I am trying to understand what these Atlassian products are and how they relate to each other. I know there used to be a product call "Stash" that was renamed "Bitbucket Server". Howevever, there used to be a product called "Bitbucket" which was separate from "Stash".
When "Stash" was renamed to "Bitbucket Server", what happened to "Bitbucket"? Were the two products merged?
How does "SourceTree" fit in? Is it a completely separate product? Why is there a link for it on the Bitbucket main page (https://www.atlassian.com/software/bitbucket)?
