Some errors can occur in the sending process that have to be handled
in a polling fasion instead of blocking using semaphores. In this case
apply an exponentially growing backoff time. This will allow for fast
reactions in most situations and prevents high system loads in case
resolving the situation takes a little longer.

The new interface contract guarantees that OpenThread stack uses
otPlatSettingsSet only for aKey which has at most one value at time.
This implies the simplification for key name used by settings subsystem
and decreases the count of records written each time when the value
for specific key is updated. In result non-volatile memory can be used
more efficiently.
It relates to zephyrproject-rtos/openthread commit: ed665e9 .

By default, any string or opaque data that LwM2M engine initializes
sets data lenght to same value as given buffer length for that
resource.
However, on run time, engine keeps track how much data is written
to each resource, so when reading from any resource, should only
return data that has been written there. But uninitialized resources
return the content of the whole buffer.
Fixed the problem by introducing macros INIT_OBJ_RES_LEN(),
INIT_OBJ_RES_MULTI_DATA_LEN() and INIT_OBJ_RES_DATA_LEN() that
allows you to give the amount of data existing in buffer when
the resource is initialized. This sets the data_len and max_data_len
variables correctly.
Also introduced new functions lwm2m_engine_get_res_buf() and
lwm2m_engine_set_res_buf() that distinct between data size and
buffer size. Deprecated the previous functions
lwm2m_engine_get_res_data() and lwm2m_engine_set_res_data()

Fragmented data passed to sendmsg() should be sent as a single datagram in
case of datagram sockets (i.e. DTLS connection). Right now that is not
happening now, as each fragment is sent separately, which works fine only
for stream sockets.
There is no mbedTLS API for 'gather' write at this moment. This means that
implementing sendmsg() would require allocating contiguous memory area at
Zephyr TLS socket level and copying all data fragments before passing to
mbedTLS library. While this might be a good option for future, let's just
check if data passed to sendmsg() API consists of a single memory region
and can be sent using single send request. Return EMSGSIZE error if there
are more then one data fragments.
