All,

I have loaded and am current running -rc4.  It seems to work well.  There
are a couple of caveats and the potential for some chaos in the January VHF
contest:

   1. For the entire v2.x series MSK144 generated by version 1.9.1 cannot
   be decoded by V2.x and visa-versa.  The GA release of v2.x should be out
   before December 31 and I suggest we all need to be on it.
   2. Effective with -rc4 the system only supports the 77 bit version of
   the FT8 messages.  That means -rc4 cannot decode messages generated by
   1.9.1 and the other way around.  For now -rc4 users are staying above 2000
   Hz to try and minimize confusion. With the GA release of v2.x due the end
   of December there could be some adventures as people who have not been
   keeping track of developments  start reporting "no decodes.".  Again, for
   the contest suggest we all need to be on V2.x
   3. In the good news column, v2.x autosequence handles NA contest mode
   exchanges and "casual" (signal report) exchanges very nicely.  So that
   should take care of that problem.  No more switching back and forth
   midstream as contesters and general users get all mixed together.

Hope to see you all on the air for the January contest.  If you do decide
to use FT8 or MSK144 probably time to upgrade to -rc4 for a trial run and
to the GA release NLT December 31 for sure.  here is the URL:
