• ported to neoforge 1.21.1 yayyy
• fixed chunks not syncing for some players (broadcast never marked chunks as synced)
• unified the sync radius across all paths so every player gets the same chunks
• fixed unfair sync: worker now round-robins players instead of always favoring the first
• new players now get a prioritized backfill of already-generated chunks on join
• two-way handshake: server now knows which clients have the mod and skips vanilla clients
• block edits now sync only the changed section instead of re-uploading the whole chunk column
• client ingests lod data nearest-first so chunks fill from the player outward, no more far ring
• client ingest is rate-limited per tick to keep client fps smooth
• packet batching offloaded off the server tick thread
• per-player synced-chunk sets are pruned so they don't grow forever
• config screen split into client and server tabs so it's clear what affects the server
• server config tab is read-only for non-ops, shows the server's real values
• ops can edit server config from the client and it pushes to the server live (no restart)
• packet size budgeting accounts for framing overhead
• first-run config scales max parallel tasks to cpu core count

in short the networking is a lot more stable and performant!

could have bugs, use with caution
