 Access widening provides a way to loosen the access limits of classes, methods or fields. This includes making them public, or making them extendable (subclassable).

+Access widening may be used instead of [[tutorial:mixin_accessors|accessor mixins]], and there are currently 2 cases where the functionality provided by mixin is not sufficient:
   * Needing to access a (package) private class, especially for the purpose of shadowing or accessing a field or method in a mixin.
   * Being able to override final methods or subclass final classes.
     * If you want to subclass a class with only (package) private constructors, wideners are a good choice.
-Access widening is a type of //class tweaking//, and is defined in the class tweaker file. In previous Fabric versions, the class tweaker was known as the "access widener" (as it had no other functionality).

 As with other types of class tweaking, in order for access widening changes to show up in the decompiled source, run the ''genSources'' gradle task and then reload the gradle project in your IDE.

 A specific file format is used to define the access changes included in your mod. To aid IDEs you should use the ''.classtweaker'' file extension.
-The file must start with the following header. ''namespace'' should usually always be set to the word ''named'', and not your project namespace. Loom will remap the class tweaker file for you into ''intermediary'' along with your mod. In unobfuscated versions (upcoming, 1.21.12+), the namespace will be ''official'', and the class tweaker will not be remapped.
