+* Unicode 8.0.0 Support: Character encoding, character type info, and
+ transliteration tables are all updated to Unicode 8.0.0, using new
+ and/or improved generator scripts contributed by Mike FABIAN (Red Hat).
+ These updates cause user visible changes, such as the fixes for bugs
+ 89, 16061, and 18568.
+
+* sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
+ kernel-internal CPU set size. This means that requests that change the
+ CPU affinity which failed before (for example, an all-ones CPU mask) will
+ now succeed. Applications that need to determine the effective CPU
+ affinities need to call sched_getaffinity or pthread_getaffinity_np after
+ setting it because the kernel can adjust it (and the previous size check
+ would not detect this in the majority of cases).
+
+* The fts.h header can now be used with -D_FILE_OFFSET_BITS=64. With LFS
+ the following new symbols are used: fts64_children, fts64_close,
+ fts64_open, fts64_read and fts64_set.
+
+* getaddrinfo now detects certain invalid responses on an internal netlink
+ socket. If such responses are received, an affected process will
+ terminate with an error message of "Unexpected error <number> on netlink
+ descriptor <number>" or "Unexpected netlink response of size <number> on
+ descriptor <number>". The most likely cause for these errors is a
+ multi-threaded application which erroneously closes and reuses the netlink
+ file descriptor while it is used by getaddrinfo.
+
+* A defect in the malloc implementation, present since glibc 2.15 (2012) or
+ glibc 2.10 via --enable-experimental-malloc (2009), could result in the
+ unnecessary serialization of memory allocation requests across threads.
+ The defect is now corrected. Users should see a substantial increase in
+ the concurent throughput of allocation requests for applications which
+ trigger this bug. Affected applications typically create create and
+ destroy threads frequently. (Bug 19048 was reported and analyzed by
+ Ericsson.)
+
+* There is now a --disable-timezone-tools configure option for disabling the
+ building and installing of the timezone related utilities (zic, zdump, and
+ tzselect). This is useful for people who build the timezone data and code
+ independent of the GNU C Library.
* The LD_POINTER_GUARD environment variable can no longer be used to
disable the pointer guard feature. It is always enabled.
* The obsolete header <regexp.h> has been removed. Programs that require
this header must be updated to use <regex.h> instead.
+* The obsolete functions bdflush, create_module, get_kernel_syms,
+ query_module and uselib are no longer available to newly linked binaries;
+ the header <sys/kdaemon.h> has been removed. These functions and header
+ were specific to systems using the Linux kernel and could not usefully be
+ used with the GNU C Library on systems with version 2.6 or later of the
+ Linux kernel.
+
* Optimized string, wcsmbs and memory functions for IBM z13.
Implemented by Stefan Liebler.
+
+* Newly linked programs that define a variable called signgam will no longer
+ have it set by the lgamma, lgammaf and lgammal functions. Programs that
+ require signgam to be set by those functions must ensure that they use the
+ variable provided by the GNU C Library and declared in <math.h>, without
+ defining their own copy.
+
+* The minimum GCC version that can be used to build this version of the GNU
+ C Library is GCC 4.7. Older GCC versions, and non-GNU compilers, can
+ still be used to compile programs using the GNU C Library.
+
+Security related changes:
+
+* The nan, nanf and nanl functions no longer have unbounded stack usage
+ depending on the length of the string passed as an argument to the
+ functions. Reported by Joseph Myers.
+
+* The following bugs are resolved with this release:
+
+ [The release manager will add the list generated by
+ scripts/list-fixed-bugs.py just before the release.]
