Yay! Now it is finally here! Version 3.1 of my pathfinding system.
The upgrade should be hassle free (hopefully). However ListGraphs will not have their settings preserved. This is because I have renamed the ListGraph to PointGraph (better name) so it will not find the graph type ListGraph anymore.
The whole serialization system has been rewritten as well. It is now a lot more stable (no custom written hackish stuff) and is aimed to be both forwards and backwards compatible (well, not with the old system, but when updates to the new serialization system are made). It is based on Json and now you can actually save graph data, unzip it (yes it is stored as a zip) and edit the graph settings by hand!
Anyway, too many new features to list here (seriously!). Check out the changelog: http://arongranberg.com/astar/docs/changelog.php

Version 3.1 has been submitted to the Asset Store, but it might take a few days for it to be approved.
