+## [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.
+
