DESCRIBE YOUR PR

Updates three feature descriptions in the shared FeatureInfo component (src/components/featureInfo.tsx) so they're accurate on every platform that uses them. The component renders the "Want to learn more about these features?" and "Need help locating captured data in your Sentry project?" expandables on the JavaScript, Python, Dart/Flutter, and Ruby quick starts, plus React Native on its quick start template branch.

Issues description

• Before: "...automatically reports errors, uncaught exceptions, and unhandled rejections."
• After: "...automatically reports errors, uncaught exceptions, and crashes."
• "Unhandled rejections" is JavaScript-specific (promise rejections). It shows on every page that lists Issues, including Python, Ruby, and Dart, where it doesn't apply.
• The old text didn't mention crashes. Native crashes are a core part of error monitoring on React Native, Flutter, Electron, and Capacitor.

Session Replay description

• Before: "...a video-like reproduction of what was happening in the user's browser..." linking to /product/session-replay/web
• After: "...a video-like reproduction of what users saw in your app..." linking to /product/session-replay/
• Session Replay also records mobile app screens (Flutter on master, React Native on its template branch), so "browser" and the web-only link were inaccurate there. The overview page covers both web and mobile replay.

Profiles navigation

• Before: "Open the Profiles page, select a transaction, and then a profile ID to view its flame graph."
• After: "Open the Profiles page to see your slowest functions and an aggregate flame graph of your most frequent code paths. If tracing is enabled, select a transaction to see the flame graph for that part of your app."
• The old steps describe transaction-based profiling. Python and the JavaScript server SDKs now use continuous profiling, and the browser-based guides (Astro, React Router, Remix) use profileSessionSampleRate. Selecting a transaction opens an aggregate flame graph rather than a list of profile IDs, as described in Profiling Page.
• The new wording works for both profiling types. Ruby still uses transaction-based profiling. Platform-specific details stay on each platform's profiling pages, and the existing Profile Details link is unchanged.

Where to see it (all are in collapsed expandables):

• Issues and Session Replay: https://docs.sentry.io/platforms/javascript/guides/react/ under Configure → "Want to learn more about these features?" (Python's page doesn't list Session Replay)
• Profiles: https://docs.sentry.io/platforms/python/#view-captured-data-in-sentry → "Need help locating captured data in your Sentry project?"

[cursor]

The plan checks the new Issues, Session Replay, and Profiles copy on platform quick starts. It also watches render errors, page loads, and HTTP 5xx on those pages. An issue escalates when the old copy remains, render errors appear, those page loads drop, or the new Session Replay link 404s.

Rollout complete

Services: sentry-docs, develop-docs.

Plan

What changed

Platform quick start expandables now describe Issues as errors, uncaught exceptions, and crashes. Session Replay copy now says app instead of browser, and its title link now points to the Session Replay overview. Profiles help now describes aggregate flame graphs for both profiling types.

sentry-docs must deploy before this copy is live. develop-docs also builds this shared source file. FeatureInfo only renders on user documentation quick starts. React Native is not on that render path in this merge. The runtime Sentry project tag is docs.

Risk

A FeatureInfo render failure hides every feature blurb in those expandables. That includes Tracing, Logs, Replay, Metrics, and User Feedback. Those expandables sit on JavaScript, Python, Dart, Flutter, and Ruby quick starts. The Session Replay title link now targets the overview page. A broken overview path would send readers to a 404. A compile error in this file can fail both production deploys.

Intended effect

The new copy and the new Session Replay link must appear in the HTML of the platform quick starts. Absence is the old Issues, Session Replay, or Profiles wording still on the page.

Signal	Baseline	Window	Rule	Source
Issues learn-more text	Old phrase unhandled rejections is still present	Fetch at 2026-10-27T19:57:00Z	Must show automatically reports errors, uncaught exceptions, and crashes. The old phrase must be gone	GET https://docs.sentry.io/platforms/python/ and https://docs.sentry.io/platforms/javascript/guides/react/
Session Replay learn-more text and title link	Old phrase user's browser is still present on the React quick start	Fetch at 2026-10-27T19:57:00Z	Must show what users saw in your app. The title link must target /product/session-replay/ not /product/session-replay/web	GET https://docs.sentry.io/platforms/javascript/guides/react/
Profiles find-in-Sentry text	Old steps select a transaction, and then a profile ID are still present	Fetch at 2026-10-27T19:57:00Z	Must show aggregate flame graph of your most frequent code paths. The old profile ID steps must be gone	GET https://docs.sentry.io/platforms/python/

Repeat the Issues string test on https://docs.sentry.io/platforms/javascript/ and https://docs.sentry.io/platforms/ruby/. Repeat the Session Replay string test on https://docs.sentry.io/platforms/dart/guides/flutter/. Python does not list Session Replay.

Regression watch

A throw in FeatureInfo would blank every feature blurb in the same expandable. Watch render errors and that the quick start pages still load. Watch that the new Session Replay overview link does not 404.

Do not treat Event: Event Event captured as promise rejection as this change. Production had 795 error events in the window. Most of that volume is unrelated client noise.

Changed-path slice in the same 24h window: /platforms/javascript/ 92 loads, /platforms/python/ 76 loads, /platforms/javascript/guides/react/ 67 loads, /platforms/dart/guides/flutter/ 44 loads. Escalate if Python, JavaScript, React, or Flutter landing loads fall to zero. The Session Replay overview already has 84 loads at /product/session-replay/. The old web page still has 25 loads at /product/session-replay/web/.

Not observable

LCP for /platforms/ pageloads returned no rows in the first plan, so web vitals stay unknown. Prior-day docs.page.load for the landing paths was not measured as its own window, so a modest drop on those paths cannot be judged. Plausible Open Expandable events are not connected. Pageload spans are sampled at 0.3. develop.sentry.dev does not render FeatureInfo. React Native quick starts do not use FeatureInfo in this merge.

Verified in production

• The new Issues, Session Replay, and Profiles copy is live on the platform quick starts.
• Live platform quick starts still show the new copy, and render errors and 5xx stayed at zero.
