Important Changes
-----------------

New Watchdog API:

Continuing the Zephyr Long Term Support (LTS) goal of having stable driver
APIs, the watchdog.h interface was overhauled and re-worked. The
wdt_enable(), wdt_get_config(), wdt_set_config() and
wdt_api_reload() routines are still around for now, but have been
deprecated. Users of the watchdog API will want to switch to the new
routines documented in include/watchdog.h instead.

A driver using the new API was merged for the nRF SoC family's watchdog
peripheral. This driver uses device tree.

Menuconfig is now in Python:

The previously experimental Python menuconfig implementation has replaced
the C tools, following the addition of symbol search and jump-to-definition
features.

Users who were building the C tools in order to run menuconfig must use
the new Python tools instead. Windows users need to install a new
dependency via pip (by re-running "pip3 install -r
scripts/requirements.txt") before using this program. Mac and Linux users
do not require any additional dependencies.

Zephyr's use of Kconfig includes additional features not present in
the language implemented by the C tools. Somewhat confusingly,
documentation for these features was added to the board porting guide:

http://docs.zephyrproject.org/porting/board_porting.html#kconfig-extensions

This is a significant change, in that it now makes Zephyr development
possible on Windows in the native cmd.exe or Powershell shells, without any
additional Unix-specific toolchains or environments.

Storage API changes:

A variety of storage-related API changes were merged. These mostly are used
to enable new features.

The Kconfig knob which enables the storage_partition flash partition
(see http://docs.zephyrproject.org/devices/dts/flash_partitions.html)
was renamed from CONFIG_FS_FLASH_MAP_STORAGE to
CONFIG_FS_FLASH_STORAGE_PARTITION. This rename was done because use of
the storage partition does not require the flash_map module.

The filesystem API's struct fs_mount_t can now store references to
storage devices of arbitrary type in its storage_dev field; it was
previously restricted to a struct device*, but is now a void*. This
change was made to enable additional layers of indirection between this
field and the backing device.

The disk_access.h API was modified to support simultaneous use of multiple
disk interfaces. The old disk_access_ram.c and disk_access_flash.c have
seen a corresponding refactor; their globally available functions are now
hidden behind instances of the new struct disk_info and struct
disk_operations structures introduced in this change. The external FAT
file system library now supports multiple volumes.

The filesystem subsystem now supports multiple mounted instances of a
filesystem. As a result of these changes, the fs/fs_interface.h API no
longer assumes that either FAT or NFFS file systems are being used.

Bluetooth bt_storage removed in favor of settings API:

The bt_storage API was removed, as it provided features now enabled by the
settings subsystem using CONFIG_BT_SETTINGS. Users of this API will need
updates.

The Bluetooth shell and mesh and mesh_demo samples now have settings
support, as demonstrations of using the API.

Bluetooth Mesh support for the settings API required some refactoring to
expose previously hidden symbols to the storage API. There are some
tradeoffs, particularly related to managing flash wear when storing the
local sequence number and replay protection list; refer to the help for the
new CONFIG_BT_MESH_SEQ_STORE_RATE and BT_MESH_RPL_STORE_TIMEOUT options
for details.

Using this API requires a larger system workqueue stack size; the present
recommended size when using this API is now 2 KB, double its default value.

One additional alternative to using the settings API is the new
bt_set_id_addr() routine, which allows applications to set their identity
addresses in a manner similar to the bt_settings API.

Features
--------

Arches:

ARMv8-M MCUs with the Main Extension now have support for hardware-based
main stack overflow protection. The relevant Kconfig option to enable the
feature is CONFIG_BUILTIN_STACK_GUARD.

x86 CPUs can now grant user space access to the heap when using the newlib
C library.

Documentation:

In something of a "meta" development, documentation was added for how
to write Zephyr documentation:

http://docs.zephyrproject.org/contribute/doc-guidelines.html

Drivers and Device Tree:

The YAML device tree bindings for SPI now include an optional cs-gpios
property, which can be used to generate GPIO chip select definitions.

