+Added `@latticexyz/stash` package, a TypeScript client state library optimized for the MUD Store data model.
+It uses the MUD store config to define local tables, which support writing, reading and subscribing to table updates.
+It comes with a query engine optimized for "ECS-style" queries (similar to `@latticexyz/recs`) but with native support for composite keys.
+
+You can find usage examples in the [`@latticexyz/stash` README.md](https://github.com/latticexyz/mud/blob/main/packages/stash/README.md).
+
+This package is experimental and will have breaking changes while we refine its APIs and implementation. All of its exports are temporarily under `@latticexyz/stash/internal` until we consider it stable.
