Ghostty 1.2.1

Ghostty 1.2.1 features two weeks of work with changes from 13 contributors over 62 commits. This is a patch release primarily focused on fixing issues introduced in the 1.2.0 release. It includes a small handful of improvements, too.

Highlights

Font Rendering Improvements

PRs: GH-8563 GH-8580 GH-8738 GH-8720 GH-8847

Ghostty 1.2.0 contained a substantial overhaul of the font rendering system. As expected with such a large change, some issues were discovered outside of our testing. Ghostty 1.2.1 addresses many of these issues.

An overview of the changes:

• Nerd Font icons are now larger and better matched in size relative to each other, making better use of available cell space. Icons wider than a single cell are now left-aligned rather than centered across cells.
• CJK characters no longer appear oversized when using wide-aspect primary fonts. The IC width (ideographic character width) is now upper-bounded by measuring the overall bounding box of ASCII characters.
• Glyph constraints are now applied before thickening and centering operations, ensuring that icon sizes and positions are consistent regardless of font size, thickening strength, or display DPI.
• Fixed bugs in Nerd Font patch extraction where rules were applied to wrong glyphs due to codepoint offset issues, and irrelevant patch sets were incorrectly included.
• Improved FreeType glyph measurements to ensure glyphs are measured with the same hinting as they are rendered.

Shell Integration Adds ghostty to PATH

PR: GH-8976

Shell integration now automatically adds GHOSTTY_BIN_DIR to your PATH, making the ghostty binary available in many shells without additional configuration.

Ghostty previously (and still) adds ghostty to your PATH prior to executing the shell, but many shell configurations reset PATH. This change adds an additional layer as part of the shell integration scripts to increase the chances that ghostty is available in your shell.

This is supported for bash, zsh, fish, and elvish.

Mouse Scroll Multiplier for Precision Scrolling Devices

PR: GH-8927

The mouse-scroll-multiplier configuration now supports precision scrolling devices like Apple trackpads. You can now independently control multipliers for both discrete (mouse wheel) and precision (trackpad) scrolling, making navigation through large scrollback buffers smoother and more predictable across different input devices.

Examples:

# Apply the same multiplier to both precision and discrete
mouse-scroll-multiplier = 3

# Apply different multipliers (order doesn't matter)
mouse-scroll-multiplier = precision:0.1,discrete:3

# Apply only to precision, use default for discrete
mouse-scroll-multiplier = precision:2

The default precision multiplier is 0.1 while the default discrete multiplier remains 1.

Changes for Package Maintainers

• Ghostty now limits builds to 32 cores on Linux to workaround a known memory corruption bug in Zig, allowing Ghostty to be reliably built on machines with more than 32 cores. This bug has been resolved in Zig but won't be backported to the 0.14.x series that Ghostty 1.2.x relies on. GH-8925

Roadmap

We believe there will likely be a 1.2.2 release at some point to continue to address minor issues introduced by the changes in 1.2.0 and 1.2.1. A possible 1.2.2 release is probably going to be a mid-cycle release (months away) rather than a quick follow-up.

As it stands, the 1.2.x series has been very stable and we don't feel a rush to release any more bugfix releases. We've heard very positive feedback about the release and we're happy to see people enjoying the new features.

See the roadmap from the 1.2.0 release notes for bigger picture plans.
