dplyr 1.2.0 is out now and we are SO excited!
- `filter_out()` for dropping rows
- `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools
These are huge quality of life wins for #rstats!

I had such a good time speaking at @atds.space this year! All the talks were great & the videos are now online, including mine on demystifying AI code assistance, i.e. what is actually going on when you use a tool like Claude Code or GitHub Copilot or Positron Assistant?!

Whenever I read discourse on AI energy/water use that focuses on the "median query," I can't help but feel misled. Coding agents like Claude Code send hundreds of longer-than-median queries every session, and I run dozens of sessions a day.

For dplyr releases, we send a PR any time we break an #rstats package. This release advances a lot of deprecated functions, triggering issues in many old packages!

I am struggling with what might be a generational experience. The gulf war was pretty politically formative for me. It’s not history so much as memory this time.
It is destabilizing to see almost the exact same gameplan but this time without the guardrails that at the time I took for granted.
