Arduino for STM32

Hello, I found a list of supported STM32 at https://github.com/stm32duino/Arduino_Core_STM32/. However, I'm wondering what the difference is in support and capabilities for the Nucleo F303RE? The table lists the Nucleo have release as 0.1.0, while the STM32F303RE generic board have release is 2.0.0. What's the difference between 0.1.0 and 2.0.0?

it's a version of stm32duino from which each MCU/board is supported.
