It makes ``^`` an ordinary character instead of denoting an stderr redirection, to make dealing with quoting and such easier. Use ``2>`` instead. This can no longer be turned off since fish 3.5. The flag can still be tested for compatibility, but a ``no-stderr-nocaret`` value will simply be ignored. -- ``qmark-noglob`` was also introduced in fish 3.0 (and made the default in 4.0). It makes ``?`` an ordinary character instead of a single-character glob. Use a ``*`` instead (which will match multiple characters) or find other ways to match files like ``find``. -- ``regex-easyesc`` was introduced in 3.1. It makes it so the replacement expression in ``string replace -r`` does one fewer round of escaping. Before, to escape a backslash you would have to use ``string replace -ra '([ab])' '\\\\\\\\$1'``. After, just ``'\\\\$1'`` is enough. Check your ``string replace`` calls if you use this anywhere. -- ``ampersand-nobg-in-token`` was introduced in fish 3.4. It makes it so a ``&`` i no longer interpreted as the backgrounding operator in the middle of a token, so dealing with URLs becomes easier. Either put spaces or a semicolon after the ``&``. This is recommended formatting anyway, and ``fish_indent`` will have done it for you already. -- ``remove-percent-self`` turns off the special ``%self`` expansion. It was introduced in 4.0. To get fish's pid, you can use the :envvar:`fish_pid` variable. -- ``test-require-arg`` removes :doc:`builtin test `'s one-argument form (``test "string"``. It was introduced in 4.0. To test if a string is non-empty, use ``test -n "string"``. If disabled, any call to ``test`` that would change sends a :ref:`debug message ` of category "deprecated-test", so starting fish with ``fish --debug=deprecated-test`` can be used to find offending calls. +- ``stderr-nocaret`` was introduced in fish 3.0 and cannot be turned off since fish 3.5.
