FreeRTOS version 8.1.2 versus 9.0.0

Hello, I’m working on a project that use FreeRTOS version 8.1.2 and it seems that the sources have been modified. Unfortunately there is no backup of original sources (v8.1.2). Before switch to a newer version I would like to check diffs against original v8.1.2 sources. Where can I find it. Thanks
