What is SiYuan?
SiYuan's v3.7.0 cycle adds a kernel plugin system, CLI, and secrets config to the local-first notebook
SiYuan is deep in its v3.7.0 pre-release cycle, and the feed is a long run of beta, dev, and rc builds that all carry the same changelog. The headline additions are a kernel plugin system, a command-line interface, configurable secrets and variables, a rebuilt settings UI, and a new default theme and icon, alongside a breaking change requiring an explicit serve subcommand.
What is Outline?
Outline is steadily polishing its wiki while quietly opening up to AI assistants via MCP.
Outline ships at a measured cadence focused on editor and collaboration polish: task-list and table refinements, request-access flows, public document subscriptions, and passkeys. The standout thread is a meaningfully expanded MCP server that lets AI assistants patch, move, and delete documents and manage inline comments, plus integrations like GitLab and Draw.io.

SiYuan's v3.7.0 cycle adds a kernel plugin system, CLI, and secrets config to the local-first notebook
◆ Current state
SiYuan is deep in its v3.7.0 pre-release cycle, and the feed is a long run of beta, dev, and rc builds that all carry the same changelog. The headline additions are a kernel plugin system, a command-line interface, configurable secrets and variables, a rebuilt settings UI, and a new default theme and icon, alongside a breaking change requiring an explicit serve subcommand.
◆ Where it's heading
v3.7.0 is the most extensibility-focused release in a while: a plugin system and CLI turn the kernel from a fixed app into something scriptable and extendable, while secrets/variables and Safe Mode point at more serious self-hosted and automation use. The breaking serve subcommand signals the team is willing to tidy the kernel's command surface to support this. Otherwise the release is dense with the usual editor and sync reliability fixes.
◆ Prediction
Expect v3.7.0 to ship from rc to stable soon given the cadence, after which plugin-system documentation and third-party kernel plugins are the natural next thread.
Outline
5.0COLLAB
Outline is steadily polishing its wiki while quietly opening up to AI assistants via MCP.
◆ Current state
Outline ships at a measured cadence focused on editor and collaboration polish: task-list and table refinements, request-access flows, public document subscriptions, and passkeys. The standout thread is a meaningfully expanded MCP server that lets AI assistants patch, move, and delete documents and manage inline comments, plus integrations like GitLab and Draw.io.
◆ Where it's heading
The core product is mature and evolving incrementally, but the MCP investment points to Outline positioning itself as an AI-operable knowledge base rather than just a human wiki. Collaboration features like access requests and subscriptions suggest a push toward broader, less-managed readership.
◆ Prediction
Expect continued incremental editor improvements alongside a deeper MCP surface, making Outline a knowledge source that external AI agents can both read and edit.
