ArangoDB 1.4.15

This version is deprecated. Download the new version of ArangoDB

We have released a maintenance release of ArangoDB 1.4. bugfix for AQL query optimiser the following type of query was too eagerly optimised, leading to errors in code-generation: LET a = (FOR i IN [] RETURN i) LET b = (FOR i IN [] RETURN i) RETURN 1

the problem occurred when both lists in the subqueries were empty. In this case invalid code was generated and the query couldn’t be executed. You can download it from https://test.arangodb.com/download or use your package manager.
