Added

• namedpoint functions in the C++ for publications and subscriptions, and corresponding functions in the C interface and language API's
• boolean publication and subscription for C++ interface, and corresponding functions in the C interface and language API's
• new options for brokers, --local, --ipv4, --ipv6, --all, are shortcuts for specifying external network interfaces
• additional documentation, CONTRIBUTORS, ROADMAP, CONTRIBUTIONS, and some other other documentation improvements

Changed

• the default interface configuration for federates and brokers. The --interface option is less important as interfaces should mostly get automatically determined by the broker address
• minor configuration changes to cmake to be more conforming with modern cmake best practices
• cleaned up header installation for app directory
• shared libary construction now uses some headers generated by cmake

Fixed

• better error checking in the C interface
• fixes for occasionally failing tests
