Release Notes

WickyNilliams/headroom.js

### [`v0.12.0`](https://togithub.com/WickyNilliams/headroom.js/compare/v0.11.0...v0.12.0) [Compare Source](https://togithub.com/WickyNilliams/headroom.js/compare/v0.11.0...v0.12.0) ### [`v0.11.0`](https://togithub.com/WickyNilliams/headroom.js/releases/tag/v0.11.0) [Compare Source](https://togithub.com/WickyNilliams/headroom.js/compare/v0.10.4...v0.11.0) This release adds support for multiple classes. This can be of particular use when using atomic CSS classes. To use, pass a string with a space-separated list of classes in your options: ```js const hr = new Headroom(element, { classes: { pinned: "first-class second-class", unpinned: "third-class fourth-class" } }); hr.init(); ``` ### [`v0.10.4`](https://togithub.com/WickyNilliams/headroom.js/releases/tag/v0.10.4) [Compare Source](https://togithub.com/WickyNilliams/headroom.js/compare/v0.10.3...v0.10.4) This release fixes a bug where classes such as `top` were not added when Headroom is initialised, only after the user first scrolls. ### [`v0.10.3`](https://togithub.com/WickyNilliams/headroom.js/releases/tag/v0.10.3) [Compare Source](https://togithub.com/WickyNilliams/headroom.js/compare/v0.10.2...v0.10.3) This release contains a breaking change for IE11, with the introduction of `Object.assign`. Please be aware this needs to be polyfilled if you wish to support IE11. Alternatively, you can wrap your initialisation code in a condition to avoid instantiation on unsupported browsers: ```js if(Headroom.cutsTheMustard) { // initialise headroom } ``` ### [`v0.10.2`](https://togithub.com/WickyNilliams/headroom.js/compare/v0.10.0...v0.10.2) [Compare Source](https://togithub.com/WickyNilliams/headroom.js/compare/v0.10.0...v0.10.2) ### [`v0.10.0`](https://togithub.com/WickyNilliams/headroom.js/compare/v0.9.4...v0.10.0) [Compare Source](https://togithub.com/WickyNilliams/headroom.js/compare/v0.9.4...v0.10.0)
