DNSCrypt Proxy GUI 1.2.1

DNSCrypt Proxy GUI 1.2.1

Changed

• Removed the "Restore DNS" button. It performed exactly the same action as Deactivate while the proxy was running, and its only other use - repairing settings left behind by a crashed session - already happens automatically every time the app starts.

Nothing else changes: your DNS settings are still snapshotted before any activation and restored verbatim on deactivation or exit, and recovery after a crash remains fully automatic.

What's Changed

• Remove redundant Restore DNS button by @neohiro in #20

DNSCrypt Proxy GUI 1.2.0

New

• Update checker (Configuration tab, bottom row): a quiet version line with a Check for update button. The app also probes silently at startup - if a newer release exists, the version line lights up as a clickable link to the download page. Version comparison is true semver (component-wise), so 1.10.0 correctly ranks above 1.9.0; network failures never nag at startup.

Fixed

• Config changes during an active session now really restart the proxy. Previously "Changes are applied immediately" only wrote settings - the running proxy kept its old configuration until a manual deactivate/reactivate.
• A crashed tray icon no longer tears down your protection: the app degrades to taskbar mode instead of quitting, and closing then asks before exiting.
• Auto-reactivation race eliminated: starting the app could spawn two dnscrypt-proxy processes racing for port 53, leaving one that Deactivate could not stop. Reactivation is strictly once per session.
• Corrupted/mirrored resolver lists are handled safely: duplicate or nameless entries are dropped at ingestion instead of crashing the server table; hand-edited relay mappings in settings.json are ignored with a warning instead of raising errors.

For contributors

• New integration test drives the real GUI through activate → config-change-restart → deactivate against a stub proxy on every push (Linux CI under xvfb, both Python 3.11 and 3.12). 93 tests total.

What's Changed

• Fix: config changes during an active session never restarted the proxy by @neohiro in #18
• Update checker (semver) + restart-cycle integration test by @neohiro in #19

DNSCrypt Proxy GUI 1.1.0

DNSCrypt Proxy GUI 1.1.0

Robustness release covering everything landed since 1.0.5.

Fixed

• Tray crash no longer deactivates your proxy. If the system-tray thread failed, the app used to quit entirely - silently stopping a running proxy and reverting your DNS. It now logs the failure, switches to taskbar mode and keeps protecting you; closing the window then asks before exiting.
• Auto-reactivation race eliminated. When a resolver-list refresh completed faster than startup reactivation, a second activation attempt could spawn a second dnscrypt-proxy over the live one - leaving a proxy that the Deactivate button could not stop. Reactivation now happens exactly once per session.
• Corrupted or mirrored resolver lists can no longer break the app. Duplicate or nameless entries are dropped at both ingestion points (upstream fetch and local cache); previously a duplicate name crashed the server table with an internal error.
• Hand-edited settings are tolerated. A malformed relay mapping no longer crashes config generation, and listing the same relay twice produces one clean route instead of duplicated entries.
• Partial cache files load safely - older cache files missing newer fields no longer cause errors when populating the server list.

Hardened

• Run-at-startup registration is correct for every install type and handles paths with spaces/quotes/special characters on Windows, Linux and macOS.
• Single-instance detection is reliable; configuration restarts report "busy" instead of silently dropping changes.
• Partial DNS restores keep their backup for retry instead of falling back to a DHCP reset.
• More diagnostics in the log file for proxy-output and shutdown edge cases.

For contributors

• CI gates every PR and push: lint + tests + headless GUI smoke test on Python 3.11/3.12, with job timeouts; Dependabot tracks GitHub Actions versions.

What's Changed

• Production readiness: name dedupe, tray fallback, reactivation race by @neohiro in #16
• Ingestion tolerance: malformed relay maps, duplicate relays, partial caches by @neohiro in #17

Full Changelog: v1.0.5...v1.1.0

DNSCrypt Proxy GUI 1.0.5

DNSCrypt Proxy GUI 1.0.5

Fixed

• Linux/Wayland: app no longer crashes on startup. The system-tray backend could fail while importing on Wayland-only sessions or headless systems in a way the previous guard did not catch; any tray failure now degrades gracefully to running without a tray icon (closing minimises to the taskbar).

Hardened (since 1.0.4)

• Run-at-startup registration is now correct for every install type: frozen builds no longer register themselves twice, and paths containing spaces, quotes or % characters work in Windows Run keys, Linux .desktop entries and macOS launch agents.
• Single-instance detection is now reliable (Windows last-error handling hardened).
• Configuration restarts report "busy" instead of silently dropping changes when another operation is still running.
• Safer DNS restore policy: a partially failed restore keeps its backup for retry instead of falling back to a DHCP reset.

For contributors

• CI now runs lint + tests + a headless GUI smoke test on Python 3.11/3.12 for every PR and push, with job timeouts; Dependabot also tracks GitHub Actions versions.

What's Changed

• Hardening pass: autostart quoting, mutex reliability, lock and restore policies by @neohiro in #7

Full Changelog: v1.0.4...v1.0.5

DNSCrypt Proxy GUI 1.0.4

DNSCrypt Proxy GUI 1.0.4

A major robustness release focused on protecting your existing network configuration.

Highlights

• Your DNS settings are now safe. Before any change, the GUI snapshots your current system DNS configuration and restores it exactly on deactivation or exit - manually configured servers are no longer replaced by DHCP defaults. A new Restore DNS button is always available as a safety hatch.
• Crash-safe by design: if the GUI is force-killed, the proxy child process is cleaned up automatically (Windows Job Object / POSIX watchdog) instead of leaving your DNS pointed at a dead port.
• Visible errors: a rotating log file now records what happens (%LOCALAPPDATA%\DNSCryptClientGUI\logs, ~/Library/Logs/DNSCryptClientGUI, ~/.cache/dnscryptclientgui/logs), and proxy start failures show their actual error output.
• Honest session persistence: explicit Deactivate stays deactivated across restarts; settings persist even when the resolver list cannot be fetched offline.
• Correct configs: relay mappings that reference relays which no longer exist upstream are dropped instead of producing configs dnscrypt-proxy rejects; stale-relay and parser behaviour covered by a new automated test suite.
• Faster refreshes: server/relay lists use conditional downloads - unchanged lists cost almost nothing.
• Better UX on modern systems: crisp text on high-DPI Windows displays, dark-theme-friendly table rows, window size/position remembered, modal relay selector, single-instance guard, cache fields validated (and correctly labelled as entries).

For contributors

• New CI pipeline: lint + unit tests (Python 3.11/3.12) + headless GUI smoke test on every PR/push.
• Release archives now ship with SHA256SUMS.txt; Linux builds target glibc 2.35 for wider distro compatibility.

Notes

• macOS builds remain unsigned - right-click → Open on first launch (or allow in Privacy & Security).
• Place the official dnscrypt-proxy executable next to the GUI, or set its path under Configuration → System Paths.

What's Changed

• Robustness overhaul: exact DNS backup/restore, crash-safety, UX & CI hardening by @neohiro in #6

New Contributors

• @neohiro made their first contribution in #6
