+This release adds an environment check in `@sentry/nextjs` for Vercel deployments (using the `VERCEL_ENV` env variable), and only enables `SentryWebpackPlugin` if the environment is `production`. To override this, setting `disableClientWebpackPlugin` or `disableServerWebpackPlugin` to `false` now takes precedence over other checks, rather than being a no-op. Note: Overriding this is not recommended! It can increase build time and clog Release Health data in Sentry with inaccurate noise.
