 Major new features:
 
+* Unicode 12.1.0 Support: Character encoding, character type info, and
+  transliteration tables are all updated to Unicode 12.1.0, using
+  generator scripts contributed by Mike FABIAN (Red Hat).
+
 * The dynamic linker accepts the --preload argument to preload shared
   objects, in addition to the LD_PRELOAD environment variable.
 
+* The twalk_r function has been added.  It is similar to the existing
+  twalk function, but it passes an additional caller-supplied argument
+  to the callback function.
+
+* On Linux, the gettid function has been added.
+
+* Minguo (Republic of China) calendar support has been added as an
+  alternative calendar for the following locales: zh_TW, cmn_TW, hak_TW,
+  nan_TW, lzh_TW.
+
+* The entry for the new Japanese era has been added for ja_JP locale.
+
+* Memory allocation functions malloc, calloc, realloc, reallocarray, valloc,
+  pvalloc, memalign, and posix_memalign fail now with total object size
+  larger than PTRDIFF_MAX.  This is to avoid potential undefined behavior with
+  pointer subtraction within the allocated object, where results might
+  overflow the ptrdiff_t type.

 Deprecated and removed features, and other changes affecting compatibility:
 
-  [Add deprecations, removals and changes affecting compatibility here]
+* The functions clock_gettime, clock_getres, clock_settime,
+  clock_getcpuclockid, clock_nanosleep were removed from the librt library
+  for new applications (on architectures which had them).  Instead, the
+  definitions in libc will be used automatically, which have been available
+  since glibc 2.17.
+
+* The obsolete and never-implemented XSI STREAMS header files <stropts.h>
+  and <sys/stropts.h> have been removed.
+
+* Support for the "inet6" option in /etc/resolv.conf and the RES_USE_INET6
+  resolver flag (deprecated in glibc 2.25) have been removed.
+
+* The obsolete RES_INSECURE1 and RES_INSECURE2 option flags for the DNS stub
+  resolver have been removed from <resolv.h>.
+
+* With --enable-bind-now, installed programs are now linked with the
+  BIND_NOW flag.
