# v1.5.0

* Enhancement

  * [Add `st_distancesphere/2`](https://github.com/bryanjos/geo/pull/69)



# v1.4.1

* Fixes

  * [Updated ecto related documentation on Geo module](https://github.com/bryanjos/geo/pull/66)



# v1.4.0

* Enhancements

  * [Add `st_dwithin_in_meters\3`](https://github.com/bryanjos/geo/pull/64)

  * [Make sure an srid of 0 does not show srid in WKT](https://github.com/bryanjos/geo/pull/63)

  * [Add types PointZ, PointM and PointZM](https://github.com/bryanjos/geo/pull/56)



# v1.3.1

* Enhancements

  * Relax Poison dependency requirement



# v1.3.0

* Enhancements

  * [Support new Postgrex 0.13 Extension API](https://github.com/bryanjos/geo/pull/53)



* Breaking

  * Now only supports Postgrex 0.13+

  * Now only supports Ecto 2.1+



# v1.2.1

* Enhancements

  * [add st_transform](https://github.com/bryanjos/geo/pull/51)



# v1.2

* Enhancements

  * [add st_distance_sphere](https://github.com/bryanjos/geo/pull/49)



# v1.1.2

* Bug Fixes

  * WKBs that are GeometryCollections with one element should now properly decode



# v1.1.1

* Enhancements

  * Added `Geo.JSON.EncodeError` and `Geo.JSON.DecodeError` thrown whenever `Geo.JSON.encode` or `Geo.JSON.decode` are given invalid data





# v1.1

* Enhancements

  * Add Geo.Geometry custom Ecto type to allow multiple geometries in a single field



# v1.0.6

* Enhancements

  * Fixed warnings that appeared in Elixir 1.3



# v1.0.5

* Enhancements

  * Update to allow use with Ecto 2.0



# v1.0.4

* Enhancements

  * Ecto.Type: matching on geojson properties so that Ecto.DataType can be used by users



# v1.0.3

* Enhancements

  * Updated dependencies to allow for using ecto 2.0 release candidate versions



# v1.0.2

* Enhancements

  * Updated dependencies to allow for using ecto 2.0 beta versions



# v1.0.1

* Enhancements

  * Updated Postgrex and Poison optional dependencies



# v1.0.0



# v0.18.0

* Enhancements

  * Made Postgrex, Ecto, and Poison optional dependencies



# v0.17.0

* Breaking

  * Geo.JSON.encode and Geo.JSON.decode now do not do any JSON parsing at all and

    instead work on a map representation of GeoJSON. All JSON encoding and decoding

    must be done before or after calling those functions.



# v0.16.1

* Enhancements

  * Made Postgrex a required dependency



# v0.16.0

* Enhancements

  * Updated to Ecto 1.0



# v0.15.2

* Enhancements

  * Added an `opts` parameter to `Geo.JSON.encode` to allow for skipping JSON encoding



# v0.15.1

* Enhancements

  * Fixed st_dwithin macro



# v0.15.0

* Enhancements

  * Updated cast function on structs to handle maps and strings

  * Now reading the srid from geo json



# v0.14.0

* Enhancements

  * Basic Support for Geography datatype



# v0.13.0



* Enhancements

  * Added PostGIS function macros for use in Ecto Queries. Currently only the OpenGIS ones



* Breaking

  * `Geo.PostGIS` is now `Geo.PostGIS.Extension`

  * Changed from Jazz to Poison for JSON encoding and decoding



# v0.12.0



* Enhancements

  * Geo.PostGIS is now a Postgrex Extension

  * Updated to work with latest version of Ecto



# v0.11.2



* Bug fixes

  * Correctly decoding WKB strings that caused invalid geometries to be produced when there is one element in a multi geometry



# v0.11.1



* Bug fixes

  * Fixed bug when decoding multi geometry wkb with one geometry inside would cause a crash



# v0.11.0



* Enhancements

  * Created structs for the supported geospatial types (Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, GeometryCollection)

  * GeoJson module will encode the srid as a crs property if an srid exists



* Backwards incompatible changes

  * Removed the Geometry struct. Use one of the geometry type structs instead

  * The base coordinate pairs are now tuples ({0,0} instead of [0,0])
