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.
