+Changes in 1.2
+- Added better error handling
+- Removed forcibly adding a newline to the serial data being sent to the port. This
+  means apps must send in a newline if the serial port expects it.
+- Embedded the home.html file inside the binary so there is no longer a dependency
+  on an external file.
+- TODO: Closing a port on Beagle Bone seems to hang. Only solution now is to kill
+  the process and restart.
+- TODO: Mac implementation seems to have trouble on writing data after a while. Mac
+  gray screen of death can appear. Mac version uses CGO, so it is in unsafe mode.
+  May have to rework Mac serial port to use pure golang code.
