Just tested my queries with M05. Now I get the result in 6.6sec instead of
10sec with M04. :) This is great! 30% improvement.
However, I might have found a regression. One of my earlier queries now
gives me a SystaxError Exception:
org.neo4j.cypher.SyntaxError: Don't know how to compare that. Left: 6;
Right: 8

The query in question was:
start c=(typeIndex,`node_type`,"1") match(c)-->(r) where (c.`node_name` =
"name") and (r.op_type = "8") return c,r
The "8" from the error message relates to the "8" in the where statement.
