[Security] TLS 1.n

[Alexander Holler]

Hello,

reading some news items about possible problems with TLS 1.0 (that 
BEAST), is there someone out here who has tested or knows something 
about interoperability of TLS 1.0 with TLS 1.1 or TLS 1.2, especially in 
regard to XMPP?

I'm asking especially because I've read something about possible 
interoperability problems when using 1.1 or 1.2. I don't know if those 
problems only happen with some cruel implementions or whatever and up to 
now I haven't tested it myself.

Because openssl offers the newer versions only since 1.0 or such, I 
never spend any thought on that and before I'm diving myself into that 
topic I thought I might try to ask here before. ;)

Regards,

Alexander
