This is a maintenance release of uthash. See the ChangeLog for details.
Version 1.6 of uthash includes new hash functions, new HASH_CLEAR and HASH_SELECT operations, and an auxiliary linked list header utlist.h
This release of uthash supports thread-safe concurrent readers and makes HASH_FIND about 13% faster.
uthash-1.4 features C++ compatibility, an API for obtaining the count of items in the hash, greater memory efficiency and clean pedantic compilation
Performance enhancements and greater platform support are included in uthash-1.3 as well as a significantly revised User Guide.
Sorted iteration is now supported using the new HASH_SORT macro. Other changes include Cygwin support for the built-in tests and documentation enhancements.
The uthash User Guide (http://uthash.sourceforge.net/userguide.html) has been enhanced with a clickable Table of Contents.
In release 1.1, uthash now has several built-in hash functions. Choosing the right one for your key domain is easy, using the new keystats utility.
The API is now even simpler. See http://uthash.sourceforge.net for examples and the updated User Guide.
