This update is not compatible with existing Iris worlds! The format of certain data structures has changed. Before using your existing worlds, please make a back up. There may be conversion errors, but Iris will try to simply re-generate corrupted data.
Loads of performance improvements in both generating in async & headless mode
Fixed a bug that caused downloads to fail
Fixed a problem that caused structures to be placed cut-off
Fixed a problem that was preventing noise features from generating correctly
Fixed initial spawns in spawners, villages now spawn entities
Iris now generates on a fork join pool at the lowest priority, this should allow Iris to generate faster when resources are available but also defer resources back to the server thread when needed.
Fixed several critical issues in the mantle preventing terrain from properly generating
Disabled decree (experimental commands) for now until they are ready
Fixed a few issues with pregen jobs not starting
Iris will no longer shut down engines on disable if they arent studio worlds. Because of this, you cannot disable / reload iris (or reload the server) with production worlds without risking corrupting production worlds.
