Thank you for the correction!

I've fallen behind on PR's and reviews on master, and missed that those 
actually went in.  :-(

Hold on there - that’s night quite a correct statement. The “prefer external” 
mechanism _is_ in place for PMIx and libevent - just not yet for hwloc (I 
believe).

Heads up: Arrgh.  It looks like we're going to miss this feature -- 
unfortunately, no one was able to devote enough time to finish it.  :-(

Sorry folks.  The existing "external" mechanisms will all still work, of 
course, but our configure script won't "prefer" them, so to speak.  So it's not 
a major deal for this feature to have missed v4.0.0, but it's still a bit of a 
bummer.

Hi Folks,

Definitely better to assume we will need to change the major version number.

I am HOPING it won't, but we have not done the analysis yet to determine if 
it's safe to NOT rev the .so version.  Best to assume it WILL rev.
We should know more before the end of the month.

I *believe* we have some incompatibilities coming, but I don't remember for 
sure.

Geoff / Howard: can you comment?
