[stunnel-users] Life cycle information

[Ben Harper]

Greetings,

I am trying to confirm some life cycle information, mainly supported 
version(s) and what versions do not insure backwards compatibility.

It would appear that only the latest version is supported, per the first 
item under 'Before you send your question to stunnel-users' on the 
Mailing Lists page[0].

Does this project use semantic versioning?  Will incompatibilities only 
come when a 6.x.x version is released?  It seems at one point this was 
the case per the 'Upgrading to stunnel 4' link on the Documentation page[1].

Are my assumptions correct?

Thanks,
Ben
