- == Lucene 7.6.0 Release Highlights: ==
+ == Lucene 7.7.0 Release Highlights: ==
  
  === Bug Fixes ===
-  * 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.
+ 
+ * Fix LatLonShape WITHIN queries that fail with Multiple search Polygons that share the dateline.
+ * LatLonShape's within and disjoint queries can return false positives with indexed multi-shapes.
  
  === Improvements ===
-  * 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.
-  * Performance in PerFieldMergeState#FilterFieldInfos has been improved from O(N) to O(1) lookup time.
  
+ * ExitableDirectoryReader may now time out queries that run on points such as range queries or geo queries.
+ * LUCENE-8527: StandardTokenizer and UAX29URLEmailTokenizer now support Unicode 9.0,
+   and provide Unicode UTS#51 v11.0 Emoji tokenization with the "<EMOJI>" token type.
+ * TopFieldCollector can now early-terminates queries when sorting by SortField.DOC.
+ * Speed up merging segments of points with data dimensions by only sorting on the indexed dimensions.
+ * The KoreanTokenizer no longer splits unknown words on combining diacritics and detects script boundaries more accurately with Character#UnicodeScript#of.
+ * Change LatLonShape encoding to use 4 bytes Per Dimension.
+ * BufferedUpdates now uses an optimized storage for buffering docvalues updates that
+   can safe up to 80% of the heap used compared to the previous implementation and uses non-object
+   based datastructures. (Simon Willnauer, Mike McCandless, Shai Erera, Adrien Grand)
+ * Moved to the default accepted overhead ratio for packet ints in DocValuesFieldUpdates yields an up-to 4x performance improvement when applying doc values updates.
+ * Doc-value updates get applied faster by sorting with quicksort, rather than an in-place mergesort, which needs to perform fewer swaps.
+ * Decrease I/O pressure when merging high dimensional points.
