   This means that on systems where fish version 3.x was installed originally, the update will avoid creating that file (:issue:`12725`).
 - ``fish_hg_prompt``, ``fish_git_prompt`` and ``fish_fossil_prompt`` now strip control characters from VCS state read off disk, matching ``prompt_pwd``.
 - The sample informative and minimalist prompts now use ``prompt_pwd`` instead of printing ``$PWD`` directly.
+- ``bind`` shows the file where bindings were defined (:issue:`12504`).
