+
+## Breaking Changes
+
+### Change in Cart-Completion Strategy Response
+
+In previous versions, if you attempt to complete a cart that's already completed, you will receive a response with status code`409`, indicating a conflict.
+
+In v1.19 of the Medusa backend, the order or swap associated with the completed cart is returned instead with status code 200:
+
+```
+// completing a regular cart
+{
+  response_code: 200,
+  response_body: { data: order, type: "order" },
+}
+
+// completing a swap cart
+{
+  response_code: 200,
+  response_body: { data: swap, type: "swap" },
+}
+```
+
+### Replaced node-redis with ioredis
+
+In previous versions, the Medusa backend used `node-redis` to manage the Express session store.
+
+In v1.19, `node-redis` is replaced with `ioredis` for higher configurability of the Redis client used for session management, and to make Redis configurations consistent with Redis modules (such as the Redis Event or Cache modules) which use `ioredis`.

+
+## How to Update
+
+Run the following command in your project:
+
+```bash npm2yarn
+npm install @medusajs/medusa@1.19
+```
+
+To avoid unexpected issues with dependencies, it's also recommended to update all other Medusa plugins or packages you have installed.
