# Release Notes for STM32L1xx_Nucleo Board Drivers Copyright 2017 STMicroelectronics
## Contents STM32L1xx_Nucleo Board Drivers update History License ## STM32L1xx_Nucleo Board Drivers update History ### V1.1.2 / 25- August-2017 Main Changes Removed DATE and VERSION fields from header files. Updated CHM User Manual for BSP/STM32L1xx_Nucleo. ### V1.1.1 / 21-April-2017 Main Changes Updated CHM User Manual for BSP/STM32L1xx_Nucleo. ### V1.1.0 / 04-March-2016 Main Changes Rewrite driver to support 4 Gb micro sd card. Add functions BSP_LED_DeInit BSP_PB_DeInit BSP_JOY_DeInit ### V1.0.2 / 09-October-2015 Main Changes Added aliases to use either BUTTON_USER or BUTTON_KEY. The polling of ADC is improved inside BSP_JOY_GetState function. The LED GPIO is set to GPIO_NOPULL instead of GPIO_PULLUP to improve the power consumption. Added check on parameter given to LEDx_GPIO_CLK_ENABLE(__LED__) LEDx_GPIO_CLK_DISABLE(__LED__) BUTTONx_GPIO_CLK_ENABLE(__BUTTON__) BUTTONx_GPIO_CLK_DISABLE(__BUTTON__) Compatibility: Due to changes in the gpio speed definition, this version requires STM32L1xx_HAL_Driver V1.1.2 ### V1.0.1 / 31-March-2015 Main Changes Alignment to latest changes done on HAL driver. ### V1.0.0 / 05-September-2014 Main Changes First official release dedicated to STM32CubeL1 based development.
