v0.3.0

Highlights

• New API: BrkgaMpIpr.getLastRunBestChromosome() — returns the historical best
  solution of the last run(), the overall incumbent. Unlike getBestChromosome()
  (the current-population best), it survives any shake/reset triggered during the
  run, and its fitness equals the AlgorithmStatus.bestFitness that run() returns.
  Backed by the new native symbol brkga_get_last_status_best_chromosome.

Install

<dependency>
    <groupId>io.github.codeurjc</groupId>
    <artifactId>brkga-mp-ipr-java</artifactId>
    <version>0.3.0</version>
</dependency>

Upgrade note

The wrapper bundles precompiled Linux x86-64 native binaries, so no C++ toolchain is
needed. If you supply your own native library via -Dbrkga.bridge.dir, rebuild it from
the 0.3.0 sources — a 0.2.0 .so lacks brkga_get_last_status_best_chromosome and the
wrapper will fail to link it.

Also included

• Fixed inverted @return javadoc on addNewSolutionObserver (returning true keeps
  the optimization running; false stops it).

v0.2.0 — Require Java 25

Java edition of BRKGA-MP-IPR, now targeting Java 25.

Highlights

• Requires JDK 25 or newer (previously JDK 22). The library is compiled with
  --release 25, so this is a breaking change for consumers still on JDK 22–24.
  The Foreign Function & Memory API it relies on remains stable (non-preview)
  since JDK 22.

• Published to Maven Central as 0.2.0:

  <dependency>
      <groupId>io.github.codeurjc</groupId>
      <artifactId>brkga-mp-ipr-java</artifactId>
      <version>0.2.0</version>
  </dependency>

  Run with native access enabled: java --enable-native-access=ALL-UNNAMED ....
  Linux x86-64 native binaries are bundled, so no C++ toolchain is needed to
  use the library.

Under the hood

• Toolchain moved to JDK 25 across CI, Dockerfile.dev and the dev container.
• Pinned maven-compiler-plugin (3.13.0) in both POMs so the release level is
  honoured regardless of the local Maven version.
• Publishing fixes: bumped central-publishing-maven-plugin to 0.11.0 and
  enabled automatic release on Sonatype Central.
