[View Changelog](https://github.com/Leaflet/Leaflet/blob/master/CHANGELOG.md) Note that the master version can contain incompatible changes, so please read the changelog carefully when upgrading to it. ### Using a Hosted Version of Leaflet The latest stable release of Leaflet is hosted on a CDN — to start using it straight away, place this code in the `head` section of your HTML: ### Building Leaflet from the Source Leaflet build system is powered by the [Node.js](http://nodejs.org) platform and Jake, JSHint and UglifyJS libraries, which install easily and work well across all major platforms. Here are the steps to install it: 1. [Download and install Node](http://nodejs.org) 2. Run the following commands in the command line:
npm install -g jake
npm install jshint
npm install uglify-js
Now that you have everything installed, run `jake` inside the Leaflet directory. This will check Leaflet source files for JavaScript errors and inconsistencies, and then combine and compress it to the `dist` folder. ### Building a Custom Version of Leaflet To make a custom build of the library with only the things you need, open `build/build.html` page of the package contents, choose the components (it figures out dependencies for you) and then run the command generated with it.
