Merging in Git is typically fairly easy. Since Git stores and has access to the full graph of revisions, it can automatically find where the branches diverged, and merge only those divergent parts. This works even in the case of repeated merges, so you can keep a very long-lived branch up to date by repeatedly merging into it or by rebasing it on top of new changes.

However, it is not always possible to automatically combine changes. There are problems that Git cannot solve, for example because there were different changes to the same area of a file on different branches: these problems are called merge conflicts. Similarly, there can be problems while reapplying changes, though you would still get merge conflicts in ...
