I've been using sourcetree with gitflow, my first steps with these tools.
In error I made and commited changes in the master branch which is now 'ahead' of the develop branch.
By ahead I simply mean that the files listed under master have changes in them that have never been in Develop - hence I am worried that if I now develop a feature branch from develop I am going to be doing so on a version that is less developed than the master and risk losing those changes when develop later gets merged to master on completing a new release.
The changes I made were good and I want to preserve them, and get back to creating new features as branches from the development branch, later merging them into the master as new releases.
What is the best way to get things back on track?
