## v3.0.0

* Add

  * `Geo.WKT.encode!`
  * `Geo.WKT.decode!`
  * `Geo.WKB.encode!`
  * `Geo.WKB.decode!`
  * `Geo.JSON.encode!`
  * `Geo.JSON.decode!`

* Enhancement

  * Geometry struct now have a `properties` field. This is used to convert GeoJSON properties

* Breaking

  * `Geo.WKT.encode` now returns either `{:ok, binary}` or `{:error, exception}`
  * `Geo.WKT.decode` now returns either `{:ok, geometry}` or `{:error, exception}`
  * `Geo.WKB.encode` now returns either `{:ok, binary}` or `{:error, exception}`
  * `Geo.WKB.decode` now returns either `{:ok, geometry}` or `{:error, exception}`
  * `Geo.JSON.encode` now returns either `{:ok, map}` or `{:error, exception}`
  * `Geo.JSON.decode` now returns either `{:ok, geom}` or `{:error, exception}`
  * All Ecto.Type behaviour implementations were removed. This may not effect too many people, but it was moved to the [geo_postgis](https://github.com/bryanjos/geo_postgis) package

# 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
