I believe they have an "IPNS" protocol which is intended to handle mutations.

Any links, please?

You can read section 3.7 of their paper for an overview: http://static.benet.ai/t/ipfs.pdf

I imagine you could go through their codebase to try to see how far this has come along: https://github.com/ipfs/go-ipfs

According to this, it looks like the implementation is currently in progress: https://github.com/ipfs/go-ipfs/blob/master/dev.md

Hope something in there helps you.
