Changelog

v1.3.0 — Bug Fixes & Performance

Fix: Drag-drop chat title was stale — now reads live from DOM at drag time Fix: Search input stripped spaces on each keystroke — spaces are now preserved Fix: Prevented project section from injecting into wrong element (top nav/main content) Fix: Memory leak — _aliasRecheckInterval and _fallbackDeletionInterval never cleared on re-init Fix: Storage lock chain broke after first error, subsequent writes ran without synchronization Fix: Migration failure left storage in inconsistent state with no recovery marker Fix: Backup panel calls not properly error-handled (uncaught promise rejections) Fix: Integrity auto-fix didn't persist chatMap for orphan/missing-parent/circular-ref fixes Fix: Undo delete-project didn't restore parent-children relationships for nested projects Fix: Arrow key keyboard shortcuts didn't work (key normalization bug) Fix: Recovery UI style element never removed on dismiss (DOM accumulation) Fix: Duplicate gpmStopHealthMonitor call in reset Fix: Drag-drop isDescendant used stale closure data instead of fresh storage Fix: Redundant storage read in chat drop handler Perf: Projects now inject immediately into sidebar even before chat links load Perf: Sidebar content wait reduced from 10s to 3s Perf: Navigation re-inject delay reduced from 600ms to 300ms Perf: Storage reads parallelized in render (getProjects + getChatMap) Perf: gpmGetCurrentChatId() cached per render instead of per chat row Perf: Backup creation serialized with lock to prevent concurrent overwrite Quality: gpmClearSelectorCache uses Object.keys() instead of for...in Quality: Toast removal guard added to prevent infinite loop

v1.2.8 — Gemini UI Compatibility & Health Scan

🔧 Gemini New UI Compatibility:

  • Fixed Projects section appearing in the wrong place (top bar instead of left sidebar) on Gemini's redesigned layout
  • Sidebar is now discovered by climbing up from chat links instead of relying on fragile CSS selectors
  • Quick Prompt button no longer flickers — added fast-path cache, stale insertRef guard, and floating button idempotency
  • Reduced initialization latency by parallelizing storage, sidebar wait, and non-blocking setup steps
🛡️ Health Scan & Stability:
  • Fixed critical gpmInit deadlock: _initializing flag is now guaranteed to clear via try/finally, preventing permanent init lock after any error
  • Cross-tab write lock (_withLock) now skips execution instead of running unlocked when lock cannot be acquired
  • Added createdAt/updatedAt timestamps to all newly created/updated projects
  • Timer leak fixes: gpmCleanupObservers now clears _deletionCheckTimer and _sidebarStabilizeTimer
  • Auto-assign promise (GPMStorage.assignChat) now has .catch to prevent unhandled rejections
  • Sidebar observer resilience: if gpmInit throws inside observer, it re-attaches itself for retry
🧹 Code Quality:
  • Lint: 88 warnings → 0 (dead globals removed, varlet/const, unused params prefixed)
  • ESLint globals cleaned up: removed _gpmIsValidSidebar, GPM_LANG, showToast, gpmFindInsertionPoint; added gpmStopHealthMonitor, gpmObserveForSidebar
v1.2.7 — Stability & Reliability Update

🐛 False Deletion Fix:

  • Fixed false-positive "chat deleted" detection when Gemini's sidebar loads chats lazily — the extension no longer treats unloaded chats as deleted
  • Added sidebar stabilization tracking: deletion detection now waits until the sidebar chat count stabilizes (2 consecutive identical counts) before running any checks
  • Stricter threshold: deletion check is skipped entirely if DOM chat count is less than stored chat count, preventing premature false positives
  • Stabilization resets on tab visibility change to handle fresh sidebar loads correctly
⌨️ Input Fixes:
  • Fixed a regression where the Space key stopped working in Gemini's message composer because global keyboard shortcuts were incorrectly intercepting contenteditable input fields
  • Made keyboard shortcut initialization idempotent to prevent duplicate listeners during re-initialization
🔄 Data & Sync Reliability:
  • Reworked routine UI refresh sync to react to chrome.storage changes instead of relying on tab messaging for standard refresh flows
  • Made import and backup restore flows atomic by validating first, creating a backup, and writing the full target state in a single storage operation
  • Reduced sync fragility by removing routine dependency on chrome.tabs messaging for local refresh propagation
🧪 Test & Stability Improvements:
  • Added coverage for duplicate keyboard shortcut initialization
  • Strengthened test and mock infrastructure for storage change handling
  • Improved DOM observer cleanup behavior during re-initialization and tests
v1.2.6 — Security Hardening

🔒 Input Sanitization:

