Action Items from previous meeting:

Blog / Documentation
- Completions
  - What is code generated from ACSERRDEF and what needs to be implemented by the developers?
  - Hands-on each programming language
    - Including the check of the completion's state
- Alarm System documentation seems a bit stale
  - Is the latest documentation (~2014) still valid?
  - Could it be updated and moved to Confluence?
- More simple examples for all programming languages
  - It seems Java has received more attention, but it would be nice to have examples in all programming languages
