Perform tap on x, y location in ruby and appium 1.6

When I call the following, x: x, y:y, count: 1).release.perform

I get the following error:

Error -. Support for gestures other than Tap is not yet implemented. Please contact an Appium dev

I need to tap on a location via global coords, how is this possible in 1.6?

move to 1.6.1-beta. it is fixed.

PS there is also:
((AppiumDriver) driver).tap(1, x, y, 200);
