Alpha 2.6 is now released with new fixes and new features:

1. EZ page links are built correctly now
2. Allowing you to set the category depth level as far as you want.
Example: assuming you a category tree like this: 10_11_13_15
You can set it so that the names of the 3 last categories appear on the link:
c-category11name-category13name-category15name-10_11_13_15

For upgrader: there is a database patch in this new update, make sure you read the doc first.
