Scala 2.12 artifact missing

[steinybot]

The release notes say:

Version 0.6.2 (17.09.20)
Published for Scala 2.12.x/2.13.x, Scala.js 1.0, and Scala Native 0.3.9/0.4.0-M2.

but I can't find the 2.12 version: https://mvnrepository.com/artifact/biz.enef/slogging-slf4j

Ahh I can't use 0.6.1 either as I am using Scala.js 1.0 but Scala 2.12. Is it safe to use a 0.6.1 backend with 0.6.2?
