Read the Docs vs SiYuan: at a glance
What is Read the Docs?
Read the Docs ships a dated release every week, and this one is documentation and dependencies
Read the Docs cuts a date-versioned release most weeks, each a generated list of merged pull requests. Recent substance has been in two areas: the GitHub App integration, where rate-limit handling stopped deleting repositories and commit-status errors no longer raise spurious notifications, and the build environment, where isolated builders gained private-repo support and uv-based installs. Around that, a steady flow of dependency bumps and documentation edits.
What is SiYuan?
SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.
SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

Read the Docs ships a dated release every week, and this one is documentation and dependencies
◆ Current state
Read the Docs cuts a date-versioned release most weeks, each a generated list of merged pull requests. Recent substance has been in two areas: the GitHub App integration, where rate-limit handling stopped deleting repositories and commit-status errors no longer raise spurious notifications, and the build environment, where isolated builders gained private-repo support and uv-based installs. Around that, a steady flow of dependency bumps and documentation edits.
◆ Where it's heading
The GitHub App work is the thread worth watching — the project is hardening the path where it syncs a user's repositories, and the fixes have been about failing safely when GitHub throttles rather than about new capability. Build tooling continues to move toward uv. On the documentation side, the supported-tools list keeps widening, with Starlight added and Zensical's introduction reworked, which tracks the platform's shift away from being Sphinx-shaped.
◆ Prediction
Documentation keeps naming new generators before the platform's own tooling catches up to them, so expect build-side support work for the non-Sphinx generators the docs now list.
SiYuan
5.0COLLAB
SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.
◆ Current state
SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.
◆ Where it's heading
The 3.8.x line keeps turning databases and mind maps into structured tools that act on the block graph, and the built-in agent is gaining reach into document content such as PDFs. The release cadence is fast and noisy, with most builds repeating the same cumulative notes.
◆ Prediction
A stable 3.8.9 is likely within days, with little added beyond fixes now that it has reached RC.
