UPGRADING FROM AN EARLIER VERSION: Just unpack the new distribution archive wherever you need/want it; all you need from your old Wikka installation is wikka.config.php. You can also just copy the new files over the old ones, but be careful not to overwrite your old wikka.config.php or any customizations you may have applied to the source files. Once the files are in place, browse to your Wikka. The update script should show up automatically. Note: before you complete the update script, everybody who will browse to your Wikka will see it, too. So if you run a relatively high traffic site, you may want to lock down your Wikka installation temporarily by placing a file called "locked" into your Wikka directory; once Wikka sees it, it will ask for a username ("admin") and a password (whatever you put into that file). Don't forget to remove the "locked" file once you're done with upgrading! More details, hopefully, on <http://wikkawiki.org/UpgradeNotes>.
