+Changes since rc4:

+  - Various changes and cleanup to fix, and better support the static building of Open MPI.
+  - The PRRTE submodule pointer has been updated to bring in the following fixes:
+
+    - Added silent single-dash to double-dash conversion to the mpirun/mpiexec command
+      line. This promotes backwards compatibility with the v4.x series.
+    - Fixed a bug where launch-failure messages from PRRTE would be printed twice.
+  - Changes to the BTL ``OFI`` component to better support the HPE SS11 network.
+  - Fixed a compile failure when building with ``UCC`` (``configure --with-ucc=...``).
+  - Fixed several memory leaks in the ``UCX`` component.
+  - Fixed a bug where ``autogen.pl --force`` would fail. 
+  - Fixed a large number of warnings when compiling on macOS.
+  - Fixed two dead links in ``HACKING.md``. Thanks to Lachlan Bell for finding and fixing.
+  - Updated various documentation to rename ``master`` to ``main`` where relevant.
