+
+* Optimized strchr implementation for AArch64. Contributed by ARM Ltd.
+
+* The minimum Linux kernel version that this version of the GNU C Library
+ can be used with is 2.6.32.
* Running the testsuite no longer terminates as soon as a test fails.
Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
interfaces those macros enabled remain available when compiling with
_GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
test macros defined.
+
+* Optimized strcmp implementation for ARMv7. Contributed by ARM Ltd.
+
+* Added support for TX lock elision of pthread mutexes on s390 and s390x.
+ This may improve lock scaling of existing programs on TX capable systems.
+ The lock elision code is only built with --enable-lock-elision=yes and
+ then requires a GCC version supporting the TX builtins. With lock elision
+ default mutexes are elided via __builtin_tbegin, if the cpu supports
+ transactions. By default lock elision is not enabled and the elision code
+ is not built.
+
+* CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
+ copy the path argument. This allowed programs to cause posix_spawn to
+ deference a dangling pointer, or use an unexpected pathname argument if
+ the string was modified after the posix_spawn_file_actions_addopen
+ invocation.
+
+* All supported architectures now use the main glibc sysdeps directory
+ instead of some being in a separate "ports" directory (which was
+ distributed separately before glibc 2.17).
+
+* The NPTL implementation of POSIX pthreads is no longer an "add-on".
+ On configurations that support it (all Linux configurations), it's now
+ used regardless of the --enable-add-ons switch to configure. It is no
+ longer possible to build such configurations without pthreads support.
+
+* Locale names, including those obtained from environment variables (LANG
+ and the LC_* variables), are more tightly checked for proper syntax.
+ setlocale will now fail (with EINVAL) for locale names that are overly
+ long, contain slashes without starting with a slash, or contain ".." path
+ components. (CVE-2014-0475) Previously, some valid locale names were
+ silently replaced with the "C" locale when running in AT_SECURE mode
+ (e.g., in a SUID program). This is no longer necessary because of the
+ additional checks.
