+## 3.12.3
+- Fix (Windows): example `Generate` was requesting an RSA-2048 encryption subkey alongside an EdDSA primary key; switched to plain EdDSA+ECDH, which eliminates the 30 s FFI timeout on slow CI runners
+- Fix (iOS CI): add a 3-attempt retry loop (7 min per attempt) around `flutter test` to recover from the intermittent VM-Service hang (flutter/flutter#160930); `timeout-minutes: 30` on every job caps run cost
+- Fix (web CI): bump web plugin operation timeout 30 s → 120 s; fix `flutter drive` failure-detection grep to catch `"Failure Details:"` in addition to `❌`; `Generate` remains skipped on web (debug-mode Go WASM keygen exceeds 120 s on CI runners even for ECC keys; 9 other crypto operations still run as real web coverage)
+
+## 3.12.2
+- CI: bump `actions/checkout` v4 → v6.0.2 across every workflow
+- CI (iOS): deterministically select the newest installed iOS runtime's iPhone (the runner ships multiple runtimes, so "iPhone 16" alone matched more than one device); add `wait_for_boot`; drop the `nick-fields/retry` wrapper and ASCII-only result matching so the job mirrors the other platforms
+- CI (web): replace the build-only smoke test with real integration tests run in headless Chrome via `chromedriver` + `flutter drive` (the `Generate` test is skipped on web — RSA-2048 keygen in the Go WASM build exceeds the 30s operation timeout on CI runners)
+- Example: remove leftover CocoaPods integration from the iOS and macOS projects; they are now Swift Package Manager only (the macOS app keeps the `[Custom] Embed libopenpgp_bridge.dylib` build phase, since SPM links but does not embed the bare dylib)
+
+## 3.12.1
+- CI: update runner actions and Flutter — futureware-tech/simulator-action v1→v5, nick-fields/retry v3→v4.0.0, subosito/flutter-action pinned to v2, and Flutter pinned to 3.44.0 across all integration-test workflows
+
+## 3.12.0
+- **BREAKING:** iOS and macOS are now distributed exclusively via Swift Package Manager; the CocoaPods podspecs have been removed. Apps must run `flutter config --enable-swift-package-manager` and use **Flutter 3.41.0+ (Dart SDK 3.11+)**
+- iOS: link the static `OpenPGPBridge.xcframework` as a SwiftPM `binaryTarget`; `OpenPGPBridgeCall` is resolved at runtime via `DynamicLibrary.process()`, so `OpenpgpPlugin.keepBridgeSymbols()` keeps it from being dead-stripped and `-export_dynamic` exports it into the app's dynamic symbol table for `dlsym`
+- macOS: wrap `libopenpgp_bridge.dylib` into `macos/openpgp/OpenPGPBridge.xcframework` (via `scripts/build_macos_xcframework.sh`) so SPM can embed and code-sign it; the Build Native Libs workflow rebuilds and commits it alongside the other binaries
+- Relocate plugin sources to the Swift Package layout (`<platform>/openpgp/Sources/openpgp/`) with each `OpenPGPBridge.xcframework` inside its package directory (Flutter copies SwiftPM packages to an ephemeral location, so `binaryTarget` paths must be package-relative)
+- CI: SPM-only iOS and macOS integration tests; the iOS job retries past Flutter's intermittent simulator "Waiting for VM Service" hang (flutter/flutter#160930) by rebooting the simulator between attempts
+- Set the example app `version` so iOS builds no longer warn about missing `CFBundleShortVersionString`/`CFBundleVersion`
+
+## 3.11.2
+- Fix iOS integration tests: pin CI runner to macos-14, add `-d "iPhone 16"` device flag, add 30-minute step timeout, pin flutter-action to v2
+- Fix memory leaks in iOS plugin: removed redundant nil-arg C calls from `init` handler (force_load in podspec already prevents symbol stripping)
+- Fix `callAsync` hanging forever when worker isolate crashes silently: now throws after 30s timeout
+- Add `OpenPGPFreeResult` CGo export to eliminate cross-allocator free on Windows; Dart uses it when available with fallback for older builds
+- Fix `ffi.dart`: add `FreeResultC`/`FreeResultDart` typedefs for `OpenPGPFreeResult`
+
+## 3.11.0
+- Rebuild all native libs with post-quantum cryptography support (ML-DSA-65 / ML-KEM-768)
+- Unified Windows DLL build into the main native libs workflow (single CI pipeline for all platforms)
+- Fixed macOS integration tests in CI (pin runner to macos-14 for CVDisplayLink compatibility)
+- Fixed iOS integration tests in CI (pin simulator to iPhone 16; add step timeout)
+- Fixed macOS dylib codesigning and install name for CI embed
+- Upgraded example transitive dependencies
+
 ## 3.10.7
 - Add force load to prevent stripping

