Hi All,
I wonder, with so many months passing since 5.4 has gone GA, and no
usuable, secure 5.4 client, will IBM be extending support of 5.3?
We are in the process of testing 5.3.5.5, as it fixes the security
issue in dsmcad, and does not have the preformance issues of 5.4.x. And
then in less than 7 weeks, we will be unsupported.
