## [6.0.0](https://www.github.com/googleapis/nodejs-datastore/compare/v5.1.0...v6.0.0) (2020-05-27)


### ⚠ BREAKING CHANGES

* The `Datastore.projectId` property has been removed, and replaced with an asynchronous `getProjectid()` method.  The projectId cannot be determined synchronously, so the previous approach was to use a `{{projectId}}` string placeholder if the projectId had not yet been acquired.  This made it difficult to know exactly when the property would be defined.  
* The library now supports Node.js v10+. The last version to support Node.js v8 is tagged legacy-8 on NPM.

### Features

* add async getProjectId method ([#657](https://www.github.com/googleapis/nodejs-datastore/issues/657)) ([2a7e034](https://www.github.com/googleapis/nodejs-datastore/commit/2a7e034e60f54100c5773d2d4dbe4dec6a721689))

## v3.0.0

01-14-2019 20:31 PST

**This release has breaking changes!** The import style of this library has changed to be consistent with [es modules](https://hacks.mozilla.org/2018/03/es-modules-a-cartoon-deep-dive/).

#### Old busted code
```js
const Datastore = require('@google-cloud/datastore')();
// or...
const Datastore = require('@google-cloud/datastore');
const ds = new Datastore();
```

#### New hot code
```js
const {Datastore} = require('@google-cloud/datastore');
const ds = new Datastore();
```

Please take care to update your imports accordingly!
