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). Documentation links:
  • https://docs.edgexfoundry.org/2.2/microservices/general/#service-metrics

  • https://docs.edgexfoundry.org/2.2/microservices/application/AdvancedTopics/#custom-application-service-metrics
  • https://docs.edgexfoundry.org/2.2/microservices/application/AppServiceConfigurable/#metrics-influxdb
• 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. The previous Camera Device Service is now deprecated
• 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.

• Added linting (the automated checking of source code for programmatic, stylistic and security issues) part of the regular build checks and tests on all service pull requests
• Formalized release and planning meeting schedule
• Better tracking of project decisions through new GitHub project boards
