From Ghostty

Ghostty 1.2.3 features two weeks of work with changes from 6 contributors over 27 commits. This is a patch release primarily focused on fixing issues introduced in the 1.2.x series.

This release contains a critical fix for a deadlock scenario that can happen on all platforms. We highly recommend that all users on prior 1.2.x versions upgrade to this version at their soonest convenience.

Highlights
macOS Titlebar Tabs Improvements

PRs: GH-9090 GH-9163 GH-9168 GH-1787 GH-1813 GH-1945 GH-8612

Ghostty 1.2.3 includes multiple fixes for macos-titlebar-style = tabs, including many issues that have existed since pre-1.0! Additionally, multiple Tahoe-specific (macOS 26) bugs related to this configuration were also fixed, since Tahoe introduced a dramatically different tab bar.

An overview of the changes:

  • Fixed title misalignment and clipping in tab titlebar style.
  • Corrected titlebar coloring in fullscreen mode when titlebar tabs are enabled.
  • Resolved issues where theme changes would cause the titlebar to lose styling.
  • Fixed truncated title appearing in top-left corner when using tab titlebar style in fullscreen.
  • Improved behavior with macOS 26 native fullscreen and titlebar tabs.
Font Rendering Improvements

PRs: GH-9142 GH-9152 GH-9160

Ghostty 1.2.3 continues to include a number of refinements to the rewritten font rendering system introduced in 1.2.0. The changes in Ghostty 1.2.3 focus primarily on icon glyphs (e.g. Nerd Fonts). Ghostty 1.2.3 users should see better sized icons in all scenarios.

This addresses all currently known font rendering issues, particularly those stemming from the rewritten renderer in 1.2.0. Note that there are still other known font-related issues but they either predate Ghostty 1.2 or are otherwise unrelated to font rendering (and are instead related to font discovery, loading, shaping, etc.).

Changes for Package Maintainers
  • A new -Demit-themes (default true) build option has been added to build Ghostty without any bundled themes. This was added for packagers who are sensitive to licensing issues that may exist in our upstream dependency. We're looking into this in more detail but this is meant as a short-term solution to avoid the themes entirely if there are concerns. GH-9288
Roadmap

We don't plan on releasing any further 1.2.x releases, except in the circumstance that a critical issue is found. The 1.2.x series has already been very stable, and we believe 1.2.3 addresses the remaining major issues that exist.

That doesn't mean Ghostty is without bugs, of course! We'll continue to fix bugs and improve features, but unless those bugs are critical, we'll hold their release until Ghostty 1.3.0.
