Hytale Update 6 (0.6.0) compatibility release

This changelog applies to every GlymeraCraft plugin released on 2026-08-28. The text is identical for all plugins.

What changed in Hytale 0.6.0

Hytale Update 6 (server version 0.6.0, released 27 August 2026) is a breaking update for server plugins:

• New network protocol (hytale/3). Every plugin has to be rebuilt against the 0.6.0 server. Jars built for 0.5.x do not work on 0.6.0.
• Command permissions. The old way of opening a command to all players (canGeneratePermission) is no longer called by the server. Plugins that still use it have all of their player commands silently locked to operators.
• Block API rework. Per-block helpers on WorldChunk (rotation, break, place) were removed, block entities are now stored per chunk section, and several chunk/section accessors changed signatures.
• NPC support objects moved to ECS components (marked entities, world support, state support); NPC actions receive an execution-support handle.
• Movement settings: flying is now a three-state FlyMode (Disabled / Allowed / Forced); MovementConfig assets gained new required slope/wall-angle keys.
• Stricter asset validation. The server now stops on invalid NPC role parameters and other asset errors instead of logging a warning. One removed vanilla NPC template (Template_Aggressive_Zombies) breaks packs that referenced it.
• Client texture rules. Block textures must be a multiple of 32 px and at least 32×32; a single violating texture breaks the whole block-texture atlas for every player on the server.
• World-thread stability. Entity spatial lookups changed (SpatialStructure.collect); old jars using them crash the world thread on 0.6.0.

What we did

All GlymeraCraft plugins were rebuilt and adapted for 0.6.0:

• Rebuilt against the 0.6.0 server (protocol hytale/3).
• Player commands migrated to the new permission API — everything that was open to players before is open to players again.
• Block, chunk-section and block-entity code migrated to the new API.
• NPC plugins migrated to the ECS support components and the new action signature.
• Fly/movement handling migrated to FlyMode; movement configs completed with the new keys.
• NPC roles and templates fixed for the stricter validation.
• Block textures padded to the 32 px grid where needed.
• Entity lookups migrated so world threads no longer crash.

Each plugin was booted and tested in-game on 0.6.0 before this release.

Upgrading

1. Update your server to Hytale 0.6.0 (or newer 0.6.x).
2. Delete the old plugin jar from mods/ and drop in the new one. Keep the plugin's data folder (mods/de.glymera_<Plugin>/) — configs and saved data carry over unchanged.
3. Restart the server.

Do not run the previous versions on 0.6.0. Depending on the plugin they either fail to load, lock all player commands to OPs, or crash the world thread shortly after boot.

Known limitations on 0.6.0

• GlymeraStatues is not available for 0.6.0 yet: its block-texture set exceeds the client's texture-atlas limit introduced in Update 6 and would crash every joining client. It will return in a reworked version.
• Hytale 0.6.1 (hotfix, 28 August) changes nothing on the plugin side — these releases work on 0.6.0 and 0.6.1.
