**   --setmtime        Set timestamps of all files to match their SCM-side
**                     times (the timestamp of the last check-in which modified
**                     them).
**   --verbose         If passed a URI then this flag is passed on to the clone
**                     operation, otherwise it has no effect
**   --workdir DIR     Use DIR as the working directory instead of ".". The DIR
**                     directory is created if it does not exist.
**   --reopen REPOFILE Changes the repository file used by the current checkout
**                     to REPOFILE. Use this after moving a checkout's
**                     repository. This may lose stash and bisect history.

       <li> "No-graph" timelines (using the "ng" query parameter) now show
            branch colors and bare check-in circles on the left.  The check-in
            circles appear, but no lines connecting them.
            ([/timeline?ng|example]).

  <li> The [/help/timeline|timeline command] is enhanced with the new
       "<tt>-u|--for-user</tt>" option.
  <li> The [/help/open|the open command]'s new "<tt>--reopen REPOFILE</tt>" flag
       can be used to fix a checkout after moving its repository file.

<h2 id='v2_27'>Changes for version 2.27 (2025-09-30)</h2><ol>
  <li> Close a potential Denial-of-Service attack against any public-facing Fossil
       server involving exponential behavior in Fossil's regexp implementation.
  <li> Fix a SQL injection on the [/help/www/file|/file page].  Thanks to
       additional defenses built into Fossil, as well as good luck, this injection
