What's new in Kubernetes 1.19?

Kubernetes 1.19 introduces several significant updates aimed at enhancing usability, security, and feature stability, along with extending the support window from nine to 12 months, which eases the upgrade process for users. This release includes 34 enhancements, with 10 new features, eight graduating to stable, two management changes, and 14 existing features receiving updates. Notable improvements include the introduction of generic ephemeral inline volumes, a structured logging system, and a new protocol for steady feature development.
