Hi,

According to http://www.openssl.org/news/changelog.html, Initial TLSv1.1 support was introduced in the first release of openssl v1.0.1, Initial v1.2 support was added at the same time.

I'm using CentOS 6.4 with openssl-devel 1.0.0-27 (which has version 0x10000003L) and the tls module does not compile (without warnings) and fails to run due to undefined v1.1 methods.

Was there a reason for selecting the 05 release of v1.0.1 (i.e. v1.0.1e) for TLSv1.2 support? As far as I can see the TLSv1_2_method() is available from the first release? Maybe a required bugfix?

Hugh
