GeoMesa 1.3.0-m1 is the second milestone for our GeoMesa 1.3 line and includes 35+ Fixes and Improvements

Changes

  • A script for automatically installing and uninstalling GeoMesa plugins in GeoServer has been added to each distribution.
  • The Kafka 0.9 and 0.10 distributions are now included in the default build, and binary distributions are available.
  • A new optional caching implementation for Kafka consumers based on CQEngine has been added.
  • Documentation has been updated to reflect the distribution architecture changes in the 1.3.0-mX milestone series.

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 for existing Accumulo 1.6+ installations. Features may be backported 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 interoperate. This compatibility feature will not be available during the 1.3.0 milestone release phase.

...

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.
