&quot;&quot;&quot;changeset_published is a hook to send a mail when an
existing draft changeset is moved to the public phase.

Correct message threading requires the same messageidseed to be used for both
the original notification and the new mail.

Usage:
  [notify]
  messageidseed = myseed

  [hooks]
  txnclose-phase.changeset_published = \
    python:hgext.hooklib.changeset_published.hook
