@ -46,6 +46,8 @@ Broker:
- When "require_certificate" was false, the broker was incorrectly asking for
a certificate (but not checking it). This caused problems with some clients
and has been fixed so the broker no longer asks.
- When using syslog logging on non-Windows OSs, it is now possible to specify
the logging facility to one of local0-7 instead of the default "daemon".
Clients:
- Both clients can now load default configuration options from a file.
