| # Upgrading from v1 to v2 |
| |
| The change from v1 to v2 was fairly minor: the return type of the `Open` method |
| on the `OS` interface was changed from `*os.File` to `File`, a new interface |
| exported by doublestar. The new `File` interface only defines the functionality |
| doublestar actually needs (`io.Closer` and `Readdir`), making it easier to use |
| doublestar with [go-billy](https://github.com/src-d/go-billy), |
| [afero](https://github.com/spf13/afero), or something similar. If you were |
| using this functionality, updating should be as easy as updating `Open's` |
| return type, since `os.File` already implements `doublestar.File`. |
| |
| If you weren't using this functionality, updating should be as easy as changing |
| your dependencies to point to v2. |
