Faunus & Titan 0.4.0 Released by Dan LaRocque.
Dan’s post:
Aurelius is pleased to announce the release of Titan and Faunus 0.4.0.
This is a new major release which changes Titan’s client API, internal architecture, and storage format, and as such should be considered non-stable for now.

The artifacts have propagated to Maven Central, though they have yet to appear in the search index on search.maven.org.
New Titan features:
* MultiQuery, which speeds up traversal queries by an order of magnitude for common branching factors
* Initial Fulgora release with the introduction of an in-memory storage backend for Titan based on Hazelcast
* A new Persistit backend (special thanks to Blake Eggleston)
* Completely refactored query optimization and execution framework which makes query answering faster – in particular for GraphQuery
* Metrics integration for monitoring
* additional GraphQuery primitives and support in ElasticSearch and Lucene
* refactoring and deeper testing of the standard locking implementation
* redesigned type definition API
* much more
Titan 0.4.0 uses a new storage format which is incompatible with older versions of Titan. It also introduces backwards-incompatible API changes around type definition.
