In-place edit of issue states and fields
Issue states and fields can now be edited in place in issue list and board, which makes issue editing much more convenient

Issue link
Issue link to set up relationships between issues, such as parent-child, blocking/blocked by etc. Issue state transition can also leverage the link information to make the workflow smoother, for instance, to auto-close an issue if all its sub tasks are finished, or prevent an issue from being closed if any issue blocking it is still open.
