* (bug 32951) Do not register internal externals with absolute protocol,
when server has relative protocol.
+* (bug 39005) When purging proxies listed in $wgSquidServers using HTTP PURGE
+ method requests, we now send a Host header by default, for Varnish
+ compatibility. This also works with Squid in reverse-proxy mode. If you wish
+ to support Squid configured in forward-proxy mode, set
+ $wgSquidPurgeUseHostHeader to false.
