Oracle have released an updated version of SQL Developer and it is available to download from here.
Jeff Smyth has a blog post on some of the bug fixes in SQL Developer.
and Kris Rice also has a blog post on the new updated release.
So what about Oracle Data Miner. There seems to be a couple of minor new features on being able to select statistical outputs for the transform node. Also the model and test results viewers now automatically refresh if they are open. ODM can not be installed on Oracle Personal Edition (I haven't tried this out yet).
Plus the Graph node can not have line charts based on mulitiple y axis attributes. I'll have a blog post on this soon.
