There are a few changes with Grunt 1.0. With this latest release, versions of Node.js 0.8 and beyond will no longer be supported. Other changes include updates to peer dependencies, a new repo to encourage the community to get more involved in moulding and pushing it forward, a hopefully help to expedite the process of getting community contributions into future releases, as well as updates to npm scripts. grunt-cli now comes installed as part of the software , meaning users can skip over the step of npm install grunt-cli -g. According to the official blog, peer dependencies will no longer be installed for users as of npm@3 – users of Grunt plugins will need to use npm install grunt –save-dev alongside any Grunt plugin install.
Further changes to Grunt 1.0 include controls to prevent multiple asynchronous callback attempts, updates to removed duplicate BOM strip code, and alterations to ensure a Grunt bin is created upon installation. Finally, the team advise that there have been some updates to APIs which could potentially cause some breaking changes – notably with CoffeeScript 1.10.0, which could throw up some issues when using the language alongside plugins and Gruntfiles.
