The LibreSSL version scheme corresponds to OpenBSD version numbers:<p>2.0.x -> OpenBSD 5.6,
2.1.x -> OpenBSD 5.7,
2.2.x -> OpenBSD 5.8,<p>Development slowed approaching the end of 2.1.x as the OpenBSD tree went in release mode lockdown. It is interesting to see the development coordination that stops and restarts the tree activity.<p>Things in the pipeline for 2.2.x include AIX, Cygwin, Visual Studio support, and wider support for optimizations (currently only ELF/OS X x64 is supported). In general, expect libtls to expand in features and improve usability, more code to be pruned and simplified.<p>There were not many SSL patches for OpenBSD 5.6, and there were not any LibreSSL 2.0.x releases after 2.1.x began. However, we are looking at possibly releasing further 2.1.x updates if there is interest. They would correspond to OpenBSD 5.7 errata.
From the release announcement :<p>This or earlier LibreSSL releases may also address issues that are to be revealed by The OpenSSL Project Team on the 19th of March, 2015.
