What is CoScreen?

CoScreen ships its final build and declares End of Life after a year of quiet.

CoScreen just shipped V8.11.14, explicitly labeled its final software update, alongside an official End of Life announcement. The last real feature release was V8.10 in August 2025 (screen-region sharing plus macOS Tahoe support); the eleven months since produced nothing but this shutdown notice. The multiplayer, multi-window screen-sharing tool for remote teams is being retired rather than iterated.

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.

CoScreen vs SiYuan: editorial side-by-side

3.8

CoScreen ships its final build and declares End of Life after a year of quiet.

◆ Current state

CoScreen just shipped V8.11.14, explicitly labeled its final software update, alongside an official End of Life announcement. The last real feature release was V8.10 in August 2025 (screen-region sharing plus macOS Tahoe support); the eleven months since produced nothing but this shutdown notice. The multiplayer, multi-window screen-sharing tool for remote teams is being retired rather than iterated.

◆ Where it's heading

The cadence tells the story: steady usability and performance work through 2024 and into early 2025, a last genuine feature drop in August 2025, then silence until today's EOL. This is a sunset, not a pivot. Users can expect the app to keep running on 8.11.14 but to receive no further fixes or OS-compatibility updates.

◆ Prediction

With EOL declared and a final build shipped, the only moves left are wind-down mechanics: a hard shutdown date, export or migration guidance, and eventual removal from distribution. No further feature work is coming.

6.3

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.
