2.2.0 - First Public Release

First public release of the porch light system. I realize this is pretty specific to the hardware setup I've created, however this can easily be forked, modified, & used for your own lighting system!

There's never been actual version numbering for the porch lights system, so this first version number is based on the following:

• Major = 2

  This is easy, there was an original codebase, the current codebase was written after that from scratch as a complete overhaul

• Minor = 2

  I would consider 0 the initial version, 1 was when the bugs were worked out, 2 is now, where we are completely stable and just got the alternate handrail stair pattern working

• Patch = 0

  I'm considering us as having just entered into minor version 2, so this is 0 to signify that
