 ## 1.0.0 (2021-05-19)
 
+Vendure v1.0 is here! 🎉
+
+**Note** with this release, all deprecated APIs have been removed. If you were still using any, you'll have a very small amount of work to do in switching over to their replacements. Removed deprecated APIs:
+
+* TypeScript: `EventBus.sucscribe()`, use `EventBus.ofType()` instead.
+* TypeScript: `getEntityOrThrow()` helper. Use `TransactionalConnection.getEntityOrThrow()` instead.
+* TypeScript: `Injector.getConnection()`. Use `Injector.get(TransactionalConnection)` instead.  
+* TypeScript: `PriceCalculationStrategy`. Use `OrderItemPriceCalculationStrategy` instead.
+* TypeScript: `TaxCalculationStrategy`. Use `ProductVariantPriceCalculationStrategy` instead.
+* TypeScript: `VendureConfig.authOptions.sessionSecret`. Use `VendureConfig.cookieOptions.secret` instead.
+* GraphQL: `SearchResult` type - `productPreview` & `productVariantPreview` fields. Use `productAsset.preview`, `productVariantAsset.preview` instead. 
+* GraphQL: `Order.adjustments`. Use `Order.discounts` instead.
+* GraphQL: `OrderItem.unitPriceIncludesTax`. This is removed as redundant - `unitPrice` is always without tax.
+* GraphQL: `OrderLine.totalPrice`. Use `OrderLine.linePriceWithTax` instead.
+* GraphQL: `OrderLine.adjustments`. Use `OrderLine.discounts` instead.
+* GraphQL: `Product.priceIncludesTax`. This is removed as redundant - `price` is always without tax.
