You will not be supported through Oracle Support or the Forum, only the feedback site. You will not get the evaluation software from the production download site, instead follow the links through the short survey and on to the evaluation release download. (For subsequent downloads you'll be redirected past the survey) When you reach the download page, there are links to a few very useful documents:
- New Features - This is a list of new features, quite comprehensive, possibly missing a few little features here and there
- Known Issues - This is a list of bugs already logged, some already fixed in a later build and which you'll pick up in next week evaluation drop.
- Getting Started - This is really important. If you are using 1.0, there are some files you need to back up if you want to preserve them and go back to SQL Developer 1.0.
No, I can't tell you the production date yet.
