+## v1.6.6
+- Fix: Persistent auto open snap disabled notification(tq to Kaladin)
+- Fix: Crash issues for some devices
+- Fix: upload quality for snaps sent through send override
+- Fix: Refactored the notification card for Auto Open to remove the looping progress bar while the engine is in Monitoring stage(tq to Kaladin)
+- New: Implemented a "Pre Fetch snaps" toggle, when enabled this will pre-fetch the snaps in the auto open queue and load them for the engine to open them efficiently and thus reducing the "Failed to Open..." status(tq to Kaladin)
+- Fix: The Auto Open engine now only fires the status update if the status text, processed count, or queue structural state actually changes. This reduces system wake-ups during idle periods which helps in battery drain management(tq to Kaladin)
+- Fix: Disk Optimization: Previous versions wrote the auto open queue to the disk every 25 snaps, this update modified this to a 3-minute windowed save. This reduces Disk I/O by ~75%, keeping the device from overheating excessively during Auto Open processes(tq to Kaladin)
+
+## v1.6.5
+- New: Performance mode will now be set to max by default!
+- Fix: Several optimizations to the performance mode feature which will make your snapchat experience more smooth!
+- Fix: Crash issues for some devices after enabling spoof
+- Fix: Notification Icon for the Announcements(tq to Kaladin)
+- Fix: Auto Open Engine not processing, stuck on monitor/retry/failed loop causing overheating of the devices(tq to Kaladin)
+- Fix: Refactor the Notification card for the Auto Open to remove dynamic progress bar to add the native progress bar(tq to Kaladin)
+- Fix: Auto Open Statistics have been refactored to now show the dynamic queue status(tq to Kaladin)
+- New: Auto Open Thermal Protection/Throttle toggle, when turned on the processing will be doubled down to reduce the temps of the device to maintain a study temp of 40 C and below(tq to Kaladin)
+
+## v1.6.4
+- New: Performance mode feature!(Smooth & Max)
+- Fix: Failed to init feature Device Spoofer for some devices
+- Fix: Increase the default queue of auto open snaps
+- Fix: user_conversation error spam
+
 ## v1.6.3
 - Fix: Blank Global Settings page
 - New: Backup & Restore option for Randomized Device Profile feature!
