What is Outline?
Outline gave AI assistants write access to the wiki, then spent months on the human side.
The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.
What is SiYuan?
SiYuan's v3.8.0 train restates one AI feature set across seven consecutive builds.
SiYuan is deep in a v3.8.0 preview train — four alphas and three betas since August 1 — and every build republishes the same four headline features: an AI Agent, semantic search over AI embeddings with reranking, Model Context Protocol support, and OIDC authentication. Two pairs of these builds carry byte-identical published notes, so the per-build delta is not visible from the feed at all. What does vary is a long enhancement list covering sync, mobile platforms and database views.

Outline

Outline gave AI assistants write access to the wiki, then spent months on the human side.
◆ Current state
The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.
◆ Where it's heading
Two audiences are being served in sequence. The MCP work moved assistants from reading the knowledge base to editing it, including the collection structure itself. The releases after it close ordinary gaps in how people find, follow and get into documents — which is what a wiki needs before more of its edits arrive from automation. Release cadence is roughly monthly with entries that describe outcomes rather than changelogs.
◆ Prediction
Expect the human-facing polish to continue at its current pace, with any next structural move likely extending the MCP surface further into permissions and collection management, since that is where the existing tools stop.
SiYuan
6.3COLLAB
SiYuan's v3.8.0 train restates one AI feature set across seven consecutive builds.
◆ Current state
SiYuan is deep in a v3.8.0 preview train — four alphas and three betas since August 1 — and every build republishes the same four headline features: an AI Agent, semantic search over AI embeddings with reranking, Model Context Protocol support, and OIDC authentication. Two pairs of these builds carry byte-identical published notes, so the per-build delta is not visible from the feed at all. What does vary is a long enhancement list covering sync, mobile platforms and database views.
◆ Where it's heading
The release notes are cumulative rather than incremental, which makes the train read as a single release delivered in installments. Beneath the repeated feature banner the actual work is platform breadth: LAN peer-assisted acceleration for cloud sync, audio recording on Android and HarmonyOS, custom font import on mobile, and configurable Stable, Beta and Alpha update channels. Reaching beta.3 within ten days of the first alpha says the train is converging.
◆ Prediction
A v3.8.0 stable release looks close given the move from first alpha to third beta inside ten days. The update-channel setting arriving in this same cycle suggests the project intends to keep running parallel preview streams once it ships.
