Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning from version 5.0.0 onward. Pre-fork releases (1.x–4.2.0) were authored by kherud/java-llama.cpp.

Unreleased

Added

  • CODE_OF_CONDUCT.md (Contributor Covenant 2.0).
  • docs/RELEASE.md capturing the maintainer-facing release procedure (moved out of CHANGELOG).
  • OpenSSF Best Practices badge (project 12862) on README.

Changed

  • Unified CONTRIBUTING.md and SECURITY.md structure with sibling repositories in the project family.
  • Reconciled Java baseline to 11+ across pom.xml, README badge, CLAUDE.md, and CONTRIBUTING.md.
  • README license badge corrected from "Apache 2.0" to "MIT" (matches LICENSE file and pom.xml).
  • pom.xml SCM URL: tree/master → tree/main (default branch renamed).
  • Upgraded llama.cpp from b9151 to b9172.

Added

  • Reasoning-budget tests (Qwen3-0.6B).

5.0.1 - 2026-05-14

Added

  • InferenceParameters.setContinueFinalMessage(boolean) for the vLLM/transformers-compatible prefill-assistant heuristic (llama.cpp b9134+).
  • Tests for setContinueFinalMessage.
  • Comprehensive Javadoc on public APIs (PR #129).
  • Maven Central badge on README (PR #130).

Changed

  • Bumped project version to 5.0.1-SNAPSHOT (PR #127), then released as 5.0.1 (PR #135).
  • Refactored GitHub release workflow to parallelise snapshot and release jobs (PR #128).
  • Removed snapshot build documentation and badge (PR #131).
  • Upgraded Windows CI to windows-2025 with Visual Studio 2026 (PR #132).
  • Switched Windows MSVC runtime from dynamic (/MD) to static (/MT) to eliminate the msvcp140.dll runtime dependency (PR #133).
  • Upgraded llama.cpp from b9106 to b9134 (PR #134), then to b9150 (PR #136), then to b9151 (PR #139).
  • Refactored CI workflow with explicit snapshot/tag check gates (PR #137).
  • Removed setCtxSizeDraft() — the underlying CLI flag was deleted upstream in llama.cpp b9106.

Fixed

  • fix(publish): quoted gate job names to avoid YAML colon-in-scalar parse errors (PR #138).
  • Release routing in the publish workflow now correctly distinguishes snapshot vs. tag pushes.

5.0.0 - 2026-05-11

First release of the fork under the net.ladenthin:llama Maven coordinates. ~100 merged pull requests since baseline 49be664 (the last pre-fork upstream commit).

Added

  • First publish to Maven Central under net.ladenthin:llama.
  • Pre-built native libraries for Linux (x86-64, aarch64), macOS (x86-64, arm64), and Windows (x86-64, x86).
  • Java API surface: LlamaModel, ModelParameters, InferenceParameters, LlamaIterator / LlamaIterable for streaming, chat completion (chatComplete, generateChat, chatCompleteText), embeddings, reranking, infilling, raw JSON endpoint handlers, slot management (saveSlot, restoreSlot, eraseSlot), and getModelMeta().
  • chatComplete() for OpenAI-compatible chat completions, re-implemented from scratch based on a patch by @vaiju1981 (PR #61; see docs/history/CHAT_INTEGRATION_SUMMARY.md).
  • mmproj, reasoning-budget, sigma, and sleep-idle parameters added to ModelParameters.
  • JaCoCo code-coverage reporting integrated with Coveralls and Codecov (PR #124).
  • CodeQL static-analysis workflow on push, PR, and a weekly schedule.
  • Automated Claude Code review workflow on pull requests.
  • Dependabot for Maven and GitHub Actions dependency updates.
  • Automatic snapshot release workflow on main push (PR #105) publishing to the Sonatype Central snapshot repository.
  • CUDA, Metal, and Vulkan build support via local CMake build.
  • Android integration documented in README.
  • All system properties (net.ladenthin.llama.*) and LogLevel values documented.
  • CLAUDE.md maintainer guide covering upstream upgrade procedure and the b5022→b9172 breaking-change table.

Changed

  • Migrated Maven group and artifact from de.kherud:java-llama.cpp to net.ladenthin:llama (PR #101).
  • Migrated Maven Central publishing from OSSRH (Legacy) to the Sonatype Central Publisher Portal.
  • Deleted the hand-ported server.hpp fork (~3,780 lines) and linked the upstream llama.cpp server source files directly into jllama. ~4,100 C++ lines removed in total; future upstream upgrades become a CMake version bump. The Java API is unchanged. See docs/history/REFACTORING.md.
  • Compiled upstream server-context / queue / task / models directly into jllama (PR #96).
  • Unified CI into a single publish.yml workflow with cross-compilation, testing, coverage, and release stages.
  • Upgraded CUDA from 12.1 to 13.2 (PR #50).
  • Upgraded llama.cpp from b8913 through b9106 across multiple incremental upgrades.
  • setDraftMax / setDraftMin now emit the canonical --spec-draft-n-max / --spec-draft-n-min flags (llama.cpp b9016 removed the old aliases).
  • Bumped CI GitHub Actions: actions/checkout v4 → v6, actions/upload-artifact v6 → v7, actions/download-artifact v6 → v8, codeql-action v3 → v4.

Fixed

  • Javadoc warnings resolved across the public API by adding missing comments.
  • cache_idle_slots slot-parameter handling aligned with the upstream rename (b8841 → b8854).

Pre-fork history (kherud/java-llama.cpp 1.x–4.2.0)

Releases 1.1.1 through 4.2.0 were authored by @kherud on the upstream repository. The full upstream release notes are at https://github.com/kherud/java-llama.cpp/releases. The fork's baseline is upstream commit 49be664 (tagged v4.2.0, 2025-06-20).
