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

• Our C++ header files changed their extension from *.h* to *.hpp* in version 0.7.0, Intel provided examples and code samples also reflect this change but you will need to modify your #include directives in existing code
• 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
