3.8.3 - 2012-10-04

• Fixed setting "size" bigger than 4GB on 32bit architectures
• Do not overwrite mode set by "create" option when using ACL. "create" directive is now not mixed up with ACLs. If you use "create" in config file and log file has some ACLs set, ACLs are not kept and are overwritten by the mode set in "create" directive.
• Mode argument in "create" directive can be omitted. Only owner and group is set in this case. Check man page for more info.
