kwb.pkgbuild vs q2
A side-by-side editorial comparison of kwb.pkgbuild and q2 — release velocity, themes, recent moves, and the top alternatives to consider.
kwb.pkgbuild vs q2: at a glance
What is kwb.pkgbuild?
kwb.pkgbuild's CI templates went four years without a refresh, then had to be rebuilt for current runners
kwb.pkgbuild automates R package setup at Kompetenzzentrum Wasser Berlin to a house style, and its main deliverable is the GitHub Actions templates it installs into new packages. Between October 2022 and May 2026 there were no releases. During that gap the templates aged past the point of working on current GitHub-hosted runners.
What is q2?
Two surfaces the original Quarto never had: llms.txt output and a live-share preview.
q2 is the Quarto team's Rust reimplementation, shipping as a statically linked single binary with signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence has held at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. Until v0.22.0 the programme read as pure parity work against the existing Quarto — investigate, record design decisions, write tests red, implement in numbered phases. That release is the first to ship capability the original toolchain does not have.

◆ Current state
kwb.pkgbuild automates R package setup at Kompetenzzentrum Wasser Berlin to a house style, and its main deliverable is the GitHub Actions templates it installs into new packages. Between October 2022 and May 2026 there were no releases. During that gap the templates aged past the point of working on current GitHub-hosted runners.
◆ Where it's heading
0.3.0 is a catch-up release rather than a direction change: action versions bumped to checkout@v5, upload-artifact@v4 and codecov-action@v5 to clear the Node.js 20 deprecation, deprecated r-lib/actions@master references replaced with @v2, the retired ubuntu-20.04 runner swapped for ubuntu-latest, and the archived r-hub/sysreqs step replaced with setup-r-dependencies@v2, which also brings dependency caching. One fix stands out: a stale conditional comparing runner.os to the string 'Linux (no, try without!)' had been silently disabling the Linux system-dependency step.
◆ Prediction
For a package whose product is CI configuration, releases will keep tracking GitHub Actions deprecations — the notes already cite the Node.js 20 removal date. The four-year gap suggests updates arrive when something breaks rather than on a schedule.
q2
7.5INFRA · APIS
Two surfaces the original Quarto never had: llms.txt output and a live-share preview.
◆ Current state
q2 is the Quarto team's Rust reimplementation, shipping as a statically linked single binary with signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence has held at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. Until v0.22.0 the programme read as pure parity work against the existing Quarto — investigate, record design decisions, write tests red, implement in numbered phases. That release is the first to ship capability the original toolchain does not have.
◆ Where it's heading
The parity grind continues underneath — toc-location, add_html_dependency versioning, execute-visibility across both engines — but two strands now point past it. website.llms-txt makes a rendered site emit a machine-readable representation of itself: an llms.txt index, per-page .md companions, and a concatenated llms-full.txt, dogfooded on q2's own docs. The second is a long-running preview branch (PR #464, merged here) that turns q2 preview into a live-share editor with joinable guest sessions over an n0 relay and ephemeral, read-only-by-default boots. A reimplementation that only reaches parity has no argument for itself; these two give it one.
◆ Prediction
Expect the llms-txt and live-share strands to keep absorbing releases now that both have landed end-to-end, with the remaining Q1 parity items filling the gaps. The commit logs still name npx distribution for the standalone MCP bundle as the one explicitly planned item.
