In case you haven’t noticed already, David Peake’s blog just announced that APEX 4.0 moves one step closer to become available for download. It is now the release that powers apex.oracle.com.

This is good news as it shows that the release is getting close to be completed. Upgrading apex.oracle.com is usually one of the last public steps before a release becomes available to download.
