+Version 2.40
+
+Major new features:
+
+* The <stdbit.h> header type-generic macros have been changed when using
+ GCC 14.1 or later to use __builtin_stdc_bit_ceil etc. built-in functions
+ in order to support unsigned __int128 and/or unsigned _BitInt(N) operands
+ with arbitrary precisions when supported by the target.
+
+* The GNU C Library now supports a feature test macro _ISOC23_SOURCE to
+ enable features from the ISO C23 standard. Only some features from
+ this standard are supported by the GNU C Library. The older name
+ _ISOC2X_SOURCE is still supported. Features from C23 are also enabled
+ by _GNU_SOURCE, or by compiling with the GCC options -std=c23,
+ -std=gnu23, -std=c2x or -std=gnu2x.
+
+* A new tunable, glibc.rtld.enable_secure, used to run a program
+ as if it were a setuid process. This is currently a testing tool to allow
+ more extensive verification tests for AT_SECURE programs and not meant to
+ be a security feature.

+\f
+Version 2.39
+
+Major new features:
+
+* A new tunable, glibc.cpu.plt_rewrite, can be used to enable PLT
+ rewrite on x86-64. When enabled with non-lazy binding, the dynamic
+ linker will rewrite indirect branches in PLT with direct branches.
+
+* Sync with Linux kernel 6.6 shadow stack interface. The --enable-cet
+ configure option is only supported on x86-64.
+
+* struct statvfs now has an f_type member, equal to the f_type statfs member;
+ on the Hurd this was always available under a reserved name,
+ and under Linux a spare has been allocated: it was always zero
+ in previous versions of glibc, and zero is not a valid result.
+
+* On Linux, the functions posix_spawnattr_getcgroup_np and
+ posix_spawnattr_setcgroup_np have been added, along with the
+ POSIX_SPAWN_SETCGROUP flag. They allow posix_spawn and posix_spawnp
+ to set the cgroupv2 in the new process in a race-free manner. These
+ functions are GNU extensions and require a kernel with clone3 support.
+
+* On Linux, the pidfd_spawn and pidfd_spawp functions have been added.
+ They have a similar prototype and semantic as posix_spawn, but instead of
+ returning a process ID, they return a file descriptor that can be used
+ along other pidfd functions (like pidfd_send_signal, poll, or waitid).
+ The pidfd functionality avoids the issue of PID reuse with the traditional
+ posix_spawn interface.
+
+* On Linux, the pidfd_getpid function has been added. It allows retrieving
+ the process ID associated with the process file descriptor created by
+ pid_spawn, fork_np, or pidfd_open.
+
+* scanf-family functions now support the wN format length modifiers for
+ arguments pointing to types intN_t, int_leastN_t, uintN_t or
+ uint_leastN_t (for example, %w32d to read int32_t or int_least32_t in
+ decimal, or %w32x to read uint32_t or uint_least32_t in hexadecimal)
+ and the wfN format length modifiers for arguments pointing to types
+ int_fastN_t or uint_fastN_t, as specified in draft ISO C2X.
+
+* A new tunable, glibc.mem.decorate_maps, can be used to add additional
+ information on underlying memory allocated by the glibc (for instance,
+ on thread stack created by pthread_create or memory allocated by
+ malloc).
+
+* The <stdbit.h> header has been added from ISO C2X, with
+ stdc_leading_zeros, stdc_leading_ones, stdc_trailing_zeros,
+ stdc_trailing_ones, stdc_first_leading_zero, stdc_first_leading_one,
+ stdc_first_trailing_zero, stdc_first_trailing_one, stdc_count_zeros,
+ stdc_count_ones, stdc_has_single_bit, stdc_bit_width, stdc_bit_floor
+ and stdc_bit_ceil function families, each having functions for
+ unsigned char, unsigned short, unsigned int, unsigned long int and
+ unsigned long long int, and a type-generic macro.
+
+* On AArch64 new symbols were added to libmvec and now math.h has
+ annotations to allow GCC 9 or newer to auto-vectorize calls to the
+ following scalar math functions when -ffast-math is specified:
+ acos, acosf, asin, asinf, atan, atanf, atan2, atan2f, cos, cosf,
+ exp, expf, exp10, exp10f, exp2, exp2f, expm1, expm1f, log, logf,
+ log10, log10f, log1p, log1pf, log2, log2f, sin, sinf, tan, tanf.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The ldconfig program now skips file names containing ';' or ending in
+ ".dpkg.tmp" or ".dpkg.new", to avoid examining temporary files created
+ by the RPM and dpkg package managers.
