+'''General Stability / Functionality'''
+*Improved internal device watchdog mechanisms to ensure more stable long-term operation.
+*Fixed inconsistent generation of periodic records so they are now created according   to configuration.
+*Fixed the record counter IO so that it increments correctly when new records are created and does not reset unexpectedly in specific configurations.
+*Fixed unnecessary daily activation of a specific event IO. The IO now triggers only on real events instead of once per day.
+*Improved GNSS calculation algorithms for more stable, precise and faster coordinate updates.
+*Fixed issues where idling events were not recorded even when idling detection was configured.
+*Improved movement detection algorithms for more precise event recording.
+*Fixed duplicate or missing “Trip End” status records.
+*Fixed DOUT1 behaviour in Geofence scenarios where a non-zero speed was required even when configuration did not require it.
+*Fixed unnecessary immobilizer status change records.
+*Fixed an issue where the immobilizer scenario could be bypassed under certain conditions and where immobilizer events were generated without values.
+*Fixed incorrect behaviour where the immobilizer scenario was not enforced when no authorization list was configured.
+*Improved logic for DOUT control in immobilizer scenarios so DOUT states are handled consistently, including across sleep/wake transitions.
+*Fixed mismatches between the device-calculated odometer and tachograph   odometer.
+*Fixed issues where fuel data from certain liquid level sensors could be lost, causing incomplete fuel history.
+*Improved total distance and trip distance counting for more accurate mileage   tracking.
+*Included multiple minor internal stability and bug-fix improvements that collectively improve overall system robustness, logging, and performance.
+*Fixed an issue where the device did not enter Deep Sleep mode properly.
+'''Connectivity & Server Communication'''
+*Fixed an issue where the device did not establish a data connection if the APN field was left blank.
+*Improved modem and network handling, including better operator selection and reconnection behaviour, reducing unexpected data link issues.
+*Fixed behaviour where the device continuously contacted the NTP server when GNSS fix was unavailable.
+*Fixed an issue where incorrect NTP responses could lead to timestamps being set in the future.
+*Fixed a problem where the device could receive future timestamps when NITZ was used as the time synchronisation source.
+*Fixed an issue where the device did not send records to the configured duplicate server correctly.
+*Fixed failures to send records to the duplicate server in some TCP/UDP scenarios.
+*Fixed an issue where records were bundled into a single packet rather than being sent individually as expected.
+*Fixed delays in record transmission over UDP.
+*Fixed issues where the device could disconnect from the server after executing certain GPRS or configuration commands.
+*Fixed internal log download issues via over-the-air tools.
+*Fixed a situation where over-the-air firmware update tasks could remain stuck in “Pending” or “Executing” state.
+*Fixed occasional failures of firmware updates performed via the configuration tool, reducing the chance of interrupted or failed local updates.
+*Fixed an issue where the device was not generating Iridium SBD records.
+*Improved RS232 data sending to the Iridium module to ensure that SBD payloads are delivered reliably and without truncation.
+'''Bluetooth / BLE'''
+*Fixed cases where the device generated unnecessary beacon records in stop mode.
+*Fixed issues where advanced beacon packet length information was not generated correctly in advanced beacon mode.
+*Fixed incorrect reading of custom BLE parameter values when the data size was less than three bytes.
+'''MQTT'''
+* Fixed incorrect packing of MQTT packets containing multiple JSON objects when sending to cloud platforms.
+* Fixed an issue where the device did not send data via MQTT to custom cloud endpoints in some configurations.
+* Fixed behaviour where long RS232 messages were not sent correctly via MQTT, which could cause truncation or loss when transmitted as JSON.
+* Improved long-term stability of MQTT JSON operation, increasing reliability for continuous cloud integrations and complex payloads.
+'''Tachograph, K-Line & Driver/Company Data'''
+* Implemented separate internal instance IDs for tachograph IO elements and DDD file  downloading to avoid interference between live data and file download.
+* Fixed a problem where tachograph auto address selection did not work correctly.
+* Fixed an issue where the working tachograph address could change unexpectedly after firmware updates, causing DDD download failures.
+* Fixed errors where remote tachograph file download sessions could be interrupted or not start at all in certain conditions.
+* Fixed behaviour where the tachograph company card number continued to be reported even after the card was removed.
+* Fixed an issue where the tachograph Driver Name field was missing or incomplete in driver information data.
+* Improved character encoding for tachograph Driver Name, including extended and Nordic letters.
+* Fixed an issue where no data was received over K-Line, preventing tachograph and diagnostic data reception.
+* Improved K-Line detection and privacy mode handling, including explicit privacy status reporting where applicable.
+* Enhanced tachograph-related logging and error handling to make diagnostics clearer.
+* Fixed transmission of vehicle and driver identification values (such as VIN, VRN and driver identification) so that accurate identification data is always sent.
+'''FMS / Manual CAN / CAN / Eco Driving & Vehicle Data'''
+* Fixed missing or incorrect reading of specific FMS parameters, including version-specific parameter sets.
+* Fixed fluctuating fuel levels when using FMS or CAN sources, improving fuel accuracy for both standard and EV FMS use cases.
+* Fixed issues where FMS-based speed was not being used correctly as the selected speed source.
+* Improved overall CAN stability so that tachograph CAN and FMS information is not lost due to CAN bus overflow.
+* Fixed incomplete or malformed responses to commands that start or stop Manual CAN (MCAN) transmissions, ensuring clear responses and reliable remote control.
+* Ensured that Manual CAN requests and commands are no longer executed when ignition is OFF.
+'''New Features'''
+* NEW! Added support for storing and sending records from [[FMC650 System settings#Records Saving/Sending Without TS|RAM memory]]. recommended for rapid data sending i.e. data saving every second etc.
+* NEW! Implemented a new feature called the “[[FMC650 LVCAN I/O,FMS IO and Tachograph data elements#Driver Working State Filters|one minute rule]]” for tachograph driving state, reducing unnecessary state toggling and improving driving/rest detection accuracy.
+* NEW! [[FMC650 Thermograph#Apache|Apache Thermograph]].
+* NEW! [[FMC650 TrailerCAN|Trailer CAN]] functionality.
+* NEW! Implemented [[FMB scanevfms|“scanevfms“]] command for diagnosing electric trucks, providing targeted EV CAN diagnostics.
+* NEW! Implemented “[[FMB can＿info|can_info]]“ command that returns details of the CAN bus (baud rates, modes and other key parameters), aiding diagnostics.
+* NEW! Updated the “[[FMB tachocheck|tachocheck“]] command to show more detailed information.
+'''Configuration, Parameters & Tools'''
+* Fixed an issue where a single setparam command could not change multiple parameters at once.
+* Fixed behaviour where the odometer command always returned a GNSS-based odometer value regardless of the configured odometer source.
+* Fixed cases where the device disconnected unnecessarily from the configurator.
+* Fixed an issue where the SIM PIN was not remembered after soft or hard reset.
