rmarkdown vs SiYuan

rmarkdown vs SiYuan: at a glance
What is rmarkdown?
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.
What is SiYuan?
SiYuan's 3.8 line is eight builds deep and still stabilizing the same four features
SiYuan opened the 3.8.0 line on August 4 with four features it had not shipped before — an AI agent, semantic search over embeddings with reranking, Model Context Protocol support, and OIDC authentication. Every build since has restated that identical feature block while the enhancement list underneath it grows. The line crossed from alpha to beta on August 8 and has produced four betas in three days.

rmarkdown's job now is absorbing Pandoc's deprecations before users see them.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.

SiYuan's 3.8 line is eight builds deep and still stabilizing the same four features
◆ Current state
SiYuan opened the 3.8.0 line on August 4 with four features it had not shipped before — an AI agent, semantic search over embeddings with reranking, Model Context Protocol support, and OIDC authentication. Every build since has restated that identical feature block while the enhancement list underneath it grows. The line crossed from alpha to beta on August 8 and has produced four betas in three days.
◆ Where it's heading
The feature header has not changed across eight builds, so the work is stabilization, not expansion. What moves is the enhancement tail: LAN peer-assisted sync acceleration, audio recording on Android and HarmonyOS, S Pen hover on Android tablets, Rosetta detection for Intel builds. Read together, the release cadence is a desktop-first notes tool doing serious mobile and cross-platform catch-up while it lands its AI surface.
◆ Prediction
A stable 3.8.0 looks close given the beta cadence and the fact that no new features have entered the block since the line opened. The unresolved question these entries do not answer is where the AI agent and semantic search run — whether embeddings are computed locally or against a hosted service is never stated.
