10 | | -Visual Studio 2022 brings many updates and fixes to the Microsoft C++ environment. We've added features and fixed many bugs and issues in the compiler and tools. The Visual Studio IDE also offers significant improvements in performance and productivity, and now runs natively as a 64-bit application. For more information on what's new in all of Visual Studio, visit [What's new in Visual Studio 2022](/visualstudio/ide/whats-new-visual-studio-2022?view=vs-2022&preserve-view=true). For information about what's new in the C++ docs, see [Microsoft C++ docs: What's new](whats-new-cpp-docs.md). |

| 14 | +## What's new for C++ in Visual Studio version 17.4 |
| 15 | + |
| 16 | +For a summary of new features and bug fixes in Visual Studio in version 17.34, see [Visual Studio 2022 version 17.3 Release Notes](/visualstudio/releases/2022/release-notes-v17.4). |
| 17 | + |
| 18 | +- Improved compiler error messages to provide more correct and useful information, especially for concepts. |
| 19 | + |
| 20 | +- Added experimental MSVC flag **`/experimental:log<directory>`** to output SARIF build logs to the specified directory. |
| 21 | + |
| 22 | +- Added support for C23 attributes to IntelliSense and continued progress in C++20 modules support. |
| 23 | + |
| 24 | +- Improved indexing performance when opening a new solution. Large projects could see a 20-35% improvement from 17.3. |
| 25 | + |
| 26 | +- Improved Named Return Value Optimization (NRVO): |
| 27 | + - NRVO is enabled for cases that involve exception handling or loops. |
| 28 | + - NRVO is enabled even under **`/Od`** if the user passes the **`/Zc:nrvo`** flag, or **`/std:c++20`** or later, or **`/permissive-`**. |
| 29 | + - You can now disable NRVO with the **`/Zc:nrvo-`** flag. |
| 30 | + |
| 31 | +- Upgraded the version of LLVM shipped with Visual Studio to 15.0.1. For more information on what is available, see the [LLVM](https://releases.llvm.org/15.0.0/docs/ReleaseNotes.html) and [Clang](https://releases.llvm.org/15.0.0/tools/clang/docs/ReleaseNotes.html) release notes. |
| 32 | + |
| 33 | +- Added support to Visual Studio for vcpkg artifacts with CMake projects. For projects that include a vcpkg manifest, the environment is activated automatically on project open. Learn more about this feature in the [vcpkg environment activation in Visual Studio](https://aka.ms/vsvcpkgenv) blog post. |
| 34 | + |
| 35 | +- You can now use Dev Containers for your C++ projects. Learn more about this feature in our [Dev Containers for C++](https://aka.ms/vscppdevcontainer) blog post. |
| 36 | + |
| 37 | +- IntelliSense now respects the order of pre-included headers when one is a PCH. Previously, when a PCH was used via **`/Yu`** and force-included via **`/FI`**, IntelliSense would always process it first, before any other headers included via **`/FI`**. This behavior didn't match the build behavior. With this change, **`/FI`** headers are processed in the order they're specified. |
| 38 | + |
| 39 | +- Removed internal prefixes from CTest names in Test Explorer. |
| 40 | + |
| 41 | +- Updated the version of CMake shipped with Visual Studio to version 3.24.1. For details of what is available, see the [CMake release notes](https://cmake.org/cmake/help/v3.24/release/3.24.html). |
| 42 | + |
| 43 | +- Android SDK update: |
| 44 | + - Ant scripts have been removed, so users will no longer see Ant-based templates in the New Project dialog. For help migrating from Ant templates to Gradle templates, see [Migrating Builds From Apache Ant](https://docs.gradle.org/current/userguide/migrating_from_ant.html) |
| 45 | + - Added support for building with NDK 23 and 24 |
| 46 | + - Updated NDK component to the LTS version 23 |
| 47 | + |
| 48 | +- Added vectorized implementations of `ranges::min_element()`, `ranges::max_element()`, and `ranges::minmax_element()` |
| 49 | + |
| 50 | +- We continue to track the latest developments in C++ standardization. Support for these C++23 features is available by including [`/std:c++latest`](../build/reference/std-specify-language-standard-version.md) in your compiler options: |
| 51 | + - [P2302R4](https://wg21.link/p2302r4) `ranges::contains`, `ranges::contains_subrange` |
| 52 | + - [P2499R0](https://wg21.link/p2499r0) `string_view` Range Constructor Should Be `explicit` |
| 53 | + - [P0849R8](https://wg21.link/p0849r8) `auto(x)`: decay-copy In The Language |
| 54 | + |
| 55 | + (The compiler part isn't implemented yet. The library part was implemented in C++20 mode when Ranges support was initially implemented.) |
| 56 | + - [P0881R7](https://wg21.link/p0881r7) `<stacktrace>` |
| 57 | + - [P2301R1](https://wg21.link/p2301r1) Add A `pmr` Alias For `std::stacktrace` |
| 58 | + - [P1328R1](https://wg21.link/p1328r1) `constexpr type_info::operator==()` |
| 59 | + - [P2440R1](https://wg21.link/p2440r1) `ranges::iota`, `ranges::shift_left`, `ranges::shift_right` |
| 60 | + - [P2441R2](https://wg21.link/p2441r2) `views::join_with` |
| 61 | + |
| 62 | +- Added an option "Navigation after Create Declaration/Definition" to allow you to choose the navigation behavior of the Create Declaration/Definition feature. You can select between peeking (the default) or opening the document, or no navigation. |
| 63 | + |
| 64 | +- Arm64 builds of Visual Studio now bundle Arm64 versions of CMake and Ninja. |
| 65 | + |
| 66 | +- Added support for CMake Presets version 4. For details of what is available, see the [CMake release notes](https://cmake.org/cmake/help/v3.23/release/3.23.html#id6). |
| 67 | + |
| 68 | +- Remote system connections using the [Connection Manager](../linux/connect-to-your-remote-linux-computer.md) now support SSH ProxyJump. ProxyJump is used to access an SSH host via another SSH host (for example, to access a host behind a firewall). |
