Release 1.9.2

Changed
-------

* PGO helper scripts no longer set `LC_CTYPE=en_US.UTF-8`. But, note
  that “full” PGO builds still **require** an UTF-8 locale; you need
  to set one manually in your build script
  (https://codeberg.org/dnkl/foot/issues/728).

Release 1.9.1

Added
-----

* Warn when it appears the primary font is not monospaced. Can be
  disabled by setting `[tweak].font-monospace-warn=no`
  (https://codeberg.org/dnkl/foot/issues/704).
* PGO build scripts, in the `pgo` directory. See INSTALL.md -
  _Performance optimized, PGO_, for details
  (https://codeberg.org/dnkl/foot/issues/701).
* Braille characters (U+2800 - U+28FF) are now rendered by foot
  itself (https://codeberg.org/dnkl/foot/issues/702).
* `-e` command-line option. This option is simply ignored, to appease
  program launchers that blindly pass `-e` to any terminal emulator
  (https://codeberg.org/dnkl/foot/issues/184).

Changed
-------

* `-Ddefault-terminfo` is now also applied to the generated terminfo
  definitions when `-Dterminfo=enabled`.
* `-Dcustom-terminfo-install-location` no longer accepts `no` as a
  special value, to disable exporting `TERMINFO`. To achieve the same
  result, simply don’t set it at all. If it _is_ set, `TERMINFO` is
  still exported, like before.
* The default install location for the terminfo definitions have been
  changed back to `${datadir}/terminfo`.
* `dpi-aware=auto`: fonts are now scaled using the monitor’s DPI only
  when **all** monitors have a scaling factor of one
  (https://codeberg.org/dnkl/foot/issues/714).

Fixed
-----

* Added workaround for GNOME bug where multiple button press events
  (for the same button) is sent to the CSDs without any release or
  leave events in between (https://codeberg.org/dnkl/foot/issues/709).
* Line-wise selection not taking soft line-wrapping into account
  (https://codeberg.org/dnkl/foot/issues/726).

Release 1.9.0

Added
-----

* Window title in the CSDs
  (https://codeberg.org/dnkl/foot/issues/638).
* `-Ddocs=disabled|enabled|auto` meson command line option.
* Support for `~`-expansion in the `include` directive
  (https://codeberg.org/dnkl/foot/issues/659).
* Unicode 13 characters U+1FB3C - U+1FB6F, U+1FB9A and U+1FB9B to list
  of box drawing characters rendered by foot itself (rather than using
  font glyphs) (https://codeberg.org/dnkl/foot/issues/474).
* `XM`+`xm` to terminfo.
* Mouse buttons 6/7 (mouse wheel left/right).
* `url.uri-characters` option to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/654).

Changed
-------

* Terminfo files can now co-exist with the foot terminfo files from
  ncurses. See `INSTALL.md` for more information
  (https://codeberg.org/dnkl/foot/issues/671).
* `bold-text-in-bright=palette-based` now only brightens colors from palette
* Raised grace period between closing the PTY and sending `SIGKILL` (when
  terminating the client application) from 4 to 60 seconds.
* When terminating the client application, foot now sends `SIGTERM` immediately
  after closing the PTY, instead of waiting 2 seconds.
* Foot now sends `SIGTERM`/`SIGKILL` to the client application’s process group,
  instead of just to the client application’s process.
* `kmous` terminfo capability from `\E[M` to `\E[<`.
* pt-or-px values (`letter-spacing`, etc) and the line thickness
  (`tweak.box-drawing-base-thickness`) in box drawing characters are
  now translated to pixel values using the monitor’s scaling factor
  when `dpi-aware=no`, or `dpi-aware=auto` and the scaling factor is
  larger than 1 (https://codeberg.org/dnkl/foot/issues/680).

Removed
-------

* `km`/`smm`/`rmm` from terminfo; foot prefixes Alt-key combinations
  with `ESC`, and not by setting the 8:th “meta” bit, regardless of
  `smm`/`rmm`. While this _can_ be disabled by, resetting private mode
  1036, the terminfo should reflect the **default** behavior
  (https://codeberg.org/dnkl/foot/issues/670).
* Keypad application mode keys from terminfo; enabling the keypad
  application mode is not enough to make foot emit these sequences -
  you also need to disable private mode 1035
  (https://codeberg.org/dnkl/foot/issues/670).

Fixed
-----

* Rendering into the right margin area with `tweak.overflowing-glyphs`
  enabled.
* PGO builds with clang (https://codeberg.org/dnkl/foot/issues/642).
* Crash in scrollback search mode when selection has been canceled due
  to terminal content updates
  (https://codeberg.org/dnkl/foot/issues/644).
* Foot process not terminating when the Wayland connection is broken
  (https://codeberg.org/dnkl/foot/issues/651).
* Output scale being zero on compositors that does not advertise a
  scaling factor.
* Slow-to-terminate client applications causing other footclient instances to
  freeze when closing a footclient window.
* Underlying cell content showing through in the left-most column of
  sixels.
* `cursor.blink` not working in GNOME
  (https://codeberg.org/dnkl/foot/issues/686).
* Blinking cursor stops blinking, or becoming invisible, when
  switching focus from, and then back to a terminal window on GNOME
  (https://codeberg.org/dnkl/foot/issues/686).

Release 1.8.2

Added
-----

* `locked-title=no|yes` to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/386).
* `tweak.overflowing-glyphs` option, which can be enabled to fix rendering
  issues with glyphs of any width that appear cut-off
  (https://codeberg.org/dnkl/foot/issues/592).

