Deprecations and removed features
---------------------------------
- Most ``string`` subcommands no longer append a newline to their input if the input didn't have one (:issue:`8473`, :issue:`3847`)
- Special support for non-standard color sequences has been removed from fish's escape sequence removal. This applies to terminals like the Data General Dasher D220 from 1984. We do not expect anyone to have ever used fish with such a terminal. (:issue:`8769`)
- Fish's escape sequence removal (like for ``string length --visible`` or to figure out how wide the prompt is) no longer has special support for non-standard color sequences like from Data General terminals, e.g. the Data General Dasher D220 from 1984. This removes a bunch of work in the common case, allowing ``string length --visible`` to be much faster with unknown escape sequences. We don't expect anyone to have ever used fish with such a terminal (:issue:`8769`).
- Code to upgrade universal variables from fish before 3.0 has been removed. Users who upgrade directly from fishes before then will have to set their universal variables (including abbreviations) again. (:issue:`8781`)
- The meaning of an empty color variable has changed. Previously, when a variable was empty it would be interpreted as the "normal" color. Now fish will ignore empty color variables and go to the fallback color. For example::
