Official support is current (in development) and the last two releases.  So up
to about a year and a half of support.

After this point, it becomes community support.  This really means, if someone
in the community wants to continue support past the YP's support guidelines they
are welcome to do so -- but there won't be any official releases, only checkins
to the repository.

We have done this on some OpenSSL fixes in the past, but it was based on
specific requests and people submitting the fixes to be included with older
versions.
