[joblo2213]

The changelog must be updated to mention all changes.

So I had some boring training for my job that morning so I could update the changelog while the lecturer was talking about new fire saftey standards. :wink:

Now we only have to update it when we do make some changes. :tada:

I've updated all the PR's and 2.0 with changelog's entries so like docs they will be added as they are merged. Was there anything else or can this be closed?
