Not sure if this is kosher or not, but, since nobody else has started one, here is a post to discuss issues or bugs found with 3.0 so far...
Opening an existing file and upgrading out of date devices causes all nions to be renamed to Nion #1 - and you cant change the name.
Two name fields under nion device properties - which don't work.
Expression naming for flyoffs doesn't work.

Thanks for your input, I'll pass this on to the engineers.

3.0 is still in beta? No additional releases? :-/
