## [2.0.0] - 2022-12-15
### Updated

- the `kyu_channel` now interacts with channels directly
- the `kyu_consumer` and `kyu_worker` modules are now more robust
    - they require less channels
    - the `kyu_wrangler` layer was completely removed, so workers now receive messages directly
    - the `kyu_worker` module supports more optional callbacks (`init/1`, `handle_call/3`, `handle_cast/2`, `terminate/2`)
    - consumer behaviour is more predictable due to a single `prefetch_count` option (`worker_count` was removed)
    - `duplex` consumers now use a single channel to receive and publish messages
    - workers can now retreive their channels using `kyu_worker:channel/0`
- publishers can now be pooled using `kyu_publisher:child_spec/2` or `kyu_publisher:start_link/2`
- publishers don't require you to set `mandatory` on a message when using the `supervised` execution mode
