ReVoltVPN/CHANGELOG.md

Changelog

All notable changes to the ReVoltVPN Flutter app. Versions follow semver: MAJOR.MINOR.PATCH

---

[3.3.0] — 2026-08-30

Added

• Session countdown in the VPN notification, updated each second while connected.

Fixed

• Session-expiry desync — the app could show "Online" with no internet after the server ended the session. The countdown no longer freezes when a poll fails.
• Notification Disconnect button disappeared a second after connecting. Re-posting the foreground notification replaces it wholesale, so the action, colour and tap-intent flutter_vless sets are now rebuilt rather than dropped.
• Speed readout divided the byte delta by the nominal poll interval instead of the real time between polls — wrong by up to 6x around every background switch.
• Settings toggles now apply at launch. Rain, lightning and haptics were only read from disk when Settings mounted, so an effect turned off came back — ticker and all — on every relaunch, and haptic feedback did nothing until Settings had been opened at least once.
• Haptic feedback now fires mediumImpact() instead of lightImpact() (which is imperceptible on many Android devices), wrapped best-effort so a platform vibration failure cannot fail a connect/disconnect, with a preview tap when the toggle is switched on.
• First-launch disclosure dialog said data was linked to "your account". It is linked to a randomly generated device ID, and the policy is in the sidebar, not on a website.
• Sidebar "Settings" and "Check for updates" used the drawer's context after Navigator.pop() — a defunct context. They now capture the root navigator (and messenger) before closing the drawer. (Fix ported from Naveax's review.)

Performance

• Rain overlay ticks only while enabled, repaints through a scoped Listenable instead of rebuilding every frame, and precomputes drop colours.
• Lightning no longer fires strikes while disabled.
• Connect button pulse pauses when backgrounded; brand image hoisted out of the per-frame rebuild.
• Server poll drops to 30 s while backgrounded (5 s foreground), with an immediate re-sync on resume. The 1 s countdown keeps running.
• Health probe runs only while disconnected, and pauses in the background.
• Speed and support widgets rebuild on value change instead of every second.
• Notification channel is created once per process, not once per second.

Changed

• VLESS engine initializes under the splash screen; the intro waits on VpnConnection.ready (8 s cap) before showing the main screen.
• AdMob SDK init moved off the blocking pre-runApp() path so startup cannot hang on an unreachable Google endpoint.
• app_config.example.dart drops the dead bootstrap fields and documents hivemindApiPublic in their place.
• .gitignore reorganized around type and directory rules; the enumerated filename list is gone (redundant with the type rules) and .claude/ is now ignored.

Security

• Update checker pins the release URL to this repo's path on github.com, not just the host. Anything else falls back to the releases page.
• Notification timer updates are gated on a live tunnel, so a late tick cannot leave an ongoing notification with no foreground service behind it.
• Dropped READ_EXTERNAL_STORAGE, which flutter_vless pulls in but the app never uses (least privilege).
• Pinned the Gradle 8.14 distribution SHA-256; validateDistributionUrl enabled (supply-chain integrity).

Build & tooling (ported from Naveax)

• Removed the deprecated android.enableR8 flag.
• Added analysis_options.yaml (flutter_lints, local_packages/** excluded, avoid_print).
• Added .gitattributes to pin LF line endings repo-wide.
• Credit: reviewed and ported from Naveax.

Docs

• Privacy policy: disclosed that the server sees the connecting IP, corrected the "stored in memory" claim, and documented consent being changeable from the sidebar.

[3.2.2] — 2026-08-08

Fixed

• Updated Discord invite link.

[3.2.1] — 2026-08-08

Google Play compliance

• Added first-launch data disclosure dialog ("Before you connect") explaining that connection duration and data usage are logged for quota enforcement, and that traffic content is never monitored.

[3.2.0] — 2026-08-08

DPI hardening

• Spoof Chrome-on-Android User-Agent on all API calls instead of Dart/3.x.
• Renamed domain from getrevolt.app to userevolt.app.

Branding

• App name changed from "REVOLT VPN" to "Revolt VPN" across manifest, splash, notification, and VLESS URL remark.

Notification

• Removed duplicate flutter_local_notifications notification. Only the Android VPN foreground-service notification remains — non-swipeable.
• Patched flutter_vless native code to use custom notification icon (@drawable/notification_icon) with dark background (#0D1117).

Connection reliability

• Merged five separate disconnect paths into a single idempotent _doDisconnect() gate. Eliminated race between timer ticks and VPN teardown where the countdown could briefly show -1.
• stopVless() timeout (5 s) now correctly shows an error instead of silently pretending the VPN disconnected while the tunnel was still alive.

