getentropy function can be used.
+
+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.
+
+ CVE-2019-9169: Attempted case-insensitive regular-expression match
+ via proceed_next_node in posix/regexec.c leads to heap-based buffer
+ over-read. Reported by Hongxu Chen.

\f
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:
to set the install root if you wish to install into a non-default
configured location.
-* Optimized generic exp, exp2, log, sinf, cosf, sincosf and tanf.
+* 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:
- [Add changes to build and runtime requirements here]
+* 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:
- [Add security related changes here]
+ 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.
