What is CoScreen?

CoScreen ships region sharing and macOS Tahoe support, but the release cadence has slowed to a handful of updates a year.

CoScreen is a remote-work screen-sharing tool that shares individual application windows rather than a full desktop. The last 14 months of visible signal cover three substantive releases — V8.10 (region sharing, macOS Tahoe), V8.2 (remote window top bar, focus mode), V8.1 (video layouts) — and a pair of V7.10 bug-fix follow-ups, plus a one-off enterprise access patch.

What is SiYuan?

SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform

SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.

CoScreen ships region sharing and macOS Tahoe support, but the release cadence has slowed to a handful of updates a year.

◆ Current state

CoScreen is a remote-work screen-sharing tool that shares individual application windows rather than a full desktop. The last 14 months of visible signal cover three substantive releases — V8.10 (region sharing, macOS Tahoe), V8.2 (remote window top bar, focus mode), V8.1 (video layouts) — and a pair of V7.10 bug-fix follow-ups, plus a one-off enterprise access patch.

◆ Where it's heading

Pace has slowed and each release stays close to the existing value prop — multi-window sharing — rather than pushing into adjacent collaboration territory. Region sharing is the most user-visible capability addition in the window, and macOS Tahoe support is reactive plumbing. The product reads as stewardship-mode, with occasional small feature drops, not a platform on a steep build curve.

◆ Prediction

At this cadence the next release likely arrives by late 2026 and skews toward platform parity, attention-management ergonomics, or bug fixes rather than a new capability surface. Anything more directional would require fresher signal than is currently in view.

SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform

◆ Current state

SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.

◆ Where it's heading

The headline direction is extensibility and automation: a plugin-capable kernel, CLI access, and secrets/variables move SiYuan from a self-contained app toward something developers can script and integrate. The breaking kernel API changes and the new serve subcommand are the cost of that platform shift. Underneath, steady editor/database hardening and broad localization continue.

◆ Prediction

Expect 3.7.0 to ship from the beta line with the plugin system and CLI as its banner features, followed by an ecosystem period of plugins and integrations building on the new kernel APIs. The repeated dev-build entries don't add direction beyond this.
