 - Command substitutions now have access to the terminal, allowing tools like `fzf` to work in them (#1362, #3922).
 - `bg`s argument parsing has been reworked. It now fails for invalid arguments but allows non-existent jobs (#3909).
 - `read` now supports the `--silent` flag to hide the characters typed (#838).
+- fish will now reset $USER if the uid is 0. This is to workaround some su implementations that pass along $USER when switching to root (#3944).
