When you carry hundreds of products and thousands of variants, every extra click and every scattered detail adds friction. This release tackles that directly: bulk ordering lets customers pick quantities across every variant in one step, bundles connect related products so shoppers do not have to hunt for them, and new product page blocks keep availability, timing, and safety information consistent across your whole range. ## Highlight Features ### Order Every Variant at Once with Bulk Ordering The bigger your catalog, the more variants each product tends to have, and the more likely shoppers are to buy several at once. Tech buyers often need more than one of something: several cable lengths, a mix of storage sizes, or a handful of chargers in different colors. Adding each variant one by one is slow and easy to get wrong. The new Quick order list section puts every variant in a single table on the product page, so shoppers set all their quantities at once and add everything to the cart in one step. Live line totals and a running subtotal keep the math visible as they go, so there are no surprises at checkout. **Also on product pages:** Quick buy now supports the same bulk order table directly from the listing. Each section can use either the standard variant picker or the bulk order table, so you can switch on bulk buying where it makes sense (accessories, consumables, spare parts) and keep the classic picker elsewhere. For large catalogs, that means shoppers can build a multi-variant order right from a collection page without opening product after product.

A camera needs a memory card, a laptop needs a sleeve, a console needs a second controller. In a large catalog, the right accessory can be buried pages deep. The new Product bundle section lets you group related products and sell them together, so shoppers see what works with what and can pick up the full setup in one place instead of searching across your range. It is a natural way to raise average order value while saving customers the guesswork of finding compatible accessories.

Shoppers can now request a notification when a sold out variant is restocked, so you keep that demand instead of losing it to a competitor.

It is ideal for pre-order windows, flash deals on last generation models, or the release of a new device.

It includes built-in types for California Proposition 65 warnings and choking hazard notices, plus custom types for other product-specific notices. Electro now renders these disclosures on the product page and in the cart or cart drawer, so important safety information stays in front of shoppers right up to purchase. Because disclosures are structured data rather than copy pasted text, they are far easier to manage consistently across a large range of products. * **Four new Custom section blocks.** Build richer custom sections with new Product card, Collection card, Blog post card, and Contact form blocks. Feature a flagship product next to a buying guide, point to a category from a landing section, or add a contact form for pre-sale technical questions without extra apps. These cards make it easier to surface the right products and categories on landing pages when your range is too big to browse by menu alone. ## Bug Fixes & Under-the-hood * Fixed the Quick buy variant picker so it correctly reflects unavailable option combinations. * Fixed a vertical scroll issue in carousels. * Icon only header search now opens inside the header with quick results below it, instead of as an overlay at the top of the page, and no longer covers the search field when header settings change in the theme editor. * Product comparison on mobile now shares the row evenly when only two products are compared, instead of sizing them for a scrollable carousel.
