Just about everyone has already blogged about it, but APEX 4.0 EA is available now. <a target="_blank" href="http://tryapexnow.com/">http://tryapexnow.com/</a> What else is there to say that has not already been said? Not much probably, but I'll point out one new feature: APEX 4.0 is not available in Internet Explorer. I have it on good authority that this feature will only be in the beta and will not make it into the production release--we can hope, though. (Thanks to Neelesh Shah for pointing out this new feature.) 
Also, check out the new SQL Developer features: <a target="_blank" href="http://krisrice.blogspot.com/2009/12/application-express-and-anonymous.html">http://krisrice.blogspot.com/2009/12/application-express-and-anonymous.html</a>
