Replace function parameter 'retries' with pointer to structure holding coap transmission parameters. This allows setting the retransmission parameters individually for each pending request. Add coap transmission parameters to coap_pending structure. Update migration guide and release notes. Signed-off-by: Juha Ylinen <juha.ylinen@nordicsemi.no>

Boards & SoC Support
|
|
********************
|
|
|
|
* Added support for these SoC series:
|
|
|
|
* Added support for Renesas R-Car Gen4 series
|
|
|
|

|
|
|
|
* Made these changes in other SoC series:
|
|
|
|
* Nordic SoCs now imply :kconfig:option:`CONFIG_XIP` instead of selecting it, this allows for
|
|
creating RAM-based applicatins by disabling it.
|
|

Build system and infrastructure
|
|
*******************************
|
|
|
|
* Dropped the ``COMPAT_INCLUDES`` option, it was unused since 3.0.
|
|
|
|
* Fixed an issue whereby board revision ``0`` did not include overlay files for that revision.
|
|
|
|
* Added ``PRE_IMAGE_CMAKE`` and ``POST_IMAGE_CMAKE`` hooks to sysbuild modules, which allows for
|
|
modules to run code after and before each image's cmake invocation.
|
|
|
|
* Added :kconfig:option:`CONFIG_ROM_END_OFFSET` option which allows reducing the size of an image,
|
|
this is intended for use with firmware signing scripts which add additional data to the end of
|
|
images outside of the build itself.
|
|
|
|
* Added MCUboot image size reduction to sysbuild images which include MCUboot which prevents
|
|
issues with building firmware images that are too large for MCUboot to swap.

|
:c:func:`setsockopt` API.
|
|
|
|

|
|
:c:macro:`NET_MGMT_REGISTER_EVENT_HANDLER`.
|

**********************
|
|
|
|
* Management
|
|
|
|
* Fixed an issue in MCUmgr image management whereby erasing an already erased slot would return
|
|
an unknown error, it now returns success.
|
|
|
|
* Fixed MCUmgr UDP transport structs being statically initialised, this results in about a
|
|
~5KiB flash saving.
|
|
|
|
* Fixed an issue in MCUmgr which would cause a user data buffer overflow if the UDP transport was
|
|
enabled on IPv4 only but IPv6 support was enabled in the kernel.
|
|
|
|
* Implemented datetime functionality in MCUmgr OS management group, this makes use of the RTC
|
|
driver API.
|
|
|
|
* Fixed an issue in MCUmgr console UART input whereby the FIFO would be read outside of an ISR,
|
|
which is not supported in the next USB stack.
|
|
|
|
* Fixed an issue whereby the ``mcuboot erase`` DFU shell command could be used to erase the
|
|
MCUboot or currently running application slot.
|
|
|
|
* File systems
|
|
|
|
* Modem modules
|
|
|
|
* Power management
|
|
|
|
* Random
|
|
|
|
* Retention
|
|
|
|
* Fixed issue whereby :kconfig:option:`CONFIG_RETENTION_BUFFER_SIZE` values over 256 would cause
|
|
an infinite loop due to use of 8-bit variables.
|
|
|
|
* Binary descriptors
|

|
* POSIX API

* CAN ISO-TP
|

|
* RTIO
|
|
|

|

* Renamed :kconfig:option:`ZBUS_MSG_SUBSCRIBER_NET_BUF_DYNAMIC` and
|
|
:kconfig:option:`ZBUS_MSG_SUBSCRIBER_NET_BUF_STATIC`
|
|
with :kconfig:option:`ZBUS_MSG_SUBSCRIBER_BUF_ALLOC_DYNAMIC` and
|
|
:kconfig:option:`ZBUS_MSG_SUBSCRIBER_BUF_ALLOC_STATIC`

Tests and Samples
|
|
*****************
|
|
|
|
* :ref:`native_sim<native_sim>` has replaced :ref:`native_posix<native_posix>` as the default
|
|
test platform.
|
|
:ref:`native_posix<native_posix>` remains supported and used in testing but will be deprecated
|
|
in a future release.
|
|
|
|
* Fixed an issue in :zephyr:code-sample:`smp-svr` sample whereby if USB was already initialised,
|
|
application would fail to boot properly.
