Ghostty 1.4.0 ghostty.org

Ghostty 1.4.0, released by the Ghostty maintainers after seven months of work by 172 contributors, adds full support for the Kitty graphics specification, including animation, and compresses scrollback to reduce physical memory use by 70%–90% for typical text. The release also reports faster terminal processing and lower memory use, improves SSH integration, and adds a new GTK rendering pipeline; it fixes multiple security vulnerabilities, including issues that could allow malicious terminal output to crash the app or access files.
