To update |kitty|, :doc:`follow the instructions <binary>`.
.. recent major features {{{
Recent major new features
---------------------------
File transfer over the tty device
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Transfer files to and from remote computers over the ``TTY`` device itself.
This means that file transfer works over nested SSH sessions, serial links,
etc. Anywhere you have a terminal device, you can transfer files.
Simply ssh into a remote computer using the :doc:`ssh kitten </kittens/ssh>`
and run the :doc:`transfer kitten </kittens/transfer>` (which the ssh kitten
makes available for you on the remote computer automatically). For example, to
copy a file from a remote computer::
<local computer> $ kitten ssh my-remote-computer
<remote computer> $ kitten transfer some-file /path/on/local/computer
The kitten can transfer files to and from the remote computer. It supports
recursive transfer of directories, symlinks and hardlinks. It can even use the
rsync algorithm to speed up repeated transfers of large files.
Truly convenient SSH
~~~~~~~~~~~~~~~~~~~~~~~~
The :doc:`ssh kitten <kittens/ssh>` is redesigned with powerful new features:
* Automatic :ref:`shell_integration` on remote machines
* Easily :ref:`clone local shell/editor config <real_world_ssh_kitten_config>` on remote machines
* Easily :ref:`edit files in your local editor <edit_file>` on remote machines
* Automatic :opt:`re-use of existing connections <kitten-ssh.share_connections>` to avoid connection setup latency

switch to the previously used window layout (:iss:`870`)
- New ``neighboring_window`` and ``move_window`` functions to switch to
neighboring windows in the current layout, and move them around, similar to
window movement in vim (:iss:`916`)
- A new ``pipe`` function that can be used to pipe the contents of the screen
and scrollback buffer to any desired program running in a new window, tab or
overlay window. (:iss:`933`)
- Add a new :option:`kitty --start-as` command line flag to start kitty
full-screen/maximized/minimized. This replaces the ``--start-in-fullscreen``
flag introduced in the previous release (:iss:`935`)
- When mapping the ``new_tab`` action allow specifying that the tab should open
next to the current tab instead of at the end of the tabs list (:iss:`979`)

on macs thicker, which makes it similar to the result of
sub-pixel antialiasing (:pull:`950`)
- macOS: Add an option :opt:`macos_traditional_fullscreen` to make

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Preserve the mouse selection even when the contents of the screen are
scrolled or overwritten provided the new text does not intersect the
selected lines.
- Linux: Implement support for Input Method Extensions (multilingual input
using standard keyboards) via `IBus
<https://github.com/ibus/ibus/wiki/ReadMe>`_ (:iss:`469`)
- Implement completion for the kitty command in bash and zsh. See
:ref:`shell_integration`.

from kitty.conf
- Add an action to the ``clear_terminal`` function to scroll the screen
contents into the scrollback buffer (:iss:`1113`)

(:iss:`754`)
- Fix detection of URLs in HTML source code (URLs inside quotes) (:iss:`785`)
- Implement support for emoji skin tone modifiers (:iss:`787`)
- Round-trip the zwj unicode character. Rendering of sequences containing zwj
is still not implemented, since it can cause the collapse of an unbounded
number of characters into a single cell. However, kitty at least preserves
the zwj by storing it as a combining character.
- macOS: Disable the custom mouse cursor. Using a custom cursor fails on dual
GPU machines. I give up, Apple users will just have to live with the
limitations of their choice of OS. (:iss:`794`)
- macOS: Fix control+tab key combination not working (:iss:`801`)
- Linux: Fix slow startup on some systems caused by GLFW searching for
joysticks. Since kitty does not use joysticks, disable joystick support.

into neighboring windows, the selection is still updated (:pull:`624`)
- When clicking in the margin/border area of a window, map the click to the
nearest cell in the window. Avoids selection with the mouse failing when
starting the selection just outside the window.
- When drag-scrolling stop the scroll when the mouse button is released.
- Fix a regression in the previous release that caused pasting large amounts
of text to be duplicated (:iss:`709`)

texture cache on the GPU, further reducing overall resource usage. Use
the shortcut `ctrl+shift+n` to open a new top-level window.
