GeoMesa 1.3 Milestone Releases - GeoMesa 1.3 will release a series of milestone releases which are not designed to be interoperable with each other from an API point of view. They will, however, still provide data compatibility. They are intended to provide new functionality to early adopters. When upgrading to future release candidates, make sure to upgrade all GeoMesa JARs in your environment (i.e. GeoServer plugin, distributed runtime, and ingest JARs) to the same matching versions.
