  *  Added fork warning to be issued if sync produced a fork
  *  Update the [/help?cmd=/info|info] page to report when a file becomes a
     symlink.  Additionally show the UUID for files whose types have changed
     without changing contents or symlink target.
  *  Have [/help?cmd=changes|fossil changes] and
     [/help?cmd=status|fossil status] report when executable or symlink status
     changes on otherwise unmodified files.
  *  Permit filtering weekday and file [/help?cmd=/reports|reports] by user.
     Also ensure the user parameter is preserved when changing types.

<h2>Changes for Version 1.32 (2015-03-14)</h2>
  *  When creating a new repository using [/help?cmd=init|fossil init], ensure
     that the new repository is fully compatible with historical versions of
     Fossil by having a valid manifest as RID 1.
  *  Anti-aliased rendering of arrowheads on timeline graphs.
  *  Added vi/less-style key bindings to the --tk diff GUI.