Changed
-------

* Non-empty lines are now considered to have a hard linebreak,
  _unless_ an actual word-wrap is inserted.
* Setting `DECSDM` now _disables_ sixel scrolling, while resetting it
  _enables_ scrolling (https://codeberg.org/dnkl/foot/issues/631).

Removed
-------

* The `tweak.allow-overflowing-double-width-glyphs` and
  `tweak.pua-double-width` options (which have been superseded by
  `tweak.overflowing-glyphs`).

Fixed
-----

* FD exhaustion when repeatedly entering/exiting URL mode with many
  URLs.
* Double free of URL while removing duplicated and/or overlapping URLs
  in URL mode (https://codeberg.org/dnkl/foot/issues/627).
* Crash when an unclosed OSC-8 URL ran into un-allocated scrollback
  rows.
* Some box-drawing characters were rendered incorrectly on big-endian
  architectures.
* Crash when resizing the window to the smallest possible size while
  scrollback search is active.
* Scrollback indicator being incorrectly rendered when window size is
  very small.
* Reduced memory usage in URL mode.
* Crash when the `E3` escape (`\E[3J`) was executed, and there was a
  selection, or sixel image, in the scrollback
  (https://codeberg.org/dnkl/foot/issues/633).

Release 1.8.1

Added
-----

* `--log-level=none` command-line option.
* `Tc`, `setrgbf` and `setrgbb` capabilities in `foot` and `foot-direct`
  terminfo entries. This should make 24-bit RGB colors work in tmux and
  neovim, without the need for config hacks or detection heuristics
  (https://codeberg.org/dnkl/foot/issues/615).

Changed
-------

* Grapheme cluster width is now limited to two cells by default. This
  may cause cursor synchronization issues with many applications. You
  can set `[tweak].grapheme-width-method=wcswidth` to revert to the
  behavior from foot-1.8.0.

Fixed
-----

* Grapheme cluster state being reset between codepoints.
* Regression: custom URL key bindings not working
  (https://codeberg.org/dnkl/foot/issues/614).

Release 1.8.0

Grapheme shaping
----------------

This release adds _experimental, opt-in_ support for grapheme cluster
segmentation and grapheme shaping.

(note: several of the examples below may not render correctly in your
browser, viewer or editor).

Grapheme cluster segmentation is the art of splitting up text into
grapheme clusters, where a cluster may consist of more than one
Unicode codepoint. For example, 🙂 is a single codepoint, while 👩🏽‍🚀
consists of 4 codepoints (_Woman_ + _Medium skin tone_ + _Zero width
joiner_ + _Rocket_). The goal is to _cluster_ codepoints belonging to
the same grapheme in the same cell in the terminal.

Previous versions of foot implemented a simple grapheme cluster
segmentation technique that **only** handled zero-width
codepoints. This allowed us to cluster combining characters, like q́
(_q_ + _COMBINING ACUTE ACCENT_).

Once we have a grapheme cluster, we need to _shape_ it.

Combining characters are simple: they are typically rendered as
multiple glyphs layered on top of each other. This is why previous
versions of foot got away with it without any actual text shaping
support.

Beyond that, support from the font library is needed. Foot now depends
on fcft-2.4, which added support for grapheme and text shaping. When
rendering a cell, we ask the font library: give us the glyph(s) for
this sequence of codepoints.

Fancy emoji sequences aside, using libutf8proc for grapheme cluster
segmentation means **improved correctness**.

For full support, the following is required:

* fcft compiled with HarfBuzz support
* foot compiled with libutf8proc support
* `tweak.grapheme-shaping=yes` in `foot.ini`

If `tweak.grapheme-shaping` has **not** been enabled, foot will
neither use libutf8proc to do grapheme cluster segmentation, nor will
it use fcft’s grapheme shaping capabilities to shape combining
characters.

This feature is _experimental_ mostly due to the “wcwidth” problem;
how many cells should foot allocate for a grapheme cluster? While the
answer may seem simple, the problem is that, whatever the answer is,
the client application **must** come up with the **same**
answer. Otherwise we get cursor synchronization issues.

In this release, foot simply adds together the `wcwidth()` of all
codepoints in the grapheme cluster. This is equivalent to running
`wcswidth()` on the entire cluster. **This is likely to change in the
future**.

Finally, note that grapheme shaping is not the same thing as text (or
text run) shaping. In this version, foot only shapes individual
graphemes, not entire text runs. That means e.g. ligatures are **not**
supported.

Added
-----

* Support for DECSET/DECRST 2026, as an alternative to the existing
  "synchronized updates" DCS sequences
  (https://codeberg.org/dnkl/foot/issues/459).
* `cursor.beam-thickness` option to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/464).
* `cursor.underline-thickness` option to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/524).
* Unicode 13 characters U+1FB70 - U+1FB8B to list of box drawing
  characters rendered by foot itself (rather than using font glyphs)
  (https://codeberg.org/dnkl/foot/issues/471).
* Dedicated `[bell]` section to config, supporting multiple actions
  and a new `command` action to run an arbitrary command.
  (https://codeberg.org/dnkl/foot/pulls/483)
* Dedicated `[url]` section to config.
* `[url].protocols` option to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/531).
* Support for setting the full 256 color palette in foot.ini
  (https://codeberg.org/dnkl/foot/issues/489)
* XDG activation support, will be used by `[bell].urgent` when
  available (falling back to coloring the window margins red when
  unavailable) (https://codeberg.org/dnkl/foot/issues/487).
* `ctrl`+`c` as a default key binding; to cancel search/url mode.
* `${window-title}` to `notify`.
* Support for including files in `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/555).
* `ENVIRONMENT` section in **foot**(1) and **footclient**(1) man pages
  (https://codeberg.org/dnkl/foot/issues/556).
* `tweak.pua-double-width` option to `foot.ini`, letting you force
  _Private Usage Area_ codepoints to be treated as double-width
  characters.
* OSC 9 desktop notifications (iTerm2 compatible).
* Support for LS2 and LS3 (locking shift) escape sequences
  (https://codeberg.org/dnkl/foot/issues/581).
* Support for overriding configuration options on the command line
  (https://codeberg.org/dnkl/foot/issues/554,
  https://codeberg.org/dnkl/foot/issues/600).
* `underline-offset` option to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/490).
* `csd.button-color` option to `foot.ini`.
* `-Dterminfo-install-location=disabled|<custom-path>` meson command
  line option (https://codeberg.org/dnkl/foot/issues/569).

