+# Release Notes November 2023 (2023-11-07)
+
+:::danger
+This release contains **breaking changes**
+:::
+
+## New Features
+
+### `@typespec/compiler` New Features
+
+- Add new `unixTimestamp32` scalar to standard library.
+- Emitter Framework: Add hook for handling circular references.
+- Emitter Framework: `TypeEmitter` now supports Tuples.
+- Emit error diagnostic if a model spreads itself within its declaration.
+- Stop showing empty code frame when diagnostic has no location.
+
+### `@typespec/json-schema` New Features
+
+- Add support for `TupleLiteral`.
+
+### `@typespec/openapi3` New Features
+
+- Support `@summary` on data types which emit the JSON Schema `title` property.
+
+### `@typespec/playground` New features
+
+- Add a format button to the playground command bar.
+- Add a notification to the standalone playground when the playground has been saved.
+- Add resizable panes for the editor and output.
+- Add ability to configure via `createBrowserHost` if library loading should use system `importmap` or the es-module-shim library with `importmap-shim`. This was added due to the lack of support for external source map in browsers.
+- [vite plugin] Provide the ability to configure bundling local libraries with the playground or manage the `importmap` yourself with `skipBundleLibraries` option.
+
+## Bug Fixes
+
+### `@typespec/compiler` Bug Fixes
+
+- Fix: `@doc` and jsdoc comments disappear from multi-segment or nested namespaces.
+- Fix: Using `@overload` could result in incorrect `unassignable` type errors.
+- Fix: Referencing a template in an alias might cause augment decorators to not be applied on types referenced in the aliased type.
+- Fix: Issues with removing keys from `RekeyableMap`.
+- Fix: Properties filtered with `@withVisibility` will have their visibility removed. This prevent visibility from being applied twice and rendering invalid models.
+
+### `@typespec/openapi3` Bug Fixes
+
+- Fix: Stops emitting an error when using `@body _: void` in operation parameters and treat it as no body.
+- Fix: Using shared routes would, in some cases, result in a `duplicate-header` error.
+
+## Breaking Changes
+
+### Typescript types breaking change
+
+The `package.json` files for all packages have been changed to use the standard `types` field instead of the legacy `typesVersions` field to specify types for subpath exports. This means that packages consuming TypeSpec must use the `moduleResolution` setting with `node16` or `nodenext` in their `tsconfig.json`.
+You might see the following error:
+
+```bash
+Cannot find module '@typespec/compiler/testing'. Did you mean to set the 'moduleResolution' option to 'nodenext'
+```
+
+This can be resolved by changing the following in `tsconfig.json`:
+
+```diff
+-"moduleResolution": "ESNext",
++"moduleResolution": "node16",
+```
+
+### Dropped Support for Node version 16
+
+- All typespec packages now specify node 18 as the minimum version. Consuming packages should no longer use node 16 and update the node specification in the `engines` section of their package.json file appropriately.
+
+### `@typespec/playground` Breaking Changes
+
+- Styles must be imported seperately with `import \"@typespec/playground/styles.css\";`.
+
+### `@typespec/versioning` Breaking Changes
+
+- Update targets for `@added`, `@removed`, `@renamedFrom`, `@madeOptional` and `@typeChangedFrom` to more clearly communicate where they can be used. Specs that applied these decorators to types that could not be versioned (like `namespace`) will now receive an error diagnostic.
