v0.049

  [Changes]

  - Support Gerrit's draft-published hook which is invoked when a draft
    change is published.

  - New githooks.nocarp configuration variable to suppress the script line
    number on error messages.

  - New githooks.gerrit.comment-ok configuration variable to add a comment
    to a positive review in Gerrit.

  - All error messages are now printed in a specific format.

  - Released at #cpanday.

  [Fixes]

  - Git configuration variables can't have underscores in their names. So,
    this version changes the names of three of them under the
    githooks.gerrit section: review_label, vote_ok, and vote_nok. They are
    now: review-label, vote-ok, and vote-nok.

  - The patchset-created hook wasn't setting up the configuration variables
    correctly.

  - Draft changes in Gerrit don't trigger the patchset-created hook anymore,
    because only the draft owner can review it.
