HedgeDoc vs SiYuan: at a glance
What is HedgeDoc?
HedgeDoc 1.x releases are now mostly advisories — security in, features rarely.
The 1.x line ships on a roughly six-to-eight-week rhythm, and almost every release leads with security fixes: HTML injection through an email localpart, YAML frontmatter denial-of-service, CSRF in the Gist export, a rate-limit bypass via the CF-Connecting-IP header, SVG upload script execution. Around that, the recent additions are operator controls — an external-link warning page with a whitelist, configurable login and signup rate limits, an option to restrict uploads to registered users or disable them entirely.
What is SiYuan?
SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

HedgeDoc
2.5COLLAB
HedgeDoc 1.x releases are now mostly advisories — security in, features rarely.
◆ Current state
The 1.x line ships on a roughly six-to-eight-week rhythm, and almost every release leads with security fixes: HTML injection through an email localpart, YAML frontmatter denial-of-service, CSRF in the Gist export, a rate-limit bypass via the CF-Connecting-IP header, SVG upload script execution. Around that, the recent additions are operator controls — an external-link warning page with a whitelist, configurable login and signup rate limits, an option to restrict uploads to registered users or disable them entirely.
◆ Where it's heading
This reads as a mature collaborative editor in hardening mode. New settings appear where an administrator needed a lever, not where a user asked for a feature, and the one substantial correctness fix in the window — data loss when five or more people edited a document at once — was a repair to the existing operational-transform client rather than new ground. Node 24 support and the removal of dead config options point the same direction: keeping a working product current.
◆ Prediction
Expect the next 1.x release to follow the same shape — one or more advisories plus a small configuration option — since every release in this window has done so.
SiYuan
6.3COLLAB
SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
◆ Current state
SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.
◆ Where it's heading
This is consolidation of the surface 3.8.0 opened, not an extension of it. The agent, semantic search and MCP endpoint arrived in the 3.8.0 line; 3.8.1 makes them portable and pluggable - skills come from a directory the user controls, editor actions follow the user between devices, and the provider layer now speaks the OpenAI Responses API rather than one bespoke shape. The high beta count against a modest final diff shows a project stabilising a young subsystem rather than building a new one.
◆ Prediction
The next line most likely pushes on the skills directory - discovery, sharing or marketplace distribution of user-level skills - since that is the piece 3.8.1 made user-editable without giving it a distribution path.
