More information will soon be posted at http://www.cs.toronto.edu/~james/greasemonkey/ Version 0.1 -- Initial Version Version 0.2 -- Upgraded to be more robust to changes in the gmail code Version 0.3 -- Fixed crash bug when multiple reply windows were open at the same time Version 0.4 -- Fixed performance problems Version 0.5 -- Added fix to correct bug in Gmail where attachments are lost Version 0.6 -- Added mail.google.com/mail* to list of URLs Version 0.7 -- Added fix to prevent overly frequent saves */ (function() { var JS = top.js;
