+#
+# RELEASE v0.9.6-2 - Talkkonnect Terminal Fix
+#
+# What's NEW in v0.9.6-2:
+# - CRITICAL FIX: Talkkonnect systemd service terminal initialization error
+#   * ISSUE: talkkonnect service fails with "Cannot Initialize Terminal" error
+#     Error logs show: "alert: Cannot Initialize Terminal" followed by abnormal termination
+#   * ROOT CAUSE: talkkonnect uses termbox-go for terminal UI, which requires a TTY
+#     Systemd services don't provide a TTY by default, causing initialization failure
+#   * FIX: Added two changes to talkkonnect systemd service:
+#     - Environment="TERM=dumb" tells terminal library to use minimal mode
+#     - StandardInput=null explicitly prevents terminal initialization attempts
+#   * RESULT: talkkonnect now runs successfully as a headless systemd service
+# - All features from v0.9.6-1 included
+#
+# RELEASE v0.9.6-1 - Bluetooth Edition (No WebRTC/Jitsi)
+#
+# What was in v0.9.6-1:
+# - NEW: Bluetooth audio support (A2DP sink/source)
+#   * Pair bluetooth speakers, headsets, and microphones
+#   * Auto-reconnect to known devices
+#   * Simple pairing interface via addon menu
+# - NEW: Bluetooth device management
+#   * List, pair, unpair, and trust bluetooth devices
+#   * Auto-connect on boot for trusted devices
+#   * Battery status for supported devices
+# - REMOVED: WebRTC intercom system (use talkkonnect instead)
+# - REMOVED: Jitsi web intercom (use talkkonnect instead)
+# - RECOMMENDED: Use talkkonnect addon for native PTT intercom
+#   * Better audio quality than web-based solutions
+#   * Lower latency
+#   * Works with Bluetooth PTT buttons
+# - All fixes from v0.9.5-12 included
+#
+# RELEASE v0.9.5-12 - Site-Specific Extension Fix
+#
+# What was in v0.9.5-12:
+# - CRITICAL FIX: Time extensions now properly cleared on automatic rotation
+#   * ISSUE: Extensions granted on one site would persist when automatically rotating to another site
+#     Example: User gets 15-min extension on Site A, Site A's timer expires and rotates to Site B,
+#     Site B would stay paused for the remaining extension time (incorrect behavior)
+#   * ROOT CAUSE: rotateToNextSite() function didn't clear inactivityExtensionUntil
+#     Manual navigation (Ctrl+Tab, swipe) already cleared extensions, but automatic rotation didn't
+#   * FIX: Added inactivityExtensionUntil=0 in rotateToNextSite() function (line 4537)
+#     Extensions now site-specific: when navigating away (manually OR automatically), rotation resumes
+#   * BEHAVIOR: Extensions only apply to the site they were granted on
+#     If user grants 30-min extension to read a recipe, finishes in 20 min, and navigates away,
+#     the new site will rotate normally (extension doesn't follow to new site)
+# - All fixes from v0.9.5-11 included
+#
+# RELEASE v0.9.5-11 - BrowserView Attachment Fix
+#
+# What was in v0.9.5-11:
+# - CRITICAL FIX: Resolved BrowserView attachment error on password unlock
+#   * ERROR: When unlocking password screen, users received error:
+#     "Error: Given BrowserView is not attached to the window"
+#     This caused a white screen requiring Ctrl+Alt+Del → Reload to recover
+#   * ROOT CAUSE: showLockoutScreen() removes all BrowserViews (security feature)
+#     but unlockScreen() called setTopBrowserView() without first adding the view back
+#     Electron requires view to be attached before setting as top
+#   * FIX: Added mainWindow.addBrowserView() before setTopBrowserView() in attachView()
+#     function (line 4538-4544), wrapped in try-catch for already-attached cases
+# - All fixes from v0.9.5-10 included
+#
+# RELEASE v0.9.5-10 - Enhanced Password Lockout Security
+#
+# What's NEW in v0.9.5-10:
+# - SECURITY FIX: Browser views now completely hidden when locked
+#   * All browser views detached from mainWindow during lockout
+#   * Prevents content visibility when password screen is active
+#   * Users cannot see any URLs or content until password is entered
+# - IMPROVED: Power menu displays on solid black screen when locked
+#   * Power menu now shows on lockoutWindow instead of mainWindow
+#   * No content visible behind power menu when system is locked
+# - SIMPLIFIED: Removed time-based lockout restrictions
+#   * Eliminated "Only enforce lockout during specific hours?" prompt
+#   * Password protection now always active when enabled
+#   * More reliable and predictable security behavior
+# - All fixes from v0.9.5-9 included
+#
+# RELEASE v0.9.5-9 - CRITICAL Inactivity Lockout Fix (Simplified)
+#
+# What was in v0.9.5-9:
+# - CRITICAL FIX: Inactivity lockout now works (was never triggering)
+#   * Removed lockoutActivityTime reset from markActivity() function
+#   * markActivity() was being called on EVERY mouse move, click, keyboard press
+#   * This constantly reset the lockout timer, preventing it from ever triggering
+#   * Now lockout timer ONLY resets when user unlocks or selects time extension
+# - All fixes from v0.9.5-8 included
+#
+# ROOT CAUSE:
+# The markActivity() function (line 3904-3906) was resetting lockoutActivityTime:
+#   markActivity(){
+#     ...
