    The GNU C Library version 2.36 is now available
    The GNU C Library
    The GNU C Library version 2.36 is now available.
    The GNU C Library is used as *the* C library in the GNU system and
    in GNU/Linux systems, as well as many other systems that use Linux
    as the kernel.
    The GNU C Library is primarily designed to be a portable
    and high performance C library.  It follows all relevant
    standards including ISO C11 and POSIX.1-2017.  It is also
    internationalized and has one of the most complete
    internationalization interfaces known.
    The GNU C Library webpage is at
    Packages for the 2.36 release may be downloaded from:

    NEWS for 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 tranditional 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 is issued directly.
    * On Linux, The LD_LIBRARY_VERSION environment variable has been removed.
