Unreleased

  • Breaking: Group.disconnect/3 now discards the complete local view of each departed cluster — remote entries included, and monitors receive :unregistered/:left events for them — instead of removing only locally owned rows. Reconnecting resyncs through the normal snapshot exchange. connect/disconnect also raise ArgumentError for non-binary cluster names instead of silently tolerating them.
  • The built-in registry conflict resolver now consistently includes the winner's metadata in the losing process's {:group_registry_conflict, key, winner_meta} exit reason. Custom resolve_registry_conflict callbacks remain responsible for any process exits they require.
  • Breaking: Group.dispatch/4 remote sends and process-DOWN replication are now non-suspending and never auto-connect — on a busy or disconnected distribution link the message is dropped, the link is force-disconnected, and bounded reconnect retries begin (the same policy replication lanes have used since 0.1.8). Previously dispatch could block the caller and initiate new connections.
  • Configured function-form extract_meta callbacks are now applied on reads and lifecycle events (previously they were silently ignored and full metadata was exposed), and invalid :extract_meta values raise ArgumentError at startup.
  • Group.lookup/3 no longer converts ArgumentError raised by metadata extraction callbacks into a nil miss; extractor errors now propagate to the caller.
  • Invalid :shards values (zero, negative, non-integer) raise ArgumentError at startup instead of failing later during key routing.

0.2.1 (2026-07-17)

  • Add bounded Group.members/3 queries with limit: and local-owner process-group queries through Group.local_members/3

0.2.0 (2026-04-17)

  • remove deprecate message handling

0.1.8 (2026-04-17)

  • Use send_nosuspend for remote shard sends and add bounded reconnect retries after busy-link disconnects to avoid any single bad link from blocking a shard

0.1.7 (2026-04-17)

  • Fix local shard request reply leaks by using reply aliases and draining any already-delivered timeout replies

0.1.6 (2026-04-16)

  • Add bounded local PG turn-taking and bulk local PG ETS application
  • Add sender-side replicated registry / PG batching by target node

0.1.5 (2026-04-14)

  • Add receiver-side batching and fairness for replicated registry traffic

0.1.4 (2026-03-31)

  • Add named-cluster Group.connect(..., ttl: ms) leases

0.1.3 (2026-03-31)

  • Add configurable timeouts to the public register/unregister/join/leave/connect/disconnect APIs

  • Buffer replicated PG join/leave receives with configurable receiver-side flush settings and bulk ETS application

0.1.2 (2026-03-30)

  • Optimize pg ops

0.1.1 (2026-03-19)

  • Optimize DOWN handling

0.1.0 (2026-02-12) 🚀

  • Initial release!
