The legacy init packet (pre v25) sends information about the client's password that a server could use to log in to other servers if the username and password are the same. All the other benefits of SRP of protocol v25 are missed if the legacy init packet is still sent during connection creation. This patch adds an option to not send the v25 init packet. Not sending the v25 packet means breaking compat with pre v25 servers, but as the option is not enabled by default, no servers are affected unless the user explicitly flips the switch. More than 90% of the servers on the serverlist support post v25 protocols. The patch also fixes a bug with greying out of non compliant servers being done wrongly, the min and max params were mixed.
