1.4.0 – Launch Notes

Ghostty 1.4.0 is a significant launch that features massive efficiency and
reminiscence enhancements, a 100% full Kitty graphics implementation together with
animation and relative placements (the primary non-Kitty terminal to take action),
SSH integration enhancements, and lots of extra enhancements and fixes
throughout all platforms.

This launch options 7 months of labor with adjustments from
172 contributors over 2,889 commits. Thank you to all of the contributors,
maintainers, group moderators, translators, packagers, and customers
who every helped make this launch doable.

These launch notes are painstakingly and lovingly hand-crafted
by human Ghostty maintainers, together with the total changelog. They take
a mixed 16+ hours to put in writing, so please take pleasure in. 🥰

• GHSA-4hwh-wx3w-3fqg.
  Paste safety did not deal with carriage returns as line endings, so a
  paste may run a command with out affirmation in applications that do not
  use bracketed paste. This requires consumer interplay (copy-paste) to
  set off.
• GHSA-mhff-mv4q-fp63.
  Malicious Kitty graphics instructions may crash or cling Ghostty, power
  big allocations, or in restricted circumstances learn or delete information outdoors the
  allowed momentary directories. This solely requires displaying malicious
  output.
• GHSA-hcr9-7hcr-mjm8.
  Malicious terminal output may crash Ghostty, closing each window,
  by way of tmux management mode. tmux would not must be put in. This impacts
  Ghostty 1.3.0 and 1.3.1.
• GHSA-hp9c-qp4q-cpw3.
  The similar affect as above, by way of a tmux management mode structure with a
  zero-sized or outsized pane. This impacts Ghostty 1.3.0 and 1.3.1.
• GHSA-w9q4-5jvv-mcv4.
  Clearing the display into scrollback may corrupt reminiscence if it deleted
  the scrollback web page holding a styled or hyperlinked cursor. This solely
  requires displaying malicious output, however solely with a small
  scrollback-limit comparable to 0. The default is not recognized to be affected.
• GHSA-2r63-vmw6-3m3c.
  A crafted listing title may make the zsh shell integration ship
  arbitrary escape sequences, comparable to silently changing the clipboard by way of
  OSC 52. bash was affected in a extra restricted method. This solely requires
  cd-ing right into a listing from untrusted content material, comparable to a cloned
  repository.
• macOS: GHSA-cw69-wm67-5pv8.
  Cmd-clicking a crafted OSC 8 hyperlink may open unsafe native information or
  customized URL schemes, resulting in arbitrary command execution. Ghostty now
  blocks unsafe targets and confirms customized URL schemes. This requires
  consumer interplay (cmd-click) to set off.
• macOS: GHSA-mfw9-xcr3-7gfp.
  The similar difficulty as above for hyperlinks detected by the hyperlink configuration,
  together with the default URL matcher. This requires consumer interplay
  (cmd-click) to set off.
• macOS: GHSA-v8cw-fg4j-jcc4.
  Drag-and-drop textual content skipped paste safety, with the identical affect as
  above. This requires consumer interplay (drag-and-drop) to set off.
• macOS: GHSA-mxqx-236q-wrv7.
  Opening a file whose title accommodates management characters may run a
  completely different command than the one proven within the affirmation dialog. This
  requires a crafted file in your system and confirming the dialog.

Note: I requested CVEs for the above advisories weeks in the past, however GitHub
hasn’t assigned them but. If/once they’re assigned, I’ll replace the
above with correct CVE numbers.

Ghostty 1.4 helps macOS 27 (Golden Gate). Most of the work was
compatibility fixes:

• Tabs within the titlebar (macos-titlebar-style = tabs) lay out appropriately
  once more.
• The native tab bar now not attracts as a stable grey bar on high of your
  theme. It now lets the brand new glass model mix along with your terminal
  background.
• macos-titlebar-style = hidden now not covers the highest traces of the
  terminal when Reduce Transparency is on.
• The app icon now not has a skinny border.
• The Shortcuts “New Window” motion now not opens two home windows when
  Ghostty is working with none home windows.

Ghostty 1.4 stays absolutely suitable with prior macOS variations again to
and together with macOS 13 (Ventura). See the
system requirements for extra particulars.

Ghostty 1.3.1 works on macOS 27, nevertheless it has among the visible points
listed above, comparable to the grey tab bar.