The bindings for ST's SPI-based BTLE nodes now require irq-gpios and
reset-gpios properties. The names of such devices are now only present in
Kconfig if a new CONFIG_HAS_DTS_SPI_PINS selector is unset.

There are two new Kconfig symbols, CONFIG_HAS_DTS_GPIO and
CONFIG_HAS_DTS_GPIO_DEVICE, which respectively allow declaring that the
GPIO driver supports device tree, and that drivers which need GPIOs do as
well. Currently, only the STM32 and MCUX GPIO drivers select
CONFIG_HAS_DTS_GPIO.

DT-based GPIO support for the NXP i.MX7 M4 SoC was added.

The mcux DSPI driver now uses device tree; SPI bindings were added to the
SoC files appropriately to enable this change. This driver also now
supports KW40/41Z SoCs.

The LED driver subsystem now has system call handlers for user mode
configurations.

The USB device controller driver for STM32 devices now supports all STM32
families, among a variety of other improvements to enable USB support on
STM32 MCUs in a variety of families. Board support was also added for
olimexino_stm32 and stm32f3_disco.

The pinmux subsystem no longer supports user mode access. This subsystem's
drivers lack sufficient input validation to prevent a malicious userspace
from accessing unauthorized memory through API calls. A proper fix will
require developing a specification for the subsystem, and updating existing
drivers to do appropriate input validation.

Altera HAL drivers can now be run on Zephyr. Such a driver for the Nios-II
modular scatter-gather DMA (mSGDMA) peripheral was merged, from the Altera
SDK v17. This was used to add a shim driver using Zephyr's dma.h API.

Networking:

The LWM2M implementation was significantly refactored and cleaned up. Once
nice benefit of this work is a 3KB RAM savings when running an LWM2M
client.

The network interface core now supports net_if_ipv4_select_src_addr() and
net_if_ipv4_get_ll() routines for accessing IPv4 source addresses.

Each struct net_pkt now uses one less byte of space, thanks to an
optimization in the size of its _unused field.

Testing:

The test case documentation now describes best practices for developing a
test suite, and how to list and skip test cases; see
http://docs.zephyrproject.org/subsystems/test/ztest.html for details.

Various tests were converted to use the ztest API, along with other
cleanups, renames, and Doxygen fixups added to the test suite.

Bug Fixes
---------

A build issue on sam_e70 was fixed.

An off-by-one error in the ARM MPU buffer validation routine was fixed.

A dedicated routine for incrementing the sequence number in the Bluetooth
Mesh implementation was added; in addition to fixing race conditions, this
is used by Mesh's settings subsystem integration in order to persist
sequence numbers to flash.

A Bluetooth Mesh bug affecting sequence number calculation in the Friend
queue was fixed.

Fixes to the TI ADC108S102 driver; VL53L0X, LSM6DSL, and HTS221 sensor
drivers; and QMSI UART driver were merged.

Fixes for using the FXOS8700, FXAS21002, and MCR20A drivers on NXP SoCs
were merged.

User mode heap access was fixed for applications which use the newlib C
library. User mode applications also no longer allow the stack sentinel
debugging feature to be enabled. This change was made because
CONFIG_USERSPACE implies separate and more robust stack protection
mechanisms.

The networking traffic class map from packet priorities to traffic classes
was fixed to comply with the IEEE 802.1Q specification.

The websocket implementation was refactored to avoid unnecessary tricky
calculations, resolving Coverity warnings.

The http_client sample was fixed in cases when TLS is enabled; previously,
this application overflowed a stack in this use case.

The mcumgr smp_svr sample's build was fixed.

The echo_server sample works on CC2520 again, along with other improvements
on that board. The CC3220sf board's linker map was also fixed.

The echo_server sample works on frdm_kw41z again, after other changes went
in that caused a stack overflow.

Various fixes and refactoring patches were merged to the
extract_dts_includes.py script, which generates code used by Zephyr from
the final device tree produced during an application build.
