我怎么判断特定的Discourse客户端发行版是否是自由软件？

[Jagster (Jakke Lehtonen)]

人们称这个团队或公司为 CDCK。当然，他们每天都在这样做。它处于持续开发中。然而，这正是我们正在使用的。

这可能会引出这个问题：

Is Discourse always in "beta"?

I noticed that every now and then my Discourse site send me an email telling that a new version is available to install, but every time the version is “x.y.z.beta something”, so I’d like to know: is Discourse always some “beta” version? Is it good to install in a production environment (i.e. to serve hundreds, maybe thowsands people)? Or does this concerns only free and not “cloud” versions?
