    • A IndexUpgrader tool that let’s you upgrade your index to the new format
    • NRTCachingDirectory implementation which caches small segments in RAM
    • A new Collector implementation, CachingCollector, which helps developing functionalities which requires more than one pass
  2. Solr
    • Ability to specify overwrite and commitWithin as request parameters when using the JSON update format
    • Improvements to UIMA integration and Carrot2 library integration
    • Performance improvements of highlighting functionality
    • Jar file containing test-framework
    • Improvements from Apache Lucene 3.2
