The status of 0.92 is that it does not exist yet.
There has been recent talk of us putting out a developer preview release of
0.92 soon. This would be versioned 0.91.
> 2) When do you plan to release 0.92 ?
I would not expect a release of 0.92 before mid year.
I don't know how Stack et. al. feel about it but I don't see why not a 0.91 DR
release could happen this month.

The rule is:
- Minor releases (e.g. 0.90.0 to 0.90.1) should not need data migration and
can be upgraded via a rolling restart
- Major releases (e.g. 0.90 to 0.92) may require data migration and may not
be upgradeable via a rolling restart

This will most likely be necessary.

It may not be necessary to perform a data migration step, but there is no
guarantee of this.
