The Packaging and Availability page of the dsmtop Wiki indicates that updated versions of dsmtop will be published here on developerWorks in both "Standalone" and "sqllib" packages. However, no new versions have been posted since May, 2016.
I know that there are newer versions (i.e. what's included in DB2 184.108.40.206), and even saw that there was a very recent build (1.4.3, buildDate = 2017-02-13) that was published in a Special Build of DB2 220.127.116.11.
Are there plans to continue offering up-to-date downloads of the standalone and sqllib versions of dsmtop here? Downloading a full fix pack (or special build) just to get a later version of dsmtop is significantly less convenient.
