+# Changelog
+
+All notable changes to this package are documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [5.0.0] - Unreleased
+
+Upgrading from 4.x? See [Migrating from 4.x](README.md#migrating-from-4x).
+
+### Added
+
+- **Native Windows crash reporting** via [bugsplat-windows](https://github.com/BugSplat-Git/bugsplat-windows). Unity P/Invokes the SDK's `BugSplat_*` C API exports from `BugSplat.dll`, so native crashes are captured with **both the Mono and IL2CPP** scripting backends, on x86 (32-bit), x64, and ARM64. Enable it with `BugSplatOptions.UseNativeCrashReportingForWindows`. Binaries come from the official signed bugsplat-windows v8.1.0 release.
+- `BugSplatOptions.WindowsShowCrashDialog` — show the BugSplat crash dialog when a native crash occurs on Windows. Defaults to `true`; disable it to upload silently.
+- `BugSplatOptions.WindowsHangDetectionTimeoutMs` — out-of-process hang detection for Windows. Defaults to `0` (disabled). When a hang is detected, BugSplat uploads a hang report and terminates the process, so choose a timeout longer than your longest expected frame.
+- **Windows Error Reporting coverage** for fail-fast terminations — stack buffer overrun (`0xC0000409`), heap corruption (`0xC0000374`), and `__fastfail` — which bypass every in-process exception filter. Capture requires an `HKLM\...\RuntimeExceptionHelperModules` value naming `BugSplatWer.dll`:
+  - `BugSplat.WindowsWerEnabled` reports whether the handler actually registered, and init logs what is lost and how to fix it when it hasn't (a warning in development builds, informational otherwise).
+  - **BugSplat > Windows > Register WER Handler**, **Unregister WER Handler**, and **Check WER Handler Registration** write and verify that value elevated for a built player, in both registry views.
+- Unsent native Windows crash reports are uploaded automatically at startup; init also attaches `Player.log` and syncs attributes, user, email, key, description, and notes to the native reporter.
+- **Capture of unhandled exceptions thrown on background threads.** Unity only raises `logMessageReceived` for main-thread logs, so these were previously written to the player log and never reported. Background exceptions are buffered in a bounded (64-slot) thread-safe queue and posted from the main thread on the next frame, with main-thread logs rejected by thread id so nothing reports twice. On by default; opt out via **Capture Exceptions On Background Threads** on `BugSplatManager`.
+- Editor menu for symbol upload credentials: **BugSplat > Symbol Upload > Set Credentials**, **Clear Credentials**, and **Check Credentials**.
+- `Description`, `Email`, `Key`, `Notes`, and `User` gained getters — they were previously set-only.
+- Continuous integration (`.github/workflows/tests.yml`): the test suite runs on StandaloneLinux64, StandaloneWindows64, StandaloneOSX, and WebGL, plus player-script compile checks for iOS and Android that cover the code behind `!UNITY_EDITOR`, which tests cannot link against.
+- Test coverage for the `CreateFromOptions` mapping, `CopyLogTailToTempFile`, the background log message queue, and `BugSplatManager` wiring.
+- The `my-unity-crasher` sample is now a platform-aware crash scenario menu, grouped by the mechanism expected to capture each row (`MANAGED`, `NATIVE`, `FAIL-FAST`, `HANG`, `FEEDBACK`), with sections compiled per build target. Native rows are inert in the editor, and `FAIL-FAST` rows grey out when the WER handler isn't registered. No crasher DLL is shipped — every trigger is C# plus P/Invokes into system DLLs.
+
+### Changed
+
+- **Breaking:** `BugSplatOptions.Attributes` is now `List<BugSplatAttribute>` instead of `Dictionary<string, string>`. Unity cannot serialize a dictionary, so the field could never be authored in the inspector. Unity drops the old serialized value silently when a 4.x options asset is opened.
