*** 19.1.3 ***
- NEW: 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.
- FIX: Fixed missing bracket in MX25 flash driver (bug #1038).
- FIX: Fixed some M7 demos compile as M4 bug #1037).
- FIX: Fixed missing I2C4 RCC definitions for L4/L4+ (bug #1036).
- FIX: Fixed missing delay after STM32 wait states setup (bug #1035).
- FIX: Fixed reduced time slices in RT (bug #1034).
- FIX: Fixed GCC scatter files alignment problem (bug #1033).
- FIX: Fixed long intervals fail when interval type is larger than time type
       (bug #1031).
- FIX: Fixed Round Robin check missing when in tick-less mode (bug #1030).
- FIX: Fixed RCC_AHB1ENR_BKPSRAMEN not present in all STMF4xx devices
       (bug #1029).
- FIX: Fixed MPU fix #1027 broke stack checking on Cortex-M devices without
       MPU (bug #1028).

*** 19.1.2 ***
- NEW: Modified AES GCM function signatures.
- NEW: updates to MFS from trunk code.
- NEW: updates to test library from trunk code.
- HAL: Added H753 to all H7 mcuconf.h files.
- FIX: Fixed MPU setup missing on thread start (bug #1027).
- FIX: Fixed invalid I2C4 DMAs for STM32F76x (bug #1026).
- FIX: Fixed invalid STM32_UART7_RX_DMA_CHN for STM32F469 (bug #1025).
- FIX: Fixed invalid EXTI registry constant for STM32L4+ (bug #1024).
- FIX: Fixed missing RTC definitions in STM32L1xx registry (bug #1023).
- FIX: Fixed missing EXTI driver integration on some platforms (bug #1022).

*** 19.1.1 ***
- LIB: Re-introduced missing chGuardedPoolGetCounterI() function to guarded
       pools allocator.
- NEW: Extra timer checks in STM32 ST driver.
- FIX: Fixed various UART clock naming errors in STM32H7 HAL (bug #1021).
- FIX: Fixed missing STM32L4+ check in GPIOv3 driver (bug #1020).
- FIX: Fixed call to obsolete dmaStreamRelease() in STM32 I2Cv3 driver
       (bug #1019).
- FIX: Fixed misconfiguration in STM32L4R9I DIscovery board files (bug #1018).
- FIX: Fixed wrong Debug launch configuration in STM32L4Rx demos (bug #1017).
- FIX: Fixed wrong ADCSEL definitions in STM32H7 HAL (bug #1016).
- FIX: Fixed chTimeIsInRangeX() failing under some configurations (bug #1015).
- FIX: Fixed invalid AXI errata fix for STM32H7xx (bug #1014).
- FIX: Fixed invalid ADCD3 initialization in STM32 ADCv3 driver (bug #1013).
- FIX: Fixed invalid call to dmaStreamRelease() in STM32 SDIOv1 driver
       (bug #1012).
- FIX: Fixed wrong license restriction check in Nil (bug #1011).
- FIX: Fixed uninitialized variables in STM32 DMA drivers (bug #1010).
- FIX: Fixed wrong mcuconf.h in some testex demos related to STM32F407 
       (bug #1008).
- FIX: Fixed problem in STM32 mcuconf.h template files (bug #1007).
- EX:  Fixed I2C Acquire bus called twice in the HTS221 initialization 
       (bug #1006).
- EX:  Fixed missing I2C release bus in LPS22HB initialization (bug #1005).
