+* Made these global changes in STM32 boards and SoC series:
+
+  * Pin control configuration is now done through device tree and existing
+    macros to configure pins in pinmux.c files are tagged as deprecated.
+    The new pin settings are provided thanks to .dtsi files distributed in
+    hal_stm32 module.
+  * Generic LL headers, also distributed in hal_stm32 module, are now available
+    to abstract series references in drivers.
+  * Hardware stack protection is now default on all boards with enabled MPU
+    (SRAM > 64K ), excluding F0/G0/L0 series.
+  * West flash STM32CubeProgrammer runner was added as a new option for STM32
+    boards flashing (to be installed separately).
+
 * Made these changes in other boards:
 
   * CY8CKIT_062_WIFI_BT_M0: was renamed to CY8CKIT_062_WIFI_BT.
