Features

~~~~~~~~



- Turn on the service-changed characteristic by default.



Bugfixes

~~~~~~~~



- Raised the maximum number of supported characteristics/descriptors to 24

  (was 10 previously). We're beginning to find services like Device-

  Information with several characteristics populated.
