+
+Rails `7.0` allows a more compact way to specify allowed values in a numericality validation.
+
+Instead of using combinations of `greater_than`, `greater_than_or_equal_to`, `less_than`, and `less_than_or_equal_to`, 
+you can use `in` with a range.
+
+**Before**
+
+```Ruby
+  validates :setting_reuse, numericality: { greater_than_or_equal_to: 0, less_than_or_equal_to: 12 }
+```
+
+**After**
+
+```Ruby
+  validates :setting_reuse, numericality: { in: 0..12 }
+```
+
+You get all the expressiveness that a range provides.
+Here are more examples each showing before and after:
+
+```Ruby
+  validates :setting_reuse, numericality: { greater_than_or_equal_to: 2 }
+  validates :setting_reuse, numericality: { in: 2... }
+```
+
+```Ruby
+  validates :setting_reuse, numericality: { less_than: 12 }
+  validates :setting_reuse, numericality: { in: ...12 }
+```
