 *** Changes since GDB 8.2
 
+* GDB and GDBserver now support access to additional registers on

 * GDB now has experimental support for the compilation and injection of
   C++ source code into the inferior.  This beta release does not include
   support for several language features, such as templates, constructors,

 * DWARF index cache: GDB can now automatically save indices of DWARF
   symbols on disk to speed up further loading of the same binaries.

   executed failed.

   unchanged.  The MI comment "-stack-select-frame" is unchanged.
 
+* The RISC-V target now supports target descriptions.
+
+* System call catchpoints now support system call aliases on FreeBSD.
+  When the ABI of a system call changes in FreeBSD, this is
+  implemented by leaving a compatibility system call using the old ABI
+  at the existing number and allocating a new system call number for
+  the new ABI.  For example, FreeBSD 12 altered the layout of 'struct
+  kevent' used by the 'kevent' system call.  As a result, FreeBSD 12
+  kernels ship with both 'kevent' and 'freebsd11_kevent' system calls.
+  The 'freebsd11_kevent' system call is assigned an alias of 'kevent'
+  so that a system call catchpoint for the 'kevent' system call will
+  catch invocations of both the 'kevent' and 'freebsd11_kevent'
+  binaries.  This ensures that 'kevent' system calls are caught for
+  binaries using either the old or new ABIs.
