Now that the V2 protocol is out from 8.3 on, the V1 will not be updated and thus removed in a few releases. (Around end of 2022)

Parallel

• Re-structure the binary layout for V2 to be flat (no tarball, compression, etc.)
  • Change all beats to start without reading a configuration file from the disk (preferably they should start, context to control protocol and wait for initial configuration)
    • Beats run under agent should start without reading a configuration file from disk. beats#31901
• Change beats to understand configuration directly from policy (all rules are removed in the V2 binary specification)
  • Migrate filebeat and metricbeat to the V2 agent specification file format beats#31900
• Implement V2 control protocol in libbeat (having all beats using V2)
  • Migrate libbeat agent management to the agent V2 control protocol beats#32078
• Implement V2 control protocol in Endpoint Security

Sequential

• Implement validation and reading of the V2 binary specification
• Implement V2 control protocol server in Elastic Agent
• Parse Elastic Agent policy with V2 binary specification to spawn Units and be controlled through the V2 protocol
