## Upgrading from 1.x to 2.0.0

Make sure you use Ruby 2.0 or higher.

Update the `Plaid.config` block:

```ruby
Plaid.config do |p|
  p.client_id = '<<< Plaid provided client ID >>>'  # WAS: customer_id
  p.secret = '<<< Plaid provided secret key >>>'    # No change
  p.env = :tartan  # or :api for production         # WAS: environment_location
end
```

Use `Plaid::User.create` instead of `Plaid.add_user` (**NOTE**: parameter order has changed!)

Use `Plaid::User.load` instead of `Plaid.set_user` (**NOTE**: parameter order has changed!)

Use `Plaid::User.exchange_token` instead of `Plaid.exchange_token` (**NOTE**: parameter list has changed!)

Use `Plaid::User.create` or (`.load`) and `Plaid::User#transactions` instead of `Plaid.transactions`.

Use `Plaid::Institution.all` and `Plaid::Institution.get` instead of `Plaid.institution`.

Use `Plaid::Category.all` and `Plaid::Category.get` instead of `Plaid.category`.

`Plaid::Account#institution_type` was renamed to `Plaid::Account#institution`.

`Plaid::Transaction#account` was renamed to `Plaid::Transaction#account_id`.

`Plaid::Transaction#date` is a Date, not a String object now.

`Plaid::Transaction#cat` was removed. Use `Plaid::Transaction#category_hierarchy` and `Plaid::Transaction#category_id` directly.

`Plaid::Transaction#category` was renamed to `Plaid::Transaction#category_hierarchy`.

`Plaid::Transaction#pending_transaction` was renamed to `Plaid::Transaction#pending_transaction_id`.

Use `Plaid::User#mfa_step` instead of `Plaid::User#select_mfa_method` and `Plaid::User#mfa_authentication`.

`Plaid::User#permit?` was removed. You don't need this.

`Plaid::User.delete_user` was renamed to `Plaid::User.delete`.

**NOTE** that Symbols are now consistently used instead of Strings as product names, keys in hashes, etc. Look at the docs, they have all the examples.
