I need list of cognos version (cognos 7 to cognos 8.4.1 ) and released date.
Fix pack released for each version. Kindly version for ASAP.
Have you looked on the IBM website?
Just refer to http://www-933.ibm.com/support/fixcentral/ and select product you are looking for Fixpacks.
Not sure why you are not able to find this by google ? Anything specific you are looking for ?
Release dates might be tough but you could probably come close by looking at file timestamps of the contents
If you are trying to figure out the supported platform / end of life for releases, there's a page somewhere in the nightmarish IBM site that lists the currently supported and end of life for releases. They change it around from time to time. For example, support for Planning 8.1 changed from expiration early this year to end of this year (2010) - at least the last time I looked.
