2.0.0 is a major release that targets Neo4J 2.0. It is backwards

Cypher syntax changes.

Changes between Neocons 1.1.0 and 2.0.0
Transaction Support (Neo4J Server 2.0)
Neocons 2.0 gains support for transactions.
Higher Level API
A group of Cypher statements can be executed in a transaction that will be committed automatically upon success. Any error during the execution will trigger a rollback.

Lower Level API
Transactions are instantiated from a group of Cypher statements
that are passed as maps to
1 2 3 4 5
and roll a transaction back, respectively.
Macro for working with a transaction
If you want a more fine grained control of working in a transaction without manually
committing or checking for exceptions, you can use the
1 2 3 4 5 6 7 8
If there any errors while processing, the transaction is rolled back.
The first argument is the variable which holds the transaction
information. The second argument to the macro is
which commits the transaction there are no errors.
Constraints Support (Neo4J 2.0 Only)
