+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 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.
+
+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.
+
+* 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.
+
+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.
+
+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.]
+
+\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:
+ '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.

+
+\f
+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).
+
+* <math.h> functions that round their results to a narrower type are added
+ from TS 18661-1:2014 and TS 18661-3:2015:
+
+ - fadd, faddl, daddl and corresponding fMaddfN, fMaddfNx, fMxaddfN and
+ fMxaddfNx functions.
+
+ - fsub, fsubl, dsubl and corresponding fMsubfN, fMsubfNx, fMxsubfN and
+ fMxsubfNx functions.
+
+ - fmul, fmull, dmull and corresponding fMmulfN, fMmulfNx, fMxmulfN and
+ fMxmulfNx functions.
+
+ - fdiv, fdivl, ddivl and corresponding fMdivfN, fMdivfNx, fMxdivfN and
+ fMxdivfNx functions.
+
+* 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.
+
+* 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.
+
+* The renameat2 function has been added, a variant of the renameat function
+ which has a flags argument. If the flags are zero, the renameat2 function
+ acts like renameat. If the flag is not zero and there is no kernel
+ support for renameat2, the function will fail with an errno value of
+ EINVAL. This is different from the existing gnulib function renameatu,
+ which performs a plain rename operation in case of a RENAME_NOREPLACE
+ 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
+ or decoded even if the AI_IDN or NI_IDN flags are passed to getaddrinfo or
+ getnameinfo. (getaddrinfo calls with non-ASCII names and AI_IDN will fail
+ with an encoding error.) Flags which used to change the IDN encoding and
+ decoding behavior (AI_IDN_ALLOW_UNASSIGNED, AI_IDN_USE_STD3_ASCII_RULES,
+ NI_IDN_ALLOW_UNASSIGNED, NI_IDN_USE_STD3_ASCII_RULES) have been
+ deprecated. They no longer have any effect.
+
+* Parsing of dynamic string tokens in DT_RPATH, DT_RUNPATH, DT_NEEDED,
+ DT_AUXILIARY, and DT_FILTER has been expanded to support the full
+ range of ELF gABI expressions including such constructs as
+ '$ORIGIN$ORIGIN' (if valid). For SUID/GUID applications the rules
+ have been further restricted, and where in the past a dynamic string
+ token sequence may have been interpreted as a literal string it will
+ now cause a load failure. These load failures were always considered
+ unspecified behaviour from the perspective of the dynamic loader, and
+ 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
+ installed. Software that was using either header should be updated to
+ use standard <stdio.h> interfaces instead.
+
+* The stdio functions 'getc' and 'putc' are no longer defined as macros.
+ This was never required by the C standard, and the macros just expanded
+ to call alternative names for the same functions. If you hoped getc and
+ putc would provide performance improvements over fgetc and fputc, instead
+ investigate using (f)getc_unlocked and (f)putc_unlocked, and, if
+ necessary, flockfile and funlockfile.
+
+* All stdio functions now treat end-of-file as a sticky condition. If you
+ read from a file until EOF, and then the file is enlarged by another
+ process, you must call clearerr or another function with the same effect
+ (e.g. fseek, rewind) before you can read the additional data. This
+ corrects a longstanding C99 conformance bug. It is most likely to affect
+ programs that use stdio to read interactive input from a terminal.
+ (Bug #1190.)
+
+* The macros 'major', 'minor', and 'makedev' are now only available from
+ the header <sys/sysmacros.h>; not from <sys/types.h> or various other
+ headers that happen to include <sys/types.h>. These macros are rarely
+ used, not part of POSIX nor XSI, and their names frequently collide with
+ user code; see https://sourceware.org/bugzilla/show_bug.cgi?id=19239 for
+ further explanation.
+
+ <sys/sysmacros.h> is a GNU extension. Portable programs that require
+ these macros should first include <sys/types.h>, and then include
+ <sys/sysmacros.h> if __GNU_LIBRARY__ is defined.
