+## 4.4.1
+
+* **iOS:** the bundled `_ssl` and `_hashlib` frameworks now ship OpenSSL's official privacy manifest instead of an incomplete stub, correcting what they declare under Apple's third-party SDK requirements. This is a correctness fix and is *not* expected to resolve the `ITMS-91065: Missing signature` App Store rejection reported in flet-dev/flet#6724, which remains under investigation. See `serious_python_darwin` 4.4.1.
+* Bundled python-build snapshot re-pinned to **20260726**. No versions moved — Python (**3.12.13 / 3.13.14 / 3.14.6**), Pyodide, and `dart_bridge` **1.6.1** are unchanged from 20260725.
+
 ## 4.4.0
 
 * **iOS/macOS:** fix built iOS apps crashing at startup with `Failed to lookup symbol 'serious_python_run'`. `dart_bridge` now ships as a dynamic framework, so the FFI entry points Dart and Python resolve via `dlsym` stay exported; previously it was static-linked into the app executable, which exports nothing. Release/device builds only. See `serious_python_darwin` 4.4.0.

+## 4.4.1
+
+* Re-pins the bundled python-build snapshot to **20260726**. Its only functional change is an iOS privacy-manifest fix (see `serious_python_darwin` 4.4.1); no versions moved and the Android runtime is unchanged from 20260725.

 ## 4.4.0
 
 * Re-pins the bundled python-build snapshot to **20260725** (`dart_bridge` **1.5.1 → 1.6.1**). 1.6.1 changes only how `dart_bridge` is packaged for Apple platforms (static library → dynamic framework, see `serious_python_darwin` 4.4.0); the Android runtime is byte-identical to 20260720.

+## 4.4.1
+
+* **iOS: `_ssl.framework` and `_hashlib.framework` now carry OpenSSL's official privacy manifest.** Both extensions statically link OpenSSL, so Apple's App Store scan identifies them as containing BoringSSL / openssl_grpc — a listed third-party SDK that must declare a privacy manifest. The bundled `PrivacyInfo.xcprivacy` was a stub: `NSPrivacyAccessedAPITypes` was an empty array, and it carried an `NSPrivacyUsesNonStandardAPIs` key that isn't part of Apple's schema. It is now byte-identical to the manifest OpenSSL publishes for its Apple builds, declaring the file-timestamp API access the library actually performs (`NSPrivacyAccessedAPICategoryFileTimestamp`, reason `C617.1`). See flet-dev/python-build#35.
+* This does **not** resolve the `ITMS-91065: Missing signature` App Store rejection reported in flet-dev/flet#6724, and shouldn't be read as a fix for it. That rejection cites the same two frameworks but arrives with no accompanying `ITMS-91061`, so Apple does find the manifest. Inspecting a built `.ipa` confirms the frameworks reach Apple signed — valid Apple Distribution authority and team ID, with the manifest sealed into `_CodeSignature/CodeResources` — and that Xcode re-signs every embedded framework with the submitting team's identity at both the embed and `exportArchive` steps, overwriting whatever signature the vendor applied. Root cause is still open; this change removes the one verifiable defect so it isn't a confound.
+* Re-pins the bundled python-build snapshot to **20260726**. No versions moved: Python (**3.12.13 / 3.13.14 / 3.14.6**), Pyodide, and `dart_bridge` **1.6.1** are all unchanged from 20260725, and the privacy manifest above is the only functional difference on any platform.
+
 ## 4.4.0
 
 * **iOS/macOS: `dart_bridge` now ships as a dynamic framework**, fixing built iOS apps crashing at startup with `Failed to lookup symbol 'serious_python_run': dlsym(RTLD_DEFAULT, serious_python_run): symbol not found`. `dart_bridge`'s FFI entry points (`serious_python_run`, `DartBridge_InitDartApiDL`, `DartBridge_EnqueueMessage`, `PyInit_dart_bridge`) are resolved at runtime via `dlsym` — from Dart through `DynamicLibrary.process()` and from Python through `import dart_bridge`. It previously shipped as a **static** archive linked into the host app *executable*, and an iOS executable exports nothing to the dynamic symbol table by default (the release build also strips local symbols), so those lookups failed. Only release/archive (device) builds were affected — debug/simulator builds don't dead-strip, so the failure did not reproduce there. Android was never affected: its `dart_bridge` is a dynamic `.so`, which exports its symbols. `dart_bridge` **1.6.1** now builds `dart_bridge.xcframework` as a dynamic framework (see flet-dev/dart-bridge#11 and #12), so it is embedded + signed into the app like `Python.xcframework` and its symbols stay exported. The SwiftPM `-all_load` / `-force_load` retention, the CocoaPods `-all_load`, and the plugin's dead-strip keep-alive references are all removed — a loaded image needs none of them.
