+Zip file for testing: [woocommerce-gutenberg-products-block.zip](https://github.com/woocommerce/woocommerce-gutenberg-products-block/files/6608747/woocommerce-gutenberg-products-block.zip)
+
+### Hide the Cart and Checkout blocks from the new block-based widget editor. ([4303](https://github.com/woocommerce/woocommerce-gutenberg-products-block/pull/4303))
+
+1. Using a classic theme (ie: Storefront) with Gutenberg enabled, go to Appearance > Widgets.
+2. Verify you can't add the Cart block or the Checkout block. (You will see a widget called Cart, that's the widget from WC core and is not related to this PR, so ignore it).
+3. Now go to Appearance > Customize > Widgets and open a widget area.
+4. Verify you can't add the Cart block or the Checkout block either.
+
+### Fix some missing translations from the Cart and Checkout blocks. ([4295](https://github.com/woocommerce/woocommerce-gutenberg-products-block/pull/4295))
+
+1. Create a checkout page with the blocks
+2. Change your site language to a fully localized language as es-Es. ([Translation status](https://translate.wordpress.org/locale/es/default/wp-plugins/woo-gutenberg-products-block/))
+3. Go to Updates, scroll down and click update translation.
+4. Navigate to the checkout page and see that the checkout fields are being translated correctly.
+
+### Fix the flickering of the Proceed to Checkout button on quantity update in the Cart Block. ([4293](https://github.com/woocommerce/woocommerce-gutenberg-products-block/pull/4293))
+
+1. Smoke test Cart block, make sure changing quantity works fine.
+2. Make sure removing items works fine.
+3. When changing an item quantity, make sure the button is disabled immediately as you change the quantity and is re-enabled once the server request finishes
+
+### Fix a bug in which Cart Widget didn't update when adding items from the All Products block. ([4291](https://github.com/woocommerce/woocommerce-gutenberg-products-block/pull/4291))
+
+1. Use a theme that supports the Cart widget, like Storefront
+2. Go to a page with the All Products block in the content.
+3. Click on the Add to Cart button for a product.
+4. View the Add to Cart widget and the total should be updated to reflect the change.
+
+### Fix a display issue when itemized taxes are enabled, but no products in the cart are taxable. ([4284](https://github.com/woocommerce/woocommerce-gutenberg-products-block/pull/4284))
+

+
+1. Go WooCommerce -> Settings -> Tax and set Display prices during basket and checkout to Excluding Tax.
+2. Set Display tax totals to Itemised
+3. Add an item to the cart with a zero-rated tax rate.
+4. Check there are no borders without anything in them, like the before screenshot above.
+
+### Fix an issue where an attempt to add an out-of-stock product to the cart was made when clicking the "Read more" button. ([4265](https://github.com/woocommerce/woocommerce-gutenberg-products-block/pull/4265))
+
+1. Go to 'WooCommerce > Settings > Products > Enable AJAX add to cart buttons on archives
+2. Edit a page and add a 'Products by Category' block (choose a category with an out of stock product)
+3. On the front-end, go to the page and click on the out of stock product's "Read more" link
+4. Verify you cannot see the spinner on the button and when redirected on the product page, the WooCommerce error message does not show.
