0.7.5

Enhancements

• #39 remove dependency on guava (>2MB) by replacing MinMaxPriorityQueue with BoundedPriorityQueue built on backported java 8 PriorityQueue and using guava-mini (11KB)
• upgrade to rxjava 1.1.1
• use simplified min and max that doesn't do NaN checks
• simplify Rectangle.intersects method

Performance improvements

• A combination of rtree changes and rxjava improvements have bumped up many performance benchmarks by 10 to 50 %
• improvements in performance mean that your data set may now perform better using different RTree parameters. For instance maxChildren=10 now performs better than maxChildren=4 for the Greek Earthquake data set.

0.7.4

• fixed hang bug with RTree.nearest() #38
• decrease memory usage of ListPair by making a Float field a float field
• RTree.size should be final field

0.7.2

• #29 fix for Visualizer so geometries with an mbr with zero width or height are visible

0.7.1

• #34 minimum bounding rectangle not calculated correctly if max x and y values of rectangle were negative. As a consequence the mbr was sometimes bigger than it needed to be. This is an important bug fix for users with lat/long geometries for instance.

0.7

• #31, #32 add Line as Geometry type (jts-core dependency required)
• #35 add RTree.mbr() method

0.6.8

• Fix for #28 - Geometries.normalizeLongitude(-180) should return -180.
• added javadoc

0.6.4

• update to rxjava 1.0.12
• ensure R*-tree conforms to specification with optimal splits #26

0.6.3

• renamed Geometries.rectangeLatLon to rectangleGeographic and Geometries.pointLatLon to Geometries.pointGeographic

0.6.2

• upgrade rxjava dependency to 1.0.10
• add Geometries.rectangleLatLon(...) and Geometries.pointLatLon(...) factory methods that normalize longitude values to enable spatial searches using lat long coordinates

0.6.1

• don't touch volatile stack in requestSome() loop to avoid unnecessary memory synchronizations (~2x search throughput improvement on backpressure path)
• fix possible race condition where two requests can concurrently initiate fast path (double emissions)
