DcDNS v1.0.3

What's New

  • Dual Mullvad DNS Resolver: Added a fallback DoH resolver (adblock.dns.mullvad.net) alongside the primary (dns.mullvad.net). If the primary resolver is unavailable, Discord automatically switches to the fallback without silently downgrading to plain DNS. Both resolvers operate in strict DoH mode.
  • Updated Chromium DNS Feature Flag: The enable-features flag now passes both DoH endpoints directly to the Electron engine.

Privacy & Security

  • Updated the Policy Framework text to clearly list both the Primary and Fallback Mullvad resolvers.
  • Strengthened the DNS policy configuration to support multiple secure servers via app.configureHostResolver().

UX & Interface

  • Replaced the automatic browser popup on startup with a manual "Join Our Discord" button in the Policy Agreement screen. The application now launches cleanly without opening external links automatically.
  • Removed open_startup_links() from the startup flow.

Technical

  • DCDNS_DOH_SERVERS array updated to include both Mullvad endpoints.
  • POLICY_TEXT revised for clarity on DNS behavior and backup procedures.

Note: Discord auto-updates overwrite the patched index.js. After any Discord update, re-run DcDNS and click Install to re-apply the patch.
