dsh-update-check

DSH ships on two independent update tracks — the official desktop build distributed via dshdesktop.cn and the GitHub source at deepseek-ai/deepseek-harness — and keeping both current normally means opening a browser, comparing version numbers, downloading an installer, and restarting the app by hand. dsh-update-check collapses both channels into a single status capsule at the top of every session. Its first check fires five seconds after launch, then polls on a configurable interval (12 hours by default) with a quiet one-hour retry on transient failure, so you always know your update status without leaving the editor.

The desktop channel talks to the official version endpoint and CDN installer on dshdesktop.cn. When a newer build is detected the capsule lights up with an upward arrow; clicking Download and Update in the panel kicks off the roughly 160 MB download, relaunches the NSIS installer with the same --updated --force-run flags the official flow uses, hands control to the installer, and auto-restarts once it finishes — zero manual steps in between. The source channel cascades through the REST API, an Atom feed, and a master-branch version fallback so a GitHub rate limit never breaks detection, and can pull the latest codeload zip on demand or display the release changelog right in the panel.

It is built for two audiences: everyday DSH Desktop users who want a tap-to-update experience with no browser tab involved, and developers tracking the source repository who need an at-a-glance signal of whether their local build is behind the latest release without context-switching. State is persisted to ~/.dsh, sessions and configuration are untouched by the update process, and the installer binary is the one served from the official channel — the plugin performs no binary modification whatsoever.
