Mercantor

1.3.0

• BREAKING (Google): Migrated to Merchant API v1. Google sunset the v1beta endpoints on 2026-02-28, so every sync, diagnostics and connection call in 1.2.0 failed. Products are now uploaded as productInputs into a Merchant Center data source, which Mercantor creates automatically on first sync.
• NEW: Product deletions are now propagated to Merchant Center. Previously a delete job was queued but never executed a delete call, so removed products stayed in Google indefinitely.
• NEW: Variation edits trigger a sync. WooCommerce fires woocommerce_update_product_variation from a separate data store, which was not hooked, so price and stock changes on a single variation were never uploaded.
• NEW: Automatic retry with exponential backoff for rate limits and server errors, instead of marking the product as permanently failed.
• NEW: Sync and validation failures are written to the diagnostics inbox with their actual message, plus a last_error column on the items table.
• NEW: WooCommerce HPOS and Cart/Checkout Blocks compatibility is now declared, so the plugin no longer shows as incompatible.
• NEW: Admin notice when Google revokes access, instead of silently failing every sync.
• FIX: Fatal error in the scheduled diagnostics job — DiagnosticsManager was constructed with four arguments in the wrong order.
• FIX: Fatal error when importing Google issues — DiagnosticsManager called ErrorsDAO::insert() and ::delete_by_item_id(), neither of which existed.
• FIX: Multilingual extraction never ran. ProductExtractor::extract_single() was private, so the MultilingualProductExtractor override was silently ignored and localized titles, descriptions, permalinks and images were dropped. Affected TranslatePress most severely.
• FIX: Product feed was always empty — the query selected three columns that do not exist in the schema.
• FIX: XML feed lost every “g:” prefix because addChild() was called without a namespace URI, producing a feed Merchant Center cannot read.
• FIX: A “&” in the shop name produced an empty feed title and a PHP warning; channel values are now XML-escaped.
• FIX: Feed no longer reports the SKU as a GTIN. Identifiers come from GTINResolver, and identifier_exists is set when none is found.
• FIX: Feed now exports variations with their own price, stock and images instead of only the parent product.
• FIX: Concurrent Action Scheduler workers no longer refresh the OAuth token simultaneously; the refresh is locked and happens 120 seconds before expiry.
• FIX: Token encryption upgraded to authenticated AES-256-GCM with a format marker. Undecryptable values (for example after a salt rotation) now report “not connected” instead of sending a corrupted bearer token. Existing AES-256-CBC values are still readable.
• FIX: Encryption failure no longer falls back to storing the token in plain text.
• FIX: ItemsDAO::update_status() keyed on the numeric row id while every caller passed the item_id string, so status updates hit no row.
• FIX: ItemsDAO::upsert() reported failure on successful updates because insert_id is 0 on the ON DUPLICATE KEY UPDATE branch.
• FIX: SettingsManager::set() reported failure when the value was unchanged.
• FIX: Feed export token and OAuth state are compared with hash_equals(); the public feed endpoint is throttled.
• FIX: Diagnostics now paginates through the whole catalog instead of reading only the first page.
• FIX: Schema migrations run after a plugin update, not only on activation.
• FIX: JavaScript strings are translatable — wp_set_script_translations() was never called.
• IMPROVED: Action Scheduler tuning is opt-in and only raises the batch size. The previous filters changed concurrency and time limits globally for WooCommerce and every other plugin on the site.
• IMPROVED: Admin bundle uses createRoot from @wordpress/element rather than window.ReactDOM, which React 19 will no longer provide.
• IMPROVED: Tested up to WordPress 7.1 and WooCommerce 11.0; declares Requires Plugins: woocommerce.
• IMPROVED: Namespace casing unified; test suite and static analysis now run against the shipped source and pass.
