1.x to 2.x Migration Guide

The 3.x release is an overhaul of the SDK's API to simplify integration and align it with the iOS SDK.

• The content provider is no longer necessary. Instead, call Plaid.initialize(application) to initialize the SDK
• PlaidOptions has been removed, instead pass environment and logLevel in your LinkConfiguration
• The PlaidLinkResultHandler no longer requires a request code
• The onCancelled callback has been removed, all exit events will be returned in onExit
• Adds support for Account Subtype filtering
• Kotlin functions have been added for a more semantic API
• Several object and field names have been adjusted

For an example demonstrating how to migrate from the 1.x to 2.x SDK, see a sample migration on GitHub.
