[erlang-questions] Re: ssl and {active, once} - bug?

[Ingela Andin]

Hi!

Tonys code will accomplish that you run the new ssl-implementation
instead of the old one. I would not run the new ssl in older
versions than R13 even though there is a primitive version in R12.
The main reason for not making the new one default yet is that we
want it to be as complete as possible before that, but that does not
necessarily mean it is not complete enough for your need.
