Allow docking kitty windows to the edges of other windows or of the tab, for
status bars, file trees, etc. Create them with launch --type=window-dock
or launch --type=tab-dock, see Docked windows
A new option restore_session_after_logout to save the state of every
kitty instance, including scrollback, when logging out, restarting or
shutting down and restore it the next time kitty starts. On macOS, the state
is encrypted with a key in the keychain. On Linux, it requires the Inhibit
desktop portal. See Restoring kitty after logging out (#1197, #10659)
Allow using tabs like named workspaces: A new launch --focus-existing
option to focus an existing window or tab instead of creating a new one, a
new by-title value for launch --location to keep tabs in
alphabetical order and new options for kitten @ detach-window and the
detach_window action to send windows to a named tab, creating it if
needed (#10627)
Wayland: The client side window decorations used on compositors such as
GNOME now look like native GNOME decorations and follow the desktop titlebar
font, text scaling, button layout and titlebar click action settings
(#10766)
Wayland: Support touchscreens. A tap is a click, a finger that moves scrolls
with momentum, and a finger held still before it moves selects text
(#5432, #10551)
Custom shaders: New cursor-trail-railgun, cursor-trail-torpedo
and cursor-trail-pixiedust shaders that make particles fly off the
cursor as it moves, in the style of neovide. Shaders can now be controlled
with key presses via the new shader_event action (see
Controlling shaders with key presses), can be faded in and out, reversed and looped
with new animation_* pipeline directives and can define a
pointer_map() function so that clicks and selections land on the
text shown under the mouse, which the crt shader now uses, see
Shaders that move content. Also fix animations becoming jerky after
kitty has been running for a few hours, shaders specified by path not being
found and various pipeline bugs (#10587, #10667, #10693,
#10595, #10694, #10639)
Graphics protocol: Add two new indexed color image formats whose pixels are indices into the terminal color
palette, so that images change color along with the color scheme, and allow
clients to detect support for individual protocol features, such as
animation and Unicode placeholders, via the new e query key, see
Querying support for protocol features (#9379, #10732)
Support the Program Status Protocol (OSC 7501) that lets
programs report whether they are working, finished, failed or blocked waiting
on the user. Shown in the tab bar via a new tab.program_status field
for tab_title_template, see Reporting the status of a program
Automatic color themes: When the system switches
between light and dark, keep colors set by programs running in a window, by
the ssh kitten, by launch --color
or launch --copy-colors, and use the current theme colors when a
program restores its saved colors. launch --color colors now also
survive config reloads. The ssh kitten can use different color schemes for
remote hosts in dark and light mode via the new
kitten-ssh.color_scheme_dark, kitten-ssh.color_scheme_light and
kitten-ssh.color_scheme_no_preference options (#10724)
Layouts: Align the borders of neighboring windows and keep the gaps between
them uniform, and add a new option collapse_window_margins to have
the margins of neighboring windows collapse into each other instead of
adding up (#10508)
Window resizing: A new --strategy=edge mode to select and move a
specific internal divider in the Splits layout, and hold Alt with a
resize letter to take a fraction of the remaining resize steps, configurable
with the new --fraction option
Scale the thickness of box drawing characters, cursors and the window title
bar border with the font size, so they no longer look too thin when zoomed in
or too thick when zoomed out. At the configured font_size nothing
changes (#10362)
mouse_map can now map the scroll wheel, via
the wheel_up, wheel_down, wheel_left and
wheel_right buttons, for example, to change the font size with
Ctrl+scroll
A new option hyperlink_target_position to control where the URL shown
by show_hyperlink_targets is displayed, including as a browser style
tooltip next to the mouse cursor (#10770)
Show the hand pointer and hover highlighting over links only when the pressed
modifiers match a configured mouse action for opening the link with a single
click, updating immediately when modifiers are pressed or released
quick-access-terminal kitten: New
kitty +kitten quick_access_terminal --if-running,
kitty +kitten quick_access_terminal --listen-on and
kitty +kitten quick_access_terminal --hold options to run programs
