I ran through most features except Location. I didn't get to it until about a half hour ago and it was a quick blitz, but here's what I found:
-I updated old events, single & recurrences - good.
-I added new events, single & recurrences - good.
-Registration for old & new events - good, EXCEPT the email for an event with no price shows a zero price, and shouldn't (condition: [events_if tag='#ESC_PRICE'] Class Fee: $#_PRICE [/events_if]).
-Paypal: my issue with the 'blank' screen remains - depressing :=(
-Email for event with "&" in event title: title displays incorrectly, and I don't believe that was true before - though I can't prove it as I didn't keep the old emails. Example: event title "test rsvp & no payment" displays as "test rsvp & no payment".
-People option is NOT displaying entries (db IS populated).
-Booking report - good.
-Event and Calendar displays - good.
-Settings: I thought I had set an Extra event html header field (I wouldn't swear to this, however!), but none was there after install/deact/react.
That's all for now... I am tired and must sleep. Hope this was helpful.
