 ## [Unreleased]
 
+## [1.10.2] - 2026-08-28
+
+### Fixed
+
+- Sentry wasn't instrumenting Express (`[Sentry] express is not instrumented` at startup): `express`, `cors`, and `@prisma/client` were required at the top of `backend/src/index.js` before `Sentry.init()` ran, but Sentry's auto-instrumentation patches those modules via a require hook that only works if `Sentry.init()` runs first. `Sentry.init()` now runs immediately after `dotenv.config()`, before any of the libraries it instruments are required.
+
 ## [1.10.1] - 2026-08-28
 
 ### Security
