The key word is experimental!
It might be unwise to "upgrade" your main/real gramps
family tree into 5.0.0-alpha2. In general, we recommend
you make a copy of your family tree instead (typically by
doing a "gramps XML" export), then try 5.0.0-alpha2 on
the copy. (You can keep things really separate by using
the GRAMPSHOME environmental variable, if you want.)
It's been about a year since 5.0.0-alpha1 was released
so we are interested in your feedback, especially if you
discover any bugs or problems which we haven't noticed.

Please file a bug report (selecting the "5.0.0-alpha2"
version) if you find one. We want testers for alpha2,
but only if you are sophisticated and resilient enough
to know how to keep it away from your real data.