Ghostty now helps Kitty graphics
animation
and relative placements.
These have been the final main options of the Kitty graphics protocol that
Ghostty did not help.

Programs that show animated photos with the Kitty protocol, comparable to an
animated GIF proven with kitten icat, now animate in Ghostty as a substitute of
displaying a single nonetheless body. Frame transmission, composition, and playback
management are all supported, and animations pause whereas the terminal is not
seen. Relative placements let a program place one picture relative to
one other picture’s placement, so the kid picture strikes together with its dad or mum.

We additionally did a full conformance move in opposition to the specification and Kitty
itself, fixing dozens of behavioral variations. For instance, photos now
scroll with textual content inside scroll areas (#4323 ), retransmitting a picture
ID replaces the previous picture (#6711 ), and invalid picture information now will get an
error response as a substitute of silence, which may go away shoppers hanging. The
full checklist is within the terminal capabilities part.

Kitty graphics are sooner, too. Image payloads are actually parsed in bulk
with SIMD as a substitute of 1 byte at a time, making massive picture transfers
about 16x sooner to parse in our benchmarks (64 MiB of picture information,
x86_64 Linux), and drawing photos prices a lot much less per body.

Our Kitty graphics implementation now covers 100% of the revealed
specification, making Ghostty (and libghostty) the primary terminal
to do that outdoors of Kitty itself.

Ghostty now transparently compresses scrollback that is not seen,
decreasing the bodily reminiscence these pages use by 70% to 90% for typical
text-heavy historical past. Compression solely runs whereas the terminal is idle and
pages are decompressed on demand whenever you scroll again or search, so it
has no measurable affect on I/O throughput.

Thanks to compression, the default scrollback restrict has been raised from
10 MB to 50 MB per terminal. On platforms that help compression, a
full scrollback nonetheless usually makes use of much less bodily reminiscence than the previous
10 MB restrict did.

Compression lowers resident (bodily) reminiscence, not digital reminiscence, so
take a look at resident reminiscence when measuring it. It is presently out there on
macOS and 64-bit Linux.

Beyond scrollback, reminiscence utilization is decrease in lots of locations:

• A brand new, empty terminal now makes use of about 16 KiB of terminal web page reminiscence
  on macOS, down from 128 KiB in Ghostty 1.3.1.
• On macOS and Linux, reminiscence freed by clearing or trimming scrollback is
  now returned to the OS as a substitute of being held till the terminal closes.
• Hidden tabs launch their GPU sources. On macOS, with one seen tab
  and 20 hidden tabs, GPU reminiscence dropped from about 385 MiB to 18 MiB.
  Rebuilding them when a tab turns into seen once more takes below a
  millisecond.

There are efficiency enhancements throughout the board in Ghostty 1.4
that yield important features in comparison with prior Ghostty variations.

The largest win got here from a shocking discovery: on macOS, the kernel
caps each learn from a pty at about 1 KiB irrespective of how massive the learn
buffer is. Previously, Ghostty processed every learn because it arrived, so per-read
overhead was paid each kilobyte, and this system writing output sat
blocked whereas we parsed. Ghostty now drains the pty on one thread whereas
parsing on one other, elevating end-to-end I/O throughput by 25% to 55%
on macOS (M4 Max, plain and Unicode textual content) over Ghostty 1.3.x.

VT processing itself can be a lot sooner. In parser benchmarks, plain
ASCII textual content went from 128 MB/s to 725 MB/s (5.7x), CJK textual content bought 3.4x
sooner, and a 2.6 GB dataset of real-world terminal recordings
from asciinema is processed about 25% sooner.
Together, these adjustments took cat-ing a 150 MB textual content file on macOS from
1.5 seconds to 566 milliseconds.

Other notable enhancements:

• Resize: resizing a terminal with a big scrollback is about 6x
  sooner (120×80 with 10,000 traces of scrollback), and 3x to 5x sooner
  with historical past stuffed with CJK textual content or emoji.
• Rendering: the renderer holds the terminal lock 2.7x to 11x
  much less per body, leaving extra time for the I/O thread throughout heavy
  output.
• Copy and search: formatting terminal contents as plain textual content, HTML,
  or VT, which backs clipboard copy, write_screen_file, and scrollback
  search, is 1.5x to 8x sooner.
• Launch (macOS): about 15% sooner from launch to seen window, and
  27% sooner to the primary rendered body.
• Idle power: on macOS, the renderer’s show hyperlink now sleeps when
  there’s nothing to attract. On GTK, hidden tabs cease rendering, matching
  macOS.
• Large OSC sequences: OSC 52 clipboard payloads parse about 30x
  sooner, and even quick sequences like title adjustments are about 6x
  sooner.

