Git v1.8 backwards compatibility with Git v1.7

Question

If I upgrade from git 1.7 to git 1.8 on my server, do I have to update my repository too? Will a git 1.7 client work with a git 1.8 server and vice versa? Is there anything to be concerned about?

Answer 1

do I have to update my repository too?

No, the internal format of a repo remains compatible.

Will a git 1.7 client work with a git 1.8 server and vice versa?

Yes, there is little change in the transport protocol (mainly in http protocol).

The protocol capabilities don't mention any backward compatibility issue.
