The use of the stock management is planned to be completely optional and thus will be be activatable per product type and controlled by own stock management classes so that your developer will be provided with the flexibility they are used to.
You can get an overview of the scheduled features on the fundraising page.
As usual we will inform you about the further steps on all different channels.
Update July 30, 2014
The fundraising has been cancelled in favour of the Isotope eCommerce Circle!
