*** Next ***
- NEW: Added support for LPS22HB 2 axis Barometer\Thermometer MEMS.
- NEW: Separated OSLIB from RT and NIL, now it is a separate "product" with
       its own version, configuration file and licensing. The library will
       grow to include more functionalities.
       RT and NIL will contain only the core functionalities, everything else
       is shared library code.
- HAL: Fixed I2C address not accepted (bug #923)(backported to 18.2.1
       and 17.6.4).
- HAL: Fixed problem with HSI48 on STM32L4xx (bug #922)(backported to 18.2.1).
- HAL: Fixed invalid implementation of palWaitPadTimeoutS() and
       palWaitLineTimeoutS() APIs (bug #921)(backported to 18.2.1).
- HAL: Fixed wrong DMA settings for STM32F76x I2C3 and I2C4 (bug #920)
       (backported to 18.2.1 and 17.6.4).
- HAL: Fixed wrong flash waiting state for STM32F7xx (bug #918)
       (backported to 18.2.1 and 17.6.4).
