This repository is here for historical purposes only.
Current UnixFSv2 work is happen in the IPLD specs repository.
This repo is used to discuss and draft a specification for the next version of UnixFS (the DAG node format used to represent files and directories on the IPFS network). You can find and participate in discussion about desired features in the issues and an initial specification draft in PR #2.
When the specification draft is complete, it will be moved to the ipfs/specs repo at https://github.com/ipfs/specs/tree/master/unixfs and this repo will likely be re-dedicated to building the Go implementation of UnixFS.
