Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
strip: introduce -B option to remove a bookmark Add a -B option to remove a bookmark. All revisions are unreachable from a different head or a different bookmark will be removed too. This helps with topic branch workflow. You can create a topic branch and remove it if not needed anymore with hg strip -B topic/xyz.
