@ -9,6 +9,9 @@ vNEXT:
no longer required, 'name' field can now contain
'sni' or 'regex', with corresponding options (see
example.org)
Added 'log_level' option to each protocol, which
allows to turn off generation of log at each
connection.
v1.17: 09MAR2015
Support RFC5952-style IPv6 addresses, e.g. [::]:443.
