What will happen with my new system (dates/tags) when testflight is over? Will OF3 be released before?

Can anyone tell me what will happen to my tags, new dates, etc. when testflight is over?
When would it be possible to test the web version? :-)

btw I’m defenently gonna buy omnifocus 3 for ios and mac! 👍

The TestFlight windows are pretty long, I’ve got 89 days on mine and they’re reset with every update. I imagine by the time Omni ship OF3 you’ll have a weeks to buy the release before your TestFlight expires and as long as your data is synced, the changeover will be seamless.
