The "theoretical max" stock availability figures have up until now only considered stock of component stock items if the product didn't include any beer components. 

For example, if a mixed-pack product had a number of different beers in it, plus a box, the stock of the box wasn't part of the "theoretical max" calculation. If a product only "contained" a stock item, for example, a branded glass that you bought in and sold on, these have always used the stock item's stock level for the product.

Following our recent changes to have more control over these components, we've now included these in the "theoretical max" stock calculation, if the "Used when product is assembled from existing stock" box is ticked.

This change shouldn't cause you any problems, but will in some cases reduce how much Breww thinks you can produce, but this is being reduced to a more accurate number. If you have any questions on this and your own data, please open a support ticket and we will be happy to help.

This change will be applied later today.