+
+* The tilegx*-*-linux-gnu configurations are no longer supported.
+
+* The obsolete function ustat is no longer available to newly linked
+ binaries; the headers <ustat.h> and <sys/ustat.h> have been removed. This
+ function has been deprecated in favor of fstatfs and statfs.
+
+* The obsolete function nfsservctl is no longer available to newly linked
+ binaries. This function was specific to systems using the Linux kernel
+ and could not usefully be used with the GNU C Library on systems with
+ version 3.1 or later of the Linux kernel.
+
+* The obsolete function name llseek is no longer available to newly linked
+ binaries. This function was specific to systems using the Linux kernel
+ and was not declared in a header. Programs should use the lseek64 name
+ for this function instead.
+
+* The AI_IDN_ALLOW_UNASSIGNED and NI_IDN_ALLOW_UNASSIGNED flags for the
+ getaddrinfo and getnameinfo functions have been deprecated. The behavior
+ previously selected by them is now always enabled.
+
+* The AI_IDN_USE_STD3_ASCII_RULES and NI_IDN_USE_STD3_ASCII_RULES flags for
+ the getaddrinfo and getnameinfo functions have been deprecated. The STD3
+ restriction (rejecting '_' in host names, among other things) has been
+ removed, for increased compatibility with non-IDN name resolution.
+
+* The fcntl function now have a Long File Support variant named fcntl64. It
+ is added to fix some Linux Open File Description (OFD) locks usage on non
+ LFS mode. As for others *64 functions, fcntl64 semantics are analogous with
+ fcntl and LFS support is handled transparently. Also for Linux, the OFD
+ locks act as a cancellation entrypoint.
+
+* The obsolete functions encrypt, encrypt_r, setkey, setkey_r, cbc_crypt,
+ ecb_crypt, and des_setparity are no longer available to newly linked
+ binaries, and the headers <rpc/des_crypt.h> and <rpc/rpc_des.h> are no
+ longer installed. These functions encrypted and decrypted data with the
+ DES block cipher, which is no longer considered secure. Software that
+ still uses these functions should switch to a modern cryptography library,
+ such as libgcrypt.
+
+* Reflecting the removal of the encrypt and setkey functions above, the
+ macro _XOPEN_CRYPT is no longer defined. As a consequence, the crypt
+ function is no longer declared unless _DEFAULT_SOURCE or _GNU_SOURCE is
+ enabled.
+
+* The obsolete function fcrypt is no longer available to newly linked
+ binaries. It was just another name for the standard function crypt,
+ and it has not appeared in any header file in many years.
+
+* We have tentative plans to hand off maintenance of the passphrase-hashing
+ library, libcrypt, to a separate development project that will, we hope,
+ keep up better with new passphrase-hashing algorithms. We will continue
+ to declare 'crypt' in <unistd.h>, and programs that use 'crypt' or
+ 'crypt_r' should not need to change at all; however, distributions will
+ need to install <crypt.h> and libcrypt from a separate project.
+
+ In this release, if the configure option --disable-crypt is used, glibc
+ will not install <crypt.h> or libcrypt, making room for the separate
+ project's versions of these files. The plan is to make this the default
+ behavior in a future release.
+
+Changes to build and runtime requirements:
+
+ GNU make 4.0 or later is now required to build glibc.
+
+Security related changes:
+
+ CVE-2016-6261, CVE-2016-6263, CVE-2017-14062: Various vulnerabilities have
+ been fixed by removing the glibc-internal IDNA implementation and using
+ the system-provided libidn2 library instead. Originally reported by Hanno
+ Böck and Christian Weisgerber.
+
+ CVE-2017-18269: An SSE2-based memmove implementation for the i386
+ architecture could corrupt memory. Reported by Max Horn.
+
+ CVE-2018-11236: Very long pathname arguments to realpath function could
+ result in an integer overflow and buffer overflow. Reported by Alexey
+ Izbyshev.
