    IETF wants to deprecate TLS 1.0 and 1.1

    Hi,

    Don't know whether it's interesting for David and his supporting programmers. I've just read the following article with HEISE.de, a german security news page: IETF will alte TLS-Versionen verbieten (unfortunately in german). But they've linked to following english page: TLS-OldVersions-diediedie.

    Is Mercury using already the newer standards? I remember different discussions where users asked for new SSL standards for Mercury ...
