We have published an updated Statement of Direction for Application Express and plan on calling out next major release APEX 5.0.
This outlines the major features we *plan* on delivering, however, as always there is also a large number of other features we have listed in Team Development for this release. These are covered under the "Numerous functional improvements" bucket. Many of the features we are planning to deliver come from the APEX Feature Request Application.
As always our disclaimer (as listed at the bottom of the Statement of Direction page) in relation to such forward looking statements applies.
Looks like our team is going to busy ... again!!!
