pkgdown vs Skipper: at a glance
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.
What is Skipper?
Skipper tags a release per commit, and this time one of them is a new load-balancing algorithm.
Zalando's HTTP router publishes a GitHub release for essentially every merged commit, so the feed reads as a commit log: doc corrections, dependency group bumps and small refactors each get their own version tag. Underneath that noise, v0.27.53 adds leastRequests, a load-balancing algorithm that routes to the endpoint with the lowest inflight-requests-to-weight ratio and breaks ties with smooth weighted round-robin. The surrounding releases are documentation for data client latency metrics, a jwtValidation behaviour clarification, and a Valkey ratelimit refactor.

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.

Skipper tags a release per commit, and this time one of them is a new load-balancing algorithm.
◆ Current state
Zalando's HTTP router publishes a GitHub release for essentially every merged commit, so the feed reads as a commit log: doc corrections, dependency group bumps and small refactors each get their own version tag. Underneath that noise, v0.27.53 adds leastRequests, a load-balancing algorithm that routes to the endpoint with the lowest inflight-requests-to-weight ratio and breaks ties with smooth weighted round-robin. The surrounding releases are documentation for data client latency metrics, a jwtValidation behaviour clarification, and a Valkey ratelimit refactor.
◆ Where it's heading
The routing layer is getting more load-aware. leastRequests picks endpoints by observed inflight load rather than by position or hash, which suits backends with uneven per-request cost — and it arrives alongside newly documented route-sync latency metrics, so both the routing decision and the route-loading path are becoming measurable. The dependency and CI churn filling the rest of the feed is automated maintenance on a mature proxy, not a signal about direction.
◆ Prediction
Expect leastRequests to pick up tuning as production traffic exercises it, and the release-per-commit tagging to continue burying that kind of change among doc fixes. Whether it becomes a recommended default over roundRobin is not something these entries indicate.
