BookStack vs SiYuan: at a glance
What is BookStack?
BookStack's release log is now mostly security patches between feature drops.
BookStack ships a feature release roughly every four months and fills the gaps with point releases that are almost all security fixes. The latest feature release, v26.09, added a customizable interface layout system and scoped search API endpoints; every point release since has closed permission and visibility holes.
What is SiYuan?
SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.
SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.
BookStack vs SiYuan: editorial side-by-side
BookStack
5.0COLLAB
BookStack's release log is now mostly security patches between feature drops.
◆ Current state
BookStack ships a feature release roughly every four months and fills the gaps with point releases that are almost all security fixes. The latest feature release, v26.09, added a customizable interface layout system and scoped search API endpoints; every point release since has closed permission and visibility holes.
◆ Where it's heading
The recurring vulnerability theme is permission edge cases around drafts, the recycle bin and attachments, which suggests a steady external research effort probing the permission model. Feature work is leaning toward customization and API reach while the security cadence keeps the core trustworthy for self-hosters.
◆ Prediction
Expect at least one more security point release before the next feature version, likely again touching drafts, attachments or recycle-bin permissions, since those areas recur in nearly every patch.
SiYuan
5.0COLLAB
SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.
◆ Current state
SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.
◆ Where it's heading
SiYuan works in fast public cycles, with the next version's alphas starting as soon as the last one stabilises. 3.8.11 is about polish and editing depth: mind maps, databases and the new Markdown editor all get more control.
◆ Prediction
Expect more 3.8.11 alphas, then betas and release candidates with the same list, following the 3.8.10 pattern.
