+|0.5.3| **Bug fix:** Fix [Issue #69](https://github.com/DataSystemsLab/GeoSpark/issues/69): Now, if two objects have the same coordinates but different non-spatial attributes (UserData), GeoSpark treats them as different objects.|
 |0.5.2| **Bug fix:** Fix [Issue #58](https://github.com/DataSystemsLab/GeoSpark/issues/58) and [Issue #60](https://github.com/DataSystemsLab/GeoSpark/issues/60); **Performance enhancement:**: (1) Deprecate all old Spatial RDD constructors. See the JavaDoc [here](http://www.public.asu.edu/~jiayu2/geospark/javadoc/0.5.2/). (2) Recommend the new SRDD constructors which take an additional RDD storage level and automatically cache rawSpatialRDD to accelerate internal SRDD analyze step|
 |0.5.1| **Bug fix:** (1) GeoSpark: Fix inaccurate KNN result when K is large (2) GeoSpark: Replace incompatible Spark API call [Issue #55](https://github.com/DataSystemsLab/GeoSpark/issues/55); (3) Babylon: Remove JPG output format temporarily due to the lack of OpenJDK support|
 | 0.5.0| **Major updates:** We are pleased to announce the initial version of [Babylon](https://github.com/DataSystemsLab/GeoSpark/tree/master/src/main/java/org/datasyslab/babylon) a large-scale in-memory geospatial visualization system extending GeoSpark. Babylon and GeoSpark are integrated together. You can just import GeoSpark and enjoy! More details are available here: [Babylon GeoSpatial Visualization](https://github.com/DataSystemsLab/GeoSpark/tree/master/src/main/java/org/datasyslab/babylon)|