The GTK app has a brand new rendering pipeline. It now not makes use of GtkGLArea.
Instead, the renderer attracts with EGL by itself thread, exports every body
as a DMABUF, and fingers it to GTK to show. Rendering is now
triple-buffered, which ought to enormously scale back tearing, and no OpenGL calls
run on the principle thread anymore, which allow us to take away numerous
workarounds.

The most seen result’s crisp textual content below fractional scaling. Text and
box-drawing characters are now not blurry with fractional show
scaling comparable to 125% or 150% (#1938 ). We fastened this as soon as earlier than, nevertheless it
got here again after upstream GTK adjustments. Ghostty now renders on the window’s
true fractional scale, so each rendered pixel maps to precisely one pixel
on display.

The new render floor wants a system EGL library (see
Changes for Package Maintainers).
On GPU drivers that may’t export DMABUFs, Ghostty falls again to copying
frames by way of the CPU, which is slower however works.

Ghostty now implements the
Kitty clipboard protocol
(OSC 5522) on each macOS and GTK. Ghostty 1.3 may parse the protocol
however did not implement it.

OSC 52 can solely learn and write plain textual content. The Kitty clipboard protocol
lets applications working within the terminal learn and write any form of clipboard
information, comparable to photos or HTML, and lets them choose among the many codecs on the
clipboard. Programs also can allow paste occasions (mode 5522), which inform
this system what codecs a paste accommodates so it may learn the one it
needs. This is how a terminal program can settle for a pasted picture, for
instance.

Clipboard entry follows the prevailing clipboard-read and
clipboard-write configurations. By default, reads immediate for permission
and writes are allowed. The permission immediate exhibits a preview of the
clipboard contents, together with photos. Programs that ship a password can
have your reply remembered for the remainder of that terminal session. A brand new
clipboard-write-limit-bytes configuration limits the dimensions of a single
write (default 64 MiB). A write over the restrict fails and leaves the
clipboard untouched.

You can now rearrange splits on GTK by dragging them, matching the macOS
function launched in Ghostty 1.3. When a tab has two or extra splits, every
break up exhibits a drag deal with on the high. Grab the deal with and drop the break up
onto every other break up, together with splits in different tabs and home windows. An
overlay exhibits which aspect of the goal break up it’s going to land on. The terminal
contents, working listing, and working processes all transfer with it.

A brand new drag-handle configuration controls when drag handles are proven on
each macOS and GTK: auto (default), at all times, or by no means. With by no means,
splits cannot be rearranged with the mouse. Hiding the handles was a
frequent request from customers who discovered them in the way in which.

On GTK, splits can solely be dropped onto different splits. Dragging a break up out
to create a brand new tab or window is macOS-only.

Ghostty 1.4 contains dozens of enhancements to core terminal emulation. We
now run esctest, Thomas Dickey’s
terminal conformance suite, in opposition to Ghostty’s terminal core in CI.
Alongside that, we fastened many variations from xterm in cursor motion
inside margins, tab stops, character units, mode reviews, and extra. You
can discover the total checklist of associated adjustments within the
terminal capabilities part.

Ghostty additionally helps a number of new sequences, together with delicate terminal reset
(DECSTR), prolonged cursor place reviews (DECXCPR), backarrow key mode
(DECBKM), and display dimension reviews in characters (CSI 19 t). Programs can
additionally now ask whether or not the terminal is seen utilizing
visibility reports
(mode 2033), to allow them to cease rendering whereas hidden.

Keyboard encoding additionally matches xterm extra intently, with fixes for
modifyOtherKeys mode 2 and legacy Alt-as-Escape encoding of non-ASCII
keys.

