Castellum v0.2.1 — fixes Gmail sign-in.

Fixed

  • 🔑 Gmail login now completes. The token exchange failed with "client_secret is missing"; Castellum now includes the Google Desktop client secret (the standard, Google-sanctioned approach for desktop apps — PKCE protects the flow and your tokens stay encrypted in the macOS Keychain).

Note for Gmail

If you see "Access blocked: … developer-approved testers", the app's Google consent screen is in testing mode — the developer must add your address as a test user. Outlook/iCloud/Fastmail and any IMAP account work without this.

Download

  • Castellum-arm64.dmg — macOS 12+, Apple Silicon. Signed + notarized. Verify with Castellum-0.2.1-SHA256SUMS.txt.
  • Already on v0.2.0+? It will auto-update. Otherwise download once; updates are automatic after.
