I'm using Wordpress version 2.6.2 and now it shows in the page that
Deprecated: Assigning the return value of new by reference is deprecated in /home/np14388/domains/<sitename>/public_html/wp-settings.php on line 472
etc. Is it safe to update from this version to the newest one, or should I update in certain phases (2.6.2 -> 2.6.3 etc.)? Please help.
