Summary:
Prior to version 1.17.30, the number of available crafts was shown in the recipe book next to items, and after 1.17.30, the number of items received is shown.
For example when having enough resources to use the fence crafting recipe in the inventory (4 planks and 2 sticks) once it shows 3, since you get 3 fences. In older versions it showed 1, since that is the amount, how often you can use the crafting recipe.
This change was unannounced in any changelog afaik, so it could be unintentional. This is a problem, since it allows it to reach the limit of, which number it shows more easily (it shows 99+, when it is more than 99), meaning it shows less information and is less useful.

Steps to reproduce:

1. Take crafting materials where you get more than 1 item.
2. Open the recipe book in the crafting table.

Observed results:
Next to the item is the number of items you receive after crafting.

Expected results:
As before version 1.17.30, the number of crafts you can make will be indicated next to the item.
