NilLoaderSDK API

[3.0.0] - 2026-08-05

Added

• Added agaricusb/MinecraftRemapping as an external Git submodule configuration at tools/MinecraftRemapping, pinned by the bootstrap scripts to 8ca7ba25dfd67eae43b3c73d02603ff6c085a6d7.
• Added a Java 8-compatible SRG/CSRG mapping API: SrgMappingSet and SrgMappings.
• Added MappingToolMain with inspect, reverse, chain, lookup, list-submodule, and import-submodule commands, plus a standalone mapping-tool JAR that contains no mapping data.
• Added Gradle mappingTool and prepareRemapping tasks for local mapping workflows.
• Added MAPPINGS.md documenting mapping-source policy and local-only import behavior.
• Added cross-platform Gradle launcher JVM discovery for Linux/macOS and Windows. JDK 21 and 17 are preferred automatically so a system-wide Java 25 does not break Gradle 8.8.
• Added GitHub Actions build.yml for push/pull-request builds and tests on Ubuntu/Windows with JDK 17/21.
• Added GitHub Actions release.yml for v* tags. Releases are created only after build/tests succeed, include JARs plus SHA-256 checksums, and use the matching CHANGE.md section as the release body.
• Added release helper scripts that verify tag/project version consistency and extract one changelog section.

Changed

• Bumped the SDK and metadata version to 3.0.0.
• Java compilation now targets Java 8 with --release 8 while Gradle itself runs on a supported modern launcher JDK; a dedicated local JDK 8 installation is no longer required for normal builds.
• Complete mapping collections are no longer shipped in the project ZIP/release tree. .remapping/ remains gitignored and is treated as developer-supplied local build input.
• GitHub release responsibilities were separated from normal commit CI: build.yml only validates commits/PRs, while release.yml owns tagged releases.

Fixed

• Fixed Gradle 8.8 startup failing under Java 25 with Unsupported class file major version 69 by selecting a compatible installed launcher JDK before Gradle starts.
• Fixed old mapping workflows relying on copied 100+ MB mapping trees by replacing them with explicit local import tooling and an external submodule reference.
• Mapping parsing now reports conflicting entries instead of silently replacing them, mapping composition keeps method descriptors namespace-correct, and CSRG member resolution no longer depends on class-entry order.
