Это которые с auto в параметрах и все такое:

Скопирую самую вкусность оттуда, для тех, у кого линк не откроется:

The current version (12/2012) implements subproposals 2.1, 2.2, 2.3 and 2.5.

2.1 Allow the type-specifier within a parameter declaration of a lambda to be auto (i.e. auto is mandatory)

auto Sum = [](auto a, decltype(a) b) { return a + b; };
int i = Sum(3, 4);
double d = Sum(3.14, 2.77);

2.2 Allow the use of familiar template syntax in lambda expressions

auto NumElements = []<int N>(auto (&a)[N]) { return N; };
int arri[]{1, 2, 3};
double arrd[]{3.14, 2.77, 6.626};
auto total = NumElements(arri) + NumElements(arrd);

2.3 Permit a lambda body to be an expression

int local = 10;
auto L = [&](auto a) a + ++local;

2.5 Autogenerate a conversion to function pointer in captureless generic lambdas

auto L = [](auto a, decltype(a) b) { return a + b; };
int (*fp)(int, int) = L;
