  Lucene 6.3.0 Release Highlights:
  
  New features
-   * A brand new "!UnifiedHighlighter" derivative of the !PostingsHighlighter that can consume offsets from postings, term vectors, or analysis.  It can highlight phrases as accurately as the standard Highlighter. Light term vectors can be used with offsets in postings for fast wildcard (!MultiTermQuery) highlighting.
-   * !SimpleQueryParser now parses '*' to !MatchAllDocsQuery
-   * !FuzzyQuery now matches all terms within the specified edit distance, even if they are short terms
  
  Optimizations
-   * Points do not store the implicit split dimension in the 1-dimension case. This saves between 6% memory for the largest types such an !InetAddressPoint to 33% for the smaller types such as !HalfFloatPoint.
  
  Along with numerous bug fixes.
