In WooCommerce 4.4.0, we introduced functionality that was intended to improve the handling of variable products with the “filter by attribute” widget. (#26260) This pull request caused some additional issues with the handling of attributes that weren’t used with variations, and the count was still incorrect for products that were marked “hidden for catalog”. We’ve decided to roll back the changes to the “filter by attribute” widget and reintroduce them in a future version of WooCommerce. (#27625)
We’ve also fixed an issue introduced in 4.5.0 which prevented “0” from being used as an attribute value for variations. (#27633)
Here is the additional changelog for this release:
* Fix - Revert the changes in filtering by attribute that were introduced in WooCommerce 4.4. #27625 * Fix - Adjusted validation to allow for variations with "0" as an attribute value. #27633
Thanks to everyone for reporting these issues promptly and helping out with the fix release.
