 ## Change logs
 
+# v1.3.8
+* Added disabling Dolby control support for USB DAC's on HyperOS not to reboot
+* Excluded "MotorolaSettingsProvider" on Motorala devices only for avoiding their bootloop
+* Changed the USB period_us from 2250 usec to 2000 usec to optimize for 48 kHz Opus tracks (recent majority)
+
 # v1.3.7
 * Added "compatible Magisk-mirroring" message for incompatible Magisk variants
 * Adjusted re-sampling parameters for old devices
