# [2022-01-12] Nylas Node.js SDK v6.0.0

Source: https://developer.nylas.com/docs/new/v2-changelogs/2022-01-12-node-sdk-v6-0-0/

The Nylas Node.js SDK v6.0.0 has been released!

- GitHub: [Nylas Node.js SDK](https://github.com/nylas/nylas-nodejs/releases/tag/v6.0.0)
- Distribution: [npm](https://www.npmjs.com/package/nylas/v/6.0.0)

This is a breaking change when upgrading from version 5.X.X. We created a [migration guide](/docs/v2/sdks/upgrade-node/) so you can see what’s different.

We made the SDK more Typescript like and improved the experience for developers. Some of things we fixed are:

- Lack of typing on properties and functions
- Lack of naming consistencies, snake_case vs. camelCase
- No type strictness
- No type checking when instantiating new objects
- Bugs/inconsistencies in deserialization
- Lack of secondary models
