The C++ Standards Committee tends to shy away from adding new keywords to the language, yet with C++11 that was not the case. Some examples:
constexpr
decltype
thread_local
auto // New usage
noexcept
nullptr
static_assert
alignof
alignas
Are there any new keywords introduced with C++14?
Table 4 (Keywords) in N3936 (C++14):
alignas continue friend register true
alignof decltype goto reinterpret_cast try
asm default if return typedef
auto delete inline short typeid
bool do int signed typename
break double long sizeof union
case dynamic_cast mutable static unsigned
catch else namespace static_assert using
char enum new static_cast virtual
char16_t explicit noexcept struct void
char32_t export nullptr switch volatile
class extern operator template wchar_t
const false private this while
constexpr float protected thread_local
const_cast for public throw
Table 4 in N3337 (C++11):
alignas continue friend register true
alignof decltype goto reinterpret_cast try
asm default if return typedef
auto delete inline short typeid
bool do int signed typename
break double long sizeof union
case dynamic_cast mutable static unsigned
catch else namespace static_assert using
char enum new static_cast virtual
char16_t explicit noexcept struct void
char32_t export nullptr switch volatile
class extern operator template wchar_t
const false private this while
constexpr float protected thread_local
const_cast for public throw
...which is a long-winded way of saying "no".
(override
and final
are "identifiers with special meaning" and are listed in Table 3; and
etc. are "alternative representations...for certain operators and punctuators" and are listed in Table 5. Neither table changed between C++11 and C++14.)
