* Avoid `Content-Length: 0` in GET requests (#103)
* Fix bug in Trusted
* Build tar-index incrementally (#22)
* Generalize 'Repository' over the representation of downloaded remote files.
* Update index incrementally by downloading delta of `.tar.gz` and writing only
  tail of local `.tar` file (#101). Content compression no longer used.

* Code refactoring/simplification.
* Support for ed25519 >= 0.0.4
* `downloadPackage` no longer takes a callback.
* API for accessing the Hackage index contents changed; it should now be

* Removed obsolete option for downloading the compressed index (we now _always_
  download the compressed index)

* Replaced uses of Int with Int54, to make sure canonical JSON really is
  canonical (#141).
