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`)

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.
(:iss:`830`)
0.11.3 [2018-07-10]
------------------------------
- Draw only the minimum borders needed for inactive windows. That is only the borders

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`)

window before quitting (:iss:`630`)
- diff kitten: Allow theming the selection background/foreground as well
- diff kitten: Display CRLF line endings using the unicode return symbol
instead of <d> as it is less intrusive (:iss:`638`)

(:iss:`408`)
- When viewing the scrollback in less using :sc:`show_scrollback` and kitty
is currently scrolled, position the scrollback in less to match kitty's
scroll position. (:iss:`148`)
- ssh kitten: Support all SSH options. It can now be aliased directly to ssh
for convenience. (:pull:`591`)
- icat kitten: Add :option:`kitty +kitten icat --print-window-size` to easily
detect the window size in pixels from scripting languages (:iss:`581`)

- Add a "fat" layout that is similar to the "tall" layout but vertically
oriented.

By default only writing is allowed. This feature is supported in many
terminals, search for `OSC 52 clipboard` to find out more about using it.
- Fix moving cursor outside a defined page area incorrectly causing the cursor

the window is not the currently focused window
- Change the window border color if a bell occurs in an unfocused window. Can
be disabled by setting the bell_border_color to be the same as the
inactive_border_color.
- macOS: Add support for dead keys
- Unicode input: When searching by name search for prefix matches as well as
whole word matches

buffer not working correctly if kitty is itself scrolled up.
- Fix window focus gained/lost events not being reported to child programs when
switching windows/tabs using the various keyboard shortcuts.

execute commands instead of just passing the commands as arguments.
0.9.0 [2018-04-15]
------------------------------
- A new kitty command shell to allow controlling kitty via commands. Press
`ctrl+shift+escape` to run the shell.

can use it to select word, paths, filenames, lines, etc. from the screen.
These can be inserted into the terminal, copied to clipboard or sent to
external programs.
- Linux: Switch to libxkbcommon for keyboard handling. It allows kitty to
support XCompose and dead keys and also react to keyboard remapping/layout
change without needing a restart.
- Add support for multiple-key-sequence shortcuts
- A new remote control command `set-colors` to change the current and/or
configured colors.
- When double-clicking to select a word, select words that continue onto the
next/prev line as well.
- Add an `include` directive for the config files to read multiple config files
- Improve mouse selection for windows with padding. Moving the mouse into the
padding area now acts as if the mouse is over the nearest cell.
- Allow setting all 256 terminal colors in the config file
- Fix using `kitty --single-instance` to open a new window in a running kitty
instance, not respecting the `--directory` flag
- URL hints: Exclude trailing punctuation from URLs
- URL hints: Launch the browser from the kitty parent process rather than the
hints kitten. Fixes launching on some systems where xdg-open doesn't like
being run from a kitten.
- Allow using rectangle select mode by pressing shift in addition to the
rectangle select modifiers even when the terminal program has grabbed the
mouse.
0.8.4 [2018-03-31]

and padding of the window.
- Add some non standard terminfo capabilities used by neovim and tmux.
- Fix large drop in performance when using multiple top-level windows on macOS
- Fix save/restore of window sizes not working correctly.

texture cache on the GPU, further reducing overall resource usage. Use
the shortcut `ctrl+shift+n` to open a new top-level window.

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

- 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.
