Recently Oracle released a new early adopter version of Apex 5.0. All workspaces from the early adopter 1 have been purged, so those who are interested need to request a new workspace.
In the ea 1 release we all ready saw some major new changes. The latest release contains some minor upgrades, most notably:
- New Packaged Application capabilities introduced in Application Express 5.0
- New theme features introduced in Application Express 5.0. The most important aspect being the 'Universal Theme'
- New Websheet capabilities introduced in Application Express 5.0
With ea2 released it looks like we're heading to an official release of Apex 5.0. That release is planned later this year, possibly late summer/early fall.
Until that time, have fun exploring the early adopter version.
