Clojure CLI versions are not Clojure versions. See [https://clojure.org/releases/tools](https://clojure.org/releases/tools) for Clojure CLI versions.

The Clojure CLI can use _any_ version of Clojure: you specify `org.clojure/clojure` as a dependency and you can even use Clojure 1.0 with the latest Clojure CLI:

```auto
(! 622)-> clojure -Sdescribe
{:version "1.10.1.727" <==== THIS IS THE CLOJURE CLI VERSION
 :config-files ["/usr/local/Cellar/clojure@1.10.1.727/1.10.1.727/deps.edn" "/Users/sean/.clojure/deps.edn" "deps.edn"]
 :config-user "/Users/sean/.clojure/deps.edn"
 :config-project "deps.edn"
 :install-dir "/usr/local/Cellar/clojure@1.10.1.727/1.10.1.727"
 :config-dir "/Users/sean/.clojure"
 :cache-dir ".cpcache"
 :force false
 :repro false
 :main-aliases ""
 :repl-aliases ""}

```

You can install a specific version of the Clojure CLI. I use `brew` on macOS and Linux, for example:

```auto
brew install clojure/tools/clojure@1.10.1.727

```

Several projects out there now rely on the changed `-M` behavior or the new `-X` option on the CLI, which is why they say you need at least 1.10.1.697.
