This version is deprecated. Download the new version of ArangoDB

A maintenance release of ArangoDB 2.5 is available for download. The latest v2.5.2 comes with cluster speedups, some fixes in cluster mode and improved graph queries.

You can start an ArangoDB cluster on Digital Ocean with a single command, other cloud services will follow in the next days. Please try the new release, maybe on Digital Ocean with the new cluster setup script, and provide us your feedback.

Which cloud provider should we support next?

Here are the changes in the current maintenance release:

v2_5_2 (Release notes)

• modules stored in _modules are automatically flushed when changed
• added missing query-id parameter in documentation of HTTP DELETE /_api/query endpoint

• make graph viewer in web interface issue less expensive queries for determining a random vertex from the graph, and for determining vertex attributes
• issue #1285: syntax error, unexpected $undefined near ‘@_to RETURN obj this allows AQL bind parameter names to also start with underscores

• added Foxx.Repository#exists
• parallelise initialization of V8 context in multiple threads
