Minor Changes

  • 39850ef: Add vercel connect update <id> subcommand to change connector branding. Accepts --icon (PNG or JPEG path, uploaded to Vercel and sent as SHA-1), --background-color, and --accent-color (both #RRGGBB). Gated behind the existing FF_CONNEX_ENABLED flag.
  • 63a66d4: Add --icon, --background-color, and --accent-color flags to vercel connect create. The icon is uploaded to Vercel before the connector is created. When the API requires a browser registration step, branding is appended to the dashboard URL so the create form can prefill itself; the CLI also applies a follow-up PATCH after the browser flow as a safety net for the dashboard rollout. Gated behind the existing FF_CONNEX_ENABLED flag.
  • 137e5d1: Allow builder V2 to expose startDevServer.
  • b1aa926: [vc dev] handle process errors in dev server

Patch Changes

  • a3a1a5a: Added CLI eval support for comparable agent/model experiment runs and restored transcript artifact uploads via chunked result ingestion.

  • 18e9fd6: fix(cli): point vc connect open and registration error URLs at the renamed /connect dashboard route

  • 4118600: Fix standalone CLI binary latest-version worker startup.

  • 80e8e06: Track Vercel plugin active-session markers in CLI telemetry.

  • bb61428: Include framework slug in output/config.json

  • f45e466: Add opt-in automatic CLI updates via vercel upgrade --enable-auto and prompt users to enable them after a successful manual upgrade.

  • a3a1a5a: Add offline-friendly local modes for CLI eval discovery and dashboard fixture generation, and expand Vercel CLI eval coverage for project, list, inspect, logs, and pull commands.

  • a3a1a5a: Relaxed the CLI env/add eval grader to accept equivalent JSON format syntax and shell-variable env names when outputs prove the variable was added.

  • a3a1a5a: Simplified the implicit curl eval grader to only require that the agent ran vercel curl or vc curl.

  • 8fb4dc8: Add vercel flags split to configure weighted Vercel Flags splits from the CLI.

    Configure a split interactively by letting the CLI prompt for the environment, bucketing attribute, weights, fallback variant, and revision message. vercel flags split welcome-message

    Configure a boolean flag split in production with 95/5 traffic. vercel flags split redesigned-checkout --environment production --by user.userId --weight off=95 --weight on=5

    Configure a string flag split with an explicit fallback variant. vercel flags split welcome-message -e production --by user.userId --default-variant control --weight control=90 --weight treatment=10

    Exclude a variant from receiving traffic by setting its weight to 0. vercel flags split checkout-copy -e preview --by user.userId --default-variant control --weight control=50 --weight treatment=50 --weight legacy=0