AdMob bypass

• kDebugMode guard removed — the debug AdMob callback now fires in release builds so release APKs can create sessions without real ads during testing. The real gate is ADMOB_BYPASS on the server.

Fixed

• Notification icon: Replaced five density-specific ic_launcher.png files with notification_icon.png, then reverted to avoid changing the home-screen icon. The custom icon is now injected through flutter_vless's initializeVless() parameters.

[3.1.0] — 2026-08-06

Architecture — domain-free client

• Zero domain strings in APK. RKN has nothing to DNS-block. API calls go through the Reality tunnel to 10.254.254.1:5000, redirected to Flask by Xray's api freedom outbound (redirect: 127.0.0.1:5000).
• Bootstrap tunnel. Bundled Reality config in APK → connect → fetch real per-session VLESS URL from inside the tunnel → reconnect. Bootstrap client permanently in xray_config_reality.json, restricted by Xray routing to internal API only.
• serverDomain removed from AppConfig. fetchConfigThroughTunnel() replaces fetchConfigWithPolling(). connect() rewritten.

Protocol — TCP to XHTTP

• Transport: TCP → XHTTP (H2 stream-up with Reality). No more XTLS-Vision, no flow field. Path-hidden behind /revolt.

Fixed

• RenderFlex overflow — status bar text wrapped in Flexible with TextOverflow.ellipsis to prevent overflow on narrow screens (≤360dp).
• Circular import — removed import 'package:revoltvpn/main.dart' from sidebar_drawer.dart. SidebarDrawer converted to StatefulWidget; version footer loaded via PackageInfo.fromPlatform().
• Client hot-reload was silently broken — xray api adi no-op. Fixed: adu/rmu commands per Xray HandlerService spec.
• Missing XHTTP path param in VLESS URL — now reads xhttp_path from /session/status.
• providerBundleIdentifier was com.revoltvpn.app — must match com.paladinvpn.app for VPN service registration.
• Reality keypair generated (was placeholder). Throttle uplinkOnly/downlinkOnly corrected (seconds, not bytes/sec). Fallback rate limits removed (fingerprint).

Added

• Settings screen — reached from a new sidebar row (between Website and Check for updates). Slide-from-right navigation via PageRouteBuilder. Folder: lib/screens/settings/ with one file per feature in in_settings/.
• Haptic feedback toggle — on/off switch in Settings for lightImpact() vibration on successful connect/disconnect. Default: off. Uses sync-bool pattern (no await on tap, no SharedPreferences in connect button).
• Rain/Lightning effect toggles — two switches in Settings to control the animated background effects. Default: on. Effects detect the toggle within one frame (no Provider/notifier needed).

Changed

• Timer box spinner removed — the "Connecting…"/"Syncing…" spinner under the countdown was redundant with the connect button's spinner. Timer card is now a clean countdown only (gray '00:00:00' when idle).
• Sidebar now has 7 rows (added Settings). FRONTEND_POLISH_REVIEW.md fully triaged: 4 items fixed, 11 skipped.

Server

• api outbound + 3 routing rules in xray_config_reality.json (bootstrap isolation + API routing). Permanent bootstrap client. Hivemind unchanged.
• xhttp_path in /session/status response.
• Full deployment guide: SERVER_DEPLOYMENT.md.

[2.0.7] — 2026-07-31

Fixed

• Notification bug — SessionTimer.stop() now cancels the persistent Android notification on user-initiated disconnect.
• Concurrent sync guard — _syncInProgress flag prevents duplicate HTTP requests from overlapping in _syncWithHivemind().
• Debug bypass gate — AppConfig.enableAdBypass replaces kDebugMode for fake AdMob callback. Tree-shaken in release builds.

Changed

• Responsive layout — main screen uses LayoutBuilder with proportional fractions. Scales to any screen size.
• Dynamic version — sidebar footer reads from PackageInfo instead of hardcoded string.
• Swarm/log blocked — nginx returns 404 for /api/swarm and /api/log. Monitoring runs locally via swarm_watch.py.

Added

• Update checker in sidebar — polls GitHub Releases API.
• Website button in sidebar → opens https://userevolt.app.
• Timer syncing indicator — spinner during handshake.
• Dependency: package_info_plus.

Server

• /session/stop fetches stats BEFORE popping session (race fix).
• XrayManager._stats_lock for diagnostic counter thread safety.
• ManagementLoop._start_lock prevents TOCTOU on daemon startup.
