[NTG-context] floatcombination alignment has changed?

Hi, In recent versions of ConTeXt, floatcombinations are not placed centered by default anymore. Consider the following MWE in which two cows are placed side by side: \placefigure{}{ \startfloatcombination \placefigure{}{\externalfigure[cow.pdf]} \placefigure{}{\externalfigure[cow.pdf]} \stopfloatcombination} In version 2016.07.01_16.28, the combination is placed horizontally. In the latest version, the combination is flushed to the left. Is this change by intention? If yes, could please anybody tell me how to restore the previous behavior; changing the "location" does not help. Thank you for your effort. Cheers, Christoph