+## Post-Quantum Cryptography
+
+This library supports the four composite PQC algorithms introduced in GnuPG 2.5.x, implemented via FIPS 203 (ML-KEM) and FIPS 204 (ML-DSA):
+
+| Algorithm enum | GnuPG name | Description |
+|---|---|---|
+| `Algorithm.MLDSA65ED25519` | `dil3x25519` | ML-DSA-65 + Ed25519 signing key (OpenPGP v6) |
+| `Algorithm.MLDSA87ED448` | `dil5x448` | ML-DSA-87 + Ed448 signing key (OpenPGP v6) |
+| `Algorithm.MLKEM768X25519` | `ky768x25519` | ML-KEM-768 + X25519 encryption key |
+| `Algorithm.MLKEM1024X448` | `ky1024x448` | ML-KEM-1024 + X448 encryption key (OpenPGP v6) |
+
+ML-DSA keys are signing keys that automatically include a matching ML-KEM encryption subkey. ML-KEM keys are encryption keys that automatically include an Ed25519/Ed448 primary signing key.
+
+```dart
+void main() async {
+  // Generate a post-quantum signing + encryption key pair
+  var keyPair = await OpenPGP.generate(
+    options: Options()
+      ..name = 'Alice'

+      ..keyOptions = (KeyOptions()..algorithm = Algorithm.MLDSA65ED25519),
+  );
+
+  // Works with all existing encrypt/decrypt/sign/verify operations
+  var encrypted = await OpenPGP.encrypt("hello", keyPair.publicKey);

+### Swift Package Manager (iOS & macOS)
+
+The iOS and macOS plugins are distributed **exclusively via Swift Package Manager** —
+there are no CocoaPods podspecs. This requires **Flutter 3.41.0 or higher** with Swift
+Package Manager enabled.
+
+#### For app developers
+
+Swift Package Manager is off by default, so enable it once:
+
+```bash
+flutter config --enable-swift-package-manager
+```
+
+Then `flutter pub get` and build/run as usual — the prebuilt Go bridge is linked and
+embedded automatically. If SPM is left disabled, Flutter stays in CocoaPods mode and
+will not find this plugin's iOS/macOS implementation.
+
+> **Note for `path:`/`git:` (non-hosted) dependencies:** Flutter derives a plugin's
+> SwiftPM package identity from the Dart-package root directory name, which must equal
+> the plugin name. If you depend on this plugin from a checkout whose folder is not
+> named `openpgp` (for example the repository folder `flutter-openpgp`), SPM fails with
+> `unable to override package 'openpgp' ... identity 'flutter-openpgp'`. Use it from
+> pub.dev (hosted), or check it out into a folder named `openpgp`. Normal `pub.dev`
+> installs are unaffected.
+
+#### For plugin contributors
+
+```
+ios/
+  openpgp/
+    Package.swift
+    Sources/openpgp/OpenpgpPlugin.swift
+    OpenPGPBridge.xcframework          # prebuilt static bridge (committed by Build Native Libs)
+macos/
+  libopenpgp_bridge.dylib              # prebuilt dynamic bridge (build input)
+  openpgp/
+    Package.swift
+    Sources/openpgp/OpenpgpPlugin.swift
+    OpenPGPBridge.xcframework          # built from the dylib, committed for SPM
+```
+
+The xcframework must sit *inside* each `openpgp/` package directory (not in the
+platform root): Flutter copies the SwiftPM package into an ephemeral `.packages/`
+location at build time, so the `binaryTarget` path has to be package-relative.
+
+- **iOS** links the static `OpenPGPBridge.xcframework` as a SwiftPM `binaryTarget`. The
+  Go entry point `OpenPGPBridgeCall` is resolved at runtime via
+  `DynamicLibrary.process()`, so the iOS `Package.swift` (a) keeps a reachable
+  reference via `OpenpgpPlugin.keepBridgeSymbols()` so the linker does not strip it, and
+  (b) passes `-export_dynamic` so the symbol lands in the app's dynamic symbol table for
+  `dlsym`.
+- **macOS** ships a dynamic `libopenpgp_bridge.dylib`; SwiftPM cannot embed a loose
+  dylib, so `scripts/build_macos_xcframework.sh` wraps it into
+  `macos/openpgp/OpenPGPBridge.xcframework`. The Build Native Libs workflow rebuilds
+  every platform's bridge and commits them all (including this xcframework), so the
+  committed artifacts are exactly what consumers resolve.
