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 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

Pydio Cells vs SiYuan: editorial side-by-side

P0.0

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.

5.0

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

◆ Current state

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

◆ Where it's heading

The 3.8.x line keeps turning databases and mind maps into structured tools that act on the block graph, and the built-in agent is gaining reach into document content such as PDFs. The release cadence is fast and noisy, with most builds repeating the same cumulative notes.

◆ Prediction

A stable 3.8.9 is likely within days, with little added beyond fixes now that it has reached RC.
