0.5.10 and prior

0.5.10

• Upgraded to shapeless 2.3.2
• Fixed #36, #37

0.5.9

• Ported to sbt 1.0.3
• Added sbt-generated astraea.spark.rasterframes.RFBuildInfo
• Fixed bug in computing aggMean when one or more tiles are null
• Deprecated rfIinit in favor of SparkSession.withRasterFrames or SQLContext.withRasterFrames extension methods

0.5.8

• Upgraded to GeoTrellis 1.2.0-RC1
• Added REPLsent-based tour of RasterFrames
• Moved Giter8 template to separate repository s22s/raster-frames.g8 due to sbt limitations
• Updated Getting Started to reference new Giter8 repo
• Changed SQL function name rf_stats and rf_histogram to rf_aggStats and rf_aggHistogram
  for consistency with DataFrames API

0.5.7

• Created faster implementation of aggregate statistics.
• Fixed bug in deserialization of TileUDTs originating from ConstantTiles
• Fixed bug in serialization of NoDataFilter within SparkML pipeline
• Refactoring of UDF organization
• Various documentation tweaks and updates
• Added Giter8 template

0.5.6

• TileUDFs are encoded using directly into Catalyst--without Kryo--resulting in an insane
  decrease in serialization time for small tiles (int8, <= 128²), and pretty awesome speedup for
  all other cell types other than float32 (marginal slowing). While not measured, memory
  footprint is expected to have gone down.

0.5.5

• aggStats and tileMean functions rewritten to compute simple statistics directly rather than using StreamingHistogram
• tileHistogramDouble and tileStatsDouble were replaced by tileHistogram and tileStats
• Added tileSum, tileMin and tileMax functions
• Added aggMean, aggDataCells and aggNoDataCells aggregate functions.
• Added localAggDataCells and localAggNoDataCells cell-local (tile generating) fuctions
• Added tileToArray and arrayToTile
• Overflow fix in LocalStatsAggregateFunction