Two new sequences are disabled by default as a result of they are often abused by
untrusted applications, together with ones working on a distant machine:

# Allow applications to resize the window (CSI 8 t)
vt-window-resize-allowed = true

# Allow applications to request display checksums (DECRQCRA)
vt-xt-checksum-report = true

Ghostty 1.2 launched SSH shell integration features
as a piece in progress. In Ghostty 1.4, they’re backed by a brand new
ghostty +ssh CLI motion: a drop-in ssh wrapper that prepares the
distant session for Ghostty after which runs the actual ssh along with your
arguments forwarded unchanged.

ghostty +ssh [email protected]


alias ssh='ghostty +ssh --'

Before connecting, +ssh installs Ghostty’s terminfo on the distant host
so the correct xterm-ghostty TERM worth can be utilized, and forwards
COLORTERM, TERM_PROGRAM, and TERM_PROGRAM_VERSION. If the terminfo
set up fails (for instance, tic is not out there on the distant), it falls
again to TERM=xterm-256color. Flags comparable to --terminfo=false,
--forward-env=false, and --verbose management every step.

The ssh-env and ssh-terminfo shell integration options (nonetheless opt-in)
now name +ssh too. Previously, every shell integration carried its personal copy
of this logic, which made up roughly a 3rd of our shell integration
scripts. Now bash, zsh, fish, elvish, and Nushell all behave identically,
and you will get the identical habits from scripts or anyplace else by calling
ghostty +ssh instantly.

The terminfo set up itself can be extra dependable. Ghostty now at all times
installs its personal bundled terminfo moderately than accepting no matter
xterm-ghostty entry the distant already has, and it reinstalls
mechanically when a Ghostty replace adjustments the terminfo. It additionally now not
wants infocmp or Ghostty’s terminfo on the native machine. Installs are
cached per host and port, so two machines behind one handle now not
share a cache entry. And ssh-env now not silently overrides SetEnv
entries in your ~/.ssh/config (#11518 ).

The +ssh-cache command that manages this cache now takes positional
locations (ghostty +ssh-cache [email protected]) and has a brand new
--prune=30d flag. See the breaking changes if you happen to
script in opposition to +ssh-cache.

macOS: The minimal required macOS model for Ghostty 1.4 stays
unchanged (macOS 13 Ventura). Ghostty is now suitable with macOS 27.

GTK: Ghostty 1.4 requires GTK 4.18 and libadwaita 1.7, up from
GTK 4.14 and libadwaita 1.5 in Ghostty 1.3. This aligns with our
GTK/Adwaita version policy.
Notably, Ubuntu 24.04 LTS would not meet this requirement. Systems with
older GTK or Adwaita variations can work round this requirement by utilizing an
older model of Ghostty or the Flatpak bundle. #14330

OpenGL (GTK): The minimal required OpenGL model stays 4.3, however
Ghostty now renders by way of EGL as a substitute of GTK’s OpenGL widget. This
ought to be invisible for almost everybody, but when Ghostty fails to begin
with an EGL error, please be certain your GPU driver gives a working
EGL implementation.

We beforehand introduced that Ghostty 1.4 would require macOS 14.
Nothing pressured our hand to do that on this launch, so we stored macOS
13 help. We nonetheless plan to drop macOS 13 in a future launch. Apple
dropped safety help for macOS 13 within the fall of 2025, so we
suggest upgrading regardless.

The following behaviors have modified in 1.4.0:

• copy-on-select has been reworked and now accepts none, major,
  clipboard, or each. The which means of clipboard has modified: it
  beforehand copied to each the choice clipboard and the system
  clipboard, and now copies solely to the system clipboard. If you set
  copy-on-select = clipboard and need the previous habits, change it to
  each. #12600 #12604
• macOS: copy-on-select now defaults to none (beforehand true), so
  deciding on textual content now not copies it anyplace and middle-click paste of the
  choice now not works by default. To restore the 1.3 habits, set
  copy-on-select = major. Note that an express copy-on-select = true
  on macOS now copies picks to the system clipboard, which is
  completely different from 1.3. #12600 #12604
• macOS: cmd+arrow_up and cmd+arrow_down now run jump_to_prompt once more,
  matching Terminal.app and Ghostty 1.2. In 1.3, these keys have been hardcoded
  to scroll to the highest and backside and could not be rebound. To maintain the 1.3
  habits, set keybind = cmd+arrow_up=scroll_to_top and
  keybind = cmd+arrow_down=scroll_to_bottom. #12245
• GTK: The default ctrl+shift+page_up and ctrl+shift+page_down keybinds
  now transfer the present tab left and proper (move_tab), matching Firefox,
  GNOME Terminal, and VS Code. jump_to_prompt moved to
  ctrl+shift+arrow_up and ctrl+shift+arrow_down, so applications working in
  the terminal now not obtain these keys. If a program you utilize wants
  them, unbind them with keybind = ctrl+shift+arrow_up=unbind and
  keybind = ctrl+shift+arrow_down=unbind. #4998 #12458

