The following new configuration parameters were added: delete_orphans,
spooldir, portm, and plugindir. Some bugfixes and improvements to plugins have
also been added.
This release adds more configurable values, a multilevel and multisystem log, and new write functions for the plugins to better allow plugin debugging. Use of the Operator: header when posting a message now lets the client select the outgoing operator, phone number prefix matching is now regex, the client now features --listop to list the server's supported operators, and the UCP-plugin now supports opcode 51.
