A new feedstock type Gas has been introduced. On the Feedstocks tab, the Add Gas button has been added to the Feedstocks group of the Home ribbon tab. The Add Feedstocks button has been renamed Add Import.
Click the Add Gas button to add a new feedstock of type Gas to the grid. You can then edit values in the new row, just like with other feedstock types.

In the Gas Feedstock Composition tab you can add various gas components and then define their proportion in each of your gas feedstocks. Click Add Components to add one or more gas components from a list of fixed materials you have access to. The components you select are added as rows in the tab grid. You can then enter the proportions of the selected components into the columns for each gas feedstock.

Click Show Properties to show or hide the properties of each gas feedstock below the composition data. When you change the composition of a gas feedstock, its properties are updated in real time.