Changed
-------

* [fcft](https://codeberg.org/dnkl/fcft): required version bumped from
  2.3.x to 2.4.x.
* `generate-alt-random-writes.py --sixel`: width and height of emitted
  sixels has been adjusted.
* _Concealed_ text (`\E[8m`) is now revealed when highlighted.
* The background color of highlighted text is now adjusted, when the
  foreground and background colors are the same, making the
  highlighted text legible
  (https://codeberg.org/dnkl/foot/issues/455).
* `cursor.style=bar` to `cursor.style=beam`. `bar` remains a
  recognized value, but will eventually be deprecated, and removed.
* Point values in `line-height`, `letter-spacing`,
  `horizontal-letter-offset` and `vertical-letter-offset` are now
  rounded, not truncated, when translated to pixel values.
* Foot’s exit code is now -26/230 when foot itself failed to launch
  (due to invalid command line options, client application/shell not
  found etc). Footclient’s exit code is -36/220 when it itself fails
  to launch (e.g. bad command line option) and -26/230 when the foot
  server failed to instantiate a new window
  (https://codeberg.org/dnkl/foot/issues/466).
* Background alpha no longer applied to palette or RGB colors that
  matches the background color.
* Improved performance on compositors that does not release shm
  buffers immediately, e.g. KWin
  (https://codeberg.org/dnkl/foot/issues/478).
* `ctrl + w` (_extend-to-word-boundary_) can now be used across lines
  (https://codeberg.org/dnkl/foot/issues/421).
* Ignore auto-detected URLs that overlap with OSC-8 URLs.
* Default value for the `notify` option to use `-a ${app-id} -i
  ${app-id} ...` instead of `-a foot -i foot ...`.
* `scrollback-*`+`pipe-scrollback` key bindings are now passed through
  to the client application when the alt screen is active
  (https://codeberg.org/dnkl/foot/issues/573).
* Reverse video (`\E[?5h`) now only swaps the default foreground and
  background colors. Cells with explicit foreground and/or background
  colors remain unchanged.
* Tabs (`\t`) are now preserved when the window is resized, and when
  copying text (https://codeberg.org/dnkl/foot/issues/508).
* Writing a sixel on top of another sixel no longer erases the first
  sixel, but the two are instead blended
  (https://codeberg.org/dnkl/foot/issues/562).
* Running foot without a configuration file is no longer an error; it
  has been demoted to a warning, and is no longer presented as a
  notification in the terminal window, but only logged on stderr.

Deprecated
----------

* `bell` option in `foot.ini`; set actions in the `[bell]` section
  instead.
* `url-launch` option in `foot.ini`; use `launch` in the `[url]`
  section instead.
* `jump-label-letters` option in `foot.ini`; use `label-letters` in
  the `[url]` section instead.
* `osc8-underline` option in `foot.ini`; use `osc8-underline` in the
  `[url]` section instead.

Removed
-------

* Buffer damage quirk for Plasma/KWin.

Fixed
-----

* `generate-alt-random-writes.py --sixel` sometimes crashing,
  resulting in PGO build failures.
* Wrong colors in the 256-color cube
  (https://codeberg.org/dnkl/foot/issues/479).
* Memory leak triggered by “opening” an OSC-8 URI and then resetting
  the terminal without closing the URI
  (https://codeberg.org/dnkl/foot/issues/495).
* Assertion when emitting a sixel occupying the entire scrollback
  history (https://codeberg.org/dnkl/foot/issues/494).
* Font underlines being positioned below the cell (and thus being
  invisible) for certain combinations of fonts and font sizes
  (https://codeberg.org/dnkl/foot/issues/503).
* Sixels with transparent bottom border being resized below the size
  specified in _”Set Raster Attributes”_.
* Fonts sometimes not being reloaded with the correct scaling factor
  when `dpi-aware=no`, or `dpi-aware=auto` with monitor(s) with a
  scaling factor > 1 (https://codeberg.org/dnkl/foot/issues/509).
* Crash caused by certain CSI sequences with very large parameter
  values (https://codeberg.org/dnkl/foot/issues/522).
* Rare occurrences where the window did not close when the shell
  exited. Only seen on FreeBSD
  (https://codeberg.org/dnkl/foot/issues/534)
* Foot process(es) sometimes remaining, using 100% CPU, when closing
  multiple foot windows at the same time
  (https://codeberg.org/dnkl/foot/issues/542).
* Regression where `<mod>+shift+tab` always produced `\E[Z` instead of
  the correct `\E[27;<mod>;9~` sequence
  (https://codeberg.org/dnkl/foot/issues/547).
* Crash when a line wrapping OSC-8 URI crossed the scrollback wrap
  around (https://codeberg.org/dnkl/foot/issues/552).
* Selection incorrectly wrapping rows ending with an explicit newline
  (https://codeberg.org/dnkl/foot/issues/565).
* Off-by-one error in markup of auto-detected URLs when the URL ends
  in the right-most column.
* Multi-column characters being cut in half when resizing the
  alternate screen.
* Restore `SIGHUP` in spawned processes.
* Text reflow performance (https://codeberg.org/dnkl/foot/issues/504).
* IL+DL (`CSI Ps L` + `CSI Ps M`) now moves the cursor to column 0.
* SS2 and SS3 (single shift) escape sequences behaving like locking
  shifts (https://codeberg.org/dnkl/foot/issues/580).
* `TEXT`+`STRING`+`UTF8_STRING` mime types not being recognized in
  clipboard offers (https://codeberg.org/dnkl/foot/issues/583).
* Memory leak caused by custom box drawing glyphs not being completely
  freed when destroying a foot window instance
  (https://codeberg.org/dnkl/foot/issues/586).
* Crash in scrollback search when current XKB layout is missing
  _compose_ definitions.
* Window title not being updated while window is hidden
  (https://codeberg.org/dnkl/foot/issues/591).
* Crash on badly formatted URIs in e.g. OSC-8 URLs.
* Window being incorrectly resized on CSD/SSD run-time changes.

