SiYuan rides its 3.7 overhaul with rapid alpha polish on mobile and cross-platform

◆ Current state

SiYuan is an open-source, local-first knowledge base. Its 3.7 line was a throughout renewal — a redesigned UI, a kernel plugin system, and a CLI — and the feed since has been a fast cadence of alpha releases (3.7.1, 3.7.2) grinding on mobile editing and cross-platform quirks across Android, HarmonyOS, iOS, and the Microsoft Store build.

◆ Where it's heading

The work is consolidating the 3.7 overhaul along three lines: extensibility (kernel plugins), cross-platform parity (HarmonyOS now treated as a first-class target alongside Android and iOS), and mobile editing polish. The 'step toward intelligence' language hints at AI features, but the concrete shipping is platform breadth and extensibility.

◆ Prediction

Expect 3.7.2 to stabilize out of alpha with continued mobile and HarmonyOS fixes; the kernel plugin system points toward a growing third-party plugin ecosystem as the next surface.

D6.3

Document360 is rebuilding the knowledge base around AI agents — readable by them and operable through them.

◆ Current state

Document360 is a knowledge-base and documentation platform shipping monthly point releases. The recent arc is heavily AI-shaped: an MCP server connects ChatGPT, Claude, and Copilot to the KB, then expands to manage the full content lifecycle — search, create, update, assign reviewers, and publish — from inside an AI assistant. The June release adds auto-generated llms.txt so AI agents can discover and cite docs accurately, plus native Mermaid diagrams. Enterprise plumbing (SCIM, multiple JWT configs, CSP controls) rounds out the cadence.

◆ Where it's heading

The product is positioning the knowledge base for the AI-agent era on two fronts: making docs machine-readable and citable (llms.txt, MCP search), and making content operations agent-driven (publish/workflow via MCP). Around that core bet, Document360 keeps hardening multilingual, security, and analytics for enterprise buyers.

◆ Prediction

Expect continued deepening of the MCP and AI-discoverability surface — more lifecycle actions exposed to assistants and richer agent analytics — alongside the steady enterprise security and localization work.
