2015-02-20 io.js v1.3.0 Release

Notable changes:

* url: `url.resolve('/path/to/file', '.')` now returns `/path/to/`
  with the trailing slash, `url.resolve('/', '.')` returns `/`.

* tls: tls (and in turn https) now rely on a stronger default
  cipher suite which excludes the RC4 cipher. If you still want to
  use RC4, you have to specify your own ciphers suite.