Release 1.7.2

Added
-----

* URxvt OSC-11 extension to set background alpha
  (https://codeberg.org/dnkl/foot/issues/436).
* OSC 17/117/19/119 - change/reset selection background/foreground
  color.
* `box-drawings-uses-font-glyphs=yes|no` option to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/430).

Changed
-------

* Underline cursor is now rendered below text underline
  (https://codeberg.org/dnkl/foot/issues/415).
* Foot now tries much harder to keep URL jump labels inside the window
  geometry (https://codeberg.org/dnkl/foot/issues/443).
* `bold-text-in-bright` may now be set to `palette-based`, in which
  case it will use the corresponding bright palette color when the
  color to brighten matches one of the base 8 colors, instead of
  increasing the luminance
  (https://codeberg.org/dnkl/foot/issues/449).

Fixed
-----

* Reverted _"Consumed modifiers are no longer sent to the client
  application"_ (https://codeberg.org/dnkl/foot/issues/425).
* Crash caused by a double free originating in `XTSMGRAPHICS` - set
  number of color registers
  (https://codeberg.org/dnkl/foot/issues/427).
* Wrong action referenced in error message for key binding collisions
  (https://codeberg.org/dnkl/foot/issues/432).
* OSC 4/104 out-of-bounds accesses to the color table. This was the
  reason pywal turned foot windows transparent
  (https://codeberg.org/dnkl/foot/issues/434).
* PTY not being drained when the client application terminates.
* `auto_left_margin` not being limited to `cub1`
  (https://codeberg.org/dnkl/foot/issues/441).

Release 1.7.1

Changed
-------

* Update PGO build instructions in `INSTALL.md`
  (https://codeberg.org/dnkl/foot/issues/418).
* In scrollback search mode, empty cells can now be matched by spaces.

Fixed
-----

* Logic that repairs invalid key bindings ended up breaking valid key
  bindings instead (https://codeberg.org/dnkl/foot/issues/407).
* Custom `line-height` settings now scale when increasing or
  decreasing the font size at run-time.
* Newlines sometimes incorrectly inserted into copied text
  (https://codeberg.org/dnkl/foot/issues/410).
* Crash when compositor send `text-input-v3::enter` events without
  first having sent a `keyboard::enter` event
  (https://codeberg.org/dnkl/foot/issues/411).
* Deadlock when rendering sixel images.
* URL labels, scrollback search box or scrollback position indicator
  sometimes not showing up, caused by invalidly sized surface buffers
  when output scaling was enabled
  (https://codeberg.org/dnkl/foot/issues/409).
* Empty sixels resulted in non-empty images.

Release 1.7.0

Added
-----

* The `pad` option now accepts an optional third argument, `center`
  (e.g. `pad=5x5 center`), causing the grid to be centered in the
  window, with equal amount of padding of the left/right and
  top/bottom side (https://codeberg.org/dnkl/foot/issues/273).
* `line-height`, `letter-spacing`, `horizontal-letter-offset` and
  `vertical-letter-offset` to `foot.ini`. These options let you tweak
  cell size and glyph positioning
  (https://codeberg.org/dnkl/foot/issues/244).
* Key/mouse binding `select-extend-character-wise`, which forces the
  selection mode to 'character-wise' when extending a selection.
* `DECSET` `47`, `1047` and `1048`.
* URL detection and OSC-8 support. URLs are highlighted and activated
  using the keyboard (**no** mouse support). See **foot**(1)::URLs, or
  [README.md](README.md#urls) for details
  (https://codeberg.org/dnkl/foot/issues/14).
* `-d,--log-level={info|warning|error}` to both `foot` and
  `footclient` (https://codeberg.org/dnkl/foot/issues/337).
* `-D,--working-directory=DIR` to both `foot` and `footclient`
  (https://codeberg.org/dnkl/foot/issues/347)
* `DECSET 80` - sixel scrolling
  (https://codeberg.org/dnkl/foot/issues/361).
* `DECSET 1070` - sixel private color palette
  (https://codeberg.org/dnkl/foot/issues/362).
* `DECSET 8452` - position cursor to the right of sixels
  (https://codeberg.org/dnkl/foot/issues/363).
* Man page **foot-ctlseqs**(7), documenting all supported escape
  sequences (https://codeberg.org/dnkl/foot/issues/235).
* Support for transparent sixels (DCS parameter `P2=1`)
  (https://codeberg.org/dnkl/foot/issues/391).
* `-N,--no-wait` to `footclient`
  (https://codeberg.org/dnkl/foot/issues/395).
* Completions for Bash shell
  (https://codeberg.org/dnkl/foot/issues/10).

