TinkerPop 3.0.0.M8 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* `Traversal` is now `Serializable` and with 99% of queries no longer needing lambdas, Gremlin-Java works over the wire.
* Added `VertexProperty.Cardinality` with `list`, `set`, and `single`. No more `Vertex.singleProperty()` method.
* Added `RangeByIsCountStrategy` that adds a `RangeStep` in front of `.count().is(<predicate>, <value>)` to minimize the amount of fetched elements.
-* Added `CoalesceStep` / `.coalesce()` that emits the first traversal which emits at least one element.
+* Added `CoalesceStep` / `coalesce()` that emits the first traversal which emits at least one element.
* Added more syntactic sugar tricks to the Gremlin sugar plugin -- `&`, `|`, `select from`, `gt`, etc.
* `Traversal.Admin` is consistent internal to steps, traversals, strategies, etc. For the user, `Traversal` is all they see.
* `TraversalHolder` is now called `TraversalParent` with the child/parent terminology used throughout.
