Skype for Business Server 2019 Cumulative Updates (CU) List

With the release of SfB Server 2019 i thought id create a Skype for Business Server Cumulative Update list, release dates and also download source.

Something i often search for with Lync and SfB Server and perhaps others may find helpful in the future.
