Boron release is the fifth release of the OVSDB project. Main focus for this release was to provide the features and improvement that is expected from any production level device plugin. Following are the few main feature that OVSDB project delivered in it's Boron release
Release Deliverables
- Performance and scalability improvements
- Migrated from Config Subsystem to Blueprints. It will help with the upgrade of the plugin from Beryllium to Boron.
- Reconciliation of user stored configuration on switch disconnection or controller reboot.
- Improvement in device connection management
- Docker based integration system environment
- Support for auto attach table and ifindex (Interface table)
- Support for Interface Bidirectional Forwarding Detection (BFD).
- Improvement in OVSDB Qos and Queue support
- Code quality, stability and usability
- Logging improvements
Target Environment
For Execution
Same as the usual JRE requirements for OpenDaylight (JDK 1.8)
For Development
Same as the usual JDK and Maven requirements for OpenDaylight (JDK 1.8, Maven 3.3.9)
Known Issues and Limitations
- Hardware Vtep currently don't support full reconciliation. It only support connection reconciliation only.
- Support for auto attach table is currently experimental.

Migration from Previous Releases
OpenStack Network Virtualization (widely known as 'NetVirt') was part of the OVSDB project prior to the Boron release. Given it's wider scope, this functionality was moved to it's own new project (named 'netvirt'). For more details about this migration, please refer to the netvirt projects page.
Compatibility with Previous Releases
Yes, compatible with previous releases.
Deprecated, End of Lifed, and/or Retired Features/APIs
- Old OVSDB QoS and Queue models were deprecated in the Boron release and new models were introduced. This yang file contains details of the deprecated model (look for 'status deprecated') and newly introduced models as well.
