How often does one get new versions of WSJT-X if compiling in JTSDK? I am *very* new to this and have been puzzled by the highest version I can compile being v5425, yet seeing board postings referring to higher versions (r5547 for e.g.).

The best place for questions about the development code is the wsjt-devel list on SourceForge.

New changes committed almost every day. You can subscribe to update messages about commits on SourceForge but I'm not sure if you need to be a registered developer to get them.

You can also browse repository commits here:

https://sourceforge.net/p/wsjt/wsjt/commit_browser

this shows all commits to all of Joe's projects but WSJT-X is by far the most active at the moment.
