What is the OPNsense release strategy?

The OPNsense Roadmap version naming system consists of year.month, so the first release took place in January 2015 -> release 15.1 In the event of minor releases within the same month an extra number will be added, like 24.1.2 We plan to use a 6 months major release cycle with firm release dates. Major release versions will have code names of animals, mountains or whatever we can think of that sounds good. Each release has a number, a code name and a release date.
