 - scanf now handles the %l[ conversion.
 
+- Improved hostprogs compatibility for cross-compiling the Linux kernel.
+New headers: <asm/bitsperlong.h>, <asm/posix_types.h>.
+
+- Built-in implementation of Stack Smashing Protection compiler feature.
+New APIs: __stack_chk_fail, __stack_chk_guard.
+
+- Built-in implementation of _FORTIFY_SOURCE guards for functions in
+<stdio.h>, <stdlib.h>, <string.h>, <strings.h>, <unistd.h>, <wchar.h>,
+<sys/poll.h>, and <sys/socket.h>.
+New APIs:  __chk_fail, __gets_chk, __memcpy_chk, __memmove_chk, __mempcpy_chk,
+__memset_chk, __snprintf_chk, __sprintf_chk, __stpcpy_chk, __stpncpy_chk,
+__strcat_chk, __strcpy_chk, __strncat_chk, __strncpy_chk, __vsnprintf_chk,
+__vsprintf_chk.
+
+- Built-in implementation of POSIX.1-2001 message catalog support.
+New APIs: catclose, catgets, catopen.  New tool: gencat.
+
 - New APIs: sigtimedwait, wmempcpy.
 
 
 What changed:
 -------------
 
+- Standard headers no longer use macros to support K&R C.
+
+- confstr(3) and getconf(1) accept LFS_CFLAGS, LFS_LDFLAGS, etc.
+
+- The __always_inline and __nonnull macros in <sys/cdefs.h> are now
+compatible with glibc.
+
+- Feature Test Macros improvements in <fcntl.h>, <limits.h>, <netdb.h>,
+<strings.h>, and <unistd.h>.