+
+* libcrypt has been removed from the GNU C Library. The configure
+ options "--enable-crypt" and "--enable-nss-crypt" are no longer
+ available. <crypt.h>, libcrypt.a, and libcrypt.so.1 will not be
+ installed. For now <unistd.h> continues to declare the crypt
+ function by default, to avoid introducing vulnerabilities into
+ existing applications due to a missing prototype. This declaration
+ is deprecated and may be removed in a future glibc release.
+
+ The replacement for libcrypt is libxcrypt, maintained separately from
+ GNU libc, but available under compatible licensing terms, and providing
+ binary backward compatibility with the former libcrypt. It is currently
+ distributed from <https://github.com/besser82/libxcrypt/>.
+
+ As a consequence of this removal, GNU libc no longer makes any use of
+ the NSS cryptography library (Network Security Services; not to be
+ confused with Name Service Switch). Distributors of binary packages
+ of GNU libc are advised to check whether their build processes can be
+ simplified.
+
+* The dynamic linker calls the malloc and free functions in more cases
+ during TLS access if a shared object with dynamic TLS is loaded and
+ unloaded. This can result in an infinite recursion if a malloc
+ replacement library or its dependencies use dynamic TLS instead of
+ initial-exec TLS.
+
+* The ia64*-*-linux-gnu configurations are no longer supported.
+
+Changes to build and runtime requirements:
+
+* Building on LoongArch requires at a minimum binutils 2.41 for vector
+ instructions.

+\f
+Version 2.38
+
+Major new features:
+
+* When C2X features are enabled and the base argument is 0 or 2, the
+ following functions support binary integers prefixed by 0b or 0B as
+ input: strtol, strtoll, strtoul, strtoull, strtol_l, strtoll_l,
+ strtoul_l, strtoull_l, strtoimax, strtoumax, strtoq, strtouq, wcstol,
+ wcstoll, wcstoul, wcstoull, wcstol_l, wcstoll_l, wcstoul_l,
+ wcstoull_l, wcstoimax, wcstoumax, wcstoq, wcstouq. Similarly, the
+ following functions support binary integers prefixed by 0b or 0B as
+ input to the %i format: fscanf, scanf, sscanf, vscanf, vsscanf,
+ vfscanf, fwscanf, wscanf, swscanf, vfwscanf, vwscanf, vswscanf; those
+ functions also support the %b format for binary integers, with or
+ without such a prefix and independent of standards mode.
+
+* PRIb*, PRIB* and SCNb* macros from C2X have been added to
+ <inttypes.h>.
+
+* printf-family functions now support the wN format length modifiers for
+ arguments of type intN_t, int_leastN_t, uintN_t or uint_leastN_t (for
+ example, %w32d to print int32_t or int_least32_t in decimal, or %w32x
+ to print uint32_t or uint_least32_t in hexadecimal) and the wfN format
+ length modifiers for arguments of type int_fastN_t or uint_fastN_t, as
+ specified in draft ISO C2X.
+
+* A new tunable, glibc.pthread.stack_hugetlb, can be used to disable
+ Transparent Huge Pages (THP) in stack allocation at pthread_create.
+
+* Support for x86_64 running on Hurd has been added. This port requires
+ as least binutils 2.40 and GCC 13:
+
+ - x86_64-gnu
+
+* Vector math library libmvec support has been added to AArch64. It
+ requires GCC version >= 10.1.0. It can be disabled via
+ "--disable-mathvec", however that is not a supported configuration as
+ it changes the ABI. The symbol names follow the AArch64 vector ABI,
+ they are declared in math.h and have to be called manually at this point.
+
+* The strlcpy and strlcat functions have been added. They are derived
+ from OpenBSD, and are expected to be added to a future POSIX version.
+
+* A new configure option, "--enable-fortify-source", can be used to build the
+ GNU C Library with _FORTIFY_SOURCE. The level of fortification can either be
+ provided, or is set to the highest value supported by the compiler. If not
+ explicitly enabled, then fortify source is forcibly disabled so to keep
+ original behavior unchanged.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* libcrypt is no longer built by default; one may use the "--enable-crypt"
+ option to build libcrypt. libcrypt is likely to be removed from the
+ GNU C Library in a future release, so it is recommended that
+ applications port away from it to an alternative such as libxcrypt.
+
+* In the Linux kernel for the hppa/parisc architecture some of the
+ MADV_XXX constants were changed to have the same values as the other
+ architectures. New programs compiled with this glibc version and which
+ use the madvise call will require at least Linux kernel version 6.2,
+ alternatively stable kernels from versions 6.1.6, 5.15.87, 5.10.163,
+ 5.4.228, 4.19.270 or 4.14.303.
