For the record, TLS is effectively the standardization of SSL by the 
IETF for inclusion into protocol stacks - SSL was originally provided as 
an application shim library layered over TCP, and had to be linked into 
every application that used it.

TLS can, I believe, also be referred to as SSL version 3.1, and I 
understand that the only significant change was the addition of a 
broader and more recent set of cipher specifications.
