Rules for processing Change Requests

 

  • Each of the relevant change requests should be discussed separately - related change requests may be discussed together.
  • We will add new CRs to the discussion as appropriate. In general we will start by raising issues, discuss them, agree on revision of the CR as appropriate and eventually vote by email.
  • To support the discussions we will use bi-weekly telecons.
  • CRs for which no concrete proposal is available after the discussion phase will be put on hold until a concrete proposal is available. If no concrete proposal can be prepared, it will likely be deferred to a later version.
  • If a CR passes an email vote with less than a 2/3 majority, it will be discussed in the next meeting.
