Just before the holiday weekend here in the states, it looks like APEX 3.1.2 is available as Metalink Patch #7313609. More details can be found here.
A recent thread on the OTN HTML DB Forum asked about how to determine the width & height of an image stored as a BLOB in an Oracle table. I mentioned in that thread that I have some code to manipulate an image stored in a BLOB column. This is particularly useful if you’re going to let users upload images, and you want to re-size them to display as a thumbnail. Thanks to Oracle interMedia , it is trivial to manipulate the width, height, and other attributes of images stored in an Oracle table. I’ve created a sample application here which demonstrates Oracle interMedia and HTML DB in action. Feel free to have a look. You can download this application from HTML DB Studio as well. Basically, this application allows you to upload images and perform an operation on the image as it is inserted into the PHOTO_CATALOG table. There are two places where some PL/SQL code is required: an After Submit process on page 2, and a procedure to display the images. Here is the PL/SQL for the After...

The book has taken longer than we anticipated it for a number of reasons. Suffice it to say, it should be out sooner rather than later, and we all look forward to its release.
As for its relevance, I feel that it will be extremely relevant. The book takes a larger view of APEX than just APEX itself, and most of the technologies that surround APEX are largely constant and unchanged. APEX itself has not undergone any major changes from 3.0 to 3.1. Sure, there's a few new features, but by and large, the Application Builder is almost identical to what it was in 3.0.
Thanks,
