Hey Małgorzata,

Thanks for the reply.  Let me clarify my questions.

Some applications will offer bug fixes and security updates for multiple 
versions, like Python (2.7, 3.4, 3.5 and 3.6) or MariaDB (5.5, 10.0 and 
10.1).  While others will only do this for the a single release, like 
git or vim.  Should I except that stunnel will only provide bug fixes 
and security updates for the latest publicly available tarball?

Along those lines, software versioning varies greatly and different 
projects introduce incompatibilities differently.  Would it be safe to 
say that all versions within the 5.x series would not have intention 

Having life cycle information to guide myself and other users on when 
and how to patch is important, especially for security software.
