+                  A: Yes, you can revert to a previous version of task,
+                     simply by downloading an
+                     <a href="versions.html">older version</a> and
+                     installing it.  If you find a bug in task, then this
+                     may be the only way to work around the bug, until a
+                     new release is made.

+                  Note that it is possible that the task file format will
+                  change.  For example, the format changed between versions
+                  1.5.0 and 1.6.0.  Task will automatically upgrade the file
+                  but if you need to revert to a previous version of task,
+                  there is the file format to consider.  This is yet another
+                  good reason to back up your task data files!
