- Store ACK's also into duplicate info list.
- ROM size optimization. Flash size has gone down ~1100 bytes.
**Closed issues:**
- IOTCLT-3592 - Client does not handle Duplicate ACK messages during blockwise registration correctly
- Remove dependency to yotta tool
- Do not remove stored (GET) blockwise message when EMPTY ACK received. When non piggybacked response mode is used original GET request must not be removed from the stored message list.Message is needed for building the next (GET) blockwise message.
- Move definitions to sn_config.h
Nanostack related files moved under 'feature/nanostack'
Common libraries moved to 'features/frameworks'
Allow FEATURE_COMMON_PAL still to be defined in the build so
that we don't break any builds.
