### Breaking Change

`Mua` is bumped to `0.2.0`, and brings some breaking changes. The [change](https://github.com/ruslandoga/mua/pull/44) in v0.2.0 is splitting `transport_opts` into `tcp` and `ssl` specific ones since `:gen_tcp.connect` complains when it receives opts for `:ssl.connect`.

## 1.4.0

### Add `Swoosh.ApiClient.Finch`

You can configure what API Client to use by setting the config. Swoosh comes with
`Swoosh.ApiClient.Hackney` and `Swoosh.ApiClient.Finch`

```elixir
config :swoosh, :api_client, MyAPIClient
```

It defaults to use `:hackney` with `Swoosh.ApiClient.Hackney`. To use `Finch`,
add the below config

```elixir
config :swoosh, :api_client, Swoosh.ApiClient.Finch
```

To use `Swoosh.ApiClient.Finch` you also need to start `Finch`, either in your
supervision tree

```elixir
children = [
  {Finch, name: Swoosh.Finch}
]
```

or somehow manually, and very rarely dynamically

```elixir
Finch.start_link(name: Swoosh.Finch)
```

If a name different from `Swoosh.Finch` is used, or you want to use an existing
Finch instance, you can provide the name via the config.

```elixir
config :swoosh,
  api_client: Swoosh.ApiClient.Finch,
  finch_name: My.Custom.Name
```
