**Affected:** [[library]] – [[thread]] **Change:** New reserved

identifiers. **Rationale:** Required by new features. **Effect on

**Change:** New headers. **Rationale:** New functionality. **Effect on
|
| 12 |
original feature:** The following C++ headers are new: `<array>`,
|
| 13 |
`<atomic>`, `<chrono>`, , `<condition_variable>`, `<forward_list>`,
|
| 14 |
`<future>`, `<initializer_list>`, `<mutex>`, `<random>`, `<ratio>`,
|
| 15 |
`<regex>`, `<scoped_allocator>`, `<system_error>`, `<thread>`,
|
| 16 |
`<tuple>`, `<typeindex>`, `<type_traits>`, `<unordered_map>`, and
|
| 17 |
`<unordered_set>`. In addition the following C compatibility headers are
|
| 18 |
new: `<cfenv>`, `<cinttypes>`, `<cstdint>`, and `<cuchar>`. Valid C++03
|

code that `#include`s headers with these names may be invalid in this

**Effect on original feature:** Function `swap` moved to a different
|
| 23 |
header **Rationale:** Remove dependency on `<algorithm>` for `swap`.
|
| 24 |
**Effect on original feature:** Valid C++03 code that has been compiled
|
| 25 |
expecting swap to be in `<algorithm>` may have to instead include
|

`<utility>`.

**Change:** New reserved namespace. **Rationale:** New functionality.
|

**Effect on original feature:** The global namespace `posix` is now
|
| 30 |
reserved for standardization. Valid C++03 code that uses a top-level
|
| 31 |
-
namespace `posix` may be invalid in this
|

|

**Change:** Additional restrictions on macro names. **Rationale:** Avoid
|
| 34 |
hard to diagnose or non-portable constructs. **Effect on original
|
| 35 |
feature:** Names of attribute identifiers may not be used as macro
|
| 36 |
names. Valid C++03 code that defines `override`, `final`,
|
| 37 |
`carries_dependency`, or `noreturn` as macros is invalid in this