+- **Breaking:** the symbol upload environment variables are renamed from `BUGSPLAT_CLIENT_ID`/`BUGSPLAT_CLIENT_SECRET` to `SYMBOL_UPLOAD_CLIENT_ID`/`SYMBOL_UPLOAD_CLIENT_SECRET`, the names the `symbol-upload` CLI already reads. The old names are no longer read.
+- **Breaking for coroutines that yield on `Post`:** report uploads are now awaited. `yield return Task.Run(...)` waits a single frame rather than for the task, so `yield return bugsplat.Post(ex); Application.Quit();` lost reports nondeterministically. Those coroutines now genuinely wait for the upload.
+- Response parsing and callbacks run on the main thread. They previously ran on a threadpool thread, so any callback touching a Unity API threw.
+- Symbol upload credentials are machine-local and per database, resolved from the environment first and then from `~/.bugsplat/credentials/<database>.sh`. The generated Xcode build phase sources that path from `$HOME`, so nothing project-local holds a secret.
+- `Post(FileInfo)` works on all platforms for posting your own minidump files. It was previously implemented only on Windows and WSA.
+- Editor post-build copies `BugSplatMonitor.exe`, `BugSplatRc.dll`, and `BugSplatWer.dll` next to the built Windows player, with the architecture detected from the executable's PE header, and copies `LineNumberMappings.json` for IL2CPP builds when present.
+- Log messages are filtered through the reportable-message check before a coroutine is allocated. Every log message of every type previously allocated one, with the `LogType` filter running inside it.
+
+### Removed
+
+- **Breaking:** `WindowsReporter` and `INativeCrashReporter`. Unity's `CrashReporting.crashReportFolder` minidumps are no longer read or uploaded — native Windows crashes are captured by bugsplat-windows instead.
+- **Breaking:** `PostAllCrashes`, `PostCrash`, and `PostMostRecentCrash`. Unsent native crash reports upload automatically at startup, so there is nothing to call at launch. Delete any calls to these methods.
+- **Breaking:** `BugSplatOptions.SymbolUploadClientId` and `BugSplatOptions.SymbolUploadClientSecret`. Set credentials from **BugSplat > Symbol Upload > Set Credentials**, or with the environment variables in CI.
+- Sample-only, no package API affected: the `ErrorGenerator`, `BugSplatLayoutButtons`, and `PlatformDependentObject` scripts and the `Button_ForceCrash` prefab, all superseded by the scenario menu.
+
+### Fixed
+
+- Android native crash reporting was never actually enabled — the Android init branch never set the flag every native setter guards on, so all of them silently no-oped, including the attribute-sync callback. Runtime attributes, user, email, key, and notes now reach the native reporter.
+- `SetNativeKey` had no iOS or macOS branch, so `Key` never reached Apple native reports. Both now assign bugsplat-apple's `appKey` property directly.
+- `BugSplatOptions.Attributes` were never read by `CreateFromOptions`, so attributes authored on an options asset never reached a report.
+- The test assemblies did not compile on any build target: `IClientSettingsRepository.LogFileMaxSizeMB` sat behind `#if !UNITY_WEBGL` while being used unconditionally, and `WebGLClientSettingsRepository` sat behind `#if UNITY_WEBGL` while three test files referenced it unguarded.
+- `CopyLogTailToTempFile`'s null guard dereferenced the argument it was checking.
+
+### Security
+
+- Symbol upload credentials no longer leave the developer's machine. They previously had three exits: inlined into the `/bin/sh` build phase inside `project.pbxproj`, serialized onto the `BugSplatOptions` asset and therefore into version control and shipped builds, and passed as a `--clientSecret` command-line argument visible in process listings.
+- **An iOS build phase generated before 5.0.0 contains your Client ID and Secret in plain text — rotate them.** Projects exported with Append, or checked into version control, keep the old "Upload dSYM files to BugSplat" phase; delete it and build again, or re-export with Replace.
