This is a patch release for everyone running 3.1.1 on an existing player database.

What was broken
3.1.0 introduced several new NOT NULL columns on existing tables (streak freezes, gift counters, jackpot stats). Those columns had no SQL default, so the ALTER TABLE step rolled back on servers with existing player data and vote storage failed to come up. Fresh installs were unaffected.

What 3.1.1 changes
Every new NOT NULL numeric / boolean column now carries a @ColumnDefault, so the migration can fill existing rows with 0 / false and the ALTER succeeds. No schema you can see has changed — the fix is purely in how the migration applies to pre-existing rows.

Upgrade
Drop the new JAR in and restart. Recovery is automatic. No manual SQL, no config edits, no data loss. If you were already on 3.1.0 and the plugin failed to enable, just update to 3.1.1 and start the server — the columns will backfill on first boot.

If you are on 3.0.x or earlier, go straight to 3.1.1 and skip 3.1.0.

For 3.1.11
we have made some further updates to designs, vote-party, vote-freezes, additional vote rewards and such.
