Version 3.5.0 (https://github.com/andysworkshop/stm32plus/releases/tag/3.5.0) of stm32plus has now been released.
Please do take the time to review the linked release notes because there is a runtime breaking change for projects that have been built against previous releases. I know breaking changes are painful but this one is quite trivial to fix and does enable integration with other frameworks and RTOS systems.
