Voxy WorldGen

• fixed config settings not saving on fabric, you could turn generation off but not back on without reinstalling the mod
• config screen now shows your actual saved settings instead of whatever the last server you joined was using
• settings you change in singleplayer now stick when you reopen the config screen
• leaving a server with the config screen open no longer overwrites your local settings with that server's
• your client-only settings no longer get wiped when the server reloads its config
• a broken or empty config file no longer wipes all your settings on startup
• stopped the chunk scan from re-running several times a second while you're moving around
• fixed lag spikes when the LOD send queue backed up during heavy generation
• fixed a rare bug where a finished chunk could get lost and the generator would keep regenerating the same area forever
• fixed world data being held in memory after leaving a world

have had this sitting in #testing for a while and finally decided to update here!

• same as below

• fixed players without the mod getting kicked with invalid player data when joining a neoforge server, the mod is optional now and vanilla clients just don't get lod data
• stopped generating chunks around players who don't have the client mod, no point since they can't render it anyway
• active task count in f3 holds steady near your configured max instead of bouncing between the cap and a low number, load easing is smoothed now
• fixed chunks generating unevenly when lots of players are on (one player used to hog all the work, now it's split fairly)
• fixed catch-up leaving permanent white holes (chunk got marked synced even when it never sent)
• chunk loads no longer spam every player every time, skips people who lack the mod or already have the chunk
• block edits no longer tax every single block change on the server, bails early when no one has the mod
• dirty section backlog is capped now so a redstone/fluid storm can't blow up memory
• block edit resend timing actually uses the update_interval config instead of a hardcoded value
• send queue is capped so a broadcast storm can't grow memory forever
• stopped sending chunks to players who already left or walked out of range
• synced chunks get cleared on dimension change so old stuff doesn't block syncing in the new world
• client ingest sorts once per tick instead of scanning the whole queue every time, way less lag
• when the queue overflows it drops the farthest chunk instead of the oldest
• empty block light is sent as null now instead of a dead 2048 byte array, saves bandwidth
• added a protocol version to the handshake so mismatched versions just don't sync instead of breaking
• fabric client ingest now matches the neoforge design (queued + drained per tick nearest-first)
• you can use config menu on server to edit server config if your op

• fixed world stuck in saving when closing it

• 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

• fix crash when opening f3+f6 menu (allEntries returns unmodifiable map)
• default status to IN_OVERLAY so entry shows without manual enable
• remove showF3MenuStats config option (redundant, use f3+f6 menu instead)
• bump to minecraft 26.1.2, fabric-api 0.147.0+26.1.2

• fixed nether blocks rendering incorrectly in overworld after dimension switch
• fixed hard biome blend edges and snow artifacts on new world creation
• fixed generation continuing when voxy is disabled in its settings
• re-ingests chunks on load so voxy receives correct biome neighbor context
• discards LOD packets from mismatched dimensions to prevent cross-dimension rendering corruption
• pauses background generation worker when voxy rendering is turned off

This will be the last 1.21.6-1.21.11 update, everything will be 26.1+ from now on.

• fixed chunk synchronization for completed chunks that are not yet loaded into memory
• added chunk-load event hook to sync LOD data when completed chunks load naturally
• marked completed chunks as synced upfront to prevent tight re-queueing loops
• fixed throttling/lag when chunk generation finishes by breaking sync batch retry cycle
• prevented unloaded chunks from blocking synced chunk tracking indefinitely
• fixed memory leak
