But when we go to merge master into feature, we’re going to run into trouble: (feature) $ git merge masterĬONFLICT (content): Merge conflict in myscript.pyĪutomatic merge failed fix conflicts and then commit the result. A common strategy is to routinely merge changes from master into your feature branch during development to keep the feature branch from getting too far out of date. So changes were made to myscript.py in both master and feature branches. The letters signify a commit, and each commit includes changes to our file: myscript.py.
