Description of problem: The latest version of tuareg-mode is 2.04 (https://forge.ocamlcore.org/frs/?group_id=43) but the version in repositories is 1.45.6 . Please update the package Version-Release number of selected component (if applicable): 1.45.6
This new version is indeed much better. I've kicked off a build here: http://koji.fedoraproject.org/koji/taskinfo?taskID=3260205
