As of yesterday, the 10.1.3.4 Application Server is available on OTN for download. Note, that this is not a full-blown install, it’s a maintenance release, a patch on top of 10.1.3.2. Search for 10.1.3.4 patch on the download page.
As announced on Shay’s blog, the “brand new” version of JDeveloper 10g is available for download. It comes with a couple of dozen bug fixes on the JSF view and ADF BC front. From the WebCenter side fixes range from content management (Universal Content Management – fka: Stellent), to WSRP interoperability (for consuming portlets produced by Web Logic Portal) and several upgrade related bugs.
As always, the Studio Edition comes with the WebCenter extension installed.
