The latest MapViewer release, version 10.1.3.3 for WebLogic, just saw an update yesterday. Please go to http://www.oracle.com/technology/software/products/mapviewer/index.html for immediate download.
This kit is released under the same bundle name (mapviewer10133wls.zip) but the MapViewer component (mapviewer.ear) in it has been updated to include a few last minute bug fixes. If you have experienced issues with Oracle Maps when doing very fast zooming operations, such as FOI features throwing errors or base map tiles disappearing, then you want to download and deploy this latest kit.
Note again that while this kit is certified on WebLogic Servers, you can also deploy it to all 10.1.3.* versions of OC4J standalone and Oracle App Server. This kit also supersedes all previously released MapViewer 11g previews in functionality and stability.
