## [0.5] - 2017-02-21

### Added

* Bind to expm1
* Add bindings to dayofmonth, current_timestamp and current_date.
* Add support for the dataframe condition expressions
* Add bindings to withColumnRenamed, columns, printSchema, Column.expr.
* Bind DataFrame distinct.
* Add bindings for log and log1p for Columns.
* Add binding to Column.cast.
* Add bindings getList and array for columns.
* Add bindings: schema for rows, Metadata type, javaRDD, range, Row
  getters and constructors, StrucType constructors, createDataFrame,
  more DataType bindings.

### Changed

* Prevent Haskell exceptions from escaping apply.
* Update sparkle to work with latest jni which uses ForeignPtr
  for java references.
* Move StructType and friends to modules StructField, DataType and Metadata.
* Rename createRow, rowGet, rowSize, joinPairRDD to have the same names
  as the java methods.

## [0.4]

### Added

* Support for reading/writing Parquet files.
* More `RDD` method bindings: `repartition`, `treeAggregate`,
  `binaryRecords`, `aggregateByKey`, `mapPartitions`, `mapPartitionsWithIndex`.
* More complete `DataFrame` support.
* Intero support.
* `stack ghci` support.
* Support Template Haskell splices and `ANN` annotations that use
  sparkle code.

### Changed 

### Fixed

* More reliable initialization of embedded shared library.
* Cleanup temporary files properly.

## [0.3] - 2016-12-27

### Added

* Dockerfile to build sparkle.
* Compatibility with singletons-2.2.
* Add the identity `Reify`/`Reflect` instances.
* Change JNI bindings to use new `JNI.String` type, instead of
  `ByteString`. This new type guarantees the invariants required by
  the JNI API (null-termination in particular).

### Changed

* Remove `Reify`/`Reflect` instances for `Int`. Only instances for
  sized types remain.

### Fixed

* Fix type in `Reify Int` making it incorrect.

## [0.2.0] - 2016-12-13

### Added

* New binding: `getOrCreateSQLContext`.

### Changed

* `getOrCreate` renamed to `getOrCreateSparkContext`.

## [0.1.0.1] - 2016-06-12

### Added

* More bindings to more `call*Method` JNI functions.

### Changed

* Use `getOrCreate` to get `SparkContext`.

## [0.1.0] - 2016-04-25

* Initial release
