Upgrading iex-ruby-client
=========================

### Upgrading to >= 1.6.0

[#110](https://github.com/dblock/iex-ruby-client/pull/110) drops the dependency on `money_helper` in favor of using the `money` library directly.

Previously the `money_helper` library set `Money.locale_backend = :currency` globally. The default is `I18n` which looks up the thousands separator and decimal marker. Depending on your project you may need to set this value if you use `Money#format` without the `thousands_separator` or `decimal_mark` options. You are less likely to require this in a Rails project.

This represents a change in the `money` library's method of handling defaults and is similar to the deprecation warning the library provides until you set `Money.rounding_mode=`.

### Upgrading to >= 1.0.0

On June 1, 2019, IEX API has been sunset for all non-IEX data. IEX Cloud, a non-Exchange platform, continues to provide access to third-party data sources and requires a token. When upgrading to 1.0.0, create an account and get a `publishable token` from [IEX Cloud Console](https://iexcloud.io).

Set the environment variable `IEX_API_PUBLISHABLE_TOKEN` to the token value, or configure the client via `IEX::Api::Client.new` or `IEX::Api.configure`.

Before:

```ruby
IEX::Resources::Price.get('MSFT')
```

After:

```ruby
client = IEX::Api::Client.new(publishable_token: 'token')

client.price('MSFT')
```

### Upgrading to >= 0.4.0

#### All errors that return HTTP codes 400-600 result in a IEX::Errors::ClientError exception

On previous versions, calling `IEX::Resources::Chart.get` with an invalid option results on a
`Faraday::ClientError`. On versions >= 0.4.0, it will return an `IEX::Errors::ClientError`.

Before:

```ruby
IEX::Resources::Chart.get('MSFT', '1d', chart_interval: 10, invalid_option: 'foo')
> Faraday::ClientError: the server responded with status 400
```

After:

```ruby
IEX::Resources::Chart.get('MSFT', '1d', chart_interval: 10, invalid_option: 'foo')
> IEX::Errors::ClientError: "invalidOption" is not allowed
```
