ExCrap: CRAP metrics for change risk

The final episode of Thinking Elixir after six incredible years of weekly episodes! We send things off in style with a packed news segment covering Phoenix LiveView 1.2's new colocated CSS powered by the @scope at-rule, the retirement of the long-standing Earmark Markdown library and why you should migrate to MDEx, a major Sagents v0.8.0 release bringing durable interrupts, and structured extraction, PostgreSQL 19's exciting new features including graph queries, SpaceX's jaw-dropping $60 billion acquisition of Cursor, and more! Finally, David shares his new role on the Erlang Ecosystem Foundation board, and Mark talks about what's next for Sagents and his exciting new AI-native startup. Thank you for six wonderful years. We're so glad you were here along the way and now for the final episode!
