 **PhantomJS 1.8.1 or later is required for 1.1.**
+#### Support of Gecko, with SlimerJS
+CasperJS can now be launched with [SlimerJS](http://slimerjs.org) instead of PhantomJS.
+It allows you to execute tests with the rendering engine of Firefox. Just launch CasperJS
+with the flag `--engine=slimerjs`.
+SlimerJS 0.8 or later is required.
 #### `require()` in custom modules
 CasperJS 1.1 now internally uses PhantomJS' native `require()` function, but it has side effect if you write your own casperjs modules; in any casperjs module, you now have to use the new global `patchRequire()` function first:

 ### Bugfixes & enhancements
 - heavy lifting of casperjs bootstrap script
+- closed [#482](https://github.com/n1k0/casperjs/issues/482) - support of Gecko (Firefox's engine) with [SlimerJS](http://slimerjs.org): new option --engine=slimerjs (experimental)
 - fixed [#387](https://github.com/n1k0/casperjs/issues/387) - Setting viewport isn't quite synchronous
 - fixed [#410](https://github.com/n1k0/casperjs/issues/410) - trigger `mousedown` and `mousedown` events on click
 - fixed [#433](https://github.com/n1k0/casperjs/issues/433) - `assertField("field", "")` will always pass even though the `field` doesn't exist
