GeoMesa 1.3.0-m0 is the first milestone for our GeoMesa 1.3 line and includes 40+ Fixes and Improvements
Versions & Compatibility
1.2 Maintenance Releases - GeoMesa will continue to cut releases on the 1.2.x line of GeoMesa targeted at bugfixes and stability improvements on existing Accumulo 1.6 installations. Features can be back-ported from 1.3 to 1.2 but in general new functionality will be targeted to 1.3 in order to balance stability with innovation.
GeoMesa 1.3 Compatibility- The 1.3 line of GeoMesa will be a stable line of GeoMesa releases that is aimed at providing as much API compatibility as possible. Our goal is to provide minor version interoperability meaning that any 1.3.x client or server code can talk to each other. This compatibility feature may be completely available until the 1.3.0 final release as we will be working on it during the milestone and release candidate phases.
GeoMesa 1.2 Compatibility- The 1.2 line of GeoMesa releases provides what we have termed data compatibility meaning that data ingested with previous versions can still be used with new versions of the GeoMesa jars. For example, data ingested with 1.2.0 can be read and written by 1.2.6. This compatibility required that the geoserver plugin, tools, and distributed runtime jars all had to match in their minor version numbers.
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 when upgrading to future release candidates make sure to upgrade all geomesa in your environment (e.g. geoserver, distributed runtime, ingest) to the same matching versions

- Kafka 10 - requires compilation
Allow Add/Update/Removal of Indexes
- Users can now add, update and remove specific types of indexes (e.g. Z2, Z3, XZ2, XZ3, etc) for feature types within a catalog
Upgrading
