Author: Rohit Grover

Release 2.1.3

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



* Improvements to CallChainOfFunctionPointerswithContext:

  - add a `detach` function to be able to remove callbacks.

  - detach function now return true if a function has been detached and

    false otherwise.

  - add a function call operator.

  - use safe-bool idiom. see : http://www.artima.com/cppsource/safebool.html



* Add SafeBool class which allow to easily declare a safe bool operator in

  c++03.



* Improvements to FunctionPointerWithContext:

  - fix call propagation

  - use safe bool idiom



* Add config file for generating Doxygen.



* Setup for onRadioNotification callback does not call initRadioNotification

  anymore.



* GapAdvertisementData now handles replacement and appending of data fields

  based on type. Some fields can be replaced with new values, and others

  require the payload to be appended.
