Author: Rohit Grover

Release 0.3.7

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



This is a minor set of enhancements mostly around reduce our global static

memory footprint.



Enhancements

~~~~~~~~~~~~



* Reduce the maximum number of CHARACTERISTICS and DESCRIPTORS that can be

  handled. This has memory implications for static global memory. It should

  be possible to re-architect our solution for add_characteristic() to not

  require these limits; hopefully we'll get there soon.



* Move nRF51GattServer::getInstance() into a .cpp file; same for nRF51Gap::getInstance().



* Reduce max bonds to managed by device-manager to 4; this has memory implications for static global memory.



* Reduce pStorage command queue size to 2; this has memory implications for static global memory.



* Replace uses of deprecated Gap::addr_type_t with Gap::AddressType_t.



* Some UUID-related types have moved into UUID class. Minor changes were needed to work around build errors.



Bugfixes

~~~~~~~~



* None.
