The update includes support for Meteor development on Windows machines for the first time, meaning developers using WIndows 7, 8.1, Server 2008 and 2012 can now develop using the platform. A native installer includes the Meteor SDK, Node.js binaries and MongoDB.
Meteor 1.1 also adds support for MongoDB 3.0, which brought significant performance and scalability improvements.
The team says that Meteor 1.1 is fully compatible with 1.0 so upgrading should be a breeze, and the core stack contains a number of improvements that should make development using the language easier.
