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, var→let/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 (zh → zh-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
