ownCloud vs SiYuan: at a glance
What is ownCloud?
After years on the 10.x maintenance line, ownCloud Classic is finally cutting 11.0.0 candidates
Two tracks run side by side. The 10.16.x line continues as maintenance, with 10.16.4 published as a security release and upgrade strongly recommended for all installations. In parallel, ownCloud Server 11.0.0 has reached its third release candidate, with rc2 and rc3 consisting of version-string bumps and no code change.
What is SiYuan?
SiYuan is shipping eight 3.8.4 alphas in a week, adding AI agent DB control and mobile parity.
SiYuan is an open-source, self-hostable block-based PKM on a rapid alpha cadence. Eight 3.8.4 alphas shipped in under a week, building on the 3.8.3-beta.1 foundation that added remote kernel support and tabbed container blocks. The current release surface now includes AI agent control over database schema, mobile PDF annotation, document pinning, and configurable workspace appearance.

After years on the 10.x maintenance line, ownCloud Classic is finally cutting 11.0.0 candidates
◆ Current state
Two tracks run side by side. The 10.16.x line continues as maintenance, with 10.16.4 published as a security release and upgrade strongly recommended for all installations. In parallel, ownCloud Server 11.0.0 has reached its third release candidate, with rc2 and rc3 consisting of version-string bumps and no code change.
◆ Where it's heading
The interesting movement is the 11.0.0 candidate train — the first major-version step for Classic after a long run of 10.x point releases. The release notes attached to the candidates say nothing about capability, so what 11.0.0 actually changes for administrators is not yet visible here; the tags only show it converging.
◆ Prediction
A general 11.0.0 release is the obvious next step once the candidate train stops iterating, with the 10.16.x line likely continuing to receive security backports alongside it.
SiYuan
5.0COLLAB
SiYuan is shipping eight 3.8.4 alphas in a week, adding AI agent DB control and mobile parity.
◆ Current state
SiYuan is an open-source, self-hostable block-based PKM on a rapid alpha cadence. Eight 3.8.4 alphas shipped in under a week, building on the 3.8.3-beta.1 foundation that added remote kernel support and tabbed container blocks. The current release surface now includes AI agent control over database schema, mobile PDF annotation, document pinning, and configurable workspace appearance.
◆ Where it's heading
Two architectural moves define this cycle: an AI-agent-first data layer — where the agent can now configure database fields, not just query them — and a remote-kernel execution model separating the SiYuan kernel from the frontend. Mobile parity is the sustained third push, with iPadOS 26 compatibility, mobile-specific database bottom sheets, and PDF annotation on mobile all landing across this alpha train.
◆ Prediction
A 3.8.4 beta should land within days given the alpha pace; expect it to consolidate AI agent database integration and the remote kernel GUI as headline features. The next directional capability surface is not visible in these entries.
