# Publish Template Design Changes

Apply template design changes to Apple Wallet passes that have already been distributed.

Use *Publish* to apply template design changes to Apple Wallet passes that
have already been distributed. Changes apply to:

* Images
* Logo text
* Colors
* Back of pass fields

> **Note:** With the exception of logo text, any changes made to fields on the *front of
> the pass* **will not** be applied to currently distributed passes.


> **Note:** While Publish is not supported for Google Wallet, Google Wallet passes will
> automatically update with any changes made to *class* fields. How it works:
> 
> * If a class value `class.*` is changed, all passes will be changed.
> * On [Update Pass](https://www.airship.com/docs/developer/rest-api/wallet/operations/passes/#updatepass), only that
>    pass is updated. Class values are not sent with the update object when
>    updating passes, so there is no effect on other passes.
> 
> Any field preceded by `class` constitutes a class field. For a full list of
> class fields, please visit the
> [Google Wallet documentation](https://developers.google.com/pay/save/guides/loyalty/design).

   calendar that appears after clicking the date field, or manually enter
   in YYYY-MM-DD format. Use the dropdown menus to make time selections.
