v0.8.0

This release adds support for run numbers, and includes an overhaul of the configuration mechanism.
Users should update their configuration files and/or o2control-core command invocation. For more information, run o2control-core --help and see hacking/settings.yaml and hacking/settings.yaml.example.

  • [core] Propagate run number to tasks in START_ACTIVITY transition
  • [core] Gather common arguments (such as run number) before transition
  • [core] Generate run number and push it down
  • [core] Add run number to API and regenerate proto
  • [core] Add environment.GetCurrentRunNumber
  • [core] Run numbers start from 1, 0 is a null-value as in Protobuf
