# Changelog

## v0.5.0

### Breaking changes

- Bump the Elixir version to ~> 1.6.
- Bump the Redix version to ~> 0.8.
- Require Erlang/OTP 20+.
- Change message format to always include a subscription reference (returned by `Redix.PubSub.subscribe/3` or `Redix.PubSub.psubscribe/3`) as the third element. The format is now `{:redix_pubsub, pubsub_pid, subscription_ref, message_type, message_properties}`. Change your code accordingly or it won't
match on pub/sub messages anymore. See the documentation for `Redix.PubSub` for detailed information on the message format.
- Change the return value of `Redix.PubSub.subscribe/3` and `Redix.PubSub.psubscribe/3` to be `{:ok, subscription_ref}`.
- Make all subscribe/unsubscribe functions blocking until the pub/sub connection can process them.

### Bug fixes and improvements

- Add support for SSL through the `ssl: true | false` option in `Redix.PubSub.start_link/0,1,2`.
