+Version 2.17
+
+* The following bugs are resolved with this release:
+
+ 3479, 5400, 6778, 6808, 9685, 9914, 11607, 13412, 13717, 13696, 13939,
+ 13966, 14042, 14090, 14166, 14150, 14151, 14154, 14157, 14166, 14173,
+ 14195, 14252, 14283, 14298, 14303, 14307, 14328, 14331, 14336, 14337,
+ 14347, 14349, 14459, 14476, 14505, 14516, 14519, 14532, 14538
+
+* Support for STT_GNU_IFUNC symbols added for s390 and s390x.
+ Optimized versions of memcpy, memset, and memcmp added for System z10 and
+ zEnterprise z196.
+ Implemented by Andreas Krebbel.
+
+* The new function secure_getenv allows secure access to the environment,
+ returning NULL if running in a SUID/SGID process. This function replaces
+ the internal function __secure_getenv.
+
+* SystemTap static probes have been added into the dynamic linker.
+ Implemented by Gary Benson.
+
+* Optimizations of string functions strstr, strcasestr and memmem.
+ Implemented by Maxim Kuvyrkov.
+
+* The minimum Linux kernel version that this version of the GNU C Library
+ can be used with is 2.6.16.
+
+* Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
+ powerpc POWER7. Implemented by Will Schmidt.
+
+* New configure option --disable-nscd builds the C library such that it
+ never attempts to contact the Name Service Caching Daemon (nscd).
+ New configure option --disable-build-nscd avoids building nscd itself;
+ this is the default if --disable-nscd is used.
+
+* The ttyname and ttyname_r functions on Linux now fall back to searching for
+ the tty file descriptor in /dev/pts or /dev if /proc is not available. This
+ allows creation of chroots without the procfs mounted on /proc.

* Support for the x32 ABI on x86-64 added. The x32 target is selected by
configuring glibc with:
what x86-64 configurations install. These same header files can be used
for -m32, -m64, or -mx32 builds.
Contributed by H.J. Lu.
+
+* Math library bug fixes. A thorough audit of all open math library bugs was
+ conducted by Joseph Myers. Significant progress was made on many math
+ library bugs resulting in more accurate exceptions and function results.
+ Many thanks to all those that contributed including Andreas Jaeger for his
+ patch review and work on the x87 trigonometric instruction issues.
+
+* Timezone data is no longer installed. Timezone-related binaries and scripts
+ will continue to be installed. Users should obtain their timezone data from
+ their distribution provider or from the tzdata package at
+ <ftp://munnari.oz.au/pub/>.
