@@ -20,6 +20,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 - **Graceful error recovery.** If a page crashes, you now see a friendly error screen with a "Try again" button instead of a blank white page. Each section of the app has its own error message so you know exactly what went wrong.
 - **Security headers.** All pages now include clickjacking protection, MIME-sniffing prevention, a strict referrer policy, and HSTS. Browser APIs like camera and microphone are explicitly disabled.
 - **Better form experience.** Forms now auto-focus the first field when they open, text inputs enforce character limits with a visible counter when you're close, and the settings page warns you before navigating away with unsaved changes.
+- **Tighter name limits.** Site, funnel, and monitor names are now capped at 100 characters instead of 255 — long enough for any real name, short enough to not break the UI.
