LibreSSL 2.2.0 发布，此版本是最新的 OpenBSD-current 版本，最新的 OpenBSD-stable 版本是 2.1.7。
* AIX Support – thanks to Michael Felt
* Cygwin Support – thanks to Corinna Vinschen
* Refactored build macros, support packaging libtls independently.
There are more pieces required to support building and using OpenSSL
with libtls, but this is an initial start at providing an
independent package for people to start hacking on.
* Removal of OPENSSL_issetugid and all library getenv calls.
Applications can and should no longer rely on environment variables
for changing library behavior. OPENSSL_CONF/SSLEAY_CONF is still
supported with the openssl(1) command.
* libtls API and documentation additions
* Various bug fixes and simplifications to libssl and libcrypto
* Fixes for the following issues are integrated into
