This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.
mainis currently in pre mode so this branch has prereleases rather than normal releases. If you want to exit prereleases, runchangeset pre exitonmain.Releases

#388
f053fb9Thanks @BramKaashoek! - Add support forExternalandExternalAmounttax modes on carts.New behavior
Externaltax mode —LineItem,CustomLineItem, and shipping methods can now carry anexternalTaxRate:createCarthonorsLineItemDraft.externalTaxRate,CustomLineItemDraft.externalTaxRate, andCartDraft.externalTaxRateForShippingMethod.addLineItem,addCustomLineItem, andsetShippingMethod/setCustomShippingMethodacceptexternalTaxRate.setLineItemTaxRate,setCustomLineItemTaxRate,setShippingMethodTaxRate.ExternalAmounttax mode — explicit gross amounts can be supplied per item and at the cart level:setLineItemTaxAmount,setCustomLineItemTaxAmount,setShippingMethodTaxAmount,setCartTotalTax.taxedPriceis whateversetCartTotalTaxlast set; it is no longer aggregated from line items.taxedShippingPricecontinues to mirrorshippingInfo.taxedPrice.cart.taxRoundingMode(HalfEven/HalfUp/HalfDown) instead of always usingMath.round.Cart total recomputation after update actions
CartUpdateHandler.applynow recomputescart.taxedPriceandcart.taxedShippingPriceafter every update batch (except inExternalAmountmode, where the cart total is authoritative viasetCartTotalTax).This fixes a pre-existing latent bug: previously these fields were only computed once during
create()and were never refreshed after update actions, so e.g. runningsetShippingMethodafter cart creation would leave the cart-level aggregate stale. It didn't show up before becauseLineItem.taxedPricewas never populated in any mode, so the aggregate had no contributors that could drift. With the new tax-mode work, line items and custom line items now actually carrytaxedPrice, which made the gap observable and required fixing.