Changed
-------

* The fcft and tllist library subprojects are now handled via Meson
  [wrap files](https://mesonbuild.com/Wrap-dependency-system-manual.html)
  instead of needing to be manually cloned.
* Box drawing characters are now rendered by foot, instead of using
  font glyphs (https://codeberg.org/dnkl/foot/issues/198)
* Double- or triple clicking then dragging now extends the selection
  word- or line-wise (https://codeberg.org/dnkl/foot/issues/267).
* The line thickness of box drawing characters now depend on the font
  size (https://codeberg.org/dnkl/foot/issues/281).
* Extending a word/line-wise selection now uses the original selection
  mode instead of switching to character-wise.
* While doing an interactive resize of a foot window, foot now
  requires 100ms of idle time (where the window size does not change)
  before sending the new dimensions to the client application. The
  timing can be tweaked, or completely disabled, by setting
  `resize-delay-ms` (https://codeberg.org/dnkl/foot/issues/301).
* `CSI 13 ; 2 t` now reports (0,0).
* Key binding matching logic; key combinations like `Control+Shift+C`
  **must** now be written as either `Control+C` or `Control+Shift+c`,
  the latter being the preferred
  variant. (https://codeberg.org/dnkl/foot/issues/376)
* Consumed modifiers are no longer sent to the client application
  (https://codeberg.org/dnkl/foot/issues/376).
* The minimum version requirement for the libxkbcommon dependency is
  now 1.0.0.
* Empty pixel rows at the bottom of a sixel is now trimmed.
* Sixels with DCS parameter `P2=0|2` now use the _current_ ANSI
  background color for empty pixels instead of the default background
  color (https://codeberg.org/dnkl/foot/issues/391).
* Sixel decoding optimized; up to 100% faster in some cases.
* Reported sixel “max geometry” from current window size, to the
  configured maximum size (defaulting to 10000x10000).

Removed
-------

* The `-g,--geometry` command-line option (which had been deprecated
  and superseded by `-w,--window-size-pixels` since 1.5.0).

Fixed
-----

* Some mouse bindings (_primary paste_, for example) did not require
  `shift` to be pressed while used in a mouse grabbing
  application. This meant the mouse event was never seen by the
  application.
* Terminals spawned with `ctrl`+`shift`+`n` not terminating when
  exiting shell (https://codeberg.org/dnkl/foot/issues/366).

Release 1.6.4

Added
-----

* `selection-target=none|primary|clipboard|both` to `foot.ini`. It can
  be used to configure which clipboard(s) selected text should be
  copied to. The default is `primary`, which corresponds to the
  behavior in older foot releases
  (https://codeberg.org/dnkl/foot/issues/288).

Changed
-------

* The IME state no longer stays stuck in the terminal if the IME goes
  away during preedit.
* `-Dterminfo` changed from a `boolean` to a `feature` option.
* Use standard signals instead of a signalfd to handle
  `SIGCHLD`. Fixes an issue on FreeBSD where foot did not detect when
  the client application had terminated.

Fixed
-----

* `BS`, `HT` and `DEL` from being stripped in bracketed paste mode.

Release 1.6.3

Added
-----

* Completions for fish shell
  (https://codeberg.org/dnkl/foot/issues/11)
* FreeBSD support (https://codeberg.org/dnkl/foot/issues/238).
* IME popup location support: foot now sends the location of the cursor
  so any popup can be displayed near the text that is being typed.

Changed
-------

* Trailing comments in `foot.ini` must now be preceded by a space or tab
  (https://codeberg.org/dnkl/foot/issues/270)
* The scrollback search box no longer accepts non-printable characters.
* Non-formatting C0 control characters, `BS`, `HT` and `DEL` are now
  stripped from pasted text.

Fixed
-----

* Exit when the client application terminates, not when the TTY file
  descriptor is closed.
* Crash on compositors not implementing the _text input_ interface
  (https://codeberg.org/dnkl/foot/issues/259).
* Erased, overflowing glyphs (when
  `tweak.allow-overflowing-double-width-glyphs=yes` - the default) not
  properly erasing the cell overflowed **into**.
* `word-delimiters` option ignores `#` and subsequent characters
  (https://codeberg.org/dnkl/foot/issues/270)
* Combining characters not being rendered when composed with colored
  bitmap glyphs (i.e. colored emojis).
* Pasting URIs from the clipboard when the source has not
  newline-terminated the last URI
  (https://codeberg.org/dnkl/foot/issues/291).
* Sixel “current geometry” query response not being bounded by the
  current window dimensions (fixes `lsix` output)
* Crash on keyboard input when repeat rate was zero (i.e. no repeat).
* Wrong button encoding of mouse buttons 6 and 7 in mouse events.
* Scrollback search not matching composed characters.
* High CPU usage when holding down e.g. arrow keys while in scrollback
  search mode.
* Rendering of composed characters in the scrollback search box.
* IME pre-edit cursor when positioned at the end of the pre-edit
  string.
* Scrollback search not matching multi-column characters.

Release 1.6.2

Fixed
-----

Release 1.6.1

Added
-----

* `--seed` to `generate-alt-random.py`, enabling deterministic PGO
  builds.

