# Changelog
## 0.7.2
**Features**:
- Add optional Gzip transport compression via build option `SENTRY_TRANSPORT_COMPRESSION`. Requires system `zlib`. ([#954](https://github.com/getsentry/sentry-native/pull/954))
- Enable automatic MIME detection of attachments sent with crash-reports from the `crashpad_handler`. ([#973](https://github.com/getsentry/sentry-native/pull/973), [crashpad#98](https://github.com/getsentry/crashpad/pull/98))
**Fixes**:
- Fix the Linux build when targeting RISC-V. ([#972](https://github.com/getsentry/sentry-native/pull/972))
**Thank you**:
- [@Strive-Sun](https://github.com/Strive-Sun)
- [@jwinarske](https://github.com/jwinarske)
## 0.7.1
**Features**:
- Add user feedback capability to the Native SDK. ([#966](https://github.com/getsentry/sentry-native/pull/966))
**Internal**:
- Remove the `CRASHPAD_WER_ENABLED` build flag. The WER module is now built for all supported Windows targets, and registration is conditional on runtime Windows version checks. ([#950](https://github.com/getsentry/sentry-native/pull/950), [crashpad#96](https://github.com/getsentry/crashpad/pull/96))
**Docs**:
- Add usage of the breadcrumb `data` property to the example. [#951](https://github.com/getsentry/sentry-native/pull/951)
## 0.7.0
**Breaking changes**:
- Make `crashpad` the default backend for Linux. ([#927](https://github.com/getsentry/sentry-native/pull/927))
- Remove build option `SENTRY_CRASHPAD_SYSTEM`. ([#928](https://github.com/getsentry/sentry-native/pull/928))
**Fixes**:
- Maintain `crashpad` client instance during Native SDK lifecycle. ([#910](https://github.com/getsentry/sentry-native/pull/910))
- Specify correct dependencies for CMake client projects using a system-provided breakpad. ([#926](https://github.com/getsentry/sentry-native/pull/926))
- Correct the Windows header include used by `sentry.h`, which fixes the build of [Swift bindings](https://github.com/thebrowsercompany/swift-sentry). ([#935](https://github.com/getsentry/sentry-native/pull/935))
**Internal**:
- Updated `crashpad` to 2023-11-24. ([#912](https://github.com/getsentry/sentry-native/pull/912), [crashpad#91](https://github.com/getsentry/crashpad/pull/91))
- Fixing `crashpad` build for Windows on ARM64. ([#919](https://github.com/getsentry/sentry-native/pull/919), [crashpad#90](https://github.com/getsentry/crashpad/pull/90), [crashpad#92](https://github.com/getsentry/crashpad/pull/92), [crashpad#93](https://github.com/getsentry/crashpad/pull/93), [crashpad#94](https://github.com/getsentry/crashpad/pull/94))
- Remove options memory leak during consent setting. ([#922](https://github.com/getsentry/sentry-native/pull/922))

Features, fixes and improvements in this release have been contributed by:

- [@hyp](https://github.com/hyp)
## 0.6.7
**Fixes**:
- Disable sigaltstack on Android ([#901](https://github.com/getsentry/sentry-native/pull/901))
- Prevent stuck crashpad-client on Windows ([#902](https://github.com/getsentry/sentry-native/pull/902), [crashpad#89](https://github.com/getsentry/crashpad/pull/89))

### Note <!-- omit in toc -->
Using the `sentry-native` SDK in a standalone use case is currently an experimental feature. The SDKs primary function is to fuel our other SDKs, like [`sentry-java`](https://github.com/getsentry/sentry-java) or [`sentry-unreal`](https://github.com/getsentry/sentry-unreal). Support from our side is best effort and we do what we can to respond to issues in a timely fashion, but please understand if we wont be able to address your issues or feature suggestions.

This instructs the build system to use system-installed breakpad or crashpad
libraries instead of using the in-tree version. This is generally not recommended
for crashpad, as sentry uses a patched version that has attachment support.
This is being worked on upstream as well, and a future version might work with
an unmodified crashpad version as well.

This instructs the build system to use system-installed breakpad libraries instead of using the in-tree version.

