 * Add new customization variable `cider-font-lock-reader-conditionals` which toggles syntax highlighting of reader conditional expressions based on the buffer connection.
 * Add new face `cider-reader-conditional-face` which is used to mark unused reader conditional expressions.
 * [#1544](https://github.com/clojure-emacs/cider/issues/1544): Add a new defcustom `nrepl-use-ssh-fallback-for-remote-hosts` to control the behavior of `nrepl-connect` (and in turn that of `cider-connect`) for remote hosts.

 By default `company-mode` will provide completion candidates with the assumption
 that whatever you've typed so far (e.g. `map-`) is a completion prefix (meaning
 you'd get only candidates that have `map-` in the beginnings of their names).
+You can get enhanced fuzzy completion with the CIDER-specific completion style
+by adding:
 
-You can get enhanced fuzzy completion with `company-mode` if you install the
-additional package [company-flx](https://github.com/PythonNut/company-flx).
-This is powered internally by [flx](https://github.com/lewang/flx).
+```el
+(add-hook 'cider-repl-mode-hook #'cider-company-enable-fuzzy-completion)
+(add-hook 'cider-mode-hook #'cider-company-enable-fuzzy-completion)
+```
 
-Basically with `company-flx` enabled typing something like `mp` will show you
-`map-indexed` as one of the possible completion candidates.
+Now `company-mode` will accept certain fuzziness when matching candidates
+against the prefix. For example, typing `mp` will show you `map-indexed` as one
+of the possible completion candidates, `cji` will complete to `clojure.java.io`,
+etc. Different completion examples are
+listed [here](https://github.com/alexander-yakushev/compliment/wiki/Examples).
