Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
transaction-summary: show the range of new revisions upon pull/unbundle (BC) Upon pull or unbundle, we display a message with the range of new revisions fetched. This revision range could readily be used after a pull to look out what's new with 'hg log'. The algorithm takes care of filtering "obsolete" revisions that might be present in transaction's "changes" but should not be displayed to the end user.
