What is the best way to find the latest stable build that can be run in a Production Environment?
There doesn’t seem to be a release in https://github.com/ory/hydra/releases that isn’t marked as pre-release.
Hydra has no stable version yet (indicated by the 0.x prefix). It’s ok to run it in production, but you need to be aware that there isn’t a thing such as an LTS, meaning that the newest changes and patches will always be on the latest version, never on a previous one. Let’s say there’s an issue introduced in 0.7.0. It might not be discovered until 0.8.0. The fix will not be released for 0.7.0, only for 0.8.0 as that is the current “stable” release.
A general rule is that there are breaking changes in each minor version until we hit major version 1. So 0.8.0 has breaking changes to 0.7.0. Typically, any releases that aren’t prepended by something like beta or alpha or rc (e.g. 0.10.0-alpha.1) are considered stable for production, with the risks cited above.
