Manage Vercel Flags Segments Directly with Vercel CLI
Vercel has introduced command-line interface capabilities to manage feature flags segments, streamlining configuration workflows for Next.js and SvelteKit applications.

The latest Vercel update enables software engineers to manage Vercel Flags segments directly using the Vercel CLI. This change allows operations that previously required the Vercel dashboard to be scripted and automated through the terminal, enhancing developers' operational efficiency and lowering the risk of manual configuration errors.
