Notable fixes and improvements

• Jobs running in the background can now be removed from the list of jobs with the new disown builtin, which behaves like the same command in other shells (#2810).
• Command substitutions now have access to the terminal, like in other shells. This allows tools like fzf to work properly (#1362, #3922).
• In cases where the operating system does not report the size of the terminal, the COLUMNS and LINES environment variables are used; if they are unset, a default of 80x24 is assumed.
• New French (#3772 & #3788) and improved German (#3834) translations.
• fish no longer depends on the which external command.

Other significant changes

• Performance improvements in launching processes, including major reductions in signal blocking. Although this has been heavily tested, it may cause problems in some circumstances; set the FISH_NO_SIGNAL_BLOCK variable to 0 in your fish configuration file to return to the old behaviour (#2007).
• Performance improvements in prompts and functions that set lots of colours (#3793).
• The Delete key no longer deletes backwards (a regression in 2.5.0).
• functions supports a new --details option, which identifies where the function was loaded from (#3295), and a --details --verbose option which includes the function description (#597).
• read will read up to 10 MiB by default, leaving the target variable empty and exiting with status 122 if the line is too long. You can set a different limit with the FISH_READ_BYTE_LIMIT variable.
• read supports a new --silent option to hide the characters typed (#838), for when reading sensitive data from the terminal. read also now accepts simple strings for the prompt (rather than scripts) with the new -P and --prompt-str options (#802).
• export and setenv now understand colon-separated PATH, CDPATH and MANPATH variables.
• bind supports a new --list-modes option (#3872).
• bg will check all of its arguments before backgrounding any jobs; any invalid arguments will cause a failure, but non-existent (eg recently exited) jobs are ignored (#3909).
• funced warns if the function being edited has not been modified (#3961).
• printf correctly outputs "long long" integers (#3352).
• status supports a new current-function subcommand to print the current function name (#1743).
• string supports a new repeat subcommand (#3864). string match supports a new --entire option to emit the entire line matched by a pattern (#3957). string replace supports a new --filter option to only emit lines which underwent a replacement (#3348).
• test supports the -k option to test for sticky bits (#733).
• umask understands symbolic modes (#738).
• Empty components in the CDPATH, MANPATH and PATH variables are now converted to "." (#2106, #3914).
• New versions of ncurses (6.0 and up) wipe terminal scrollback buffers with certain commands; the C-l binding tries to avoid this (#2855).
• Some systems' su implementations do not set the USER environment variable; it is now reset for root users (#3916).
• Under terminals which support it, bracketed paste is enabled, escaping problematic characters for security and convience (#3871). Inside single quotes ('), single quotes and backslashes in pasted text are escaped (#967). The fish_clipboard_paste function (bound to C-v by default) is still the recommended pasting method where possible as it includes this functionality and more.
• Processes in pipelines are no longer signalled as soon as one command in the pipeline has completed (#1926). This behaviour matches other shells mre closely.
• All functions requiring Python work with whichever version of Python is installed (#3970). Python 3 is preferred, but Python 2.6 remains the minimum version required.
• The color of the cancellation character can be controlled by the fish_color_cancel variable (#3963).
• Added completions for:
• caddy (#4008)
• castnow (#3744)
• climate (#3760)
• flatpak
• gradle (#3859)
• gsettings (#4001)
