I was looking for documentation of volatile! etc., but I came up short.

There is some information in the Jira ticket https://clojure.atlassian.net/browse/CLJ-1512 (opening statement clarified by Fogus), and some additional flavor was contributed in the form of an unusually vivid question about the needs of stateful transducers in https://clojure.atlassian.net/browse/CLJ-2146.

Java also has something called "volatile", which is described (for example) at https://docs.oracle.com/javase/tutorial/essential/concurrency/atomic.html. But Clojure's docstrings do not refer to Java's concept, which they easily could do if it were similar.

Does Clojure have official documentation about volatile!?

Clojure’s use does build on Java’s volatiles so the name is intentional.

The only other place I can think of where it’s documented is in the release notes https://github.com/clojure/clojure/blob/master/changes.md#21-transducers

It’s considered kind of an advanced tool so it’s intentionally not front and center. Could probably be mentioned in the transducer docs as an impl tool.
