title: Is it possible to download previous nightly builds?
body: <p>I have downloaded the latest Rust nightly and added this dependency to Cargo.toml:</p>
  
  <pre><code>[dependencies.http]
  
  git = "https://github.com/chris-morgan/rust-http.git"
  </code></pre>
  
  <p>I'm getting lots of errors for <code>cargo build</code>:</p>
  
  <pre><code>...
  error: aborting due to 7 previous errors
  ...
  error: aborting due to previous error
  Could not compile `regex`.
  </code></pre>
  
  <p>I guess this is because some dependencies have not been updated to the latest rust version. Is it possible to download the nightly from yesterday or the day before?</p>
  
  <p>Installed versions:</p>
  
  <pre><code>$ rustc --version
  rustc 0.13.0-nightly (c89417130 2015-01-02 21:56:13 +0000)
  $ cargo --version
  cargo 0.0.1-pre-nightly (1a1868b 2014-12-31 21:39:41 +0000)
