• rebuilt Cython wrapper with Cython 0.23.4;
• changed Trie to implement collections.abc.MutableMapping;
• fixed Trie pickling, which segfaulted on Python2.X.

• bundled libdatrie C library is updated to version 0.2.8;

• iter_prefix_values, prefix_values and longest_prefix_value methods for datrie.BaseTrie and datrie.Trie (thanks Jared Suttles).

• Recently introduced memory leak in longest_prefix and longest_prefix_item is fixed.

• longest_prefix and longest_prefix_item methods are fixed;
• datrie is rebuilt with Cython 0.18;
• misleading benchmark results in README are fixed;

There are no new features or speed improvements in this release.

• datrie.new is deprecated; use datrie.Trie with the same arguments;
• small test & benchmark improvements.

• datrie.Trie items can have any Python object as a value (Trie from 0.1.x becomes datrie.BaseTrie);
