Groovy Podcast

The Groovy Podcast returns, live from Community over Code 2026 in Glasgow. Ken Kousen sits down with Paul King to cover what's new in Apache Groovy 6, including the "seven pillars" from Guillaume Laforge's Groovy 6 showcase: language ergonomics, async/await, the GPars-inspired concurrency toolkit, design by contract for AI-generated code, performance and GraalVM native images, the new Markdown and HttpBuilder modules, and compiler improvements like reification and short error messages. Then Søren Berg Glasius from the Grails PMC joins to talk about Grails 8, the plugin ecosystem, and the roadmap to Grails 9 and Groovy 7.
