The Kamakura Release is version 2.2 (a minor release on the second major release - Ireland - made during the summer of 2021). It is therefore backward compatible with Ireland (as well as Jakarta). It is the 10^th overall community release of EdgeX Foundry.

Release Major Themes

Metrics Telemetry Collection - micro service metrics/telemetry collection capability - making it easier for adopters to monitor the health and status of the EdgeX services with some collection examples added to core data (example: number of events/readings persisted)
Delayed Start Services -addition and changes of security services to allow for EdgeX services to be added and started anytime and still receive security tokens without the need for a restart of the platform
New camera device services - allowing improved capabilities to command, control and interface with ONVIF and USB cameras
LLRP/RFID device and application services – making it easier to consume and use RFID collected data
V2 of the EdgeX CLI - allowing CLI calls of any of the EdgeX REST APIs, and compatibility with EdgeX 2.0 while also adding tab completion, use of the registry to provide configuration, and improved output results.