  • Switched to allowlist-based text sanitization — only known-safe characters are allowed (letters, numbers, punctuation, emoji, and international characters)
  • Turkish, CJK, Arabic, and other Unicode scripts are fully preserved while blocking potential XSS characters
⌨️ Input Fixes:
  • Fixed a regression where the Space key stopped working in Gemini's message composer because global keyboard shortcuts were incorrectly intercepting contenteditable input fields
  • Made keyboard shortcut initialization idempotent to prevent duplicate listeners during re-initialization
🔄 Data & Sync Reliability:
  • Reworked local sync handling to react to chrome.storage changes instead of relying on tab messaging for routine UI refreshes
  • Made import and backup restore flows atomic by validating first, creating a backup, and writing the full target state in a single storage operation
🛡️ Error Handling:
  • Invalid JSON imports now show a clear error message with character position hint instead of crashing silently
  • Lock chain errors are now logged to console for debugging instead of being silently swallowed
🧹 DOM Safety:
  • Replaced innerHTML usage in bulk toolbar with safe DOM methods (createElement + textContent) — eliminates potential XSS injection vector
v1.2.5 — Backup Management & Data Safety Overhaul

💾 Backup Management:

  • Added delete button for each backup in the Manage Backups panel — you can now individually remove backups you no longer need
  • Export filename now includes human-readable date and time (e.g. gpm-backup-2026-04-05_14-07-34.json) instead of random numbers
  • Consolidated 7+ backup keys into a single slot — prevents storage quota overflow
  • Quota monitoring warns at 80% of 10MB limit and skips backup automatically if storage is nearly full
  • deleteBackupConfirm translation added for all 17 languages
Favorites:
  • Star/unstar any chat for quick access across all projects — replaces the old tag/label system
  • Starred chats sorted by date for easy browsing
🛡️ Data Safety:
  • Fixed critical schema version conflict between storage and background scripts that could cause data loss during extension updates
  • Cross-tab write lock with 5s timeout prevents data corruption when using multiple Gemini tabs
  • Atomic saves — projects and chat mappings are now written in a single operation
  • 3-phase deletion verification with safety ratio check ensures chats are never falsely removed
  • unlimitedStorage permission removed — no longer needed with the new quota-aware design
v1.2.3 — Post-Import Cleanup
  • Added: Automatic cleanup after importing/restoring backup — deleted chats are now removed from GPM projects
  • 🔄 Added: Retry logic (3 attempts, 1.5s intervals) waits for Gemini sidebar to load before cleanup
  • 💬 Added: User notification showing how many deleted chats were cleaned up
  • 🌍 Added: deletedChatsCleaned message in all 17 languages
v1.2.2 — Chrome Web Store Compliance
  • 🐛 Fixed: zh_CN locale folder renamed to zh-CN (Chrome requires hyphen format)
  • 🐛 Fixed: Removed illegal nul file that caused Chrome extension loading error
  • 🌍 Updated: Chinese language code standardized across all files (zhzh-CN)
v1.2.1 — Deleted Chat Sync Fix
  • 🐛 Fixed: Chats deleted from Gemini's native interface now automatically disappear from GPM project folders — no more ghost entries
  • 🛡️ Added: Two-phase deletion verification with debounce prevents false positives from Gemini's lazy-loading or DOM recycling
  • 🛡️ Added: Safety guard skips cleanup when sidebar is still loading (zero chat links detected)
v1.2.0 — DOM Resilience & Language Expansion Update
  • 🔍 Added: Search bar in Projects sidebar — quickly filter and find chats across all projects
  • 🛡️ Added: Self-healing DOM observer — extension auto-recovers when Gemini re-mounts its page
  • 🛡️ Added: Adaptive selector engine with structural discovery fallbacks for sidebar and input area
  • 🛡️ Added: Multi-strategy toolbar detection (CSS classes, content-based "Tools" label search, structural walk-up)
  • 🛡️ Added: DOM health monitor with container watchdog
  • 🐛 Fixed: Quick Prompt ⚡ button stuck as floating fallback — retry logic now properly relocates it into the toolbar once available
  • 🐛 Fixed: MutationObserver and interval check suppressed by floating button presence — both now continue retrying until toolbar placement succeeds
  • Improved: Quick Prompt button toolbar discovery walks up from "Tools" label to find proper toolbar row container
  • Improved: MutationObserver uses content-based detection ("Tools" label in 17 languages) to trigger toolbar injection
  • 🌍 Added: 8 new languages: Arabic (العربية), Bengali (বাংলা), Hindi (हिन्दी), Indonesian (Bahasa Indonesia), Korean (한국어), Portuguese (Português), Thai (ไทย), Vietnamese (Tiếng Việt)
  • 🐛 Fixed: Data import now correctly preserves Hindi, Korean, and Arabic language preferences
  • 📊 Expanded from 9 → 17 languages total
v1.1.0 — Data Safety Update
  • 🐛 Fixed: Critical bug where chats assigned to projects would randomly disappear due to false-positive cleanup triggered by Gemini's lazy-loading sidebar
  • 🛡️ Added: Auto-backup before every save — your data is always protected
  • 🛡️ Added: "Restore from Backup" button in Settings with timestamp and content preview
  • 🛡️ Added: Mutex-based write serialization prevents data corruption across multiple tabs
  • Improved: Cross-tab sync debounced (300ms) for smoother multi-tab experience
  • 🗑️ Removed: Aggressive auto-cleanup that incorrectly removed chats not visible in sidebar DOM
v1.0.0 — Initial Release
  • Project and subfolder creation with custom icons and colors
  • Drag & drop chat organization
  • Quick prompts with search, edit, backup/restore
  • 10-language localization
  • Native Gemini UI integration with dark/light mode
