+## Version 2.0.0-next.9
+
+### Major changes
+
+**[feat: replace Schema with FieldLayout for contract internals (#1336)](https://github.com/latticexyz/mud/commit/de151fec07b63a6022483c1ad133c556dd44992e)** (@latticexyz/cli, @latticexyz/protocol-parser, @latticexyz/store, @latticexyz/world)
+
+- Add `FieldLayout`, which is a `bytes32` user-type similar to `Schema`.
+
+  Both `FieldLayout` and `Schema` have the same kind of data in the first 4 bytes.
+
+  - 2 bytes for total length of all static fields
+  - 1 byte for number of static size fields
+  - 1 byte for number of dynamic size fields
+
+  But whereas `Schema` has `SchemaType` enum in each of the other 28 bytes, `FieldLayout` has static byte lengths in each of the other 28 bytes.
+
+- Replace `Schema valueSchema` with `FieldLayout fieldLayout` in Store and World contracts.
+
+  `FieldLayout` is more gas-efficient because it already has lengths, and `Schema` has types which need to be converted to lengths.
+
+- Add `getFieldLayout` to `IStore` interface.
+
+  There is no `FieldLayout` for keys, only for values, because key byte lengths aren't usually relevant on-chain. You can still use `getKeySchema` if you need key types.
+
+- Add `fieldLayoutToHex` utility to `protocol-parser` package.
+
+- Add `constants.sol` for constants shared between `FieldLayout`, `Schema` and `PackedCounter`.
+
+**[feat(world,store): add initialize method, initialize core tables in core module (#1472)](https://github.com/latticexyz/mud/commit/c049c23f48b93ac7881fb1a5a8417831611d5cbf)** (@latticexyz/store)
+
+- `StoreCore`'s `initialize` function is split into `initialize` (to set the `StoreSwitch`'s `storeAddress`) and `registerCoreTables` (to register the `Tables` and `StoreHooks` tables).
+  The purpose of this is to give consumers more granular control over the setup flow.
+
+- The `StoreRead` contract no longer calls `StoreCore.initialize` in its constructor.
+  `StoreCore` consumers are expected to call `StoreCore.initialize` and `StoreCore.registerCoreTable` in their own setup logic.
+
+### Minor changes
+
+**[feat(world,store): add initialize method, initialize core tables in core module (#1472)](https://github.com/latticexyz/mud/commit/c049c23f48b93ac7881fb1a5a8417831611d5cbf)** (@latticexyz/cli, @latticexyz/world)
+
+- The `World` contract now has an `initialize` function, which can be called once by the creator of the World to install the core module.
+  This change allows the registration of all core tables to happen in the `CoreModule`, so no table metadata has to be included in the `World`'s bytecode.
+
+  ```solidity
+  interface IBaseWorld {
+    function initialize(IModule coreModule) public;
+  }
+  ```
+
+- The `World` contract now stores the original creator of the `World` in an immutable state variable.
+  It is used internally to only allow the original creator to initialize the `World` in a separate transaction.
+
+  ```solidity
+  interface IBaseWorld {
+    function creator() external view returns (address);
+  }
+  ```
+
+- The deploy script is updated to use the `World`'s `initialize` function to install the `CoreModule` instead of `registerRootModule` as before.

 # @latticexyz/protocol-parser
 
+## 2.0.0-next.9
+
+### Minor Changes
+
+- [#1336](https://github.com/latticexyz/mud/pull/1336) [`de151fec`](https://github.com/latticexyz/mud/commit/de151fec07b63a6022483c1ad133c556dd44992e) Thanks [@dk1a](https://github.com/dk1a)! - - Add `FieldLayout`, which is a `bytes32` user-type similar to `Schema`.
+
+  Both `FieldLayout` and `Schema` have the same kind of data in the first 4 bytes.
+
+  - 2 bytes for total length of all static fields
+  - 1 byte for number of static size fields
+  - 1 byte for number of dynamic size fields
+
+  But whereas `Schema` has `SchemaType` enum in each of the other 28 bytes, `FieldLayout` has static byte lengths in each of the other 28 bytes.
+
+  - Replace `Schema valueSchema` with `FieldLayout fieldLayout` in Store and World contracts.
+
+    `FieldLayout` is more gas-efficient because it already has lengths, and `Schema` has types which need to be converted to lengths.
+
+  - Add `getFieldLayout` to `IStore` interface.
+
+    There is no `FieldLayout` for keys, only for values, because key byte lengths aren't usually relevant on-chain. You can still use `getKeySchema` if you need key types.
+
+  - Add `fieldLayoutToHex` utility to `protocol-parser` package.
+
+  - Add `constants.sol` for constants shared between `FieldLayout`, `Schema` and `PackedCounter`.
+

+  The purpose of this is to give consumers more granular control over the setup flow.
+
+  - The `StoreRead` contract no longer calls `StoreCore.initialize` in its constructor.
+    `StoreCore` consumers are expected to call `StoreCore.initialize` and `StoreCore.registerCoreTable` in their own setup logic.

 # Change Log
 
+## 2.0.0-next.9
+
+### Major Changes
+
+- [#1336](https://github.com/latticexyz/mud/pull/1336) [`de151fec`](https://github.com/latticexyz/mud/commit/de151fec07b63a6022483c1ad133c556dd44992e) Thanks [@dk1a](https://github.com/dk1a)! - - Add `FieldLayout`, which is a `bytes32` user-type similar to `Schema`.
+
+  Both `FieldLayout` and `Schema` have the same kind of data in the first 4 bytes.
+
+  - 2 bytes for total length of all static fields
+  - 1 byte for number of static size fields
+  - 1 byte for number of dynamic size fields
+
+  But whereas `Schema` has `SchemaType` enum in each of the other 28 bytes, `FieldLayout` has static byte lengths in each of the other 28 bytes.
+
+  - Replace `Schema valueSchema` with `FieldLayout fieldLayout` in Store and World contracts.
+
+    `FieldLayout` is more gas-efficient because it already has lengths, and `Schema` has types which need to be converted to lengths.
+
+  - Add `getFieldLayout` to `IStore` interface.
+
+    There is no `FieldLayout` for keys, only for values, because key byte lengths aren't usually relevant on-chain. You can still use `getKeySchema` if you need key types.
+
+  - Add `fieldLayoutToHex` utility to `protocol-parser` package.
+
+  - Add `constants.sol` for constants shared between `FieldLayout`, `Schema` and `PackedCounter`.
+
+### Minor Changes
+
+- [#1472](https://github.com/latticexyz/mud/pull/1472) [`c049c23f`](https://github.com/latticexyz/mud/commit/c049c23f48b93ac7881fb1a5a8417831611d5cbf) Thanks [@alvrs](https://github.com/alvrs)! - - The `World` contract now has an `initialize` function, which can be called once by the creator of the World to install the core module.
+  This change allows the registration of all core tables to happen in the `CoreModule`, so no table metadata has to be included in the `World`'s bytecode.
+
+  ```solidity
+  interface IBaseWorld {
+    function initialize(IModule coreModule) public;
+  }
+  ```
+
+  - The `World` contract now stores the original creator of the `World` in an immutable state variable.
+    It is used internally to only allow the original creator to initialize the `World` in a separate transaction.
+
+    ```solidity
+    interface IBaseWorld {
+      function creator() external view returns (address);
+    }
+    ```
+
+  - The deploy script is updated to use the `World`'s `initialize` function to install the `CoreModule` instead of `registerRootModule` as before.
