 *** Changes since GDB 8.1
 
+* The 'symbol-file' command now accepts an '-o' option to add a relative
+  offset to all sections.
+
+* Similarly, the 'add-symbol-file' command also accepts an '-o' option to add
+  a relative offset to all sections, but it allows to override the load
+  address of individual sections using '-s'.
+
+* The 'add-symbol-file' command no longer requires the second argument
+  (address of the text section).
+
+* The endianness used with the 'set endian auto' mode in the absence of
+  an executable selected for debugging is now the last endianness chosen
+  either by one of the 'set endian big' and 'set endian little' commands
+  or by inferring from the last executable used, rather than the startup
+  default.
+
+* The pager now allows a "c" response, meaning to disable the pager
+  for the rest of the current command.
+
 * The commands 'info variables/functions/types' now show the source line
   numbers of symbol definitions when available.
 
 * 'info proc' now works on running processes on FreeBSD systems and core
   files created on FreeBSD systems.
 
+* C expressions can now use _Alignof, and C++ expressions can now use
+  alignof.
+
 * New commands

+* Aarch64/Linux hardware watchpoints improvements
+
+  Hardware watchpoints on unaligned addresses are now properly
+  supported when running Linux kernel 4.10 or higher: read and access
+  watchpoints are no longer spuriously missed, and all watchpoints
+  lengths between 1 and 8 bytes are supported.  On older kernels,
+  watchpoints set on unaligned addresses are no longer missed, with
+  the tradeoff that there is a possibility of false hits being
+  reported.
+
+* New configure options
+
+--enable-codesign=CERT
+  This can be used to invoke "codesign -s CERT" after building gdb.
+  This option is useful on macOS, where code signing is required for
+  gdb to work properly.