Changed
-------

* Use `-std=c11` instead of `-std=c18`.
* Added `-Wno-profile-instr-unprofiled` to Clang cflags in PGO builds
  ([INSTALL.md](https://codeberg.org/dnkl/foot/src/branch/releases/1.6/INSTALL.md#user-content-performance-optimized-pgo))

Fixed
-----

* Missing dependencies in meson, causing heavily parallelized builds
  to fail.
* Background color when alpha < 1.0 being wrong
  (https://codeberg.org/dnkl/foot/issues/249).
* `generate-alt-random.py` failing in containers.

Release 1.6.0

For packagers
-------------

Starting with this release, foot can be PGO:d (compiled using profile
guided optimizations) **without** a running Wayland session. This
means foot can be PGO:d in e.g. sandboxed build scripts. See
[INSTALL.md](INSTALL.md#user-content-performance-optimized-pgo).

Added
-----

* IME support. This is compile-time optional, see
  [INSTALL.md](INSTALL.md#user-content-options)
  (https://codeberg.org/dnkl/foot/issues/134).
* `DECSET` escape to enable/disable IME: `CSI ? 737769 h` enables IME
  and `CSI ? 737769 l` disables it. This can be used to
  e.g. enable/disable IME when entering/leaving insert mode in vim.
* `dpi-aware` option to `foot.ini`. The default, `auto`, sizes fonts
  using the monitor’s DPI when output scaling has been
  **disabled**. If output scaling has been **enabled**, fonts are
  sized using the scaling factor. DPI-only font sizing can be forced
  by setting `dpi-aware=yes`. Setting `dpi-aware=no` forces font
  sizing to be based on the scaling factor.
  (https://codeberg.org/dnkl/foot/issues/206).
* Implement reverse auto-wrap (_auto\_left\_margin_, _bw_, in
  terminfo). This mode can be enabled/disabled with `CSI ? 45 h` and
  `CSI ? 45 l`. It is **enabled** by default
  (https://codeberg.org/dnkl/foot/issues/150).
* `bell` option to `foot.ini`. Can be set to `set-urgency` to make
  foot render the margins in red when receiving `BEL` while **not**
  having keyboard focus. Applications can dynamically enable/disable
  this with the `CSI ? 1042 h` and `CSI ? 1042 l` escape
  sequences. Note that Wayland does **not** implement an _urgency_
  hint like X11, but that there is a
  [proposal](https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/9)
  to add support for this. The value `set-urgency` was chosen for
  forward-compatibility, in the hopes that this proposal eventualizes
  (https://codeberg.org/dnkl/foot/issues/157).
* `bell` option can also be set to `notify`, in which case a desktop
  notification is emitted when foot receives `BEL` in an unfocused
  window.
* `word-delimiters` option to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/156).
* `csd.preferred` can now be set to `none` to disable window
  decorations. Note that some compositors will render SSDs despite
  this option being used (https://codeberg.org/dnkl/foot/issues/163).
* Terminal content is now auto-scrolled when moving the mouse above or
  below the window while selecting
  (https://codeberg.org/dnkl/foot/issues/149).
* `font-bold`, `font-italic` `font-bold-italic` options to
  `foot.ini`. These options allow custom bold/italic fonts. They are
  unset by default, meaning the bold/italic version of the regular
  font is used (https://codeberg.org/dnkl/foot/issues/169).
* Drag & drop support; text, files and URLs can now be dropped in a
  foot terminal window (https://codeberg.org/dnkl/foot/issues/175).
* `clipboard-paste` and `primary-paste` scrollback search bindings. By
  default, they are bound to `ctrl+v ctrl+y` and `shift+insert`
  respectively, and lets you paste from the clipboard or primary
  selection into the search buffer.
* Support for `pipe-*` actions in mouse bindings. It was previously
  not possible to add a command to these actions when used in mouse
  bindings, making them useless
  (https://codeberg.org/dnkl/foot/issues/183).
* `bold-text-in-bright` option to `foot.ini`. When enabled, bold text
  is rendered in a brighter color
  (https://codeberg.org/dnkl/foot/issues/199).
* `-w,--window-size-pixels` and `-W,--window-size-chars` command line
  options to `footclient` (https://codeberg.org/dnkl/foot/issues/189).
* Short command line options for `--title`, `--maximized`,
  `--fullscreen`, `--login-shell`, `--hold` and `--check-config`.
* `DECSET` escape to modify the `escape` key to send `\E[27;1;27~`
  instead of `\E`: `CSI ? 27127 h` enables the new behavior, `CSI ?
  27127 l` disables it (the default).
* OSC 777;notify: desktop notifications. Use in combination with the
  new `notify` option in `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/224).
* Status line terminfo capabilities `hs`, `tsl`, `fsl` and `dsl`. This
  enables e.g. vim to set the window title
  (https://codeberg.org/dnkl/foot/issues/242).

Changed
-------

* Blinking text now uses the foreground color, but dimmed down in its
  off state, instead of the background color.
* Sixel default maximum size is now 10000x10000 instead of the current
  window size.
* Graphical glitches/flashes when resizing the window while running a
  fullscreen application, i.e. the 'alt' screen
  (https://codeberg.org/dnkl/foot/issues/221).
* Cursor will now blink if **either** `CSI ? 12 h` or `CSI Ps SP q`
  has been used to enable blinking. **cursor.blink** in `foot.ini`
  controls the default state of `CSI Ps SP q`
  (https://codeberg.org/dnkl/foot/issues/218).
* The sub-parameter versions of the SGR RGB color escapes (e.g
  `\E[38:2...m`) can now be used _without_ the color space ID
  parameter.
* SGR 21 no longer disables **bold**. According to ECMA-48, SGR 21 is
  _”double underline_”. Foot does not (yet) implement that, but that’s
  no reason to implement a non-standard behavior.
* `DECRQM` now returns actual state of the requested mode, instead of
  always returning `2`.

