# Events, atomic cart quantity updates and bulk tax editing

*Version 1.271 – released 2026-06-10*

## Events with per-ticket attendees

Each ticket now carries its own attendee, and a storefront-ready events API exposes events and their tickets to any front end. The event form takes a rich body, and the guest line shown to buyers is yours to label or switch off.

## Atomic cart quantity updates

The carts endpoint accepts a new `set` mode that writes an exact quantity instead of adding to whatever is already there. Retries and concurrent updates from a custom storefront can no longer double a line.

## Bulk tax editing for products

Select any number of products and apply a tax rate or a Stripe tax code in one action. Correcting tax treatment across a catalog no longer means opening products one at a time.
