ClosureTable 3.0
The new version introduces an injection of the Adjacency List pattern to the pure Closure Table. Adjacency list's features allows to simplify most of the database queries dramatically. In the new version, all the existed bugs were fixed. I also introduced a method, that the community requested long ago. It is called createFromArray and is used to create a bunch of records by just passing an array of attributes to it.
However, the feature I mentioned is not the only thing I added while developing the 3.0. Explore the source!
