# Changelog

## v0.3.0

* Change the behaviour for an empty list of command passed to `Redix.pipeline/2`
  (`Redix.pipeline(conn, [])`), which now raises a `Redix.ConnectionError`
  complaining about the empty command. Before this release, the behaviour was
  just a connection timeout.
* Change the behaviour of empty commands passed to `Redix.command/2` or
  `Redix.pipeline/2` (e.g., `Redix.command(conn, [])` or `Redix.pipeline(conn,
  [["PING"], []])`); empty commands now return `{:error, :empty_command}`. The
  previous behaviour was just a connection timeout.
* Remove `Redix.start_link/1` in favour of just `Redix.start_link/2`: now Redis
  options are separated from the connection options. Redis options can be passed
  as a Redis URI as well.
* Changed the error messages for most of the `Redix.ConnectionError` exceptions
  from simple atoms to more meaningful messages.

## v0.2.1

* Fix a bug with single-element lists, that were parsed as single elements (and
  not lists with a single element in them) by
  `Redix.Protocol.parse_multi/2`. See
  [whatyouhide/redix#11](https://github.com/whatyouhide/redix/issues/11).

## v0.2.0

* Rename `Redix.NetworkError` to `Redix.ConnectionError` (as it's more generic
  and more flexible).
* Add support for PubSub. The following functions have been added to the `Redix` module:
  * `Redix.subscribe/4`
  * `Redix.subscribe!/4`
  * `Redix.psubscribe/4`
  * `Redix.psubscribe!/4`
  * `Redix.unsubscribe/4`
  * `Redix.unsubscribe!/4`
  * `Redix.punsubscribe/4`
  * `Redix.punsubscribe!/4`
  * `Redix.pubsub?/2`
