What is lifecycle?

lifecycle gave the tidyverse the word superseded, then spent years tuning who gets warned

lifecycle defines the deprecation vocabulary the tidyverse signals with - deprecated, superseded, experimental - and the functions that emit those warnings. The design settled early; nearly all work since has been about warning frequency and attribution, deciding who is responsible for a deprecated call and how often they should hear about it.

What is pkgdown?

pkgdown now generates llms.txt and a markdown copy of every documentation page

pkgdown builds the documentation sites for most R packages. The 2.1 line was about format and appearance - Quarto vignettes, a light and dark switch, self-hosted assets instead of CDN fetches. The 2.2 line changed audience: build_llm_docs() emits an llms.txt at the site root and a markdown version of every page, on by default.

lifecycle gave the tidyverse the word superseded, then spent years tuning who gets warned

◆ Current state

lifecycle defines the deprecation vocabulary the tidyverse signals with - deprecated, superseded, experimental - and the functions that emit those warnings. The design settled early; nearly all work since has been about warning frequency and attribution, deciding who is responsible for a deprecated call and how often they should hear about it.

◆ Where it's heading

The consistent problem is blame. Deprecation warnings are useless if they fire at the user of a package rather than its author, so successive releases narrowed the audience: warn only when the deprecated call comes from the package being tested, name the package that likely triggered an indirect usage, and stop repeating. Version 1.0.5 admits the eight-hourly throttle never actually worked and replaces it with once per session.

◆ Prediction

Expect further work on the linting side, which is where the recent additions have gone, rather than on the signalling API; signal_stage() being reduced to a no-op suggests staged signals are not coming back.

pkgdown now generates llms.txt and a markdown copy of every documentation page

◆ Current state

pkgdown builds the documentation sites for most R packages. The 2.1 line was about format and appearance - Quarto vignettes, a light and dark switch, self-hosted assets instead of CDN fetches. The 2.2 line changed audience: build_llm_docs() emits an llms.txt at the site root and a markdown version of every page, on by default.

◆ Where it's heading

Two audiences are now being served from one build. Human-facing work continues in small increments - dark-mode plot filtering, new translations, a local http server so search works in preview - while the new machine-facing output is opt-out rather than opt-in. The default matters more than the feature: thousands of package sites will start emitting llms.txt without their maintainers choosing to.

◆ Prediction

Expect the markdown output to gain the same configuration surface the HTML has, and the llms.txt contents to get more selective as maintainers discover what ends up in it; a way to exclude individual pages is the obvious next request.
