Checklist

Please verify the following checklist in order:

• If releasing module changes, the Pull Request title is prepended with "[<Azure Stack Hub Release Version>]". E.g., a title may be "[2301] Compute RP changes". Otherwise, this is not necessary.
• Updated origin dev branch locally. (git fetch origin dev)
• The Pull Request has a single commit. The following is a standard way to achieve a single commit:
  • git checkout feature
  • git rebase origin/dev -i
  • In the VIM editor press ESC and i to enter edit mode.
  • Select commits to fixup or squash commits (instructions are in the editor).
  • Press ESC, type :wq, and press Enter to save and quit.
• Resolved any rebase conflicts (basically merge conflicts).
• Commits are rebased on top of latest remote dev branch.
• The changes are tested. Make sure to test after the rebase step.
• Updated remote feature branch. (Force push if you've rebased onto new changes from dev: git push origin feature -f)
