0.2.1 Release Notes

🚨 Highlights & Breaking Changes

• MSMP Replaced RCON (Breaking): Legacy RCON has been removed from the server core and replaced with the modern Minecraft Server Management Protocol (MSMP) over JSON-RPC. Server configuration has migrated from rcon to management.
• Pump Default Chunk Storage (Breaking / Migration): pump is now the default chunk storage format for world saving and loading, replacing Anvil for higher throughput and reduced disk footprint. A built-in chunk converter and CLI migration tool have been added to convert existing Anvil worlds.
• Server Crate Architecture Split: Refactored the core monolithic server crate into modular crates: pumpkin-core, pumpkin-wasm-host (-common, -v0_1, -v0_2), and the standalone pumpkin binary (#3824) by @Phoenixxo. Master release builds now use optimized Thin LTO, while full Fat-LTO binaries are generated nightly.
• PatchBukkit Integration Support: Exposed critical low-level plugin APIs (Context, PluginManager.handlers, world/player event hooks, #[repr(C)] layouts) to support PatchBukkit running headless Paper and real NMS plugins on Pumpkin.
• Mob AI Foundation Overhaul: Completely reworked entity AI execution flow (#4092) by @MegalithOfficial. Decoupled brain state from behavior execution, routed mob navigation through movement controls, and preserved path searches across tick steps.
• Async v0.2 Plugin ABI: Branched and stabilized the new asynchronous v0.2 WebAssembly plugin ABI (#3713, #3766, #3852) by @Phoenixxo and @QuantumSegfault, alongside upgrading Wasmtime to 50.0.0 with sequential engine isolation for v0.1 plugins (#4098).
