• https://docs.zephyrproject.org/latest/services/pm/api/index.html?highlight=pm_device_state_suspend#c.pm_device_state.PM_DEVICE_STATE_SUSPENDED

• https://docs.zephyrproject.org/2.6.0/reference/power_management/index.html?highlight=pm_device_state_suspend#c.PM_DEVICE_STATE_SUSPEND

Change to at_cmd.h header file and larger library:

• https://devzone.nordicsemi.com/f/nordic-q-a/87493/at-command-interface-library-removed-in-ncs-1-9-1
• https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.0/nrfxlib/nrf_modem/doc/at_interface.html

Calls to `rstatus = at_cmd_write("AT+CFUN=1", buffer_at_response, sizeof(buffer_at_response), NULL)` must become calls to `int nrf_modem_at_cmd(void *buf, size_t len, const char *fmt, ...);`

Change in power management from Zephyr 2.6.0 to 3.0.99:

ted@localhost:~/projects-sandbox/workspace-hardware-Stage1-firmware/zephyr$ grep -nr pm_device_state_set ./*
./doc/releases/release-notes-2.6.rst:120:  ``pm_device_state_set`` and ``pm_device_state_get`` in order to align with
./doc/releases/release-notes-3.0.rst:794:  * :c:func:`pm_device_state_set` is deprecated in favor of utilizing :c:func:`pm_device_action_run`.

Change in Zephyr 2.6.0 [zephyr_root]/include/net/socket_ncs.h:22:#define AT_LTE PF_LTE /** Address family specific to LTE. */

This Zephyr RTOS change affects the building of Nordic ncs v1.6.1 sample app aws_iot, which contains a file in nrf/boards/arm/nrf9160/board_nonsecure.c. This file references the deprecated symbols AF_LTE and NPROTO_AT. This source file is absent in nrf v2.0.1. References to MAGPIO in the later nrf release appear only in Kconfig files, not the file board_nonsecure.c.
