With Loki, like with Freya, I was pleasingly surprised to find the beta better in some respects than the previous version, so I want to use it.
But are questions on the beta release off-topic? And if so, are they all off-topic, or only those related to what normally is expected to be a problem in a beta?
(For example, just asking if in a beta some feature is absent by design or by a possible bug should not be off-topic, in my opinion.)
