It wasn’t exactly a surprise as the APEX 19.1 Early Adopter site was shutdown and there was a maintenance window on apex.oracle.com, which is running APEX 19.1.
I downloaded the 19.1 software and plugged though my Vagrant and Docker stuff bringing it up to date. If you are into that stuff you can find it on my GitHub.
I guess this means I can start the process of upgrading everything at work on Monday. 🙂
