Release 0.1.0

=============



Mostly API changes.



Features

~~~~~~~~



- onConnection() callback now receives connection-parameters applicable to the

  new connection.



- onDataSent() callback now receives a count parameter containing the number of

  times notifications were sent out since the last callback.



- A 'reason' parameter has been added to Gap::disconnect() to indicate the

  reason for disconnection; and also to the onDisconnection callback to

  receive a reason from the remote host.



Bugfixes

~~~~~~~~



- onDataWritten() callback now receives an additional parameter

  (GattServer::WriteEventCallback_t) encapsulating the update. This avoids

  having to re-fetch the updated characteristic's value attribute. It also

  fixes a bug where multiple updates to the characteristic's value-attribute

  could get clobbered if they occurred in quick succession before the

  callbacks could be processed.
