Changelog

v1.3.0 — Bug Fixes &amp; 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 &amp; Health Scan

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

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

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

💾 <strong>Backup Management:</strong>
<ul><li>Added delete button for each backup in the Manage Backups panel — you can now individually remove backups you no longer need</li><li>Export filename now includes human-readable date and time (e.g. <code>gpm-backup-2026-04-05_14-07-34.json</code>) instead of random numbers</li><li>Consolidated 7+ backup keys into a single slot — prevents storage quota overflow</li><li>Quota monitoring warns at 80% of 10MB limit and skips backup automatically if storage is nearly full</li><li><code>deleteBackupConfirm</code> translation added for all 17 languages</li></ul>
⭐ <strong>Favorites:</strong>
<ul><li>Star/unstar any chat for quick access across all projects — replaces the old tag/label system</li><li>Starred chats sorted by date for easy browsing</li></ul>
🛡️ <strong>Data Safety:</strong>
<ul><li>Fixed critical schema version conflict between storage and background scripts that could cause data loss during extension updates</li><li>Cross-tab write lock with 5s timeout prevents data corruption when using multiple Gemini tabs</li><li>Atomic saves — projects and chat mappings are now written in a single operation</li><li>3-phase deletion verification with safety ratio check ensures chats are never falsely removed</li><li><code>unlimitedStorage</code> permission removed — no longer needed with the new quota-aware design</li></ul>
v1.2.3 — Post-Import Cleanup

v1.2.2 — Chrome Web Store Compliance

v1.2.1 — Deleted Chat Sync Fix
<ul><li>🐛 <strong>Fixed:</strong> Chats deleted from Gemini's native interface now automatically disappear from GPM project folders — no more ghost entries</li><li>🛡️ <strong>Added:</strong> Two-phase deletion verification with debounce prevents false positives from Gemini's lazy-loading or DOM recycling</li><li>🛡️ <strong>Added:</strong> Safety guard skips cleanup when sidebar is still loading (zero chat links detected)</li></ul>
v1.2.0 — DOM Resilience &amp; Language Expansion Update
