Update: The part number has changed and is now: CN54LML.
Very quietly IBM Docs 1.0.7 was released just now, alongside with Connections 5.0 CR2. You can find it using part number CN30NML.
Here is the updated link to the Knowledge Center:
New things in IBM Docs 1.07 are the centralised graphical installer, the completely rewritten editor for documents, integration with Sametime, Filenet as well as CCM Libraries.
If you have version 1.0.6 installed: This is a MANDATORY install. 😉
