TingoDB is an embedded JavaScript in-process filesystem or in-memory database upwards compatible with MongoDB at the v1.4 API level. Note starting from version 0.6.x there is new configuration paramater apiLevel. Default value is 140 (1.4) but we started some adoptions for 2.x specific behaviour. For instance findAndModify will behave difeently if to use apiLevel:200 (2.x). Any contributions with
