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 (Beta released)-  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) and App services (MessagesReceived, PipelineMessagesProcessed and PipelineMessageProcessingTime).

• 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
