rhun 0.19.1 is out. This is a small bug-fix release.
Claude Code and Codex sessions now appear when you use a custom configuration directory. Switching agent profiles also clears up the brief display of sessions cached from the previous profile. Existing worktree history is preserved.
Hover cards now use one background, including behind fenced code.
I also released LSP 0.3.5. Semantic coloring no longer rescans a long line for every token. In a benchmark with 8,000 tokens on one 40 KB line, conversion fell from roughly a second to 0.38 ms on an M1 Max. This measures token conversion on that machine.
rhun is a small, open-source code editor. It has extensions now, and I d love to see what people make with them.
We ve added Claude Code and Codex skills for building and testing your own extension, plus a skill for porting open-source VS Code extensions. Describe the tool you want, then work on it with your agent. Rust/Go templates, examples and CLI commands give you a place to start and a way to share it.
What s the oddly specific extension you ve always wanted?
The last release update I posted here was 0.17.9. We're now at 0.17.14, with a few additions and a lot of work on the small things you feel while editing.
