✨ New blog post: "STF Milestone 3: Release verification and automation"

A major goal of the @sovtechfund is to help projects become more sustainable and decrease their truck factor. For #JUnit, one activity in desperate need of improvement in this area was performing a release. Prior to this milestone, all JUnit releases of the past years had been performed from my local computer. It was high time to change that!
