Ghostty 1.4.0, released on October 27, 2026, is a major update that brings significant performance and memory improvements, along with a 100% complete implementation of the Kitty graphics protocol including animation and relative placements, a first among non-Kitty terminals. The update features improved SSH integration, GTK rendering enhancements, and expands support to macOS 27 while maintaining compatibility back to macOS 13. Memory compression for scrollback reduces physical memory use by 70%-90%, allowing an increase in scrollback limit from 10 MB to 50 MB. Parsing speeds for ASCII and complex text have greatly increased, improving throughput by up to 5.7x in benchmarks. The GTK version moves to EGL rendering with triple buffering, providing crisper text with fractional scaling support. Ghostty now supports the full Kitty clipboard protocol, enhancing clipboard interactions beyond plain text. Splits can be rearranged by dragging across tabs or windows on macOS, and terminal emulation features have been enhanced with new sequences and better xterm compatibility. The new ghostty +ssh CLI action streamlines remote session setup via SSH, including automatic terminfo installation. Localization has been expanded to support four new languages, maintained by volunteers. The libghostty terminal emulator API has matured, supporting multiple platforms and improved integration options, although it remains a work in progress. The release incorporates contributions from 172 contributors and over 2,889 commits during seven months of development.
