Prior to the existance of LTS releases (versions older that 5.0) where supported for 2.5 years.
So I’m wondering if versions 4.2, 4.4 and 4.6 are still supported as they are older than one year but they where supported by the previous release process.

For me, the contract changed after the release so we should stick with what was announced at the release time.
