Summary

  • Bump Elasticsearch 9.3.4 → 9.4.0 across build.sbt, docker/Dockerfile, docs/pages/installation.md, version, and client-python/requirements.txt
  • Bump Lucene 10.3.2 → 10.4.0 (bundled with ES 9.4.0)
  • ES API breakage:
    • FieldMapper.Builder.contentType() is now abstract — implemented in VectorMapper.Builder
    • AbstractQueryBuilder.doToQuery now takes a MaxClauseCountQueryVisitor — updated ElasticsearchQueryBuilder and IndexedVectorQueryBuilder
  • Lucene codec rename: Lucene103CodecLucene104Codec in HashingQueryPerformanceSuite
  • Elastic4s stays at 9.3.0 (no 9.4.x published yet; 9.3.0's minor ≤ ES 9.4 per upgrade rule)

Test plan

  • task jvmCompile
  • task jvmUnitTest
  • CI integration tests pass
