Changelog

All notable changes to the Velxio Simulator VS Code extension are documented here.

0.2.0

A Velxio Pro subscription is now required to compile or run a sketch from inside VS Code. A free 30-day trial is included and starts the first time you sign in. Anonymous compile/run is no longer supported — the extension is gated against the license backend on every command.

Velxio: Sign In command — opens https://velxio.dev/auth/vscode in your browser. After signing in (or creating an account), the page hands a license token back to VS Code via the vscode://velxio.velxio-simulator/auth URI scheme.
Velxio: Paste License Key command — alternative for headless setups or shared machines. Keys live in ExtensionContext.secrets (OS keychain), never in settings.json.
Velxio: Sign Out command — clears the stored key.
Velxio: Show License Status command — displays the current plan, trial countdown, and renewal date.
Status bar item next to the board picker shows the current license state: Velxio: Sign in, Velxio: Trial Nd, Velxio: Pro, or Velxio: Trial ended (with the status bar warning/error background colour applied automatically).
New setting velxio.licenseApiBase (default https://velxio.dev) for staging/dev overrides. Leave at the default for production.

New LicenseService (src/LicenseService.ts) encapsulates secret storage, the deep-link nonce flow, validation against /api/pro/license/validate, and a 60-second in-memory cache so a tight compile/run loop doesn't hammer the endpoint.
The extension is online-only by design — validation throws on network failure rather than caching a permission grant locally.

Self-hosted Velxio backends do not expose /api/pro/license/*. The VS Code extension is a velxio.dev product and validates exclusively against https://velxio.dev. Override velxio.licenseApiBase only if you are a Velxio developer testing against staging.

Initial release. Compile + simulate Arduino / RP2040 / ESP32 sketches locally from inside VS Code, no auth required.