// A span is a value type that represents an array of elements of type T. Since
// it only consists of a pointer to memory with an associated size, it is very
// light-weight. It is cheap to construct, copy, move and use spans, so that
// users are encouraged to use it as a pass-by-value parameter. A span does not
// own the underlying memory, so care must be taken to ensure that a span does
// not outlive the backing store.
//
// span is somewhat analogous to StringPiece, but with arbitrary element types,
// allowing mutation if T is non-const.
//
// span is implicitly convertible from C++ arrays, as well as most [1]
// container-like types that provide a data() and size() method (such as
// std::vector<T>). A mutable span<T> can also be implicitly converted to an
// immutable span<const T>.
//
// Consider using a span for functions that take a data pointer and size
// parameter: it allows the function to still act on an array-like type, while
// allowing the caller code to be a bit more concise.
//
// For read-only data access pass a span<const T>: the caller can supply either
// a span<const T> or a span<T>, while the callee will have a read-only view.
// For read-write access a mutable span<T> is required.
//
// Without span:
// Read-Only:
// // std::string HexEncode(const uint8_t* data, size_t size);
// std::vector<uint8_t> data_buffer = GenerateData();
// std::string r = HexEncode(data_buffer.data(), data_buffer.size());
//
// Mutable:
// // ssize_t SafeSNPrintf(char* buf, size_t N, const char* fmt, Args...);
// char str_buffer[100];
// SafeSNPrintf(str_buffer, sizeof(str_buffer), "Pi ~= %lf", 3.14);
//
// With span:
// Read-Only:
// // std::string HexEncode(base::span<const uint8_t> data);
// std::vector<uint8_t> data_buffer = GenerateData();
// std::string r = HexEncode(data_buffer);
//
// Mutable:
// // ssize_t SafeSNPrintf(base::span<char>, const char* fmt, Args...);
// char str_buffer[100];
// SafeSNPrintf(str_buffer, "Pi ~= %lf", 3.14);
//
// Spans with "const" and pointers
// -------------------------------
//
// Const and pointers can get confusing. Here are vectors of pointers and their
// corresponding spans:
//
// const std::vector<int*> => base::span<int* const>
// std::vector<const int*> => base::span<const int*>
// const std::vector<const int*> => base::span<const int* const>
//
// Differences from the C++20 draft
// --------------------------------
//
// http://eel.is/c++draft/views contains the latest C++20 draft of std::span.
// Chromium tries to follow the draft as close as possible. Differences between
// the draft and the implementation are documented in subsections below.
//
// Differences from [span.objectrep]:
// - as_bytes() and as_writable_bytes() return spans of uint8_t instead of
// std::byte (std::byte is a C++17 feature)
//
// Differences from [span.cons]:
// - Constructing a static span (i.e. Extent != dynamic_extent) from a dynamic
// sized container (e.g. std::vector) requires an explicit conversion (in the
// C++20 draft this is simply UB)
//
// Furthermore, all constructors and methods are marked noexcept due to the lack
// of exceptions in Chromium.
//
// Due to the lack of class template argument deduction guides in C++14
// appropriate make_span() utility functions are provided.

// std::string result = base::StrCat({"foo ", result, "\nfoo ", bar});
//
// MORE INFO
//
// StrCat can see all arguments at once, so it can allocate one return buffer
// of exactly the right size and copy once, as opposed to a sequence of
// operator+ which generates a series of temporary strings, copying as it goes.
// And by using StringPiece arguments, StrCat can avoid creating temporary
// string objects for char* constants.
//
// ALTERNATIVES
//
// Internal Google / Abseil has a similar StrCat function. That version takes
// an overloaded number of arguments instead of initializer list (overflowing
// to initializer list for many arguments). We don't have any legacy
// requirements and using only initializer_list is simpler and generates
// roughly the same amount of code at the call sites.
//
// Abseil's StrCat also allows numbers by using an intermediate class that can
// be implicitly constructed from either a string or various number types. This
// class formats the numbers into a static buffer for increased performance,
// and the call sites look nice.
//
// As-written Abseil's helper class for numbers generates slightly more code
// than the raw StringPiece version. We can de-inline the helper class'
// constructors which will cause the StringPiece constructors to be de-inlined
// for this call and generate slightly less code. This is something we can
// explore more in the future.
