+Store and World configs have been rebuilt with strong types. The shape of these configs have also changed slightly for clarity, the biggest change of which is merging of `keySchema` and `valueSchema` into a single `schema` with a separate `key` for a table's primary key.
+
+To migrate, first update the imported config method:
+
+```diff filename="mud.config.ts"
+-import { mudConfig } from "@latticexyz/world/register";
++import { defineWorld } from "@latticexyz/world";
+
+-export default mudConfig({
++export default defineWorld({
+```
+
+_Note that if you are only using Store, you will need to import `defineStore` from `@latticexyz/store`._
+
+Then migrate the table key by renaming `keySchema` to `schema` and define the table `key` with each field name from your key schema:
+
+```diff filename="mud.config.ts"
+ export default defineWorld({
+   tables: {
+     Position: {
+-      keySchema: {
++      schema: {
+         player: "address",
+       },
+       valueSchema: {
+         x: "int32",
+         y: "int32",
+       },
++      key: ['player'],
+     },
+   },
+ });
+```
+
+Now we can merge the `valueSchema` into `schema`.
+
+```diff filename="mud.config.ts"
+ export default defineWorld({
+   tables: {
+     Position: {
+       schema: {
+         player: "address",
+-      },
+-      valueSchema: {
+         x: "int32",
+         y: "int32",
+       },
+       key: ['player'],
+     },
+   },
+ });
+```
+
+If you previously used the table config shorthand without the full `keySchema` and `valueSchema`, some of the defaults have changed. Shorthands now use an `id: "bytes32"` field by default rather than `key: "bytes32"` and corresponding `key: ["id"]`. To keep previous behavior, you may have to manually define your `schema` with the previous `key` and `value` fields.
+
+```diff filename="mud.config.ts"
+ export default defineWorld({
+   tables: {
+-    OwnedBy: "address",
++    OwnedBy: {
++      schema: {
++        key: "bytes32",
++        value: "address",
++      },
++      key: ["key"],
++    },
+   },
+ });
+```
+
+Singleton tables are defined similarly, where an empty `key` rather than `keySchema` is provided:
+
+```diff filename="mud.config.ts"
+-keySchema: {}
++key: []
+```
+
+Offchain tables are now defined as a table `type` instead an `offchainOnly` boolean:
+
+```diff filename="mud.config.ts"
+-offchainOnly: true
++type: 'offchainTable'
+```
+
+All codegen options have moved under `codegen`:
+
+```diff filename="mud.config.ts"
+ export default defineWorld({
+-  codegenDirectory: "…",
++  codegen: {
++    outputDirectory: "…",
++  },
+   tables: {
+     Position: {
+       schema: {
+         player: "address",
+         x: "int32",
+         y: "int32",
+       },
+       key: ['player'],
+-      directory: "…",
+-      dataStruct: false,
++      codegen: {
++        outputDirectory: "…",
++        dataStruct: false,
++      },
+     },
+   },
+ });
+```
