Messages now use a new field into the p_u union. Now synchronous messages are even faster. - HAL: Fixed typos in STM32F0 RCC enable/disable macros (bug #698)(backported to 16.1.2). - RT: Fixed useless call to chTMStartMeasurementX() in _thread_init() (bug #697)(backported to 3.0.6 and 16.1.3). - VAR: Fixed missing time conversion in lwIP arch module (bug #696) (backported to 2.6.10, 3.0.5 and 16.1.2). - HAL: Fixed incorrect handling of TIME_IMMEDIATE in the HAL buffer queues (bug #695)(backported to 16.1.2). - NIL: Fixed NIL_CFG_USE_EVENTS not properly checked in NIL (bug #694) (backported to 3.0.5 and 16.1.1). - RT: Fixed ISR statistics are not updated from a critical zone in RT (bug #693)(backported to 3.0.5 and 16.1.1). - NIL: Fixed NIL test suite calls I and S functions outside critical zone (bug #692)(backported to 3.0.5 and 16.1.1). - NIL: Fixed protocol violation in NIL OSAL (bug #691)(backported to 3.0.5 and 16.1.1). - HAL: Fixed error in HAL buffer queues (bug #689)(backported to 16.1.1). - RT: Fixed tm_stop - best case bug (bug #688)(backported to 16.1.1 and 3.0.5). - ALL: Several minor documentation/formatting-related fixes. *** 16.1.0 *** - RT: Added CodeWarrior compiler support to the e200 port. - HAL: Added support for STM32F446. - HAL: Introduced preliminary support for STM32F7xx devices. - HAL: Introduced preliminary support for STM32L4xx devices. - HAL: Introduced preliminary support for STM32L0xx devices. - HAL: Increased performance of USBv1 and OTGv1 driver thanks to better data copying code. - HAL: Enhanced Serial-USB driver using the new buffers queues object. - HAL: Simplified USB driver, queued API has been removed. - HAL: Enhanced the CAN driver with I-class functions. Now it is possible to exchange frames from ISRs. - HAL: Added watchdog driver model (WDG) and STM32 implementation on IWDG. - HAL: Added synchronous API and mutual exclusion to the UART driver. - HAL: Added PAL driver for STM32L4xx GPIOv3 peripheral. - HAL: Added I2S driver for STM32 SPIv2 peripheral. - HAL: Added demos an- d board files for ST's Nucleo32 boards (F031, F042, F303). - HAL: Added "lines" handling to PAL driver, lines are identifiers of both ports and pins encoded in a single value.
