*****************************************************************************

*** Next ***
- NEW: Added a new MEM_IS_VALID_FUNCTION() macro to RT and NIL.
- NEW: Improved HAL flash interface with mutual exclusion methods, improved
       EFL and SNOR drivers to use it.
- NEW: Added a centralized errors handler under /os/common/utils. It will
       replace those in HAL and SB and will be shared among multiple subsystems.
- NEW: Added a new OOP model under /os/common/utils. It will replace the
       one in HAL and will be shared among multiple subsystems.
- NEW: Changed SB configuration options names to be prefixed with SB_CFG_.
- NEW: Added a new CH_CFG_HARDENING_LEVEL option to RT.
- NEW: Added a chXXXDispose() function to all objects in NIL.
- NEW: Added a chXXXDispose() function to all objects in RT.
- NEW: Added VFS-related commands to the shell, disabled by default.
- NEW: Added a new VFS subsystem (Virtual File System), it allows to assemble
       trees of files from multiple "File System Drivers" into a single tree
       and access it as a whole.
- NEW: Added MEM_NATURAL_ALIGN macro to RT and NIL.
- NEW: Added static initializer for virtual timers in RT.
- NEW: Added new function chHeapIntegrityCheck().
- NEW: Added EFL driver implementation for STM32G4xx.
- NEW: Function chCoreGetStatusX() changed to return a memory region object
       instead of a simple size.
- NEW: RT and NIL upgraded to support the enhanced OSLIB.
- NEW: Memory areas/pointers checker functions added to OSLIB.
- NEW: STM32G0B1 USBv2 driver.
- NEW: USBv1 driver optimization and removal of a potential race condition
       (not demonstrated).
- NEW: Added elfAcquireBus()/eflReleaseBus() functions to EFL driver.
- NEW: Increased stacks size in RT test suite from 128 to 192. added an
       option to override the stack size by defining THREADS_STACK_SIZE
       in the makefile.
- NEW: Added STM32L073RZ-Nucleo64 to USB-CDC "multi" demo. Removed old demo.
- NEW: Added an STM32 WDG "multi" demo. Removed all old WDG demos.
- NEW: Added option to copy vectors in RAM on GCC startup for ARMv6-M,
       ARMv7-M and ARMv8-M-ML.
- NEW: On STM32WBxx added a check on STM32_LSI_ENABLE required by IWDG.
- NEW: Added SPIv2 support also to STM32WB and STM32WL.
- FIX: Fixed missing check in chobjcaches.h (bug #1210)
       (backported to 20.3.5)(backported to 21.11.2).
- FIX: Fixed misspelled chTraceSuspendI() function name (bug #1209)
       (backported to 21.11.2).
- FIX: Fixed RT testbuild application broken (bug #1208)
       (backported to 20.3.5)(backported to 21.11.2).
- FIX: Fixed PWR_CR2_USV not set in STM32L4+ mcuconf.h file (bug #1207)
       (backported to 21.11.1).
- FIX: Fixed USB not enabled on STM32F103x6 (bug #1206)
       (backported to 20.3.5)(backported to 21.11.1).
- FIX: Fixed RT test suite build fails when CH_CFG_USE_TIMESTAMP is FALSE
       (bug #1205)(backported to 21.11.1).
- FIX: Fixed wrong number of CAN filters for STM32L496/9A6 (bug #1204)
       (backported to 20.3.5)(backported to 21.11.1).
- FIX: Fixed DMA stream not disabled in STM32 QUADSPIv1 driver (bug #1203)
       (backported to 20.3.5)(backported to 21.11.1).
- FIX: Fixed I2C4 DMA streams for STM32L496 (bug #1202)
       (backported to 20.3.5)(backported to 21.11.1).
- FIX: Fixed STM32_SDMMC2_NUMBER on STM32H7 (bug #1201)
       (backported to 20.3.5)(backported to 21.11.1).
- FIX: Fixed STM32G0B1 demo application hangs debuggers (bug #1200)
