GlymeraIrrigation — Changelog

v4.0.0 (2026-05-30)

Changed (performance — no behaviour change)

• The 30-second discovery scan (which previously scanned every loaded chunk for farmland and water in a single server tick) is now amortized across many ticks in small bounded slices. This removes the once-per-cycle tick stutter on large farms.
• The water → farmland reverse lookup is now computed once per discovery pass and reused by every 10-second irrigation scan, instead of being rebuilt on every scan.

Fixed

• Hardened a restart edge case introduced by the amortized discovery: until the first discovery pass has fully completed after a restart, the irrigation scan now skips (instead of treating "no data yet" as "no water nearby"). This guarantees that already-watered fields — whose watered state is persisted by the game — are never wrongly dried out during the warm-up window. The per-block watered persistence mechanism itself (the external-water flag + watered-until time) is unchanged.

Unchanged

• Irrigation radius (4 blocks), watered-state persistence across chunk reload and server restart, and the "only dehydrate our own blocks" behaviour (watering-can fixes remain). No config migration.

Notes

• Server restart required to load the new JAR.
• Earlier versions (up to v3.0.0) were internal builds and were not separately documented.