+
+* The "--disable-experimental-malloc" option is no longer available. The
+ per-thread cache can still be disabled per-application using tunables
+ (glibc.malloc.tcache_count set to zero).
+
+* The configure option "--enable-tunables" has been removed. The tunable
+ feature is now always enabled.
+
+Changes to build and runtime requirements:
+
+* Building libmvec on AArch64 requires at a minimum GCC 10.1.0 for SVE
+ ACLE.
+
+Security related changes:
+
+ CVE-2023-25139: When the printf family of functions is called with a
+ format specifier that uses an <apostrophe> (enable grouping) and a
+ minimum width specifier, the resulting output could be larger than
+ reasonably expected by a caller that computed a tight bound on the
+ buffer size. The resulting larger than expected output could result
+ in a buffer overflow in the printf family of functions.
+
+The following bugs are resolved with this release:
+
+ [178] string: Please add strlcpy and strlcat (attached)
+ [14697] nptl: Behavior of exit is nonconformant with respect to
+ threads and stdio

+ [30662] nscd: Group and password cache use errno in place of errval
+\f
+Version 2.37
+
+Major new features:
+
+* The getent tool now supports the --no-addrconfig option. The output of
+ getent with --no-addrconfig may contain addresses of families not
+ configured on the current host i.e. as-if you had not passed
+ AI_ADDRCONFIG to getaddrinfo calls.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The dynamic linker no longer loads shared objects from the "tls"
+ subdirectories on the library search path or the subdirectory that
+ corresponds to the AT_PLATFORM system name, or employs the legacy AT_HWCAP
+ search mechanism, which was deprecated in version 2.33.
+
+Security related changes:
+
+ CVE-2022-39046: When the syslog function is passed a crafted input
+ string larger than 1024 bytes, it reads uninitialized memory from the
+ heap and prints it to the target log file, potentially revealing a
+ portion of the contents of the heap.

+Version 2.36
+
+Major new features:
+
+* Support for DT_RELR relative relocation format has been added to
+ glibc. This is a new ELF dynamic tag that improves the size of
+ relative relocations in shared object files and position independent
+ executables (PIE). DT_RELR generation requires linker support for
+ -z pack-relative-relocs option, which is supported for some targets
+ in recent binutils versions. Lazy binding doesn't apply to DT_RELR.
+
+* On Linux, the pidfd_open, pidfd_getfd, and pidfd_send_signal functions
+ have been added. The pidfd functionality provides access to a process
+ while avoiding the issue of PID reuse on traditional Unix systems.
+
+* On Linux, the process_madvise function has been added. It has the
+ same functionality as madvise but alters the target process identified
+ by the pidfd.
+
+* On Linux, the process_mrelease function has been added. It allows a
+ caller to release the memory of a dying process. The release of the
+ memory is carried out in the context of the caller, using the caller's
+ CPU affinity, and priority with CPU usage accounted to the caller.
+
+* The “no-aaaa” DNS stub resolver option has been added. System
+ administrators can use it to suppress AAAA queries made by the stub
+ resolver, including AAAA lookups triggered by NSS-based interfaces
+ such as getaddrinfo. Only DNS lookups are affected: IPv6 data in
+ /etc/hosts is still used, getaddrinfo with AI_PASSIVE will still
+ produce IPv6 addresses, and configured IPv6 name servers are still
+ used. To produce correct Name Error (NXDOMAIN) results, AAAA queries
+ are translated to A queries. The new resolver option is intended
+ primarily for diagnostic purposes, to rule out that AAAA DNS queries
+ have adverse impact. It is incompatible with EDNS0 usage and DNSSEC
+ validation by applications.
+
+* On Linux, the fsopen, fsmount, move_mount, fsconfig, fspick, open_tree,
+ and mount_setattr have been added. They are part of the new Linux kernel
+ mount APIs that allow applications to more flexibly configure and operate
+ on filesystem mounts. The new mount APIs are specifically designed to work
+ with namespaces.
+
+* localedef now accepts locale definition files encoded in UTF-8.
+ Previously, input bytes not within the ASCII range resulted in
+ unpredictable output.
+
+* Support for the mbrtoc8 and c8rtomb multibyte/UTF-8 character conversion
+ functions has been added per the ISO C2X N2653 and C++20 P0482R6 proposals.
+ Support for the char8_t typedef has been added per the ISO C2X N2653
+ proposal. The functions are declared in uchar.h in C2X mode or when the
+ _GNU_SOURCE macro or C++20 __cpp_char8_t feature test macro is defined.
