	English Storing an object in an unordered associative container requires both a key equality function and a hash function. The default function objects in the standard containers support a few basic types including integer types, floating point types, pointer types, and the standard strings. Since Boost.Unordered uses link:../../../../container_hash/index.html[boost::hash^] it also supports some other types, including standard containers. To use any types not supported by these methods you have to extend Boost.Hash to support the type or use your own custom equality predicates and hash functions. See the xref:hash_equality.adoc#hash_equality[Equality Predicates and Hash Functions], section for more details. 708/10000 · 708

	English Added GDB pretty-printers for all containers and iterators. For a container with an allocator that uses fancy pointers, these only work if the proper pretty-printer is written for the fancy pointer type itself. 210/10000 · 210
