The latest Release of GRTensorII is 1.79 for Maple 6, 7, 8, 9 and 9.5. (If you use a Microsoft operating system, make sure your maple.ini file is in the users subdirectory with Maple 7, 8 and 9.)
With Maple 8 and 9, for the current release of GRTensorII, you need to load the libraries needed for your calculation. In previous versions of Maple they autoload. A typical initialization file is here. Simply download this file and follow the instructions in it. If you have developed your own libraries, load them in the same way.

For most cases, this means that maple 6 is now likely to run out of memory (both physical and virtual) on any machine before it encounters an 'object too large' message.
This Release offers the following changes since Release 1.70:
