 Unreleased
 ----------
 
+- Fix parsing of the `<=` operator in *blang* expressions of `dune` files.
+  Previously, the operator would be interpreted as `,`. (#6928, @tatchi)
+
 - Fix `--trace-file` output. Dune now emits a single *complete* event for every
   executed process. Unterminated *async* events are no longer written. (#6892,
   @rgrinberg)
