[section:upgrade Upgrade version of Boost.Range]
[section:upgrade_from_1_49 Upgrade from version 1.49]
# __size__ now returns the type Rng::size_type if the range has size_type;
otherwise range_size<Rng>::type is used. This is the distance type promoted to
an unsigned type.
[section:upgrade_from_1_45 Upgrade from version 1.45]
# __size__ in addition to supporting __random_access_range__ now also supports extensibility via calls to the unqualified `range_calculate_size(rng)` function.
