 * [#302](https://github.com/clojure-emacs/clojure-mode/pull/302): Add new sexp navigation commands. `clojure-forward-logical-sexp` and `clojure-backward-logical-sexp` consider `^hints` and `#reader.macros` to be part of the sexp that follows them.
 * [#303](https://github.com/clojure-emacs/clojure-mode/issues/303): Handle `boot` projects in `clojure-expected-ns`.
+* Added dedicated modes for ClojureScript, ClojureC and ClojureX. All of them are derived from `clojure-mode`.
