This affects the tags state-tree and state-tree-pruning.
Vitalik Buterin refers in his blog to "State Tree Pruning".
Gavin Wood more recently talks about the "State Trie Pruning".
So, what is it, the the State-Trie or the State-Tree?
Since also Christian Reitwiessner in his most recent post also refers to state trie pruning, I would suggest to rename the tags using the term trie.
The wikipedia entry also explains why trie is the more correct term.
Update: Tag is now state-trie-pruning.
Tree is the more general term; trie is a more precise term technically since it's a more specific type of tree... Trie is more nitpicky. I think using the general term, "tree", is better for tagging purposes and is accurate enough.
