Just a quick note to say that OTM v5.5 CU04 has been released and is on the Oracle Metalink site earlier than I had expected! The patch number is 6705191 and it's a whopper (640MB for Linux). You can find the release notes here:

We haven't installed it yet, but plan to play with it in late December / early January and will report back.
BTW - thank you Shells for the tip
