Packages must match the type of listing they are used for.
Packages are only applied to listings that are waiting for a package or being renewed.
Only published package products can be chosen on the submission forms.
Choosing a package keeps the existing author of the listing.
Package limits are enforced when several listings are submitted at the same time.
Renewals paid for with a package product are counted against the customer’s package.
Listing Packages screen: sorting is limited to the displayed columns.
Listing Packages screen: delete links are tied to the package they delete, and saving requires the manage_options capability.
Package names are escaped in the package templates and on the order confirmation page.
Orders that contain a deleted product no longer cause an error when their status changes.
Administrators can revoke the listing package of a refunded order from the order actions menu.
Refunding an order that has a listing package adds a private order note; the package is kept.
Template change: my-packages.php, package-selection.php and resume-package-selection.php now escape package names. Themes that override these templates should update their copies.
