Whilst I've been able to find historic information relating to the Live Communications Server (and subsequent versions as it was rebranded), what I haven't been able to find is a definitive list of the release dates for both the client/server applications of the following:
Live Communications Server 2003
Live Communications Server 2005
Office Communicator 2007
Lync 2010
Lync 2013
Skype for Business 2015
Skype for Business 2016
Skype for Business 2019
Does such a list exist, or is there a single place that lists the release dates for these applications?
