v2.1.0

Observer 2.1.0

Changes

• Removed apex_observer class from the public API and moved it to detail namespace of the observer library.
• Fixed compilation with C++17 or newer.
• Build tests, examples and benchmark with C++17.

v2.0.2

Observer 2.0.2

Changes

• Revisited noexcept specifiers.
• Fixed a universal reference for the pg::connection_owner::connect overload that connects function objects.
• Fixed connecting const member functions for instances that are const.

v2.0.1

Observer 2.0.1

Changes

• pg::connection_owner now uses a std::vector instead of a std::set to store connections.
• Added pg::connect functions which return a pg::scoped_connection.
• Renamed pg::observer_owner to pg::connection_owner and provided an alias for the old name to ensure backwards compatibility.
• pg::connection_owner supports static polymorphism for subjects.
• Added pg::blockable_subject.

Breaking changes

• The overload pg::connection_owner::connect which connected one subject to another is removed. Use the connect overload for member functions instead. See tests or chain_subjects example.
• pg::subject is no longer blockable, use pg::blockable_subject instead for cases that needs to block a subject.
• pg::subject_blocker now requires subjects to provide a block and a unblock function, for example like pg::blockable_subject.
• A connection is no longer automaticly invalidated. The usability of this feature didn't justify the extra complexity.
