The new scheme is made of monotonically increasing numbers:
- major, incremented for backward compatibility breaking changes
- minor, incremented for changes in dependencies and exposed interfaces
- micro, incremented for bug fixes
This impacts the current security policy as well:
- the current stable series is 1.15.x
- the old stable series is 1.14.x
Only these two series will see security fixes. We recommend downstream distributions to use versions from the 1.15.x series.
