Description
Starting from L4.2, support for PHP 5.3 has been dropped.
It's time for Baum to try to move to a trait-based implementation so that we can "mix-in" nested set functionality instead of inheritening, which will improve composability.
I'm thinking of leaving the 1.0.x branch as-is (with needed bug-fixes) with a tag like 1.0.x-stable
. Then start a 1.1 branch with the new implementation.
