- httpolyglot is removed, we no longer automatically redirect from http to https
- server.ssl.redirectHttpFromPort option added to allow for http -> https redirect from one port to another
- We no longer start the dev server with tls by default, it can be turned on with the --ssl flag, npm start -- --ssl, or ./bin/kibana --dev --ssl
- There will currently be error log messages if you connect over the wrong protocol, we have #11209 for downgrading these
