ISSUE #212

23rd of August 2020

Hi folks! This week Kotlin 1.4.0 was finally released, and we have been checking it out - maybe it has not been as commented as others, but we are particularly happy with the Explicit API mode for library authors - maybe too much work on SDKs from this author. We hope that this gives you good learning material for this week - enjoy this Sunday.
