Device Management In the configuration repository, the configuration type was not saved correctly when adding a new configuration snapshot, leading to unexpected behavior. With this change, the configuration type is now properly persisted when saving the configuration snapshot. DM-3791 10.18.0.273 ui-c8y
LWM2M The issue with LWM2M firmware updates via the PULL HTTP(s) method in a clustered agent environment has been resolved. Previous version used to have a data serialization problem that prevented HTTP(s) endpoint to start and blocked the update process. DM-3848 10.18.0.457 cumulocity
OPC UA In certain ARM64-based environments, the OPC UA gateway may fail when attempting to call a specific 64-bit system function that might be missing in some base Docker images. This issue has now been resolved. If this function is missing, the service will attempt to call a default system function before failing. DM-3867 10.18.0.464 cumulocity
OPC UA The OPC UA gateway creates a local database to store essential data, including a list of executed operation IDs. As this list expands, the database file consumes more disk space. This issue has been resolved by introducing an in-memory cache to store executed operation IDs with each entry set to auto-expire after 24 hours. The fix also includes a one-time cleanup process during the gateway startup to reduce the size of the existing file. DM-3800 10.18.0.468 cumulocity

LWM2M In earlier versions of the LWM2M agent, only a single agent within the cluster was responsible for hosting the firmware image via an HTTP endpoint. This setup could occasionally lead to 401 responses when devices attempted to download the firmware. With the latest update, all agents in the cluster are synchronized and now host the same set of firmware images, ensuring seamless and reliable firmware downloads. DM-3738 10.18.0.439 cumulocity

Actility Actility device registrations using an enterprise connection were failing due to an issue with the enterprise connection creation. This issue has been resolved by fixing the enterprise connection creation step. DM-3560 10.18.0.419 cumulocity
Loriot Newly established Loriot connections failed initially because the user account created for sending uplink requests from devices lacked the necessary admin permissions. This issue has been resolved by granting the required permissions to both existing and new connections. DM-3411 10.18.0.400 cumulocity
LWM2M When a LWM2M 1.1 send request that includes multiple timestamps has been received, the object resource mapping actions have in some cases been processed multiple times by the LWM2M agent. This issue has been resolved to ensure that mapping actions get only triggered once. DM-3620 10.18.0.406 cumulocity
LWM2M Previously, the execution of LWM2M device operations was limited to a specific timeframe following the device's registration with the platform. However, this timeframe remained static even after the device underwent registration updates, despite the previous operational window not yet expiring. This limitation has now been addressed, ensuring that each LWM2M device registration update extends the device operations timeframe. DM-3601 10.18.0.407 cumulocity

Device Management An old data model migration mechanism was erroneously removing installed software information from devices when the Advanced Software Management microservice was resubscribed or restarted. This mechanism has entirely been removed so that existing data is no longer modified. DM-3475 10.18.0.398 cumulocity
Device Management The properties library schema definition for the c8y_SoftwareList fragment did not match the actual managed object properties. Hence, when the Software property was selected in the "Device data" widget no data was shown. The property is now called Software list and displays all software items contained in the c8y_SoftwareList fragment. DM-3470 10.18.0.254 ui-c8y

Device management Added support for rendering dropdown fields in JSON Schema Formly in the extensible device registration. DM-1921 10.17.67.0 UI
Device management The step headers "1, 2, 3 ..." of the "Connect smartphone" wizard can no longer be clicked. The navigation now works exclusively via the buttons in the footer of the wizard. Moreover, the text which is displayed if an error occurs during the registration has been revised. If the last step ends in an error message, the last header now also reflects this error status. DM-1930 10.17.25.0 UI
LWM2M The performance of the migrateLwm2mDevices operation has been improved. New command line arguments have been introduced with the operation. A list of legacy LWM2M devices can be specified directly from the shell command. Moreover, the migration of the LWM2M client registration objects can be skipped by using an argument. For details, refer to LWM2M > LWM2M connector device > Migration of the LWM2M devices in the Protocol integration guide. DM-1866 10.18.0.5 Core
LWM2M A LWM2M device can now completely be deleted from the devices list without an additional clean-up operation. This is done in the same way as any other device is deleted, that is, via the delete icon in the respective row. DM-867 10.17.173.0 UI
LWM2M If event logging is enabled for the LWM2M microservice from the configuration file of the LWM2M agent, the agent now creates new logs as events with detailed information about the reason of failure when a device operation is not executed due to the device connectivity. DM-231 10.17.37.0 Core
OPC UA The OPC UA device gateway can now be run with Thin Edge. The gateway device is automatically created as a child of the Thin Edge device.

