Desktop sign release notes
Per-version notes for the desktop sign — the Electron application that runs on each kiosk and renders content.
How to read entries
Each release entry calls out four things:
| Field | What it tells you |
|---|---|
| Backend wire-compat | The range of backend versions this desktop sign tag works against. The backend is wire-compatible with at least the previous two desktop minors, so this is usually "anything current." |
| Image rebuild required | Whether the captured Windows image needs to be regenerated to pick up this release. Most patch releases don't; some minor releases do. |
| Operator-facing changes | Anything that changes what techs / event managers see on the dashboard or in the field. |
| Breaking changes | Anything that breaks an existing workflow. Rare; called out prominently when it happens. |
Versioning
Semantic versioning. The major.minor.patch convention:
- Major — incompatible changes, requires deliberate migration. Very rare.
- Minor — new features, possible image rebuild, backward-compatible.
- Patch — bug fixes, no rebuild required, drop-in safe.
Production tag freezes
The desktop sign has a production tag that does not move during active event windows. Backend deploys remain wire-compatible with at least the previous two desktop minors, so the backend can keep shipping while production kiosks stay frozen.
See Stability over features → Production tag freezes during events for the operational practice.
Update channels
| Channel | Used for | Update cadence |
|---|---|---|
| Production | Live events, deployed fleets | Manual via Check for Updates or image rebuild; never auto-applied during events |
| Staging | Pre-event testing, dogfooding | Tag-driven (desktop-vX.Y.Z-staging) |
Both channels distribute via updates.displaysync.live (Cloudflare R2) — same hosting, different prefixes.
Releases
Public release notes will be published here once tagged versions ship.
- Production tag in your fleet: check the Sign detail → Device info → App version field on any sign in the dashboard, or the Status Dashboard overlay (
Ctrl+Shift+S) on a kiosk.
