What’s New (Changelog) in WooCommerce Square v5.5.0
= 5.5.0 - 2026-08-31 =
* Fix - Prevent product sync from getting stuck when a product set to sync with Square is deleted.
* Fix - Automatically detect and recover a background sync job stuck in processing, unblock the sync queue, show an admin notice prompting a re run, and prune old failed scheduler actions.
* Fix - Skip products that Square rejects during a sync instead of failing the whole sync, and report the name, SKU and reason for each skipped product.
* Fix - Stop Square inventory pulls from writing zero stock for items Square has no real count for, never change a product's stock management setting on a zero, and honor the per product Sync with Square setting on all automatic pulls.
* Fix - Allow "Manage stock" to be changed on a synced product when WooCommerce is the system of record, and keep it read-only when Square is.
* Fix - Square inventory sync errors no longer interrupt checkout or refunds for orders paid through other payment gateways.
* Fix - Reuse the Square catalog sync idempotency key on an unchanged retry and generate a new one when the request body changes, so a rate limited sync on stores with many categories recovers instead of getting stuck.
* Fix - Sync no longer fails when Square already holds an item option whose name differs only by case, or when a store has more than 100 item options.
* Fix - Reuse an existing Square item option that differs only by capitalization, so variations use Square's spelling of the value instead of creating a duplicate option.
* Dev - Bump WordPress "Tested up to" to 7.1.
* Dev - Bump WooCommerce "tested up to" version 11.1.
* Dev - Bump WooCommerce minimum supported version to 10.9.
* Dev - Update PHP_CodeSniffer to 3.13.6 and WooCommerce Sniffs to 1.0.1.
