SLmetrics
A young ML metrics package rewrote its own backend twice in six months chasing speed.
A side-by-side editorial comparison of plogr and q2 — release velocity, themes, recent moves, and the top alternatives to consider.
A logging header for Rcpp packages that sat untouched for nine years, then changed how it switches on
plogr ships a stripped build of the plog C++ logging library as an R package, so other packages with C++ code can log through REprintf() and have output land in the R console rather than stdout. It is a header-only dependency with no R-level API to speak of. Three releases in September 2016 established it; the next arrived in November 2025.
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.

There is almost no trajectory to read here, which is itself the finding — the package was finished in a week and stayed finished. The 2025 release is the first change in nine years and it tightens the activation contract: logging now does nothing unless PLOGR_ENABLE is defined at compile time, so packages depending on it get silence by default rather than unexpected output. A GCC-specific fix for function names in multi-argument template classes lands alongside.
With the activation macro now explicit, dependent packages that assumed logging was on will need to define it; beyond that the entries give no basis for expecting further development.

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.
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.
