Product options are now part of AddOnBoss. Install it and your sets, fields and positions are exactly where you left them.
Giving a simple product choices like colour and size, without creating WooCommerce variations, is now AddOnBoss. So is pricing by measured size, custom fields on a product’s own page, and print positions.
BundleBoss stayed what it always was: the bundle builder.
Two different jobs had grown inside one plugin. Bundles are about selling several products together. Product options are about one product offering choices. Plenty of shops want one without the other, and paying for both to get either was the wrong deal.
They still work together. A bundle can contain a product carrying option sets, and the choices flow through as before.
If you used product options: install AddOnBoss. Your sets, fields and positions are read from where they already are. Nothing needs rebuilding and nothing was deleted.
If you only build bundles: nothing.
The full guides live on the BossMage docs site:
Options inside a bundle are still here, because that is a bundle behaviour. See bundle items and choice slots.
Per-item personalisation on bundle items is also still BundleBoss. See personalisation.
