  18594, 18602, 18612, 18613, 18619, 18633, 18635, 18641, 18643, 18648,
  18657, 18676, 18694, 18696.

* Cache information can be queried via sysconf() function on s390 e.g. with
  _SC_LEVEL1_ICACHE_SIZE as argument.

* A buffer overflow in gethostbyname_r and related functions performing DNS
  requests has been fixed.  If the NSS functions were called with a
  misaligned buffer, the buffer length change due to pointer alignment was
  not taken into account.  This could result in application crashes or,
  potentially arbitrary code execution, using crafted, but syntactically
  valid DNS responses.  (CVE-2015-1781)

* The time zone file parser has been made more robust against crafted time
  zone files, avoiding heap buffer overflows related to the processing of
  the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
  large time zone data files.  Overly long time zone specifiers in the TZ
  variable no longer result in stack overflows and crashes.

* A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
  for LD and GD on x86 and x86-64, has been implemented.  You will need
  binutils-2.24 or later to enable this optimization.

* Character encoding and ctype tables were updated to Unicode 7.0.0, using
  new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red
  Hat).  These updates cause user visible changes, such as the fix for bug
  17998.

* CVE-2014-8121 The NSS backends shared internal state between the getXXent
  and getXXbyYY NSS calls for the same database, causing a denial-of-service
  condition in some applications.

* Added vector math library named libmvec with the following vectorized x86_64
  implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf,
  pow, powf.
  The library can be disabled with --disable-mathvec. Use of the functions is
  enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0.
  Shared library libmvec.so is linked in as needed when using -lm (no need to
  specify -lmvec explicitly for not static builds).
  Visit <https://sourceware.org/glibc/wiki/libmvec> for detailed information.

* A new fmemopen implementation has been added with the goal of POSIX
  compliance. The new implementation fixes the following long-standing
  issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
  old implementation is still present for use be by existing binaries.

* The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
  releases.  It has been fixed to match 2.19 and older, but binaries built
  against 2.20 and 2.21 might need to be recompiled.  See BZ#18694.

* Port to Native Client running on ARMv7-A (--host=arm-nacl).
  Contributed by Roland McGrath (Google).

* The header <regexp.h> is deprecated, and will be removed in a future
  release.  Use of this header will trigger a deprecation warning.
  Application developers should update their code to use <regex.h> instead.
