I see that there are a number of versions of Vault in the GitHub releases page (e.g. 1.5, 1.4, 1.3, 1.2, 1.1, 1.0, etc.). What is the support lifecycle for each minor release? For example, is a minor release supported for N months after a release? Are only the last 1 or 2 minor releases supported?
As of a week ago, I noticed that 1.2 and newer had releases published, so I assume there is some sort of EOL policy, but I did not find it anywhere.
