What Ships Today
1.22.2 is the second patch in the 1.22 cycle, with three headline changes: 1) archaeology fixes — save migration logic now re-fills dig sites against updated sherd tables, which previously misaligned on upgrade; 2) sniffer AI rework — pathing no longer sticks on walls after sniffing out seeds, and breeding cooldowns are visible in difficulty settings; 3) an 11th round of chunk-pipeline optimization that noticeably cuts first-10-seconds lag on multiplayer servers.
Pre-Upgrade Checklist
Especially for datapack or modded server owners:
| Task | Why | Action |
|---|---|---|
| Back up worlds | Archaeology migration is irreversible | Copy saves or use server snapshots |
| Check datapacks | Some 1.22.1 tags changed | Verify version notes before upgrading |
| Wait for mods | Day-one Forge/Fabric support is partial | Upgrade after server cores ship |
| Keep snapshots | Release builds can't roll back | Use a separate instance |
Bedrock Parity & What's Next
Bedrock 1.22.2 ships in lockstep with matching sniffer behavior and a free marketplace map, 'Ruins Hunter'. By Mojang's rhythm, experimental features for 1.23 should open with the first snapshot in late October — the community bets on Twilight-scale End content, though nothing is confirmed.
