'''General'''
*Resolved high CPU usage that could affect device performance and responsiveness.
*Fixed AVL records from the SD card no longer being sent until a manual restart.
'''Connectivity & Server Communication'''
*Device now checks for and responds to SMS commands while in Online Deep Sleep (ODS) mode.
*Fixed FOTA WEB update failure after a hard reset when the configured Server 1 address is unavailable.
*Fixed corrupted UDP data when AVL records exceed 512 bytes
'''Tachograph & DDD'''
*Fixed "unexpected file type" error during VDO Gen2v2 DDD file download.
*Improved WEB TACHO link timeout handling for Stoneridge tachographs — the 15-minute timeout is now extended on each server response, preventing premature disconnection during prolonged authentication (BUSY responses).
'''CAN & LV-CAN'''
*Fixed LV-CAN200 not accepting certain program numbers (e.g., 13853); the device now returns the configured value correctly.
