+### 0.11.0
+
+**Breaking changes**:
+
+- Add `user_data` parameter to `traces_sampler`. ([#1346](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1346))
+
+**Fixes**:
+
+- Include `stddef.h` explicitly in `crashpad` since future `libc++` revisions will stop providing this include transitively. ([#1375](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1375), [crashpad#132](https://github-redirect.dependabot.com/getsentry/crashpad/pull/132))
+- Fall back on `JWASM` in the _MinGW_ `crashpad` build only if _no_ `CMAKE_ASM_MASM_COMPILER` has been defined. ([#1375](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1375), [crashpad#133](https://github-redirect.dependabot.com/getsentry/crashpad/pull/133))
+- Prevent `crashpad` from leaking Objective-C ARC compile options into any parent target linkage. ([#1375](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1375), [crashpad#134](https://github-redirect.dependabot.com/getsentry/crashpad/pull/134))
+- Fixed a TOCTOU race between session init/shutdown and event capture. ([#1377](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1377))
+- Make the Windows resource generation aware of config-specific output paths for multi-config generators. ([#1383](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1383))
+- Remove the `ASM` language from the top-level CMake project, as this triggered CMake policy `CMP194` which isn't applicable to the top-level. ([#1384](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1384))
+
+**Features**:
+
+- Add a configuration to disable logging after a crash has been detected - `sentry_options_set_logger_enabled_when_crashed()`. ([#1371](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1371))
+
+**Internal**:
+
+- Support downstream Xbox SDK specifying networking initialization mechanism. ([#1359](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1359))
+- Added `crashpad` support infrastructure for the external crash reporter feature. ([#1375](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1375), [crashpad#131](https://github-redirect.dependabot.com/getsentry/crashpad/pull/131))
+
+**Docs**:
+
+- Document the CMake 4 requirement on macOS `SDKROOT` due to its empty default for `CMAKE_OSX_SYSROOT` in the `README`. ([#1368](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1368))
+
+**Thank you**:
+
+- [JanFellner](https://github-redirect.dependabot.com/JanFellner)
+
+### 0.10.1
+
+**Internal**:
+
+- Correctly apply dynamic mutex initialization in unit-tests (fixes running unit-tests in downstream console SDKs). ([#1337](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1337))
+
+### 0.10.0
+
+**Breaking changes**:
+
+- By using transactions as automatic trace boundaries, transactions will, by default, no longer be part of the same singular trace. This is not the case when setting trace boundaries explicitly (`sentry_regenerate_trace()` or `sentry_set_trace()`), which turns off the automatic management of trace boundaries. ([#1270](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1270))
+- Change transaction sampling to be trace-based. This does not affect you when transactions are used for automatic trace boundaries (as described above), since every transaction is part of a new trace. However, if you manage trace boundaries manually (using `sentry_regenerate_trace()`) or run the Native SDK inside a downstream SDK like the Unity SDK, where these SDKs will manage the trace boundaries, for a given `traces_sample_rate`, either all transactions in a trace get sampled or none do with probability equal to that sample rate. ([#1254](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1254))
+- Moved Xbox toolchains to an Xbox-specific repository [sentry-xbox](https://github-redirect.dependabot.com/getsentry/sentry-xbox). You can request access to the repository by following the instructions in [Xbox documentation](https://docs.sentry.io/platforms/xbox/). ([#1329](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1329))
+
+**Features**:
+
+- Add `sentry_clear_attachments()` to allow clearing all previously added attachments in the global scope. ([#1290](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1290))
+- Automatically set trace boundaries with every transaction. ([#1270](https://github-redirect.dependabot.com/getsentry/sentry-native/pull/1270))

Subject: [PATCH 06/13] fix: handle git diff exit codes properly in PowerShell
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

- Add proper error action preference settings to match CI environment
- Handle git diff exit code 1 (differences found) as expected behavior
- Use explicit exit 0 to ensure clean script termination
- Fixes updater-pr-creation CI failures with PSNativeCommandErrorActionPreference