Connectivity The performance of MQTT connections has been improved. MQTT devices can now connect or reconnect faster, especially if the platform already has a large number of MQTT devices connected. MTM-53819 10.18.0.113 Core
Device management In the Device profiles page, when adding a repository item (software, firmware, configuration) if the device profile has a device type defined, the items shown either correspond to this device type or they don't have a device type specified. In some cases, repository items without a filter were not visualized in the window for adding an item. These items are now correctly shown. DM-2547 10.18.0.118 UI

Device management In device list views, when a device was deleted, any related child devices were deleted as well. This functionality has now been enhanced. On device deletion, any existing child hierarchy types, that is, not only devices but also additions and assets are deleted accordingly. DM-2003 10.17.73.0 UI
Device management The Assign devices button is now disabled for users without the required permissions. MTM-50928 10.17.16.0 UI
Loriot The memory limit for the Loriot microservice has been increased to 2Gi. DM-2427 10.18.0.74 Core
Loriot Events created by the Loriot agent when sending uplink requests are now considered device requests and provide connectivity status and availability monitoring. DM-2139 10.17.170.0 Core
LWM2M A fail-safe mechanism to regularly get pending LWM2M device connector operations from the platform has been added in addition to the real-time mechanism in the LWM2M agent. This mechanism is beneficial when real-time connections between the LWM2M agent and the platform are unstable. DM-2652 10.18.0.170 Core
LWM2M During a large number of parallel LWM2M DTLS device connection requests, used for devices using PSK secured mode, the LWM2M agent was not able to handle all connections at the same time. This caused platform connection failures for the devices. In the LWM2M agent, the default settings for this part have been adjusted and made configurable to serve large parallel connections. DM-2651 10.18.0.162 Core
LWM2M When reading an entire LWM2M object which contains multiple object instances, in a simple read observer or send operation, the LWM2M agent processed and stored only one of the resources of these object instances. This is now resolved and the LWM2M agent processes and stores all resource data from multiple object instances correctly. DM-2426 10.18.0.155 Core
LWM2M If the LWM2M device observation frequency is high, for example, a few milliseconds, the LWM2M Agent processed the same message multiple times, occupying a lot of resources. This is now resolved. The LWM2M agent no longer reprocesses the same observation request. DM-1823 10.18.0.141 Core
LWM2M The LWM2M agent now correctly persists all registration update parameters. Previously, the LWM2M agent did not store changes of registration parameters, for example, updated registration lifetimes. This is now fixed. DM-2503 10.18.0.129 Core
LWM2M Custom actions were not always executed if a LWM2M device used a SEND operation to report the whole LWM2M object data. This issue is now resolved and the custom actions are always executed for the resource instances for which they are defined. DM-2188 10.18.0.57 Core
LWM2M Bulk device registrations and other operations being executed on the LWM2M connector device now show the status FAILED if a problem occurs. Prior to this change, partial failures were reported as SUCCESSFUL. DM-1951 10.18.0.54 Core
LWM2M In certain cases, the registration couldn't be associated with a LWM2M 1.1 SEND request, leading to a 4.04 CoAP response. This is now fixed. DM-2270 10.18.0.47 Core
LWM2M The LWM2M agent now ignores trailing commas at the end of object links in the registration request of a LWM2M client. DM-2342 10.18.0.46 Core
LWM2M The LWM2M agent is now able to properly convert the timestamps from the SenML data reported by the LWM2M client to a platform compatible date-time format for performing respective resource actions. DM-2150 10.18.0.43 Core
LWM2M Multi-line LWM2M post-operations were not executed right after the LWM2M device's new registration when realtime was disabled for the tenant who owns the device. As a result the device might not receive these operations until the next LWM2M device's registration update. This issue is now resolved and LWM2M post-operations are executed right after the LWM2M device's new registration, no matter whether realtime is enabled or not for this kind of devices. DM-2100 10.18.0.37 Core
