The front of the server manuals carries a summary of what's new in
each release.  Additionally, IBM maintains a tradition of creating a
redbook for each new release, with an exposition on new features: look
at http://www.redbooks.ibm.com/abstracts/sg247718.html.  And you can
search for specific details in IBM Technotes about TSM 6.1, as well as
review past customer postings on issues in the ADSM-L archives.

Note that the search function remains defective in the ill-conceived
generalized Support pages which arbitrarily replaced the once-great
TSM Support Page which IBM took away from customers.  (I had to press
the Web development department to acknowledge that the search function
was badly engineered, where Defect 1247 has been open since February
9th on resolving the problems therein.)
