 ## 4.7.2
 
-* **macOS:** fix App Store Connect error `90238` ("does not satisfy its designated Requirement") for bundled native modules after Xcode distribution signing ([#250](https://github.com/flet-dev/serious-python/issues/250)). See `serious_python_darwin` 4.7.2.
-* **iOS/macOS (CocoaPods):** fail `pod install` when a Python runtime preparation script fails, preventing builds from continuing with an incomplete runtime. See `serious_python_darwin` 4.7.2.
+* **Packaging:** report packaging exceptions on stderr and exit with status `1`, so CI and `flet build` stop on failure while temporary files are still cleaned up ([#252](https://github.com/flet-dev/serious-python/pull/252)).

 ## 4.7.2
 
-* **macOS:** fix App Store Connect error `90238` ("does not satisfy its designated Requirement") caused by linker-signed native modules ([#250](https://github.com/flet-dev/serious-python/issues/250)). Staging now replaces linker signatures on `.so` and `.dylib` files in the stdlib, site-packages and app with regular ad-hoc signatures. This preserves their signing identifiers when Xcode re-signs them for distribution, avoiding a mismatch with their designated requirements.
-* **iOS/macOS (CocoaPods):** `pod install` now stops when a Python runtime preparation script exits with an error. Previously, the podspec ignored these failures, allowing builds to continue despite native module signing errors, provider integrity mismatches, or provider signature verification failures in `require` mode.
