# Release Notes for STM32F103RB-Nucleo Applications Copyright 2017 STMicroelectronics
## Update History ### V1.7.0 / 09-October-2018 Main Changes Update stm32f1xx_hal_conf.h files to add support to HAL CAN Legacy Module. ### V1.5.0 / 14-April-2017 Main Changes Update stm32f1xx_hal_conf.h file to be aligned with new conf_template.h Update applications using FreeRTOS to use TIM HW as time base source ### V1.4.0 / 29-April-2016 Main Changes Change license to “Ultimate Liberty”. Update all the system_stm32f1xx.c with new AHBPrescTable and APBPrescTable. ### V1.3.0 / 18-December-2015 Main Changes To ensure the full compatibility of the GPIO interfaces across all the STM32 families, the gpio speed definition have been renamed: GPIO_SPEED_LOW to GPIO_SPEED_FREQ_LOW GPIO_SPEED_MEDIUM to GPIO_SPEED_FREQ_MEDIUM GPIO_SPEED_HIGH to GPIO_SPEED_FREQ_HIGH aliases are created to keep backward compatibility Change the “Liberty” License with the new license “Ultimate Liberty” for the applications. Reduce the default timeout value for the startup of the HSE form 5s to 100ms. Update the Keil projects from V4 to V5. Adapt the SW4STM32 projects to version 1.5.0 of the IDE. ### V1.2.0 / 31-July-2015 Main Changes FreeRTOS: Reduce heap size accordingly to the OS resources used inside the application. A margin of 10% rounded to the upper Kb is used. This permit to significantly reduce the memory usage within the following applications: FreeRTOS_ThreadCreation: Reduced from 15 Kb of heap (RAM) to 2Kb. (FreeRTOSConfig.h/configTOTAL_HEAP_SIZE) For more details about FreeRTOS implementation on STM32Cube, please refer to UM1722 "Developing Applications on STM32Cube with RTOS". Updates linked to middleware version changes: Minor updates to be compliant with FreeRTOS V8.2.1. ### V1.1.0 / 05-June-2015 Main Changes Add support of System Workbench for STM32 (SW4STM32) toolchain ### V1.0.0 / 16-December-2014 Main Changes First official release. ## License Redistribution and use in source and binary forms, with or without modification, are permitted, provided that the following conditions are met: Redistribution of source code must retain the above copyright notice, this list of conditions and the following disclaimer.
