## Version 1.0.0

Dynamoose version 1.0.0 is here. This is a **massive** release, and will also be the first official breaking update to Dynamoose. You can view the details about the release below.

This version officially removes support for Node.js versions below 8.0. Versions below 8.0 _might_ work, but we do not make guarantees. Even if Node.js versions below 8.0 work with Dynamoose 1.0+ we might add features that break support for older Node.js versions _without_ a SEMVER major version release.

The one major thing about the release notes below that is a bit confusing is the fact that `ES6/Future Changes` are in the `Breaking changes` section. That section is directly related to `Requiring Node.js version 8.0 and higher`. Therefor although the breaking change is technically the fact that Node.js versions less than 8.0 won't be supported, they are directly related, therefor they are both in the `Breaking changes` section. In future 1.x we might add more ES6/Future Changes, but those will not be considered breaking changes due to the fact that it will only break if you are running on a Node.js version less than version 8.0.

Please comment or [contact me](https://charlie.fish/contact) if you have any questions about this release.
