Which PLEG version best on UI5?

I wanted to know if the PLEG update for UI7 still works well with UI5.

I’m on PLEG 7.1 and it’s working fine. Should I upgrade or not?

My releases are al for UI5,UI6, and UI7
There is a forum topic that lists all of the changes.
It’s the first entry … So you do not need to read through the whole topic.
Most of the recent changes have been for UI7.
The next release has a new operator that is useful if you use the google calendar plugin.
