+ 6652, 10672, 12847, 12926, 13862, 14132, 14138, 14171, 14498, 15215,
+ 15884, 16191, 16469, 16617, 16619, 16657, 16740, 16857, 17192, 17266,
+ 17273, 17344, 17363, 17370, 17371, 17411, 17460, 17475, 17485, 17501,
+ 17506, 17508, 17522, 17555, 17570, 17571, 17572, 17573, 17574, 17582,
+ 17583, 17584, 17585, 17589, 17594, 17601, 17608, 17616, 17625, 17630,
+ 17633, 17634, 17635, 17647, 17653, 17657, 17658, 17664, 17665, 17668,
+ 17682, 17717, 17719, 17722, 17723, 17724, 17725, 17732, 17733, 17744,
+ 17745, 17746, 17747, 17748, 17775, 17777, 17780, 17781, 17782, 17791,
+ 17793, 17796, 17797, 17806
+
+* Optimized strcpy, stpcpy, strchrnul and strrchr implementations for
+ AArch64. Contributed by ARM Ltd.
+
+* i386 memcpy functions optimized with SSE2 unaligned load/store.
+
+* CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag
+ under certain input conditions resulting in the execution of a shell for
+ command substitution when the applicaiton did not request it. The
+ implementation now checks WRDE_NOCMD immediately before executing the
+ shell and returns the error WRDE_CMDSUB as expected.
+
+* CVE-2012-3406 printf-style functions could run into a stack overflow when
+ processing format strings with a large number of format specifiers.
+
+* CVE-2014-9402 The nss_dns implementation of getnetbyname could run into an
+ infinite loop if the DNS response contained a PTR record of an unexpected
+ format.
+
+* The minimum GCC version that can be used to build this version of the GNU
+ C Library is GCC 4.6. Older GCC versions, and non-GNU compilers, can
+ still be used to compile programs using the GNU C Library.
+
+* The GNU C Library is now built with -Werror by default. This can be
+ disabled by configuring with --disable-werror.
+
+* New locales: tu_IN, bh_IN, raj_IN, ce_RU.
+
+* The obsolete sigvec function has been removed. This was the original
+ 4.2BSD interface that inspired the POSIX.1 sigaction interface, which
+ programs have been using instead for about 25 years. Of course, ABI
+ compatibility for old binaries using sigvec remains intact.
+
+* Merged gettext 0.19.3 into the intl subdirectory. This fixes building
+ with newer versions of bison.
+
+* Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions.
+ The original MIPS o32 hard-float ABI requires an FPU where double-precision
+ registers overlay two consecutive single-precision registers. MIPS32R2
+ introduced a new FPU mode (FR=1) where double-precision registers extend the
+ corresponding single-precision registers which is incompatible with the
+ o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both
+ require the use of FR=1 making a transition necessary. New o32 ABI
+ extensions enable users to migrate over time from the original o32 ABI
+ through to the updated o32 FP64 ABI. To achieve this the dynamic linker now
+ tracks the ABI of any loaded object and verifies that new objects are
+ compatible. Mode transitions will also be requested as required and
+ unsupportable objects will be rejected. The ABI checks include both soft and
+ hard float ABIs for o32, n32 and n64.
+
+ GCC 5 with GNU binutils 2.25 onwards:
+ It is strongly recommended that all o32 system libraries are built using the
+ new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible
+ with the original and all new o32 ABI extensions. Configure a MIPS GCC
+ compiler using --with-fp-32=xx to set this by default.