The checklist beneath accommodates deprecations that stay suitable at present by way of
a compatibility layer, however could break in a future launch if they’re
ignored:

• scrollback-limit has been renamed to scrollback-limit-bytes, to make
  room for the brand new scrollback-limit-lines. #13473
• copy-on-select = true is changed with copy-on-select = major on
  Linux and FreeBSD, or copy-on-select = clipboard on macOS.
  copy-on-select = false is changed with copy-on-select = none.
  #12600 #12604

There isn’t any set timeline to take away these deprecations, however we suggest
adapting to the brand new configurations sooner moderately than later to keep away from
any doable disruptions sooner or later.

• Scrollback historical past is now transparently compressed whereas the terminal
  is idle, decreasing the bodily reminiscence utilized by compressed scrollback by
  70% to 90% for typical textual content. Compression is out there on macOS and 64-bit
  Linux and may be disabled with the brand new scrollback-compression
  configuration. Because of this, the default scrollback restrict has been
  raised from 10 MB to 50 MB, which on common nonetheless makes use of much less reminiscence than
  a full scrollback did beforehand. #13264
• A brand new configuration scrollback-limit-lines limits scrollback by quantity
  of traces as a substitute of bytes. The current scrollback-limit configuration
  has been renamed to scrollback-limit-bytes (the previous title continues to
  work). If each are set, the primary restrict reached applies, and each settle for
  limitless. #13473
• copy-on-select now accepts none, major, clipboard, and each
  and now not impacts middle-click paste (see middle-click-action).
  clipboard now copies solely to the system clipboard, so use each for the
  earlier habits. The default on macOS is now none. See the
  breaking changes for migration particulars. #12600
• A brand new configuration middle-click-action configures the habits of
  middle-clicking: primary-paste (default) pastes from the choice
  clipboard, clipboard-paste pastes from the system clipboard, and
  ignore does nothing. #12478
• A brand new binding motion move_tab_to_new_window strikes the present tab into
  a brand new window of its personal. It can be out there within the command palette.
  #2630
• A brand new CLI command +explain-config prints the documentation for a
  configuration possibility or binding motion, e.g.
  ghostty +explain-config font-size. #11546
• The +explain-config and +show-config CLI instructions now web page their
  output by way of $GHOSTTY_PAGER or $PAGER (falling again to much less) when
  run interactively. Paging may be disabled with --no-pager or by setting
  the pager to an empty worth. #11940
• A brand new configuration drag-handle controls when the break up drag handles
  are proven: auto (default), at all times, or by no means. #13706 #13709
• Scrollback search now wraps round when navigating previous the primary or
  final match. #11449
• A brand new configuration link-osc8 (default true) may be set to false to
  disable OSC 8 hyperlinks solely. Disabled OSC 8 hyperlinks will not be
  highlighted, previewed, copied, or opened. #13634

  surroundings variable that uniquely identifies the terminal they’re
  working in. #12027
• The right-click context menu now has a “Close Split” merchandise. #11173