Removed
-------

* Support for loading configuration from `$XDG_CONFIG_HOME/footrc`.
* `scrollback` option from `foot.ini`.
* `geometry` from `foot.ini`.
* Key binding action `scrollback-up` and `scrollback-down`.

Fixed
-----

* Error when re-assigning a default key binding
  (https://codeberg.org/dnkl/foot/issues/233).
* `\E[s`+`\E[u` (save/restore cursor) now saves and restores
  attributes and charset configuration, just like `\E7`+`\E8`.
* Report mouse motion events to the client application also while
  dragging the cursor outside the grid.
* Parsing of the sub-parameter versions of indexed SGR color escapes
  (e.g. `\E[38:5...m`)
* Frames occasionally being rendered while application synchronized
  updates is in effect.
* Handling of failures to parse the font specification string.
* Extra private/intermediate characters in escape sequences not being
  ignored.

Release 1.5.4

Changed
-------

* Num Lock by default overrides the keypad mode. See
  **foot.ini**(5)::KEYPAD, or
  [README.md](README.md#user-content-keypad) for details
  (https://codeberg.org/dnkl/foot/issues/194).
* Single-width characters with double-width glyphs are now allowed to
  overflow into neighboring cells by default. Set
  **tweak.allow-overflowing-double-width-glyphs** to ‘no’ to disable
  this.

Fixed
-----

* Resize very slow when window is hidden
  (https://codeberg.org/dnkl/foot/issues/190).
* Key mappings for key combinations with `shift`+`tab`
  (https://codeberg.org/dnkl/foot/issues/210).
* Key mappings for key combinations with `alt`+`return`.
* `footclient` `-m` (`--maximized`) flag being ignored.
* Crash with explicitly sized sixels with a height less than 6 pixels.
* Key mappings for `esc` with modifiers.

Release 1.5.3

Fixed
-----

* Crash when libxkbcommon cannot find a suitable libX11 _compose_
  file. Note that foot will run, but without support for dead keys.
  (https://codeberg.org/dnkl/foot/issues/170).
* Restored window size when window is un-tiled.
* XCursor shape in CSD corners when window is tiled.
* Error handling when processing keyboard input (maybe
  https://codeberg.org/dnkl/foot/issues/171).
* Compilation error _"overflow in conversion from long 'unsigned int'
  to 'int' changes value... "_ seen on platforms where the `request`
  argument in `ioctl(3)` is an `int` (for example: linux/ppc64).
* Crash when using the mouse in alternate scroll mode in an unfocused
  window (https://codeberg.org/dnkl/foot/issues/179).
* Character dropped from selection when "right-click-hold"-extending a
  selection (https://codeberg.org/dnkl/foot/issues/180).

Release 1.5.2

Fixed
-----

* Regression: middle clicking double pastes in e.g. vim
  (https://codeberg.org/dnkl/foot/issues/168)

Release 1.5.1

Changed
-------

* Default value of the **scrollback.multiplier** option in `foot.ini`
  from `1.0` to `3.0`.
* `shift`+`insert` now pastes from the primary selection by
  default. This is in addition to middle-clicking with the mouse.

Fixed
-----

* Mouse bindings now match even if the actual click count is larger
  than specified in the binding. This allows you to, for example,
  quickly press the middle-button to paste multiple times
  (https://codeberg.org/dnkl/foot/issues/146).
* Color flashes when changing the color palette with OSC 4,10,11
  (https://codeberg.org/dnkl/foot/issues/141).
* Scrollback position is now retained when resizing the window
  (https://codeberg.org/dnkl/foot/issues/142).
* Trackpad scrolling speed to better match the mouse scrolling speed,
  and to be consistent with other (Wayland) terminal emulators. Note
  that it is (much) slower compared to previous foot versions. Use the
  **scrollback.multiplier** option in `foot.ini` if you find the new
  speed too slow (https://codeberg.org/dnkl/foot/issues/144).
* Crash when `foot.ini` contains an invalid section name
  (https://codeberg.org/dnkl/foot/issues/159).
* Background opacity when in _reverse video_ mode.
* Crash when writing a sixel image that extends outside the terminal's
  right margin (https://codeberg.org/dnkl/foot/issues/151).
* Sixel image at non-zero column positions getting sheared at
  seemingly random occasions
  (https://codeberg.org/dnkl/foot/issues/151).
* Crash after either resizing a window or changing the font size if
  there were sixels present in the scrollback while doing so.
* _Send Device Attributes_ to only send a response if `Ps == 0`.
* Paste from primary when clipboard is empty.

Release 1.5.0

Deprecated
----------

* `$XDG_CONFIG_HOME/footrc`/`~/.config/footrc`. Use
  `$XDG_CONFIG_HOME/foot/foot.ini`/`~/.config/foot/foot.ini` instead.
* **scrollback** option in `foot.ini`. Use **scrollback.lines**
  instead.
* **scrollback-up** key binding. Use **scrollback-up-page** instead.
* **scrollback-down** key binding. Use **scrollback-down-page**
  instead.