in an already running quick access terminal, use a fixed remote control
socket and keep the terminal open after the program exits (#10603)
Sessions: A new os_window_position keyword and a new
--os-window-geometry option for save_as_session to save the size,
position and state of OS Windows in session files. Also fix the OS Window
size and os_window_title in sessions sometimes being ignored
(#10675)
Command palette: Show action and kitten aliases at the top when the search
query is empty, so they can be used to pin frequently used actions (#10711)
Vertical tab bars: When tab_title_max_length is set, size the tab bar
to fit the decorations of the current tab_bar_style, allowing much
narrower tab bars (#10680)
Linux/BSD: Detect MIME types for open actions and
kittens using the shared-mime-info cache, matching the rest of the desktop,
including files without an extension, such as Makefile, and MIME
type aliases (#3056)
IME: Keep the candidate window anchored at the start of the pre-edit text
and at the cursor, so it no longer jumps around while composing text. On
macOS, commit in-progress IME or dictation text instead of discarding it when
the OS window loses focus (#10642, #10644)
Shell integration: Make the kitty terminfo files available in commands run
via run0, similar to sudo (#10692)
kitty --config=NONE now also skips the automatic color theme
files, open-actions.conf, launch-actions.conf,
mime.types, paste-actions.py, notifications.py and
the custom window icon in the kitty config directory
Processes kitty inserts to wrap the program it runs, such as
/usr/bin/login on macOS or the wrapper for launch --hold,
are now skipped when reporting the pid, working directory, command line and
environment of a window in kitten @ ls and when matching
windows. Also fix launch --cwd=root using the working
directory of the foreground process instead of the root process while the
shell is running a command
Nightly builds now show the date and hash of the commit they were built from
in the output of kitty --version and kitten --version
Do not render between render frames to reduce flicker from programs that draw
with many small partial updates (#10749)
Performance: Faster growing of the GPU sprite cache, particularly on macOS,
less CPU usage with a non-zero input_delay and no continuous
re-rendering when a selection is present and the window is scrolled back
(#10714)
Remote control: Fix a crafted request being able to bypass password based
remote control authentication by masquerading as a cancellation of an
asynchronous request
Remote control: Fix many commands, including action, send-key,
set-colors, set-background-opacity, set-font-size, ls,
run and set-enabled-layouts, ignoring options, reporting false
success or silently misinterpreting invalid input, particularly when used in
remote_control mappings. set-colors now parses color files the same
way as kitty.conf. Also fix a single unresponsive peer blocking all
remote control communication and a crash when using damaged images with
set-window-logo or set-background-image (#10672,
#10632, #10688, #10690, #10715)
Fix various terminal emulation bugs, including in origin mode cursor
position reports, erasing multicell characters, the CHT escape code and
copying text containing tabs, wide characters being drawn on the wrong row
after colliding with scaled text, emoji sequences being split into multiple
cells when wrapped, text typed into a new window before the program is ready
sometimes being garbled, as well as a heap buffer overflow, an out of bounds
write and a use-after-free when reloading the config (#10609,
#10729, #10632, #10682, #10767)
Graphics protocol: Allow shared memory object names without a leading slash
again, for sandboxed macOS applications, and fix various bugs with animation
frames and Unicode placeholders (#10684, #10599, #10632)
Fix various window and tab management bugs, with focus moving to the wrong
window on close, drag and drop onto title bars, visual window selection,
Grid layout placement, title bar padding and tab titles being truncated too
early. detach_tab now shows custom titles in the OS Window chooser
(#10640)
Fix render jitter when scrolled back with a partial line and the client is
using the synchronised rendering escape code (#10794)
Fix bold or italic Nerd Font icons sometimes being rendered using glyphs
from an unrelated font, the cursor trail not always being shown when focus
moves to a different window, watcher entries not being removed on
config reload and changing text marker colors at runtime, for example with
kitten @ set-colors or automatic theme switching, applying the colors
of each marker to the next one (#10591)
ssh kitten: Preserve the permissions of copied directories, fix copying
