Some companies are beginning to move to Microsoft Visual Studio (TFS) version 2017. The latest version mentioned in the Qlikview 12.xx Source Control with Team Foundation Server and Visual Studio documentation for use with QlikView Source Control is Visual Studio 2012, document attached.
Jira issue QV-12741 "Evaluate Latest version of Visual Studio(TFS) for QV 12 source control" entered 12-01-2017.
R&D replied to the Jira issue stating there are no plans at this time to test TFS 2017.
I reached out to one of the CSM's at Qlik to find out if there are any other options for QlikView customers wanting to implement Source Control. The response was many clients are using a solution called Platform Manager from a company In4BI out of Netherlands. In4BI has a Technology Partnership with Qlik. https://in4bi.com/
They have a solution for Qlik Sense as well.
