[section:upgrade Upgrade version of Boost.Range]
[section:upgrade_from_1_55 Upgrade from version 1.55]
# __iterator_range__ is now implemented by implementing the member functions
`size()`, `operator[]` via inheritance of base-classes specialized by the
traversal type of the underlying iterator. This is normally requires no
alteration of code. It does mean that types that derive from iterator_range may
need to prefix `this->` to the various member functions. Additionally it has
been noted that some calling code was relying on member functions such as
`size()` being present despite the underlying iterators not being random-access
due to `iterator_reference<Iter>::type` not being a reference. The suggested
refactoring is to use `boost::size(rng)`.
[section:upgrade_from_1_49 Upgrade from version 1.49]
# __size__ now returns the type Rng::size_type if the range has size_type;
