+*** ChibiOS next Release Notes.                                            ***

+******************************************************************************

+

+ChibiOS next is composed of several independent but inter-operable

+sub-projects: RT, NIL, SB, HAL, EX. Plus several external libraries

+integrated in our structure: WolfSSL, FatFS and lwIP.

+

+*** ChibiOS next highlights ****

+

+- New NIL 4.0.

+- New ARM SandBox subsystem.

+- New modules in OSLIB.

+- Support for STM32G0xx and STM32G4xx.

+- Support for all STM32 timers in all drivers.

+- Improved support for all STM32s.

+- Improved MFS module.

+

+*** ChibiOS next general improvements ***

+

+- Lots of style fixes thanks to the new code checker tool.

+- Improved syscalls.c support.

+- Updated FatFS to version 0.13c.

+- Updated lwIP to version 2.1.2.

+- Updated WolfSSL to latest version.

+- Added support for .cc files extensions in makefiles.

+

+*** What's new in RT/NIL ports ***

+

+- Added support for a syscall entry point, it is used by the new ChibiOS/SB

+  subsystem.

+

+*** What's new in OS Library 1.2.0 ***

+

+- Improved OSLIB initialization.

+- Modified core allocator to be able to get blocks starting from bottom

+  or top of the available memory range.

+- Re-introduced missing chGuardedPoolGetCounterI() function to guarded

+  pools allocator.

+- Added a cache class to OSLIB (experimental).

+- Added support for delegate threads.

+- Added support for asynchronous jobs queues.

+

+*** What's new in SB 1.0.0 ***

+

+- New sandbox subsystem. It allows to have untrusted/unreliable code to

+  be run into one or more isolated enclaves (experimental).

+  - Currently only GCC is supported.

+  

+*** What's new in RT 6.1.0 ***

+

+- Added a "library generator" project for RT, it allows to

+  generate a library with a pre-configured RT. It also includes

+  an "header generator" able to generate an unified "ch.h" with

+  all options resolved.

+- New functions: chSemResetWithMessageI() and chSemResetWithMessage().

+- Improvements to messages, new functions chMsgWaitS(), chMsgWaitTimeoutS(),

+  chMsgWaitTimeout(), chMsgPollS(), chMsgPoll().

+

+*** What's new in NIL 4.0.0 ***

+

+- New NIL 4.

+  - Increased API compatibility with RT.

+  - Full threading (create, wait, exit).

+  - Events support like in RT (optional).

+  - Messages support like in RT (optional).

+  - Full OSLIB support.

+- New functions: chSemResetWithMessageI() and chSemResetWithMessage().

+- Improvements to messages, new functions chMsgWaitS(),

+  chMsgWaitTimeoutS(), chMsgWaitTimeout().

+

+*** What's new in HAL 7.1.0 ***

+

+- Added a new interface for range-finder devices.

+- Added transactional updates to MFS. Doubled data headers magic numbers

+  for improved safety and to keep the final write aligned to 64 bits.

+- Modified AES GCM function signatures.

+- Added and embedded flash driver model in HAL. Added an implementation

+  for STM32F1xx, STM32L4xx, STM32L4xx+. 

+- Modified the ST driver to support, optionally, multiple additional

+  callback-capable channels.

+- Added error handling to WSPI driver, now LLDs can report error

+  conditions to upper layers.

+- Added canTryAbortX() function to CAN driver, implemented

+  for STM32 CANv1.

+       

+*** What's new in EX 1.1.0 ***

+

+

+*** What's new in AVR HAL support ***

+

+

+*** What's new in STM32 HAL support ***

+

+- Added support for STM32G0xx.

+- Added support for STM32G4xx.

+- Added support for ADuCM36x.

+- Improved DMAv1 and DMAv2 drivers.

+- TRNG support added to STM32F7xx, STM32G0xx, STM32G4xx, STM32H7xx and

+  STM32L0xx.

+- Idle callback support for STM32 USARTv1 UART driver.

+- Improved support for shared handlers. Now there are centralized

+  inclusion modules (.inc) containing shared handlers. The new modules

+  can be included by the various STM32 platforms. So far the new system

+  has been implemented for STM32G0, STM32G4, STM32L0, STM32L4, STM32L4+,

+  STM32F7, STM3277.

+- Added support for timers 9..17, 20..22 to STM32 PWM driver.

+- Added support for timers 9..17, 20..22 to STM32 ICU driver.

+- Added support for timers 10 and 13 to STM32 GPT driver.

+- Added support for timers 9..14 to STM32 ST driver.

+- PAL, SERIAL and SPI support added to ADuCM36x.

+

+*** What's new in tools ***

+

+- Code style checker tool added.

+- Introduced mcuconf.h updater tool for STM32F407, STM32L052/L053/L062/L063,

+  STM32L072/L073, STM32G4x1/G4x3/G4x4.

+- Added script to generate board files from command line, just

+  run ./os/hal/boards/genboard.sh with the board directory name

+  as parameter.
