+  <li>Fixed a bug where the operator attribute windows will show the default attributes when displaying the attributes for an operator applied to a plot after restoring a session. The plots displayed in the visualization windows will be correct, just the attributes displayed in the attribute window will be incorrect. This happens with session files saved with releases 3.4 and 3.4.1. To fix the issue you will need to save a new session file using a newer version of VisIt. If you restored a session with a bad session file, you will need to change the attributes of any affected operators before saving the new session file.</li>
