SLF4J 1.7.26 was released on 16 March, Openfire should be updated to this version.
Is it really for 4.2.4?
I reckon so. It's a trivial change, and may remove a red-flag for those that care about such things. However, it's not that important to me, happy to leave it for 4.4 if others think it's not relevant.
I mean, 4.3.2 is the latest version, not 4.2.3 😉
Ah, yes. A very good point. Clearly more coffee required!
