4.0 (2018-03-20)
----------------
- Moved code-base to C++11
    - Use C++11 threading instead of Boost.Thread library
    - Use C++11 smart pointers instead of Boost's
- Migrated from Boost.Signals to Boost.Signals2
- Build without warnings on our CI platforms
- General cleanup like remove of superflous files and #include statements. This means header files that previously were included implictly need to be explicitly included now
- Support IPv6 addresses in URLs
- Handle sessions being closed by the server
- Verify certificates when using HTTPS in BOSH connections
- In memory caching of latest entity capabilites lookups
- Changed source code style to use soft tabs (4 spaces wide) instead of hard tabs. Custom patches for Swiften will need to be reformatted accordingly
