CHANGES

v0.6.0 (1 Nov 2022)
- Added a basic command-line interface for standalone use.
- Freezing off Lucene 8.11.2 into internal code so the dependency is no
  longer required. It should now be possible to use this library if you're
  stuck on an earlier major version of Lucene.
- Support versions up to Lucene 8.11.2.
- Build modernisation:
    - Updated to Java 11.
    - Changed build system to Gradle.
    - Changed JavaScript engine (used to generate test data) to GraalVM.
- Commented out Lucene 5 code which was using illegal reflective access
  to unmap buffers.