+ The char8_t typedef is declared in uchar.h in C2X mode or when the
+ _GNU_SOURCE macro is defined and the C++20 __cpp_char8_t feature test macro
+ is not defined (if __cpp_char8_t is defined, then char8_t is a builtin type).
+
+* The functions arc4random, arc4random_buf, and arc4random_uniform have been
+ added. The functions wrap getrandom and/or /dev/urandom to return high-
+ quality randomness from the kernel.
+
+* Support for LoongArch running on Linux has been added. This port requires
+ as least binutils 2.38, GCC 12, and Linux 5.19. Currently only hard-float
+ ABI is supported:
+
+ - loongarch64-linux-gnu
+
+ The LoongArch ABI is 64-bit little-endian.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* Support for prelink will be removed in the next release; this includes
+ removal of the LD_TRACE_PRELINKING, and LD_USE_LOAD_BIAS, environment
+ variables and their functionality in the dynamic loader.
+
+* The Linux kernel version check has been removed along with the
+ LD_ASSUME_KERNEL environment variable. The minimum kernel used to built
+ glibc is still provided through NT_GNU_ABI_TAG ELF note and also printed
+ when libc.so is issued directly.
+
+* On Linux, The LD_LIBRARY_VERSION environment variable has been removed.

Version 2.35
Major new features:
* On Linux, the epoll_pwait2 function has been added. It is similar to
epoll_wait with the difference the timeout has nanoseconds resolution.
-* The functions posix_spawnattr_tcsetpgrp_np and posix_spawnattr_tcgetpgrp_np
- have been added, enabling posix_spawn and posix_spawnp to set the
- controlling terminal in the new process in a race free manner. These
- functions are GNU extensions.
+* The function posix_spawn_file_actions_addtcsetpgrp_np has been added,
+ enabling posix_spawn and posix_spawnp to set the controlling terminal in
+ the new process in a race free manner. This function is a GNU extension.
* Source fortification (_FORTIFY_SOURCE) level 3 is now available for
applications compiling with glibc and gcc 12 and later. Level 3 leverages
fortification balanced against additional runtime cost (checking non-constant
bounds).
+* The audit libraries will avoid unnecessary slowdown if it is not required
+ PLT tracking (by not implementing the la_pltenter or la_pltexit callbacks).
+
Deprecated and removed features, and other changes affecting compatibility:
* On x86-64, the LD_PREFER_MAP_32BIT_EXEC environment variable support
removal of the LD_TRACE_PRELINKING, and LD_USE_LOAD_BIAS, environment
variables and their functionality in the dynamic loader.
+* The LD_TRACE_PRELINKING environment variable has been removed. Similar
+ functionality to obtain the program mapping address can be achieved by
+ using LD_TRACE_LOADED_OBJECTS to value of 2.
+
+* The LD_USE_LOAD_BIAS has been removed. The variable was mainly used to
+ support prelink PIE binaries.
+
+Changes to build and runtime requirements:
+
* The audit module interface version LAV_CURRENT is increased to enable
proper bind-now support. The loader now advertises via the la_symbind
- flags that PLT trace is not possible.
+ flags that PLT trace is not possible. New audit modules require the
+ new dynamic loader supporting the latest LAV_CURRENT version. Old audit
+ modules are still loaded for all targets except aarch64.
* The audit interface on aarch64 is extended to support both the indirect
result location register (x8) and NEON Q register. Old audit modules are
- rejected by the loader.
-
-Changes to build and runtime requirements:
-
- [Add changes to build and runtime requirements here]
+ rejected by the loader. Audit modules must be rebuilt to use the newer
+ structure sizes and the latest module interface version for LAV_CURRENT.

Version 2.7
* The `btowc' function should work at least twice as fast due to
specialized callbacks in the iconv modules. Implemented by Bruno Haible.
-* With approriate thread add-ons cancelable functions are now implemented
+* With appropriate thread add-ons cancelable functions are now implemented
in libc.so as well. No need to call the function in libpthread. This
change allowed to finally disable the incorrect and expensive handling
of weak definition in ld.so.
* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
symbol level.
-* Miles Bader provided the `argp' function family to support hierachical
+* Miles Bader provided the `argp' function family to support hierarchical
command line argument parsing, layered on top of getopt.
* strtod accepts new hexadecimal floating-point format from ISO C 9X.
* Ulrich Drepper has contributed a new suite of functions for operation on
wide-character and multibyte-character strings, in <wchar.h>;
and classification and case conversion of wide characters, in <wctype.h>.
- These new functions are conforming to the ISO C, Amendement 1 specification.
