[2.0.0] - 2026-04-08

Added

• Introduced KDL support as a first-class metadata layer in 2.0.0.
  • Prior to 2.0.0, mods relied on NilLoader CSS metadata only (*.nilmod.css).
  • 2.0.0 adds SDK KDL metadata (*.nilsdkmod.kdl) and runtime bridge integration.
• Introduced a general-purpose KDL toolkit for broad SDK usage (not metadata-only):
  • KdlParser, KdlWriter
  • KdlDocument, KdlNode, KdlValue, KdlParseException
  • Can be used by any system/module that needs KDL parsing/serialization.
• NilLoaderHelper convenience APIs for easier multi-mod integration and diagnostics:
  • isAllModsLoaded(String...)
  • getFirstLoadedMod(String...)
  • getEntrypoints(String)
  • hasEntrypoint(String, String)
  • getModsWithEntrypoint(String)
  • hasMissingRequiredMods(String)
  • getMissingRequiredModsForLoadedMods()
  • getModsRequiring(String)
• Forge/Fabric-like event architecture for easier mod development:
  • Global SDK access point: NilLoaderSDK
  • Event primitives: Event, CancellableEvent, EventPriority, SubscribeEvent
  • Central EventBus with:
    • annotation listener registration (@SubscribeEvent)
    • typed callback registration (listen style)
    • cancellation-aware dispatch flow
  • Lifecycle events:
    • PreEntrypointDispatchEvent (cancellable)
    • PhaseEvent
    • PostEntrypointDispatchEvent
  • Entrypoint dispatcher now emits lifecycle events around phase execution.
  • NilModBase now includes convenience methods to register/post/listen events.
• SDK KDL metadata schema expanded with richer mod info fields:
  • modurl
  • sourceurl
  • license
  • credits (multi-value)

Changed

• Bumped SDK version to 2.0.0 in build and metadata resources.
• NilMetadataBridge now parses .nilsdkmod.kdl via shared KDL parser (KdlParser) instead of manual string parsing for better compatibility.
• KDL metadata merge now supports both section blocks (nilmod {}, entrypoints {}) and top-level fallback keys (name, description, authors, version, entrypoints.<phase>).

Fixed

• Removed inconsistent changelog carry-over for 1.0.4 under 2.0.0.

Notes

• New helper methods are Java 8 compatible and return immutable collections where applicable.
• Focus of this update is DX (developer experience): reduce repetitive NilLoader metadata and dependency-check boilerplate in mods.
• Backward compatibility remains intact: CSS metadata stays primary, and KDL is additive for SDK-aware features.
