I am excited beyond description to lift the veil on what we have been working on in 2026:
Please meet ggsql! A new extension of the SQL language for creating visualisations using the grammar of graphics. Read all about it in the blog post https://opensource.posit.co/blog/2026-04-20_ggsql_alpha_release/
ggsql has been created as a cross-team effort at @npub1e58…ey66 between me, @npub18q0…ja80 and @npub1s0n…vs9c and while still in alpha, we are super proud at what it can already do.
Please take it for a spin — we'd love any feedback ❤️

I've been hard at work updating our entire text rendering stack in #RStats
Read about the relevant improvements in systemfonts, textshaping, and marquee in this rundown.
The tldr; is that marquee is now ready for primetime
Other large quality-of-life improvements are build-in support for web fonts and easier access to fonts that aren't installed on the system.
Put `require_font(<font name>)` in your script and it will fetch and load it if it isn't already available
