Released another updated version 0.8.3 of the STX B+ Tree C++ Template Classes package. The updated release fixes up issues with the root node == NULL when the tree is initially empty.

Fixed crash when running verify() on an empty btree object. Now the root node is freed when the last item is removed. Also fixed crash when attempting to copy an empty btree or when trying to remove a non-existing item from an empty btree.

Also enhancing the speedtest to test the hash table container implementation from __gnu_cxx. Extending tests by another set of runs measuring only the find/lookup functions. See the speed results web page for more information.

The updated source code package is available for download from this webpage.

Some compiled binaries of wxBTreeDemo for Win32 and Linux are available on the demo download page.

As before, the updated main B+ tree implementation can be found in doxygen stx/btree.h or with plain text comments stx/btree.h.
