Version 2.26
-* Unicode 9.0.0 Support: Character encoding, character type info, and
- transliteration tables are all updated to Unicode 9.0.0, using
+* Unicode 10.0.0 Support: Character encoding, character type info, and
+ transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
+* errno.h is now safe to use from C-preprocessed assembly language on all
+ supported operating systems. In this context, it will only define the
+ Exxxx constants, as preprocessor macros expanding to integer literals.
+
* The rpcgen, librpcsvc and related headers will only be built and
installed when glibc is configured with --enable-obsolete-rpc.
This allows alternative RPC implementations, like TIRPC, to be used
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
+* <string.h> no longer includes inline versions of any string functions,
+ as this kind of optimization is better done by the compiler. The macros
+ __USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
+
+* The nonstandard header <xlocale.h> has been removed. Most programs should
+ use <locale.h> instead. If you have a specific need for the definition
+ of locale_t with no other declarations, please talk to us.
+
+* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
+
* The reallocarray function has been added to libc. It is a realloc
replacement with a check for integer overflow when calculating total
allocation size.
as atomic variables to try to implement Dekker's mutual exclusion
algorithm).
+* The tunables feature is now enabled by default. This allows users to tweak
+ behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
+
+* The s390 specific ptrace requests are adjusted to the kernel ones. Request 12
+ is now used for PTRACE_SINGLEBLOCK instead of PTRACE_GETREGS. The requests
+ PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS were
+ removed as those are not supported by the s390 kernel. The requests
+ PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
+ PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
+ PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND were added as those are supported
+ by the s390 kernel.
+
+* The minimum GCC version that can be used to build this version of the GNU
+ C Library is GCC 4.9. Older GCC versions, and non-GNU compilers, can
+ still be used to compile programs using the GNU C Library.
+
+* Support is added, on powerpc64le, for interfaces supporting the _Float128
+ type from ISO/IEC TS 18661-3:2015. Most of the interfaces are taken from
+ TS 18661-3. The type-generic macros in <math.h> support this type, but
+ those in <tgmath.h> do not. The GNU C Library now requires GCC 6.2 or
+ later to build for powerpc64le. When used with GCC versions before GCC
+ 7, these interfaces may be used with the type under the non-standard name
+ __float128.
