Version check for new stable release?

[RBoy]

我正在查看这篇关于使用特定版本的帖子：

How would I install a certain (old) version of Discourse

Checkout the same version of discourse_docker that you use on your other server, maybe copy your app.yml from the old server and make the necessary changes. Also in app.yml, change the version from tests-passed to either a tag (e.g. v2.5.0.beta7) or use a git commit hash.

当我在 GitHub 上查看时，我看到 stable 或 tests-passed 分支（而不是标签）。但是，我确实看到了一个 latest-release 标签。stable（分支）和 latest-release（标签）之间有什么区别？