• I/O throughput is 25% to 55% greater on macOS by studying from the pty
  concurrently with parsing beforehand learn output. #13209
• VT processing is considerably sooner throughout the board. Plain textual content is up
  to ~6x sooner, real-world output (measured in opposition to a big asciinema
  dataset) is ~24% sooner, grapheme-heavy output is ~3x sooner, and DEC
  particular graphics (line drawing), repeated characters (REP),
  hyperlink-heavy output, and scroll areas are all sooner. #13220
  #13226 #13231 #13294 #13625 #13826 #14356
• Large OSC sequences, comparable to OSC 52 clipboard writes, are parsed ~30x
  sooner and small OSC sequences, comparable to title adjustments, ~6x sooner.
  #14011 #13565
• Resizing with reflow is ~6x sooner with massive scrollback and 3x to 5x
  sooner with scrollback heavy in vast characters comparable to CJK or emoji.
  #13537 #13827
• Terminals use considerably much less reminiscence. A brand new terminal now makes use of ~16 KiB
  of bodily reminiscence for its display as a substitute of 128 KiB on macOS, each
  terminal web page makes use of 30% much less reminiscence, and reminiscence free of scrollback
  (comparable to by clearing it) is now returned to the working system.
  #13240 #13245 #14130 #14137 #14138
• Kitty graphics are sooner. Large picture transfers are parsed in bulk utilizing
  SIMD, zlib-compressed photos decompress ~17% sooner, pixel format
  conversion avoids an additional copy, and the per-frame value of drawing photos
  is way decrease, particularly with Unicode placeholder photos on display or
  lengthy scrollback. #13270 #13281 #13987 #14422 #14780 #14789
• Formatting terminal contents is 1.5x to 8x sooner, which accelerates
  clipboard copy (plain, HTML, and VT), write_screen_file and associated
  actions, and scrollback search. #13587
• The renderer holds the terminal lock 2.7x to 11x much less time per body,
  and glyph and font lookups are sooner. #13227 #14300 #14301 #14420

  to a file. #13519
• Bundled themes up to date to release-20261019-151001-86a776d.
  This provides 356 new themes and renames or removes none. The colours of 10
  current themes modified upstream: Adwaita, Adwaita Dark, Atom One Light,
  Catppuccin Frappe, Catppuccin Latte, Catppuccin Macchiato, Catppuccin
  Mocha, Cursor Dark, Dark Modern, and Electron Highlighter.
• Fix configuration parsing silently ignoring all settings after a remark
  or clean line that occurred to finish at an inner buffer boundary. This
  sometimes solely affected lengthy configuration information. #13638
• Fix a efficiency degradation the place, after a protracted uptime, the renderer
  rebuilt its full terminal state on each body. #13585
• Fix the mechanically created configuration file being empty as a substitute of
  containing the configuration template. #13774
• +edit-config works when $EDITOR or $VISUAL accommodates arguments,
  comparable to zed --new. #11897
• adjust-cursor-height works once more. #13225
• Mouse choice enhancements: dragging after a ctrl/cmd triple-click
  output choice now extends the choice by command output, autoscroll
  stops when the display switches (e.g. to the alternate display), a power
  contact on macOS selects the phrase on the press location with out beginning a
  drag, and releasing a drag now not prompts a hyperlink or immediate click on.
  #12830
• Double-click phrase choice now not continues throughout exhausting line breaks,
  and double-clicking both half of a large character (comparable to CJK) selects
  the entire phrase. #14354 #14391
• Wide characters on the edges of a range are actually constantly rendered
  as chosen and included when copying, together with when the vast character
  wraps onto a brand new inner web page. #14632 #14651
• Triple-click line choice now not pulls in neighboring immediate textual content
  when clicking clean cells between OSC 133 immediate boundaries. #14553
• Link detection and double-click choice now not merge immediate textual content
  with the command textual content subsequent to it when shell integration is lively.
  #12435
• File paths opened with cmd/ctrl-click now not embrace trailing
  areas, which broke opening paths printed by some TUIs. #13505
• Mouse releases are actually reported to this system that obtained the mouse
  press when clicking at a shell immediate with click-to-move enabled. This
  fixes double-click choice in applications like fzf’s ctrl+r historical past
  search. #14710
• Shell redraws after a resize are now not processed on the previous terminal
  dimension. This fixes one reason behind duplicated or misplaced prompts after
  resizing. #14706

Ghostty 1.4 introduces full localization for the command palette and provides
help for 4 new languages:

• Basque
• Belarusian
• Danish
• Serbian (Cyrillic and Latin scripts)

Localization is maintained by volunteer contributors. If you wish to
assist localize Ghostty in your language, please open a dialogue on the
GitHub repo. Thank you to all of the volunteers who contributed to Ghostty’s
localization!

