What is SiYuan?
SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.
What is Tango?
Tango is dual-tracking workflow documentation and a browser-based AI CRM agent.
Tango's core surface — capturing browser workflows into step-by-step guides — keeps gaining depth: voice transcription during capture, workflow branching for multiple paths, translations for global teams, video embeds, and governance and compliance views for Enterprise. In parallel, Tango bet hard a year ago on browser-based AI agents with the AI CRM Admin, aimed at sales and revops teams who otherwise spend hours on repetitive Salesforce-style updates. Both bets are still being shipped against, but the cadence on the documentation side is markedly higher.

SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
◆ Current state
SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.
◆ Where it's heading
This is consolidation of the surface 3.8.0 opened, not an extension of it. The agent, semantic search and MCP endpoint arrived in the 3.8.0 line; 3.8.1 makes them portable and pluggable - skills come from a directory the user controls, editor actions follow the user between devices, and the provider layer now speaks the OpenAI Responses API rather than one bespoke shape. The high beta count against a modest final diff shows a project stabilising a young subsystem rather than building a new one.
◆ Prediction
The next line most likely pushes on the skills directory - discovery, sharing or marketplace distribution of user-level skills - since that is the piece 3.8.1 made user-editable without giving it a distribution path.
Tango
1.3COLLAB
Tango is dual-tracking workflow documentation and a browser-based AI CRM agent.
◆ Current state
Tango's core surface — capturing browser workflows into step-by-step guides — keeps gaining depth: voice transcription during capture, workflow branching for multiple paths, translations for global teams, video embeds, and governance and compliance views for Enterprise. In parallel, Tango bet hard a year ago on browser-based AI agents with the AI CRM Admin, aimed at sales and revops teams who otherwise spend hours on repetitive Salesforce-style updates. Both bets are still being shipped against, but the cadence on the documentation side is markedly higher.
◆ Where it's heading
Tango is making documentation deeper and more multilingual while incubating a separate AI-agent product line on top. The implicit thesis is that workflow capture is the moat — anyone can build a CRM agent, but capturing the exact path a human takes and translating it into agent actions is harder. The two surfaces should eventually converge, but right now they look more like a mature product plus a bet than a unified strategy.
◆ Prediction
Expect AI CRM Admin to gain second-system breadth (HubSpot, Outreach, or other revops surfaces beyond Salesforce) and the documentation side to start exposing captures as agent-runnable workflows — using the existing capture data as the substrate for autonomous execution.
