In the last days we prepared everything for the first technical preview of ArangoDB 2.6, testing new and improved functionality and adding some small last minute features like the AQL explain command in the Web UI. We are proud of the new release and can’t wait to give it in your hands. Stay tuned, follow @arangodb to get the news first

Meanwhile last week we published a 2.5.4 maintenance release and provide a short glimpse on added features like Foxx dependencies for more composable Foxx Apps and Improved System User Authentication.

Did you know?

MATCHES(document, examples, return-index)
Compare documents
Compares the document against each example document provided in the array examples.
Example::

MATCHES(
  { "test" : 1 }, [
    { "test" : 1, "foo" : "bar" },
    { "foo" : 1 },
    { "test : 1 }
  ], true)

This will return 2, because the third example matches and because the return-index flag is set to true.