+#     if(enablePasswordProtection && lockoutTimeout > 0){
+#       lockoutActivityTime = now;  // ← THIS WAS THE PROBLEM
+#     }
+#   }
+#
+# markActivity() is called on EVERY:
+# - Mouse move
+# - Mouse click
+# - Keyboard press
+# - Page load
+# - Focus change
+#
+# This meant lockoutActivityTime was CONSTANTLY being reset, so the lockout
+# timer could NEVER reach the configured timeout (e.g., 17 minutes).
+#
+# FIX:
+# Removed the lockoutActivityTime reset from markActivity() entirely.
+# Now lockoutActivityTime only resets when:
+# 1. User unlocks the screen (in unlockScreen() function)
+# 2. User selects a time extension (in showPauseDialog/showInactivityPrompt)
+#
+# This is simple and correct: lockout should trigger after X minutes of
+# inactivity, regardless of whether user is actively using the site or not.
+# Time extensions explicitly extend the lockout timer when user confirms presence.
+#
+# RELEASE v0.9.5-6 - Boot Password Sequence Fix
+#
+# What was in v0.9.5-6:
+# - Boot password now required BEFORE showing any websites
+# - Limited power menu when locked (no Reload option)
+#
+# TROUBLESHOOTING: If navigation (Ctrl+Tab, swipe) doesn't work:
+# - Check your config.json for sites with duration: -1 (hidden sites)
+# - Hidden sites don't appear in rotation and don't count toward navigation
+# - Ensure you have at least 2 visible sites (duration >= 0) for navigation to work
+# - Run the install script menu option 1 to view current configuration
+#
+# RELEASE v0.9.5-4 - CRITICAL Security and Compatibility Fixes
+#
+# What was in v0.9.5-4:
+# - CRITICAL SECURITY FIX: Restricted polkit permissions to prevent Ctrl+Alt+Del bypass
+#   * Changed org.freedesktop.login1.* (ALL actions) to specific power operations only
+#   * Prevents session switching and VT access that could bypass kiosk security
+# - CRITICAL SECURITY FIX: Added X server ServerFlags to block VT switching
+#   * Disabled Ctrl+Alt+F1-F12 VT switching with DontVTSwitch option
+#   * Disabled Ctrl+Alt+Backspace X server kill with DontZap option
+#   * Added AllowClosedownGrabs protection
+# - SECURITY: Enhanced LightDM greeter security settings
+#   * Hide user list, disable manual login, disable guest account
+# - FIXED: Autostart script compatibility errors ([[: not found)
+#   * Converted bash-specific [[ ]] syntax to POSIX-compliant [ ] syntax
+#   * Fixed all conditional tests in display schedule and quiet hours logic
+# - FIXED: xbindkeys errors (missing .xbindkeysrc)
+#   * Now creates empty .xbindkeysrc file to prevent xbindkeys startup errors
+#
+# RELEASE v0.9.5-3 - Extension and Manual Navigation Fixes
+#
+# What was in v0.9.5-3:
+# - CRITICAL FIX: Time extensions now work correctly (15 min actually = 15 min)
+#   * Removed inactivityExtensionUntil=0 from markActivity() function
+#   * Extensions no longer cleared by clicking extension buttons
+#   * Pause button extensions now work for full selected duration
+#   * Manual site timeout extensions now work for full selected duration
+# - FIXED: Manual tab switching now clears extensions appropriately
+#   * Ctrl+Tab, Ctrl+Shift+Tab, swipe gestures now clear active extensions
+#   * Prevents confusion when user manually navigates during extension
+#
+# RELEASE v0.9.5-2 - Settings Persistence & Timing Fixes
+#
+# What was in v0.9.5-2:
+# - CRITICAL FIX: Sites no longer wiped when editing password/pause/OSK settings
+#   * Added load_existing_config() to preserve all settings before save
+#   * Fixed empty URLS/DURS arrays from overwriting sites in config.json
+# - CRITICAL FIX: Password protection now properly saved/persists on reboot
+# - CRITICAL FIX: Sites now properly saved/persist on reboot
+# - FIXED: Time extension now works on correct site (not next rotation site)
+#   * Pause dialog blocks rotation while user is selecting time
+#   * Inactivity prompt blocks rotation while user is responding
+# - FIXED: Pause button now properly blocks rotation for selected duration
+# - FIXED: Manual site timeout popup no longer appears 1 min after extension expires
+#   * Extension expiration now properly resets lastUserInteraction timer
+# - NEW: Cancel/exit option in password and optional features menus
+#   * Menus now ask "Save these changes?" before applying
+#   * Answer "no" to discard changes without affecting config
+# - ENHANCED: Comprehensive settings display on main menu
+#   * Shows all sites with [HOME] marker
+#   * Shows home URL and inactivity timeout
+#   * Shows pause/keyboard button status
+#   * Shows complete password protection configuration
+#
+# RELEASE v0.9.5-1 - Lockout Stay Locked Fix
+#
+# What was in v0.9.5-1:
+# - CRITICAL FIX: Lockout screen now stays locked until password entered
+# - Fixed rotation timer continuing to run during lockout
+# - Added isLockedOut checks to all navigation functions