- Add support for a *daemon* mode using the `--single-instance` command line
option. With this option you can have only a single kitty instance running.
All future invocations simply open new top-level windows in the existing
instance.
- Support colored emoji
- Use CoreText instead of FreeType to render text on macOS
- Support running on the "low power" GPU on dual GPU macOS machines
- Add a new "grid" window layout
- Drop the dependency on glfw (kitty now uses a modified, bundled copy of glfw)
- Add an option to control the audio bell volume on X11 systems
- Add a command line switch to set the name part of the WM_CLASS window
property independently.
- Add a command line switch to set the window title.
- Add more options to customize the tab-bar's appearance (font styles and
separator)
- Allow drag and drop of files into kitty. On drop kitty will paste the
file path to the running program.
- Add an option to control the underline style for URL highlighting on hover
- X11: Set the WINDOWID environment variable
- Fix middle and right buttons swapped when sending mouse events to child
processes
- Allow selecting in a rectangle by holding down Ctrl+Alt while dragging with
the mouse.
0.5.1 [2017-12-01]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Add an option to control the thickness of lines in box drawing characters
- Increase max. allowed ligature length to nine characters
- Fix text not vertically centered when adjusting line height
- Fix unicode block characters not being rendered properly
- Fix shift+up/down not generating correct escape codes
- Image display: Fix displaying images taller than two screen heights not
scrolling properly
0.5.0 [2017-11-19]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Add support for ligature fonts such as Fira Code, Hasklig, etc. kitty now
uses harfbuzz for text shaping which allow it to support advanced OpenType
features such as contextual alternates/ligatures/combining glyphs/etc.
- Make it easy to select fonts by allowing listing of monospace fonts using:
kitty list-fonts
- Add an option to have window focus follow mouse
- Add a keyboard shortcut (ctrl+shift+f11) to toggle fullscreen mode
- macOS: Fix handling of option key. It now behaves just like the alt key on
Linux. There is an option to make it type unicode characters instead.
- Linux: Add support for startup notification on X11 desktops. kitty will
now inform the window manager when its startup is complete.
- Fix shell prompt being duplicated when window is resized
- Fix crash when displaying more than 64 images in the same session
- Add support for colons in SGR color codes. These are generated by some
applications such as neovim when they mistakenly identify kitty as a libvte
based terminal.
- Fix mouse interaction not working in apps using obsolete mouse interaction
protocols
- Linux: no longer require glew as a dependency
0.4.2 [2017-10-23]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Fix a regression in 0.4.0 that broke custom key mappings
- Fix a regression in 0.4.0 that broke support for non-QWERTY keyboard layouts
- Avoid using threads to reap zombie child processes. Also prevent kitty from
hanging if the open program hangs when clicking on a URL.
0.4.0 [2017-10-22]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Support for drawing arbitrary raster graphics (images) in the terminal via a
new graphics protocol. kitty can draw images with full 32-bit color using both
ssh connections and files/shared memory (when available) for better
performance. The drawing primitives support alpha blending and z-index.
Images can be drawn both above and below text. See :doc:`graphics-protocol`.
for details.
- Refactor kitty's internals to make it even faster and more efficient. The CPU
usage of kitty + X server while doing intensive tasks such as scrolling a
file continuously in less has been reduced by 50%. There are now two
configuration options ``repaint_delay`` and ``input_delay`` you can use to
fine tune kitty's performance vs CPU usage profile. The CPU usage of kitty +
X when scrolling in less is now significantly better than most (all?) other
terminals. See :doc:`performance`.
- Hovering over URLs with the mouse now underlines them to indicate they
can be clicked. Hold down Ctrl+Shift while clicking to open the URL.
- Selection using the mouse is now more intelligent. It does not add
blank cells (i.e. cells that have no content) after the end of text in a
line to the selection.
- The block cursor in now fully opaque but renders the character under it in
the background color, for enhanced visibility.
- Allow combining multiple independent actions into a single shortcut
- Add a new shortcut to pass the current selection to an external program
- Allow creating shortcuts to open new windows running arbitrary commands. You
can also pass the current selection to the command as an arguments and the
contents of the screen + scrollback buffer as stdin to the command.
