API Changes                       {#apichanges}
===============

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

 * **grove** As of UPM 1.0 the Grove classes for sensors in the starter kit are
 being separated into individual libraries. The old classes will be deprecated
 over time and eventually removed. Corresponding libraries have the grove
 prefix removed. Affected classes are GroveButton, GroveLed, GroveLight,
 GroveRelay, GroveRotary, GroveSlide and GroveTemp.
 * **grove** Binary compatibility was broken for the GroveTemp class as of UPM
 v0.7.3. C++ samples and code using this class has to be recompiled.
 * The Ublox6 driver has been removed and replaced with a generic
 implementation called nmea_gps.  This driver should handle all
 generic serial GPS devices that output NMEA data going forward.  This
 new driver has been tested with ublox6, DFRobot VK2828U7 (ublox7) and
 ublox LEA-6H GPS devices.
 * There were frequent misspellings of the word *Celsius* in the UPM
 code.  In some cases, these were in method names, which will cause
 some API compatibility issues.  These have all been corrected for UPM
 versions after v.0.7.2.
 * 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
