KrepAPI (Mod)

KrepAPI 1.0.0

Added

• Initial release of KrepAPI: shared wire protocol plus a Fabric client mod and a reference Paper plugin for server-driven key bindings, raw key events (with optional vanilla blocking), and an optional handshake (e.g. requiring the mod on dedicated servers).
• :protocol module: channel IDs, protocol version, capability bits, kick reasons, and ProtocolMessages encode/decode without a Minecraft dependency.
• Fabric mod: custom payloads (s2c_hello, c2s_client_info, s2c_bindings, c2s_key_action), Fabric Networking registration, client API (KrepApi / listeners), mixin integration for keyboard input.
• Reference :paper-plugin: plugin messages, handshake flow, sample config.yml.
• Docs in-repo/wiki: protocol, client API, Paper plugin (including security notes for c2s_key_action).

Compatibility

• Minecraft (Fabric): declared support for >=1.21.4 through <=1.21.11; Loom build targets 1.21.11 (Yarn) with Java 21 bytecode for typical runtimes.
• Key bindings: runtime compatibility between the older API (category as String) and 1.21.11+ (KeyBinding.Category via Identifier).
• Networking / Minecraft 1.21.11: updates for current Yarn (e.g. RegistryByteBuf, PacketCodec.ofStatic, readString/writeString, CustomPayload.Id for registration, MinecraftServer.isDedicated()).

Notes

• Install a Fabric API build that matches the Minecraft version.

KrepAPI (for developers)

• Build version (Fabric mod release / c2s_client_info.modVersion, gradle.properties → mod_version): 1.0.0
• Wire protocol version (KrepapiProtocolVersion.CURRENT, protocolVersion in s2c_hello / c2s_client_info): 1 — increment only when the binary packet layout or semantics change
