| Note: At present, there is no interoperability between SHA-256 | |
| repositories and SHA-1 repositories. | |
| Historically, we warned that SHA-256 repositories may later need | |
| backward incompatible changes when we introduce such interoperability | |
| features. Today, we only expect compatible changes. Furthermore, if such | |
| changes prove to be necessary, it can be expected that SHA-256 repositories | |
| created with today's Git will be usable by future versions of Git | |
| without data loss. |
