Pydio Cells vs SiYuan: at a glance
What is Pydio Cells?
Cells v5 rebuilt content and metadata, and the two releases since have gone straight into sync repair
Cells v5 landed in late May with a new Pages display, a custom metadata system rebuilt around an Entity Values store, and reworked microservices for clustered deployments. The two releases since are maintenance: sync engine fixes covering partial sync, event ordering, metadata propagation and goroutine lifecycles, iOS client compatibility restored, plus server-to-server sync diff handling and Helm and Docker packaging cleanups.
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.

Cells v5 rebuilt content and metadata, and the two releases since have gone straight into sync repair
◆ Current state
Cells v5 landed in late May with a new Pages display, a custom metadata system rebuilt around an Entity Values store, and reworked microservices for clustered deployments. The two releases since are maintenance: sync engine fixes covering partial sync, event ordering, metadata propagation and goroutine lifecycles, iOS client compatibility restored, plus server-to-server sync diff handling and Helm and Docker packaging cleanups.
◆ Where it's heading
The shape is a large platform release followed by a stabilisation tail concentrated almost entirely on the sync engine — both maintenance releases name sync reliability first. For a file platform that is the load-bearing subsystem, so this is the expected cost of touching every layer at once, not a detour.
◆ Prediction
Expect further stable-branch maintenance focused on sync and clustered deployment before feature work resumes on the v5 line.

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.
