haproxy-devel, several improvements / fixes:

-combine certificate acl's with user acl's
-wildcard certificate acl handling
-better handeling of 'transparent' backends when using mixed ipv4 and ipv6, a single defined backend can write 2 backends to the config ipv4 / ipv6
-option to negate a acl
-moved acl definitions above advanced user config in cfg (to allow user config to use already defined acls)
-toggle in frontend overview to easily enable/disable a frontend
