Ghostty 1.4 is now out! Full Kitty graphics with animation (the first terminal besides Kitty to do it), scrollback compression for much lower memory usage, macOS 27 support, a new OpenGL renderer on Linux, ghostty +ssh, big performance gains, and hundreds more changes.
The highlights:
- Scrollback compression: scrollback compresses ~90+% on average, meaning your terminals use that much less live memory
- Huge memory savings across the board: no single large thing, just lots of good improvements lowers memory usage everywhere, netting anywhere from 50 to 90% less memory usage depending on workload
- Kitty graphics is now 100% complete, including animation and relative placements, after a full conformance pass against the spec and Kitty itself
- The Kitty clipboard protocol, with an image preview when a program asks to read your clipboard
- Split drag and drop on Linux, including between windows
- ghostty +ssh installs terminfo on remote hosts automatically, so things just work over SSH
- Lots of terminal emulation accuracy fixes
This release is 7 months of work from 172 contributors over 2,889 commits. It also fixes 10 security advisories, so please update.
