Read the Docs
Read the Docs is rebuilding its build farm around uv and isolated builders, one week at a time.
A side-by-side editorial comparison of Double and rmarkdown — release velocity, themes, recent moves, and the top alternatives to consider.
Double is moving the whole bookkeeping workflow into a chat assistant, one billable task per week.
Double ships weekly, and for two months straight nearly every release has been another accounting task absorbed into Ask Double: transactions in late June, live spreadsheets, AI workpapers, metrics creation, voice input, and now Connections to outside tools. The assistant has gone from answering questions about the books to creating the artifacts accountants bill for. The most recent entry breaks the pattern — role-based restrictions on who can edit client properties — which is the administrative counterweight to everything else.
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.
Double ships weekly, and for two months straight nearly every release has been another accounting task absorbed into Ask Double: transactions in late June, live spreadsheets, AI workpapers, metrics creation, voice input, and now Connections to outside tools. The assistant has gone from answering questions about the books to creating the artifacts accountants bill for. The most recent entry breaks the pattern — role-based restrictions on who can edit client properties — which is the administrative counterweight to everything else.
The strategy is to make Ask Double the primary interface and reduce the app's tab-by-tab surface to a system of record behind it. Two constraints are being addressed in parallel: the assistant needed to reach data Double does not hold, which Connections solves, and firms needed guardrails before handing an assistant this much reach, which the permissions work starts. Exposing metrics through both Ask Double and an MCP/API endpoint suggests Double expects agents outside its own product to drive the platform too.
Connections should exit private beta and expand its connector list, since it is the dependency for the cross-tool briefings Double is pitching. Expect the permissions model to keep hardening in step with each new thing the assistant is allowed to create.
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 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.
