FWIW, The next release of OpenSSL is an LTS release and will be supported for five years.  It disables SSLv3 by default, but does enable TLS1.0 and TLS1.1 by default.  (It also includes TLS1.3, nudge nudge RFC editor queue.)

    Hello,
    
    Stephen and I posted the draft below to see if the TLS working group
    is ready to take steps to deprecate TLSv1.0 and TLSv1.1.  There has
    been a recent drop off in usage for web applications due to the PCI
    Council recommendation to move off TLSv1.0, with a recommendation to
    go to TLSv1.2 by June 30th.  NIST has also been recommending TLSv1.2
    as a baseline.  Applications other than those using HTTP may not have
    had the same reduction in usage.  If you are responsible for services
    where you have a reasonable vantage point to gather and share
    statistics to assess usage further, that could be helpful for the
    discussion.  We've received some feedback that has been incorporated
    into the working draft and feelers in general have been positive.  It
    would be good to know if there are any show stoppers that have not
    been considered.

    Abstract:
       This document [if approved] formally deprecates Transport Layer
       Security (TLS) versions 1.0 [RFC2246] and 1.1 [RFC4346] and moves
       these documents to the historic state.  These versions lack support
       for current and recommended cipher suites, and various government and
       industry profiiles of applications using TLS now mandate avoiding
       these old TLS versions.  TLSv1.2 has been the recommended version for
       IETF protocols since 2008, providing sufficient time to transition
       away from older versions.  Products having to support older versions
       increase the attack surface unnecessarily and increase opportunities
       for misconfigurations.  Supporting these older versions also requires
       additional effort for library and product maintenance.
    
       This document updates the backward compatibility sections of TLS RFCs
       [[list TBD]] to prohibit fallback to TLSv1.0 and TLSv1.1.  This
       document also updates RFC 7525.
    
    
    
    
    Please note that it may take a couple of minutes from the time of submission
    until the htmlized version and diff are available at tools.ietf.org.
    
    The IETF Secretariat