LWM2M Two new LWM2M shell commands have been added.
- The new executelegacy command allows LWM2M execute requests with non-standard LWM2M parameters. The behavior of this operation resembles the semantics of the existing execute operation until version 10.15.
- The new coap shell command enables making raw CoAP requests to devices to facilitate non-standard communication in exceptional cases.
For details, refer to LWM2M > Handling LWM2M shell commands in the Protocol integration guide.
DM-2153 10.18.0.6 Core
LWM2M In the Device objects tab, an issue with entering a parameter in the Execute with parameters field has been resolved. DM-2160 10.17.226.0 UI
LWM2M The LWM2M agent now ensures that a LWM2M client registration is expired and removed from the database if the LWM2M client does not update its registration within the respective registration lifetime period. DM-1895 10.17.190.0 Core
LWM2M During the LWM2M client registration, if the agent failed to find the registered device from the database due to a communication problem, an internal object related to the device managed object was automatically removed by the agent. Afterwards, LWM2M clients always failed to connect. This is now fixed and the internal object is only removed if the actual device managed object does not exist in the database. DM-2131 10.17.178.0 Core
LWM2M The LWM2M device type can freely be chosen by the user. Therefore, devices which do not have the type "c8y_lwm2m" but still are LWM2M devices now also show the LWM2M bootstrap parameters view. DM-2066 10.17.171.0 UI
LWM2M Due to a limitation of the Leshan library used by the LWM2M agent, only device registration messages were supported where the LWM2M version is attached to the LWM2M object. The LWM2M agent has now been extended to also accept LWM2M registration messages where the LWM2M version is attached to the LWM2M object instance. DM-1893 10.17.169.0 Core
LWM2M In certain cases the migration of LWM2M devices registered on versions before 10.15 reported "Unable to process device" for certain devices. This happened due to adjustments to the device configuration, for example when editing the registration lifetime. With this fix, the migration logic robustness has been improved. DM-2022 10.17.107.0 Core
LWM2M In the older Leshan demo client, the device registration requests for the Cumulocity IoT LWM2M demo device and possibly also some other devices could contain spaces between the core link separators. This was successfully handled by the LWM2M agent 10.14 and below but caused the LWM2M agent 10.15 and above to reject these device requests. Now, the LWM2M server accepts these requests again. The older device registration requests can be processed again. DM-2070 10.17.105.0 Core
LWM2M The Objects tab now correctly displays JSON values in string fields. DM-1973 10.17.47.0 Core
LWM2M The LWM2M agent now provides a better processing rate of the external decoder events by parallelizing their execution. DM-1840 10.17.36.0 Core
OPC UA The endpoint validation happening during the connection to an OPC UA server can now optionally be disabled. This can be done in the gateway configuration by changing the gateway.connectivity.validateDiscoveredEndpoints setting to "false". Alternatively, it can be controlled via the OPC UA server managed object by setting the fragment validateDiscoveredEndpoints to "false". For details, refer to OPC UA in the Protocol integration guide. DM-2425 10.18.0.157 Core
OPC UA The application of OPC UA device protocols was unreliable when there were more than 1000 protocols. This is now fixed. DM-2634 10.18.0.155 Core
OPC UA In OPC UA device gateway nodes, expected but missing information prevented the completion of the address space scan operation. This is now fixed by skipping these nodes and adding an error message in the opcua-device-gateway log files. Additionally, the overall scanning speed has been improved for the full and partial address space scan operations. DM-2365 10.18.0.128 Core
OPC UA In case of bad connectivity or network delay gateway devices could go to a state where they were disconnected. This resulted in operation execution being suspended. This issue is now resolved. DM-2037 10.18.0.30 Core
