v6.13.0

Changed

• Empty querystring parameters are now omitted

  In some cases ArangoDB would be unable to correctly handle querystring
  parameters without values. Any paremeters set to undefined will now
  no longer be added to the querystring.

  This does not affect parameters set to empty string values.

Added

• Added maxRuntime option to db.query method

Fixed

• Replaced linkedlist dependency with x3-linkedlist (#601)

  The linkedlist dependency had a memory leak and was no longer maintained.
  The replacement should fix this issue.
