ZIO News - Issue #20

Welcome to ZIO News, your monthly newsletter dedicated to ZIO and its ecosystem!

Since the big 1.0 release, there was a minor 1.0.1 release that mostly fixes bugs. It is recommended to upgrade especially if you use zio Schedule (or a library that relies on it like zio-kafka) as it fixes a few important bugs. This release is entirely binary compatible with 1.0.0 so you can upgrade directly without worrying about other dependencies. Here are the full release notes.

A quick note to mention that ZIO added an “Adopters” section on its README, where you can see a few companies using ZIO (22 already). Add your own by opening a simple PR!
