Problem Description:

As of posting the script is broken, but assuming it is resolved by https://github.com/Unimatrix0/update_ombi/pull/20 this will only allow updating to beta versions of Ombi and only builds that come from the develop branch. It would be nice if we could have the script handle updates only to stable releases, or for that matter to other branches. In the case of https://github.com/Unimatrix0/update_ombi/pull/20 as you can see by the commit history the DotNetCore branch was renamed to develop after the initial PR was made, which furthers my opinion that the need for handling multiple branches should be considered.
