* How does the versioning scheme work?
After the release of OpenSSL 1.0.0 the versioning scheme changed. Letter
releases (e.g. 1.0.1a) can only contain bug and security fixes and no
new features. Minor releases change the last number (e.g. 1.0.2) and
can contain new features that retain binary compatibility. Changes to
the middle number are considered major releases and neither source nor
binary compatibility is guaranteed.
Therefore the answer to the common question "when will feature X be
backported to OpenSSL 1.0.0/0.9.8?" is "never" but it could appear
in the next minor release.
