SiYuan
SiYuan's 3.8 line is eight builds deep and still stabilizing the same four features
A side-by-side editorial comparison of Read the Docs and rmarkdown — release velocity, themes, recent moves, and the top alternatives to consider.
Read the Docs is rebuilding its build farm around uv and isolated builders, one week at a time.
Weekly date-tagged releases, almost entirely build infrastructure. The visible work is a migration to uv-managed environments and isolated, ephemeral builders, shipped in small increments between routine dependency bumps. The most recent release is plumbing: skip build status when there is no commit, pin pip back, and point uv at the interpreter inside the venv.
rmarkdown's job now is absorbing Pandoc's deprecations before users see them.
rmarkdown is at 2.31. Its releases read as a compatibility layer: switching to --syntax-highlighting for Pandoc 3.8 because --highlight-style is deprecated, dropping a syntax-highlighting workaround made unnecessary by Pandoc 2.18 three years ago, restoring table row classes that a Pandoc change removed, and falling back to html_document when a YAML output format is unrecognised.

The most recent release is plumbing: skip build status when there is no commit, pin pip back, and point uv at the interpreter inside the venv.
The isolated builder is the arc worth tracking — private repository support, an ephemeral builder script, and removal of the old scale-in protection path all point at builds that run in disposable environments. User-facing change is rare and arrives as a side effect, as when July's release moved images to Ubuntu 26.04 and Python 3.14.
Expect the isolated builder to become the default path and further uv environment fixes; feature work should stay secondary until that migration finishes.
rmarkdown is at 2.31.

The package is stable and mostly defensive. Each release absorbs a change in Pandoc or knitr so documents keep rendering, with the occasional user-facing escape hatch — the rmarkdown.files.suffix option exists because the default _files directory made cloud sync tools delete HTML output. Little here extends what an R Markdown document can do; it keeps existing ones working.
Given that the last two releases both handled Pandoc 3.8 flag deprecations, the next is likely to track further Pandoc changes rather than add an output format.
