  • Status changed from Code review to In Progress

If the implementation is "partial":

  • Issue status should remain as InProgres. CodeReview should be used only if the final commit has been uploaded.
  • Indicate exactly which features have been implemented (refer to the list of requirements in spec). This allows a reviewer to look at these features only, and allows a future developer to make another commit for remaining features.
