**   --nochange | -n         Dryrun:  do not actually make any changes; just
**                           show what would have happened.

<title>Change Log</title>

<h2>Changes For Version 1.26 (as yet unreleased)</h2>
  *  Win32: Fossil now understands Cygwin paths containing one or more of
     the characters <nowiki>"*:<>?|</nowiki>. Those are normally forbidden in
     win32. This means that the win32 fossil.exe is better usable in a Cygwin
     environment. See
     [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars].
  *  Cygwin: Fossil now understands win32 absolute paths starting with a drive
     letter everywhere. The default value of the "case-sensitive" setting is
     now FALSE, except when case-sensitivity is enabled in the Windows kernel.
     See
     [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-casesensitive]
  *  Enhancements to /timeline.rss, adding more flags for filtering
     results, including the ability to subscribe to changes made
     to individual tickets. For example: [/timeline.rss?y=t&tkt=12fceeec82].
  *  JSON API: added the 'status' command to report local checkout status.

<h2>Changes For Version 1.25 (2013-02-16)</h2>
  *  Enhancements to ticket processing. There are now two tables: TICKET and
