# Modifying Custom Fields after a Package Is Released

The following changes are allowed to custom fields in a package, after it’s released.

| Availability                        |
| ----------------------------------- |
| Available in: **Developer** Edition |

- The length of a text field can be increased or decreased.
- The number of digits to the left or right of the decimal point in a number field can be increased or decreased.
- A required field can be made non-required and vice versa. If a default value was required for a field, that restriction can be removed and vice versa.
