# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

## [0.11.1]

### Changed

- Extend the supported engines to node <= 15

## [0.11.0]

### Changed

- Switch from the deprecated `grpc` library to `@grpc/grpc-js`. This
  does not affect the user-facing API.
- Support NodeJS 12. NodeJS 10 is still supported but you are
  encouraged to upgrade as NodeJS 10 will be out of support in April
  2021.
- The source code of this library is now distributed as ES6 rather
  than ES5. This was required by the switch to `@grpc/grpc-js` which
  is also only distributed as ES6. If you use typescript, change the
  target in your own `tsconfig.json` to `es6`.
- All NPM dependencies have been updated to their latest version.
