Versions and Compatibility

The 2.0 line of GeoMesa will follow Semantic Versioning. It will continue to offer data compatibility, in that data written with older versions will still be readable. It will also offer API compatibility, in that any 2.x client code will be able to communicate with any 2.x server code, although using new features that are added may require updating both client and server code.

Known Incompatibilities

Due to the switch from Joda time to java.time, the date format strings used by the GeoMesa converter library have changed slightly. In particular, 'YYYY' will generally need to be replaced with 'yyyy'. See the upgrade guide for details.

Upgrading

GeoMesa 2.x supports upgrade in place from previous versions, by updating the GeoMesa JAR versions. Ensure that JARs are updated in all clients and servers.  See the upgrade guide for information on changes that may affect you after the update.
