For god sake READ THE DIRECTIONS! For OSX users, TWO updates must be implemented in a specific order. First is the OSX update, THEN the v1.10 update.
And the v1.10 updater has a slight bug, if you were a beta tester. This updater will update the beta version, instead of an older full version (i.e., 1.09). So you need to:
1) Save the character files you want to transfer from the beta version,
2) Delete (or hide in an archive) the beta version,
3) Install the OSX update over the orignal version on your HD,
4) Run the v1.10 updater
5) Copy the beta version characters in the saved folder in the orignal version.
Now for the update itself. On my 800Mz G4 it seems much faster, in OS9 and especially OSX. This is clearly apparent when the automap feature is off. So far it seem stable as a rock. A significant improvement for OSX. The changes seem to have even out the character classes a lot and the impoved interaction between the various skills is a nice enhancement.
Overall, major improvements in stability and speed (especially if you are using Jaguar). Game play modifications are not as signficant, makes Sorceress and Amazon slightly less powerful but slight enhancement to the other classes. I think the game play changes are a nice tweak, but if speed and stability are currently satisfactory then this update is a take it or leave it.
