IMPORTANT NOTICE

Our C++ header files will change their extension from *.h* to *.hpp*. This change is anticipated in the upcoming version and unfortunately will break source compatibility with previous versions of UPM for every library. You will need to update your code and change to the new extension format in your #include directives.

Here's a list of other API changes made to the library that break source/binary compatibility between releases:

• my9221, groveledbar and grovecircularled are now all part of the same library (my9221) and new functionality was added going to v.0.5.1
• stepmotor driver API was changed significantly from v.0.4.1 to v.0.5.0
• eboled library was greatly improved in version 0.4.0 and the draw() function was removed in favor of a more complete GFX library implementation
