Planned features for v0.3 have been implemented, and I have been running v0.3.0-beta.1-3 for a few months. Everything seems to work correctly. Tagging a v0.3.0 release.
New features:
- Restricted online DDL: Run large migrations without blocking concurrent read-only transactions.
- Overlay databases: Create writable snapshots as new "overlay" databases from a version of existing databases.
