Lucene 6.2.0 Release Highlights:

New features
  * The CREATE_NEW flag is passed when creating a file to ensure Lucene is really write-once
  * Index numeric ranges (min and max value in a single field) and search by overlapping range
  * IndexWriter methods return a sequence number indicating effective order of operations across threads
  * UkrainianMorfologikAnalyzer is a new dictionary based analyzer for the Ukrainian language
  * The Polygon class can now be created from a GeoJSON string
  * Compound file creation now verifies checksum of its component files
  * Index time sorting is now a core feature, and supports dimensional points
  * StandardAnalyzer is moved to core and is the default analyzer
  * MatchNoDocsQuery now includes the reason it was created
  * QueryParser can now be told to not pre-split on whitespace
  * MMapDirectory tries harder to prevent SIGSEGV if buggy code tries to execute
    searches after the index was closed, but it's still best effort
  * MMapDirectory no longer allocates weak references to ease garbage collection

Optimizations
  * Conjunction (MUST, FILTER) queries are faster
  * Dimensional points have much faster (~40%) flush time and use less space in the index

Along with numerous bug fixes.
