LWM2M The LWM2M agent realtime subscription for device operations now has a limited Time-To-Live (TTL) duration. The default TTL duration is 3 minutes. This setting may be configured on platform level. DM-3067 10.17.0.409 cumulocity
LWM2M The LWM2M agent's registration cleaner reads all the persisted LWM2M client registrations, then filters the registrations which are no longer valid and deletes them. In case of a huge number of LWM2M client registrations the registration cleaner consumes significant amount of memory, which can affect the LWM2M agent performance. With the current improvement, the registration cleaner only reads the LWM2M client registrations for which the registration time exceeds the timeout period. DM-3070 10.17.0.418 cumulocity

Device management Simulators did not use inventory POST/PUT templates properly as they did not specify any ID fields for the object they created/updated. This has now been resolved by adding the corresponding fields ID, External ID and External ID type depending on the SmartREST template used as instruction. DM-2853 10.17.0.376 UI
Device management Previously, when loading measurement charts data, there was a performance issue if the measurement series had no units defined, depending on the total number of measurement records. This issue has been addressed and measurements series now load efficiently regardless of units being defined or not. DM-2785 10.17.0.377 UI

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 10.17.0.278 UI
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 10.17.0.289 Core
LWM2M If thousands of decoder events were pending to be processed, the LWM2M agent tried to process the same event twice in certain cases. As a result, the log file showed confusing SDK exceptions. This has now been fixed. DM-2659 10.17.0.281 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 connection failures for these devices to the platform. In the LWM2M agent, the default settings for this part have been adjusted and made configurable to serve large parallel connections.

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 10.17.0.219 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 10.17.0.264 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 10.17.0.248 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 10.17.0.235 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 10.17.0.264 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 10.17.0.234 Core

Loriot The memory limit for the Loriot microservice has been increased to 2Gi. DM-2427 10.17.0.182 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 10.17.0.81 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 10.17.0.158 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 10.17.0.157 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 10.17.0.156 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 10.17.0.154 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 10.17.0.146 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 10.17.0.127 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 10.17.0.122 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 10.17.0.82 core
LWM2M The LWM2M device type can be freely 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 10.17.0.72 UI
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 10.17.0.47 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 10.17.0.41 Core
LWM2M A new LWM2M device configuration option has been added to control if the persisted values in the Objects tab get removed in case a read, write or observe observation fails. The option is configurable in the new single device registration in the advanced settings or by having the "c8y_GenericUI_retainOldValuesIfError" fragment in the LWM2M device managed object. For details refer to LWM2M > Registering LWM2M devices > Advanced settings in the Protocol integration guide. DM-1560 10.16.246.0 n/a
LWM2M The LWM2M agent now allows users to write binary data to a resource on a device using a shell operation. For more details about the shell command, refer to LWM2M > Handling LWM2M shell commands in the Protocol integration guide. DM-1241 10.16.211.0 n/a
LWM2M By default, the LWM2M object-resource mappings of the Management tenant that are configured using the LWM2M device protocols were not inherited by the subtenants. With this change, the LWM2M object-resource mappings defined in the Management tenant are applied to all its subtenants by default. The default mappings from the Management tenant can also be overwritten by uploading the LWM2M device protocol for the LWM2M object on the subtenant level as described in LWM2M > LWM2M device protocols in the Protocol integration guide. DM-1778 10.16.206.0 n/a
LWM2M While updating the security info for PSK devices in the database, the LWM2M agent internally deleted the old security managed object and created a new one. Due to the asynchronous deletion of managed objects in the Cumulocity IoT platform, the agent intermittently failed to update the security info. With the current changes, the LWM2M agent updates the required security details in the same managed object instead of removing it first. DM-1671 10.16.206.0 n/a
LWM2M - The LWM2M FOTA process now raises an alarm if the observation to the update state resource of object 5 cannot be established.
-All CoAP requests sent to devices and corresponding responses are now consistently logged.
DM-1711 10.16.161.0 n/a
LWM2M The LWM2M agent now fetches a limited number of pending operations if a LWM2M device sends a registration or a registration update. This prevents the LWM2M agent to do a high number of requests to the platform if devices have accumulated lots of pending operations. The limit is defined with a property in the LWM2M agent. DM-1474 10.16.119.0 n/a
LWM2M A security vulnerability CVE-2022-39368 was found in Leshan 2.0.0-M8 and Californium 3.6.0. The dependencies were updated to the latest versions Leshan 2.0.0-M9 and Californium 3.7.0. DM-1734 10.16.114.0 n/a
LWM2M On the Objects tab in the device details, if you select an object containing a timestamp resource, the text box which displays the timestamp now receives the correct timestamp data type and no error message is displayed. DM-1673 10.16.113.0 n/a
LWM2M - The LWM2M agent always retrieved the external decoder events from one month back only. So if an event remained unprocessed over a month, then it wasn't processed anymore. The time period is now configurable from the agent's configuration.
- Events, measurements, and alarms created by the LWM2M agent are flushed every 10 mins. If a high number of devices connects concurrently or in a short time period, the size of the queue can increase significantly, which in turn leads to high memory usage until all elements are flushed. The flush time interval can now be configured from the agent's properties.
DM-1602 10.16.12.0 n/a
OPC UA If the namespace is not defined for a specific node, a missing error handler in the past prevented completion of the scan operation. This is now fixed by skipping nodes that cannot be read. The opcua-device-gateway logs include further details in such cases. The log level INFO contains the failure message and the log level DEBUG contains the stacktrace. DM-1920 10.17.0.166 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 10.17.0.142 Core
OPC UA On editing the OPC UA device details, the data reporting value is now always saved properly. DM-1668 10.16.102.0 n/a

OPC UA Due to a change introduced in 10.14, the opcua-device-gateway on OPC UA server connects or reconnects did a full device type matching with a comparison of device types to the server's address space to find matched nodes and the application of these matched nodes. With this fix, the opcua-device-gateway directly applies the matched nodes settings if there was a matching done previously and no more recent updates to the device types were done.
