The instructions for 7.6β say:
You must ensure that the other members of the project team have upgraded
Paratext before you opt-in these features on the shared project.
Upgrade options are:
Upgrade team members to 7.5.100.46 or later.
Team members will be unable to use Project Interlinearizer, Word
List, and Guess Translations, but can do other work. -or-Upgrade team members to the 7.6 Beta Test Version.
Team members will need setup and training, will be more at risk
of unexpected problems, and you will need to support them.
We have a lot of observers on our project, and none of them are in the same geographical location. I also have no way of knowing what version they currently have, apart from emailing them (and then, for some of them, emailing them again and again before I get an answer).
Or is it OK for users in an Observer role to have PT <7.5.100.46, since they can’t edit the text?
The feature where PT 7.6β2 flags out of date copies of PT in the summary it gives after an S/R is really nice … but it would be even nicer if it could tell you the PT version of all the users (the version they had the last time they S/R’ed). Then I could tell the relevant users to upgrade and do an S/R, and I’d know for sure that they really were on the latest version.
