Quarto 1.10 shipped Friday. The highlights page lists one feature. The changelog lists 74. Mostly preview friction: stale pages, _brand.yml ignored until restart, format: changes needing two renders. If you work in Positron, that's your whole day. A boring release. Best kind.

I'm happy to share `ir`, a new command-line tool for running portable R scripts and Quarto documents. It's inspired by my two favorite parts of `uv`: self-describing scripts and tools you can run without installing first. opensource.posit.co/blog/2026-07...
