I've just released version 4.0.2 (https://github.com/andysworkshop/stm32plus/releases/tag/4.0.2) of stm32plus. This release collects together a number of bug fixes and small features that have been made since 4.0.0.
There was, briefly, a 4.0.1 release but since I forgot to update the build version number in stm32plus.h (https://github.com/andysworkshop/stm32plus/blob/master/lib/include/config/stm32plus.h) it was quickly abandoned so 4.0.2 is the latest release as of today.
