I'm using Sourcetree 2.6.10 for Windows. When I launch the application I get a warning telling me that Git-flow is not supported and that I should upgrade to Git 2.17.1.2.
Under Tools/Options/Git the application shows that I'm using Embedded Git version 2.17.1/LibGit2Sharp 0.24.0 + git-lfs v2.4.2 so I don't understand why I'm getting the warning.
Is there something more that I need to do?
