**coap-service**
- [v4.0.3](https://github.com/ARMmbed/coap-service/releases/tag/v4.0.3) (15-Sep-2016)
[Full Changelog](ARMmbed/coap-service@mbed-os-5.0-rc1...v4.0.3)
**New features**
- Updated coap-service to use new structure from mbed-client-c

Move the library files used by both nanostack and client into a common
location. This allows both client and nanostack to be built stand-alone.
The patch moves the following libraries into a common location:
-mbed-client-c
-mbed-client-randlib
-mbed-trace
-nanostack-hal-mbed-cmsis-rtos
-nanostack-libservice
-sal-stack-nanostack-eventloop
And moves the library 'coap-service' from client into nanostack.
