WordPress has just released WordPress v2.5, which I have completed upgrading my blog to. I have also upgraded my plugins to their latest versions using the new plugin update feature and it worked great!
As always, I did have to modify the /wp-includes/vars.php file in the server detection section to force the apache detection to true so that it could modify the permalink structure:
// Server detection /** * Whether the server software is Apache or something else * @global bool $is_apache */ //$is_apache = ((strpos($_SERVER['SERVER_SOFTWARE'], 'Apache') !== false) || (strpos($_SERVER['SERVER_SOFTWARE'], 'LiteSpeed') !== false)) ? true : false; $is_apache = true; /** * Whether the server software is IIS or something else * @global bool $is_IIS */ $is_IIS = (strpos($_SERVER['SERVER_SOFTWARE'], 'Microsoft-IIS') !== false) ? true : false;
The reason is that Surpass Hosting’s value for $_SERVER['SERVER_SOFTWARE'] is WebServerX. I also updated my theme to include all the updated code in the default WordPress theme which mine is based off of. All in all a fairly painless process. 
Thought I would comment on my own post to mention that recently Surpass upgraded Apache and PHP on the server and the SERVER_SOFTWARE now reports as Apache and thus this change would no longer be necessary.
