 ### Changed
-- Log geckodriver version on startup
+- [`RectResponse`](https://docs.rs/webdriver/0.27.0/webdriver/response/struct.RectResponse.html) permits returning floats for `width` and `height` fields
+- New type [`CookieResponse`](https://docs.rs/webdriver/0.27.0/webdriver/response/struct.CookieResponse.html) for the [`GetNamedCookie` command](https://docs.rs/webdriver/0.27.0/webdriver/command/enum.WebDriverCommand.html#variant.GetNamedCookie) returns a single cookie, as opposed to an array of a single cookie
+- To pick up a prepared profile from the filesystem, it is now possible to pass `["-profile", "/path/to/profile"]` in the `args` array on `moz:firefoxOptions`
+- geckodriver now recommends Firefox 53 and greater

+### Fixed
