Way to query all distinct edges in AQL

Previously,I can use the following to get all unique edges from a vertex

FOR v,c
IN 1..3
ANY "EntityA/A"
EDGES
OPTIONS {uniqueEdges:global,bfs: true}
RETURN c

Since 3.3.5, there is undocumentated change in AQL traversal that uniqueEdges:global is no longer supported. Does this mean that there is no way to query distinct edges in AQL?

One solution is to use DISTINCT, but to my understanding, this is a filter function after the traversal has been done, thus, do not help with the performance.

As you noticed the option uniqueEdges:global is not supported in recent 3.2 and 3.3 versions and the support of it is not planned for next releases. For now using RETURN DISTINCT is a working approach.

This pull request removes the unsupported option from the documentation.
