 # Changelog
 
+## Unreleased
+
+### Breaking Changes
+
+- Moves `SentryEventDecoder` to SPI (#6365)
+- Makes `PreviewRedactOptions`, `SentryProfileOptions`, `SentryRedactViewHelper`, `SentryViewScreenshotOptions`, `SentryReplayOptions`, `SentryUserFeedbackConfiguration`, `SentryUserFeedbackFormConfiguration`, `SentryUserFeedbackThemeConfiguration`, `SentryUserFeedbackWidgetConfiguration`, `SentryFeedback`, and `SentryExperimentalOptions` `final` (#6365)
+- Removes Decodable conformances from the public API of model classes (#5691)
+- Removes unused SentryLogLevel (#5591)
+- Removes deprecated `setExtraValue` from SentrySpan (#5864)
+- Removes deprecated getStoreEndpoint (#5591)
+- Remove legacy profiling, the only supported profiling is now what was known as continuous V2 (#6386)
+- Removes deprecated useSpan function (#5591)
+- Makes app hang tracking V2 the default and removes the option to enable/disable it (#5615)
+- Removes initializers for SentryTraceContext from the public API (#6662)
+- Removes `integrations` property from `SentryOptions` (#5749)
+- Removes `defaultIntegrations` function from `SentryOptions` (#6664)
+- Makes `SentryEventDecodable` internal (#5808)
+- The `span` property on `SentryScope` is now readonly (#5866)
+- Removes `SentryIntegrationProtocol` from the API. This is not used after the removal of the `integrations` property (#6660)
+- Removes deprecated SentryDebugImageProvider class (#5598)
+- Properties on SentryOptions that had no effect on the WithoutUIKit variant are now removed from the API (#6644)
+- Removes the SentryOptions.inAppExclude property because it had no effect (#6646)
+- Removes segment property on SentryUser, SentryBaggage, and SentryTraceContext (#5638)
+- Removes deprecated TraceContext initializers (#6348)
+- Removes deprecated user feedback API, this is replaced with the new feedback API (#5591)
+- Removes `enablePerformanceV2` option and makes this the default. The app start duration will now finish when the first frame is drawn instead of when the OS posts the UIWindowDidBecomeVisibleNotification. (#6008)
+- Removes enableTracing property from SentryOptions (#5694)
+- Structured Logs: Move options out of experimental (#6359)
+- Remove unused `SentryFrame.instruction` property (#6504)
+- Remove `uuid` and `name` of `SentryDebugMeta` (#6512) Use `debugID` instead of `uuid` and `codeFile` instead of `name`.
+- Enable enablePreWarmedAppStartTracing by default (#6508). With this option enabled, the SDK collects [prewarmed app starts](https://docs.sentry.io/platforms/apple/tracing/instrumentation/automatic-instrumentation/#prewarmed-app-start-tracing).
+- Set `SentryFrame.function` default to `nil` instead of `<redacted>` (#6608)
+- Change `value` and `type` of `SentryException` to be nullable (#6563)
+- Change the default trace context status to "ok" instead of "undefined" (#6611)
+- Remove `getHash` from SentryDsn (#6605)
+- The precompiled XCFramework is now built with Xcode 16. To submit to the App Store, [Apple now requires Xcode 16](https://developer.apple.com/news/upcoming-requirements/?id=02212025a).
+  If you need a precompiled XCFramework built with Xcode 15, continue using Sentry SDK 8.x.x.
+- Set `SentryException.type` to `nil` when `NSException` has no `reason` (#6653). The backend then can provide a proper message when there is no reason.
+- Rename `SentryLog.Level` and `SentryLog.Attribute` for ObjC (#6666)
+
+### Fixes
+
+- Fixes warnings about minimum OS version being lower than Xcode supported version (#5591)
+- Fixes a crash when setting configureUserFeedback to nil (#6642)
+- Fix issue where the thread that generated an event could be missing when more than 100 threads are running (#6377)
+- Fix wrong Frame Delay when becoming active, which lead to false reported app hangs when the app moves to the foreground after being in the background (#6381)
+- Rename `SentryMechanismMeta` to `SentryMechanismContext` to resolve Kotlin Multi-Platform build errors (#6607)
+
+### Improvements
+
+- Replace deprecated SCNetworkReachability with NWPathMonitor (#6019)
+- Expose attachment type on `SentryAttachment` for downstream SDKs (like sentry-godot) (#6521)
+- Increase attachment max size to 100MB (#6537)
+
+### Features
+
+- Add SentryDistribution as Swift Package Manager target (#6149)
+- Moves SentryClient and SentryHub to be written in Swift (#6627)
+- Add option `enablePropagateTraceparent` to support OTel/W3C trace propagation (#6356)
+- Move `enableFileManagerSwizzling` from experimental options to top-level options (#6592).
+  This option is still disabled by default and will be enabled in a future major release.
+- Move `enableDataSwizzling` from experimental options to top-level options (#6592). This option remains enabled by default.
+- Add `sentry.replay_id` attribute to logs ([#6515](https://github.com/getsentry/sentry-cocoa/pull/6515))
+- Structured Logs: Add `SentrySwiftLog` Integration (#6286)