files outside HOME whose paths share its prefix and files in HOME being
copied to an absolute path with --symlink-strategy=resolve when HOME
is a symlink, fix hanging when re-using a shared connection that has
silently died and fix colors 16-255 being set to white with themes that do
not define them (#10691, #10661, #10727, #10737)
Desktop UI kitten: Fix D-Bus activation when kitten is installed in a path
containing spaces or quoting characters (#10784)
Automatic color themes: Stop using cached colors and background images after
the corresponding theme file has been deleted and apply theme files created
after kitty was started when reloading the config (#10786)
Themes kitten: Fix overwriting the Unicode input kitten’s recent entries
and input mode, and vice versa, by using separate caches (#10780)
Remote file kitten: Preserve the local edited copy and show its recovery path
when the final upload fails, including when the SSH connection has died
(#10789)
Transfer kitten: When receiving files, replace existing symbolic and hard
links at the destination instead of overwriting the files they point to, and
write to a temporary file that is renamed into place, so an interrupted
transfer no longer leaves a truncated file behind (#10713)
Drag and drop kitten: Reject copying or moving a directory into itself or
one of its subdirectories, and moving a directory into a symlink that points
inside it, which would delete the moved files. When moving, do not delete
sources that were replaced during the drop, for example by files merged
through a symlink in the destination. Respect overwrite
confirmation for case and Unicode equivalent names on filesystems that treat them as aliases, list the
existing files that will be overwritten under their actual names, including
inside symlinked directories, and fix dropping a directory over an existing
file. No longer rename remotely dropped files whose names differ only in case
on case sensitive filesystems (#10769, #10772)
Drag and drop protocol: Fix base64 data with padding at the end being
rejected, as allowed by the protocol (#10777)
Clipboard kitten: Fix only the last of several outputs that use the same
MIME type being saved, for example with
kitten clipboard -g picture.png picture.jpg, the data is now
downloaded and decoded only once for all such outputs. Reject duplicate
output files, including ones that differ only in case on case-insensitive
filesystems or whose paths contain a symlink followed by ... Fix a race
when replacing an existing output file, losing the original file if writing
it fails and kitten clipboard -g -m . formats.txt silently doing
nothing. Also preserve the permissions of and follow symlinks at existing
output files (#10738, #10744)
Kittens: When saving files, such as themes, config files or clipboard
output, write to the target of a symlink even when the target does not yet
exist, instead of replacing the symlink with a regular file (#10740)
Kittens: Fix laggy mouse selection and failures comparing remote
directories in the diff kitten, Unicode quotes not being removed from around
paths and URLs in the hints kitten, the order of styles with negative or
closely spaced fractional axis values in the choose-fonts kitten, various
bugs in the choose-files, quick-access-terminal and other kittens and reject
command-line options missing their required value (#10634,
#10641, #10676, #10687, #10730)
Wayland: Fix a crash on compositors without cursor-shape support, kitty
being disconnected by GNOME when showing a long covered window, the app_id
being lost when hiding and showing windows, kitty –os-window-tag
not setting the window tag and various drag and drop bugs (#10597,
#10602, #10604, #10759, #10632)
Linux: Fix momentum scrolling up or left, X11 wheel events from sources
without smooth scrolling being ignored and various desktop notification
bugs. Notifications now identify kitty’s desktop file, so desktops such as
KDE can group them (#10625, #10695, #10610,
#10721)
macOS: Fix padding rendering black after sleep, OS windows not staying on all
spaces, a duplicate path when dropping items from Apple Mail, emoji from a
monochrome emoji font such as Noto Emoji not using the foreground color, a
memory leak, reloading config causing Apple injected shortcuts to not work
and kitty freezing when opening a new window while another entry
in /dev is stuck (#10708, #10581, #10628,
#10673, #10741, #10757, #10793)
zsh: Respect the user’s descriptions format style for completion group
headings, fixing literal %B markers appearing with fzf-tab, and fix a
“maximum nested function level reached” error at every prompt after
interrupting a command run at shell startup, for example via a session file
(#10748, #10768)
