From time to time the filesize of the ICQ setup changes, because they fix some small problems or change the content. But I don't know exactly because there are no change logs published.

Hello!
Yesterday I got a message in Windows 7 Action Center saying that I need to solve a problem with ICQ by downloading new version. I did download it from ICQ.com and it had different size from what I had earlier.
But after I installed it first of all what I noticed was that it made some kind of update which was shown in task bar.
When I launched it I checked Build number and it was the same - 1042.

Do you know what was changed in it?
And do you know where can I see Changelog for any version/build of ICQ if there is any?
Thanks
