APEX 20.1 is now live on apex.oracle.com. I took some time to dig around some features, but one that stuck out right away was the new template options for the login screen.
On your login page, go to Template Options:
Change Page Layout -> Split
Note: The different page backgrounds you can choose are dynamic to the theme roller.
Voila! You have a new slick login page that even has a nice slide in animation. Also check out the new friendly urls 😉
