Performance improvements

• Colorized output is now significantly faster, see #720 and #853 (@tavianator)
• Writing to stdout is now buffered if the output does not go to a TTY. This increases performance when the output of fd is piped to another program or to a file, see #885 (@tmccombs, original implementation by @sourlemon207)
• File metadata is now cached between the different filters that require it (e.g. --owner, --size), reducing the number of stat syscalls when multiple filters are used; see #863 (@tavianator, original implementation by @alexmaco)

Features

• Don't buffer command output from --exec when using a single thread. See #522
• Add new -q, --quiet flag, see #303 (@Asha20)
• Add new --no-ignore-parent flag, see #787 (@will459)
• Add new --batch-size flag, see #410 (@devonhollowood)
• Add opposing command-line options, see #595 (@Asha20)
• Add support for more filesystem indicators in LS_COLORS, see https://github.com/sharkdp/lscolors/pull/35 (@tavianator)

Bugfixes

• Always show the ./ prefix for search results unless the output is a TTY or --strip-cwd-prefix is set, see #760 and #861 (@jcaplan)
• Set default path separator to / in MSYS, see #537 and #730 (@aswild)
• fd cannot search files under a RAM disk, see #752
• fd doesn't show substituted drive on Windows, see #365
• Properly handle write errors to devices that are full, see #737
• Use local time zone for time functions (--change-newer-than, --change-older-than), see #631 (@jacobmischka)
• Support --list-details on more platforms (like BusyBox), see #783
• The filters --owner, --size, and --changed-{within,before} now apply to symbolic links themselves, rather than the link target, except when --follow is specified; see #863
• Change time comparisons to be exclusive, see #794 (@jacobmischka)

Changes

• Apply custom --path-separator to commands run with --exec(-batch) and --list-details, see #697 (@aswild)

Other

• Many documentation updates
