======================== * Added support to VW MQB/PQ platform. (Thanks to @dingliangxue) * Updated to stop charging after 3 hrs. (Thanks to @Wei) * Removed Impact Detection in Dashcam. * Fixed a bug caused by enabling "Noctua Mod". (Thanks to @阿濤) * Fixed alert issue in waze mode. (Thanks to @axandres) * Fixed unable to display "UPDATING" icon issue. * Added "Allow Continuous Auto Lane Change" Toggle. (Thanks to @阿濤) * Fixed setting page crash issue. (Thanks to @salmankhan, @Wei) * Fixed issue that keep showing update prompt. (Thanks to @Sky Chang)
