 Version 0.8.1 ()

+    * Fix possible XSS when using the templatedropdown or shoutbox
+      plugins (garvinhicking)
+
+    * Fix pagination of "Entries by Author" (garvinhicking)
+    
     * Fix RSS 1.0 missing top-level namespace (garvinhicking)
 
+    * Deactivated gzip compression by default, as in certain server
+      setups it creates problem with double-encoding or missing
+      ob_gzhandlers. (garvinhicking)
+
     * Allow the serendipity_event_trackback additional trackbacks plugin
       to send trackbacks even if your entry did not contain at least one
       link. Also fix not sending trackbacks containing "#" fragments

     * Do not display Sidebar titles if they are not set for the bundled 
       default, kubrick and wp templates (sidebar.tpl) (garvinhicking)
 
+    * Fix error "Warning: ob_start(): output handler 'ob_gzhandler' 
+      cannot be used after 'URL-Rewriter'" which can occur on installations
+      where session.use_trans_sid is activated and Serendipity's gzip

     * Adjusted checking for "convert" binary in installation for
       Windows servers. Thanks to BobRock! (garvinhicking)
