September 2025; Prismicio/slice-machine: two key features delivered, a documentation bug fix, and enhanced telemetry. Slice Concept Clarification improves onboarding by explaining slices as reusable page sections that map to code components; updated a blank slate message to explicitly define what a slice is. Introduced a feature-flag-controlled information banner in the Slice Machine UI with customizable title, description, and optional CTA, including telemetry events for dismissal and CTA clicks to improve engagement measurement. These changes reduce onboarding time and enable safer UX experimentation. Technologies demonstrated include React/TypeScript frontend work, feature flags, telemetry instrumentation, and documentation craftsmanship.