Added
-----

* Scrollback position indicator. This feature is optional and
  controlled by the **scrollback.indicator-position** and
  **scrollback.indicator-format** options in `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/42).
* Key bindings in _scrollback search_ mode are now configurable.
* `--check-config` command line option.
* **pipe-selected** key binding. Works like **pipe-visible** and
  **pipe-scrollback**, but only pipes the currently selected text, if
  any (https://codeberg.org/dnkl/foot/issues/51).
* **mouse.hide-when-typing** option to `foot.ini`.
* **scrollback.multiplier** option to `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/54).
* **colors.selection-foreground** and **colors.selection-background**
  options to `foot.ini`.
* **tweak.render-timer** option to `foot.ini`.
* Modifier support in mouse bindings
  (https://codeberg.org/dnkl/foot/issues/77).
* Click count support in mouse bindings, i.e double- and triple-click
  (https://codeberg.org/dnkl/foot/issues/78).
* All mouse actions (begin selection, select word, select row etc) are
  now configurable, via the new **select-begin**,
  **select-begin-block**, **select-extend**, **select-word**,
  **select-word-whitespace** and **select-row** options in the
  **mouse-bindings** section in `foot.ini`
  (https://codeberg.org/dnkl/foot/issues/79).
* Implement XTSAVE/XTRESTORE escape sequences, `CSI ? Ps s` and `CSI ?
  Ps r` (https://codeberg.org/dnkl/foot/issues/91).
* `$COLORTERM` is now set to `truecolor` at startup, to indicate
  support for 24-bit RGB colors.
* Experimental support for rendering double-width glyphs with a
  character width of 1. Must be explicitly enabled with
  `tweak.allow-overflowing-double-width-glyphs`
  (https://codeberg.org/dnkl/foot/issues/116).
* **initial-window-size-pixels** options to `foot.ini` and
  `-w,--window-size-pixels` command line option to `foot`. This option
  replaces the now deprecated **geometry** and `-g,--geometry`
  options.
* **initial-window-size-chars** option to `foot.ini` and
  `-W,--window-size-chars` command line option to `foot`. This option
  configures the initial window size in **characters**, and is an
  alternative to **initial-window-size-pixels**.
* **scrollback-up-half-page** and **scrollback-down-half-page** key
  bindings. They scroll up/down half of a page in the scrollback
  (https://codeberg.org/dnkl/foot/issues/128).
* **scrollback-up-line** and **scrollback-down-line** key
  bindings. They scroll up/down a single line in the scrollback.
* **mouse.alternate-scroll-mode** option to `foot.ini`. This option
  controls the initial state of the _Alternate Scroll Mode_, and
  defaults to `yes`. When enabled, mouse scroll events are translated
  to up/down key events in the alternate screen, letting you scroll in
  e.g. `less` and other applications without enabling native mouse
  support in them (https://codeberg.org/dnkl/foot/issues/135).

Changed
-------

* Renamed man page for `foot.ini` from **foot**(5) to **foot.ini**(5).
* Configuration errors are no longer fatal; foot will start and print
  an error inside the terminal (and of course still log errors on
  stderr).
* Default `--server` socket path to use `$WAYLAND_DISPLAY` instead of
  `$XDG_SESSION_ID` (https://codeberg.org/dnkl/foot/issues/55).
* Trailing empty cells are no longer highlighted in mouse selections.
* Foot now searches for its configuration in
  `$XDG_DATA_DIRS/foot/foot.ini`, if no configuration is found in
  `$XDG_CONFIG_HOME/foot/foot.ini` or in `$XDG_CONFIG_HOME/footrc`.
* Minimum window size changed from four rows and 20 columns, to 1 row
  and 2 columns.
* **scrollback-up/down** renamed to **scrollback-up/down-page**.
* fcft >= 2.3.0 is now required.

Fixed
-----

* Command lines for **pipe-visible** and **pipe-scrollback** are now
  tokenized (i.e. syntax checked) when the configuration is loaded,
  instead of every time the key binding is executed.
* Incorrect multi-column character spacer insertion when reflowing
  text.
* Compilation errors in 32-bit builds.
* Mouse cursor style in top and left margins.
* Selection is now **updated** when the cursor moves outside the grid
  (https://codeberg.org/dnkl/foot/issues/70).
* Viewport sometimes not moving when doing a scrollback search.
* Crash when canceling a scrollback search and the window had been
  resized while searching.
* Selection start point not moving when the selection changes
  direction.
* OSC 10/11/104/110/111 (modify colors) did not update existing screen
  content (https://codeberg.org/dnkl/foot/issues/94).
* Extra newlines when copying empty cells
  (https://codeberg.org/dnkl/foot/issues/97).
* Mouse events from being sent to client application when a mouse
  binding has consumed it.
* Input events from getting mixed with paste data
  (https://codeberg.org/dnkl/foot/issues/101).
* Missing DPI values for “some” monitors on Gnome
  (https://codeberg.org/dnkl/foot/issues/118).
* Handling of multi-column composed characters while reflowing.
* Escape sequences sent for key combinations with `Return`, that did
  **not** include `Alt`.
* Clipboard (or primary selection) is now cleared when receiving an
  OSC-52 command with an invalid base64 encoded payload.
* Cursor position being set outside the grid when reflowing text.
* CSD buttons to be hidden when window size becomes so small that they
  no longer fit.

Release 1.4.4

Changed
-------

* Mouse cursor is now always a `left_ptr` when inside the margins, to
  indicate it is not possible to start a selection.

Fixed
-----

* Crash when starting a selection inside the margins.
* Improved font size consistency across multiple monitors with
  different DPI (https://codeberg.org/dnkl/foot/issues/47).
* Handle trailing comments in `footrc`
