Research In Motion has issued updates for all of their instant messengers to version 2.1.42 only after updating to v2.1.41 just a couple of weeks ago.
Apparently there are no changes to the change log and Research In Motion hasn’t even bothered to put out any real announcement, so I guess you just update to check out if anything has changed at all.
Always nice to get updates, but it’s also nice to know just what the update actually achieves, so if anyone does do the update and finds anything different when using IM clients feel free to let us know.
