Highlights:

• There are some breaking changes, so please read the Release Notes carefully before updating.
• pvlib now has a new Array class that represents groups of identical modules that are part of a PVSystem but have the same orientation and mounting type.
• The PVSystem class can now model a combination of arrays each with different orientations, modules, and mounting types.
• pvlib completed a very successful GSoC, which added several new iotools like get_bsrn(), get_pvgis_hourly(), get_cams(), and more. Special thanks to Adam R. Jensen, Kevin Anderson, and many reviewers who helped!
• Many bug fixes including a fix to Perez contributed by Clean Power Research. Read their blog to learn more about how they're contributing to pvlib. Thanks!
