Nextcloud vs SiYuan: at a glance
What is Nextcloud?
Nextcloud ships three patch lines in a day as 35.0.2 adds webhook metadata and a report API.
Nextcloud released 35.0.2, 34.0.5 and 33.0.10 on the same day, a month after the 35.0.0 major that swapped OnlyOffice for Euro-Office and added FrankenPHP support. The backports share a security-flavored core: a CSRF token on the share-accept endpoint, upload checks against session and share tokens, and logs that no longer leak sensitive data. 35.0.2 also adds richer node-webhook metadata, webhook-compatible comment events and an API for system-report sections.
What is SiYuan?
SiYuan opens 3.8.10 with long-term AI memory and database sub-items.
SiYuan opened the 3.8.10 line with alpha.1 on Oct 31, three days after 3.8.9 reached RC. The alpha lists 16 items, including workspace-level long-term memory for AI, database sub-items, HTTP requests in templates, an Exa API key option for built-in web search and custom PDF page sizes. No stable 3.8.9 appears in the feed, so rc.1 is the last visible milestone for that line.

Nextcloud
6.3COLLAB
Nextcloud ships three patch lines in a day as 35.0.2 adds webhook metadata and a report API.
◆ Current state
Nextcloud released 35.0.2, 34.0.5 and 33.0.10 on the same day, a month after the 35.0.0 major that swapped OnlyOffice for Euro-Office and added FrankenPHP support. The backports share a security-flavored core: a CSRF token on the share-accept endpoint, upload checks against session and share tokens, and logs that no longer leak sensitive data. 35.0.2 also adds richer node-webhook metadata, webhook-compatible comment events and an API for system-report sections.
◆ Where it's heading
The patch stream is still dominated by sharing permissions, resharer caps and encryption cache fixes, now applied across three supported branches at once. The small additions in 35.0.2, webhooks and the 'Unified Sharing Legacy Sync' groundwork, point to sharing being rebuilt under the hood and to more automation hooks for integrators. The 35 line is absorbing regressions from the major at a steady monthly pace.
◆ Prediction
Expect a 35.0.3 within a month continuing sharing and encryption fixes, with more of the unified-sharing work surfacing; the entries do not say when that rework becomes user-visible.
SiYuan
5.0COLLAB
SiYuan opens 3.8.10 with long-term AI memory and database sub-items.
◆ Current state
SiYuan opened the 3.8.10 line with alpha.1 on Oct 31, three days after 3.8.9 reached RC. The alpha lists 16 items, including workspace-level long-term memory for AI, database sub-items, HTTP requests in templates, an Exa API key option for built-in web search and custom PDF page sizes. No stable 3.8.9 appears in the feed, so rc.1 is the last visible milestone for that line.
◆ Where it's heading
The built-in agent keeps gaining context: image extraction from PDFs in 3.8.9, then workspace memory and configurable web search in 3.8.10. Databases keep moving toward structured tooling, with sub-items following block-reference automation, and templates can now reach outside the workspace over HTTP. The release cadence stays fast and noisy, with cumulative notes often repeated across builds.
◆ Prediction
More 3.8.10 alphas are likely within days, given the pace of the 3.8.9 series. When a stable 3.8.9 lands is unclear from the entries.
