### 0.4.0 - 2016-04-05

This is a major release with plenty of new features and bugfixes.
It also includes breaking changes which make it incompatible with v0.3.x
on the networking layer.

* Major Changes
  * Multistream
    * The addition of multistream is a breaking change on the networking layer,
      but gives IPFS implementations the ability to mix and match different
      stream multiplexers, e.g. yamux, spdystream, or muxado.
      This adds a ton of flexibility on one of the lower layers of the protocol,
      and will help us avoid further breaking protocol changes in the future.
  * Files API
    * The new `files` command and API allow a program to interact with IPFS
      using familiar filesystem operations, namely: creating directories,
      reading, writing, and deleting files, listing out different directories,
      and so on. This feature enables any other application that uses a
      filesystem-like backend for storage, to use IPFS as its storage driver
      without having change the application logic at all.
  * Gx
    * go-ipfs now uses [gx](https://github.com/whyrusleeping/gx) to manage its
      dependencies. This means that under the hood, go-ipfs's dependencies are
      backed by IPFS itself! It also means that go-ipfs is no longer installed
      using `go get`. Use `make install` instead.
* New Features
  * Web UI
    * Update to new version which is compatible with 0.4.0. (@dignifiedquire)
  * Networking
    * Implement uTP transport. (@whyrusleeping)
    * Allow multiple addresses per configured bootstrap node. (@whyrusleeping)
  * IPNS
    * Improve IPNS resolution performance. (@whyrusleeping)
    * Have dnslink prefer `TXT _dnslink.example.com`, allows usage of CNAME records. (@Kubuxu)
    * Prevent `ipfs name publish` when `/ipns` is mounted. (@noffle)
  * Repo
    * Improve performance of `ipfs add`. (@whyrusleeping)
    * Add `Datastore.NoSync` config option for flatfs. (@rht)
    * Implement mark-and-sweep GC. (@whyrusleeping)
    * Allow for GC during `ipfs add`. (@whyrusleeping)
    * Add `ipfs repo stat` command. (@tmg, @diasdavid)
  * General
    * Add support for HTTP OPTIONS requests. (@lidel)
    * Add `ipfs diag cmds` to view active API requests (@whyrusleeping)
    * Add an `IPFS_LOW_MEM` environment veriable which relaxes Bitswap's memory usage. (@whyrusleeping)
    * The Docker image now lives at `ipfs/go-ipfs` and has been completely reworked. (@lgierth)
* Security fixes
  * The gateway path prefix added in v0.3.10 was vulnerable to cross-site
    scripting attacks. This release introduces a configurable list of allowed
    path prefixes. It's called `Gateway.PathPrefixes` and takes a list of
    strings, e.g. `["/blog", "/foo/bar"]`. The v0.3.x line will not receive any
    further updates, so please update to v0.4.0 as soon as possible. (@lgierth)
