===== LibHFZ news =====

==== 10th of August, 2009 ====

  * Uploaded [[libhfz:downloads#v1.4.3|LibHFZ 1.4.3]], with change to implementation of [[libhfz:functions:hfzLoad]] and [[libhfz:functions:hfzLoadEx]] functions such that the file header argument is nulled with a call to [[libhfz:functions:hfzHeader_Init]] rather than [[libhfz:functions:hfzHeader_Reset]]. Callers are now responsible for ensuring that headers have been reset if they have been initialised prior to any calls to [[libhfz:functions:hfzLoad]] / [[libhfz:functions:hfzLoadEx]] (//Thanks Enge!//)
