Hey, thanks for opening this PR! This makes sense to me on first glance but I'll let @JPeer264 and @AbhiPrasad have the final say.

This PR contains the following updates: | Package | Change | [Age](https://docs.renovatebot.com/merge-confidence/) | [Confidence](https://docs.renovatebot.com/merge-confidence/) | |---|---|---|---| | [@sentry/react](https://github.com/getsentry/sentry-javascript/tree/master/packages/react) ([source](https://github.com/getsentry/sentry-javascript)) | [`10.27.0` -> `10.28.0`](https://renovatebot.com/diffs/npm/@sentry%2freact/10.27.0/10.28.0) |  |  | --- ### Release Notes <details> <summary>getsentry/sentry-javascript (@​sentry/react)</summary> ### [`v10.28.0`](https://github.com/getsentry/sentry-javascript/releases/tag/10.28.0) [Compare Source](getsentry/sentry-javascript@10.27.0...10.28.0) ##### Important Changes - **feat(core): Make `matcher` parameter optional in `makeMultiplexedTransport` ([#​10798](getsentry/sentry-javascript#10798 The `matcher` parameter in `makeMultiplexedTransport` is now optional with a sensible default. This makes it much easier to use the multiplexed transport for sending events to multiple DSNs based on runtime configuration. **Before:** ```javascript import { makeFetchTransport, makeMultiplexedTransport } from '@​sentry/browser'; const EXTRA_KEY = 'ROUTE_TO'; const transport = makeMultiplexedTransport(makeFetchTransport, args => { const event = args.getEvent(); if (event?.extra?.[EXTRA_KEY] && Array.isArray(event.extra[EXTRA_KEY])) { return event.extra[EXTRA_KEY]; } return []; }); Sentry.init({ transport, // ... other options }); // Capture events with routing info Sentry.captureException(error, { extra: { [EXTRA_KEY]: [ { dsn: 'https://key1@​sentry.io/project1', release: 'v1.0.0' }, { dsn: 'https://key2@​sentry.io/project2' }, ], }, }); ``` **After:** ```javascript import { makeFetchTransport, makeMultiplexedTransport, MULTIPLEXED_TRANSPORT_EXTRA_KEY } from '@​sentry/browser'; // Just pass the transport generator - the default matcher handles the rest! Sentry.init({ transport: makeMultiplexedTransport(makeFetchTransport), // ... other options }); // Capture events with routing info using the exported constant Sentry.captureException(error, { extra: { [MULTIPLEXED_TRANSPORT_EXTRA_KEY]: [ { dsn: 'https://key1@​sentry.io/project1', release: 'v1.0.0' }, { dsn: 'https://key2@​sentry.io/project2' }, ], }, }); ``` The default matcher looks for routing information in `event.extra[MULTIPLEXED_TRANSPORT_EXTRA_KEY]`. You can still provide a custom matcher function for advanced use cases. - **feat(nextjs): Support cacheComponents on turbopack ([#​18304](getsentry/sentry-javascript#18304 This release adds support for `cacheComponents` on turbopack builds.
