## Breaking changes

- Renamed artifact from `nylas-java-sdk` to `nylas`.
- Nylas SDK v2 supports Nylas v3 exclusively, dropping support for any endpoints that are not available in v3. See [v3 Features and Changes](/docs/v2/upgrade-to-v3/features-and-changes/) for more information.
- Moved all REST calls from models into resources.

## Added

- Full Kotlin support.
- Created models for all API resources and endpoints, for all HTTP methods to reduce confusion on which fields are available for each endpoint.
- Created error classes for the different API errors as well as SDK-specific errors.

## Updated

- Now using Moshi annotations for JSON serialization/deserialization as opposed to manually writing JSON maps.
- Removed all REST calls from models and moved them directly into resources.

## Removed

- Non-builder ways for initializing `NylasClient`.
- Local Webhook development support is removed due to incompatibility with the new API version.
