Common

• Client Core - Reduce shared pointer usage, figure out ways to use fewer copy operations
• MQTT - if subcriptions are disallowed by the policy, enabling auto resubcribe can lead to a connect-disconnect loop, issue #94
• Network Read - Add recovery options for out of sync buffers
• Network Layer, Common - Currently, vector resize is called before the vector is passed for reading in data. Determine if a more flexible solution is possible with fewer allocations
• Network Layer, OpenSSL - error handling for library API call
• Network Layer, OpenSSL - setting for disconnect timeouts
• Network Layer, WebSocket - Refactor WSLay and merge it with the WebSocket wrapper, improve testing
• Network Layer, WebSocket - TLS Read and Write are highly inefficient in current implementation, improvements required
• Network Layer, Common - Add support for IPv6, remove deprecated system API calls
• Shadow - Refactor delta requests into separate function
• Shadow - Add action for automatically performing Shadow updates
• Samples, Shadow - Add Console Echo Sample
• Threading - lock-order-inversion (potential deadlock), issue #14
• CLI, Configuration - Add support for command line cert paths
• CMake, path warnings - Cleaner way to download repositories from github and build them
• CMake, build settings - Provide options for setting up certain values that are hardcoded using macros at the moment
• Testing - More edge case testing required for Reconnect logic
• Testing - Improvements needed on Integration testing for network reference layers specifically for different compilers and platforms
• UTF-8 string - improve validation checks

Windows

• Build issues with VS 2013
• Project structure in Solution Explorer needs to be updated
• CMake warnings on solution generation
• Working directory needs to be updated every time CMake solution is rebuilt to ${OutDir} for configuration to be picked up as expected