• Ghostty now requires Zig 0.17 to construct. #14518 #14519
• GTK builds now require GTK 4.18 and libadwaita 1.7, up from
  GTK 4.14 and libadwaita 1.5. Builds in opposition to older headers fail at
  compile time, and Ghostty exits at startup if older libraries are
  loaded at runtime. #14330
• GTK builds now hyperlink the system EGL library (pkg-config egl, normally
  supplied by libglvnd or Mesa) for the brand new renderer. At runtime, Ghostty
  makes use of GTK’s EGL show when it may, and in any other case wants an EGL driver
  that helps the surfaceless platform. #14052 #14636
• A brand new -Dinstalled-exe-path construct possibility units absolutely the executable
  path written into the desktop file, D-Bus companies, and systemd consumer
  service. Previously this path got here from the set up prefix. Without the
  possibility, these information now title ghostty alone, which systemd solely finds in
  /usr/bin or /usr/native/bin, so set it for every other prefix.

As with 1.3, libghostty is not instantly a part of the Ghostty 1.4 launch.
But a big a part of the 1.4 growth cycle went into libghostty, so
here is an replace.

Over the previous 6 months, the C API for libghostty-vt has grown from a
parser and some encoders into a whole terminal emulator API, adopted
by dozens of free and industrial terminal emulators utilized by thousands and thousands of
folks. It’s exhausting to quantify precisely, however the variety of folks utilizing a
libghostty-based terminal is confidently a number of occasions the variety of
folks utilizing the Ghostty GUI.

libghostty-vt now builds for macOS, Linux, Windows (MSVC and GNU), FreeBSD,
Android, iOS, and WebAssembly, and CI repeatedly verifies each one among
these targets. The objective is for libghostty-vt to be usually usable in every single place,
inside cause, so if you’d like extra goal help, tell us!

It’s additionally simpler to combine libghostty-vt into current construct techniques.
There’s CMake help, Nix packaging, an xcframework, and a supply
tarball, along with the prevailing pkg-config file. libghostty-vt no
longer wants libc++, and it may construct freestanding.

The API continues to be marked as a piece in progress and broke compatibility
a number of occasions throughout this cycle, so anticipate extra breaking adjustments earlier than
a tagged launch. The API documentation
and the Zig, C, C++, Swift, and WebAssembly examples
(now over 30) are stored updated with fundamental.

We’re going to do a closing move over the C API, break ABI another time,
after which probably tag a libghostty 1.0 launch very quickly.

Ghostty is a non-profit project, fiscally sponsored
by Hack Club.
All of our funds are public on HCB,
so you possibly can see precisely the place each greenback goes.

During the 1.4 cycle, we paid $41,820 to contributors below contract and
spent about $1,260 on roads comparable to web site internet hosting.

I’m blissful to share that we have now signed our first two 12-month contracts,
which give contributors secure, long-term paid work on Ghostty and assist
guarantee the continued stability and sustainability of the undertaking:

• @trag1c is Ghostty’s head of operations.
  He manages the group on GitHub and Discord, coordinates our
  volunteer translators, and maintains numerous different vital undertaking
  techniques.
• @vancluever works on numerous Ghostty
  subsystems. In this cycle, he led the improve to Zig 0.16, moved the
  construct off Zig’s deprecated @cImport, up to date the bundled Fontconfig,
  and extra. He’s additionally the writer of
  z2d, the 2D graphics library Ghostty
  makes use of to attract box-drawing characters and different sprite glyphs.

If you’d prefer to help Ghostty, please go to our sponsorship page.

The major focus of the roadmap continues to be libghostty performance,
stability, and portability. During the final launch cycle, I stated I aimed to
tag a libghostty launch. We have not finished that but, however I’m assured we are going to
accomplish that earlier than Ghostty 1.5.

libghostty is a undertaking that continues to be the tide that lifts all boats.
libghostty enhancements tie on to Ghostty GUI enhancements in addition to
dozens of different massive initiatives within the ecosystem. As extra massive initiatives undertake
libghostty, libghostty tends to get extra testing and a spotlight, and this
creates a cycle that yields essentially the most acquire for terminal emulators in every single place.

macOS and GTK builds of Ghostty have proficient, succesful maintainer groups that
are persevering with to enhance them, so they are not uncared for by any means!
As a undertaking, we have determined to drop any roadmap for Windows help within the
Ghostty GUI. libghostty absolutely helps Windows (and we check it in CI), and the
official stance now could be that downstream initiatives ought to use that.

Our launch cycle stays 6 months. This launch was delayed by one month,
however Ghostty 1.5 is deliberate for March 2027. libghostty could have a separate
launch cycle.
