Plugin version constraints
RabbitMQ now has a mechanism for plugin authors to indicate what versions a plugin is compatible with. Incompatible plugins are logged and ignored.
Lager-based logging: pluggable backends, debug log level, more flexibility in

This brings a group of benefits: (quite verbose) debug log level, pluggable logging
backends (e.g. logging to Syslog no longer requires external tools), and much
more flexibility in logging configuration.
