SiYuan
SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.
A side-by-side editorial comparison of Memos and Wiki.js — release velocity, themes, recent moves, and the top alternatives to consider.
Memos adds collaborative Spaces without handing administrators the keys to everyone's notes.
Memos is a self-hosted memo archive that has spent three release candidates rebuilding its foundations rather than its surface. 0.27 embedded an MCP server in the instance, 0.30 flipped undeclared instances to private mode and regenerated that MCP surface from the OpenAPI schema, and 0.31.0-rc.1 now introduces first-class Spaces with ADMIN and USER memberships. The ownership model was rewritten alongside it: instance administrators are no longer implicit collaborators on other people's memos.
Wiki.js 3.0 beta ships an MCP server so AI agents can work against the wiki directly.
Wiki.js 3.0 is still a beta not meant for production, but beta.705 adds a built-in MCP server, refined personal access token scopes, page lifecycle rules with page ownership, a feedback board where reviewers manage ideas, and link completion in the markdown editor. Recent betas added live notes, math, access tokens, SCIM and Excalidraw collaboration.

The direction runs from one person's notebook toward shared, agent-addressable infrastructure, and the order matters — access control and a stable API surface landed before multi-user sharing did. Each candidate has carried its breaking changes rather than deferring them: Shortcuts became Saved Views across the API, MCP tools and web routes, reactions lost content_id, S3 attachments stopped returning presigned URLs, and the Explore and per-user RSS feeds now return 404. Memos is willing to spend client compatibility to keep the data model coherent.
Expect 0.31 to reach a stable release with migration guidance for the Saved Views rename, and for Space scoping to extend next to the surfaces the notes say stay global — Archived, Inbox, profiles and Settings.

Recent betas added live notes, math, access tokens, SCIM and Excalidraw collaboration.
Each beta adds a piece that larger teams need: SSO and SCIM, governance through ownership and lifecycle rules, and now machine access through MCP and scoped tokens. 3.0 is becoming an AI-accessible knowledge base with enterprise controls rather than a straight successor to 2.x.
Expect MCP tools to be tied to the new PAT scopes and page rules, and the beta cadence to keep adding governance features before a release candidate.
