Lucene 7.6.0 Release Highlights:

• Index sorting corruption due to numeric overflow has been fixed. Indices affected by this bug can be detected by running the CheckIndex command on a 7.6+ release distribution.
• Better tessellation processing of Polygons including graceful exceptions for detecting invalid shapes.
• Points codec now supports selective indexing; the ability to designate dimensions as as “data only” dimensions that do not affect construction of the index.
• New Simple WKT Shape Parser builds lucene geometries (polygons, lines, rectangles) from WKT format.
• New LatLonShapeLineQuery queries indexed shapes with arbitrary lines.
• analyzeGraphPhrase query builder creates one phrase query per finite strings in the graph based on slop parameter.
• Performance in PerFieldMergeState#FilterFieldInfos has been improved from O(N) to O(1) lookup time.
