 - In Go, a type alias like `type Event = mvccpb.Event`, alone or inside a `type ( … )` group, is now indexed and links to the type it names, so impact on that type reaches the code that uses the alias. Before, aliases were missing: a use written through the alias's package, like `clientv3.Event` or prometheus's `storage.AOptions{…}`, linked to nothing, and one inside the package, like `&PrometheusVersion{}` in prometheus's `web` package, linked to whichever type of that name the project had, there a test helper's struct. A method called on a value of an alias's type now reaches the aliased type's method rather than a namesake's, and a generic alias like `type Items[T any] = List[T]` links to `List`, so `xs.Len()` on one reaches `List.Len` instead of nothing. Re-index Go projects after upgrading.
 - In Go, a struct that embeds another is no longer treated as overriding the methods it redeclares. gin's `Engine` embeds `RouterGroup` and has a `Use` of its own, but calling `Use` on a `RouterGroup` only ever runs `RouterGroup.Use`; before, `codegraph_explore`'s call path and impact went on from it into `Engine.Use` and the code only the engine runs. The same held for every struct or defined type embedded in another that redeclares one of its methods, like etcd's `Mutex` inside `lockerMutex`. A call through an interface still reaches each type that implements it, the embedding struct included. Re-index Go projects after upgrading.
 - In JavaScript and TypeScript, a subclass's `static` method no longer counts as overriding an instance method of the same name in its base class, or the reverse, since calling one never runs the other. In webpack, `codegraph_explore`'s call path and impact went on from `Module`'s `deserialize(context)` into the `static deserialize(context)` of `NormalModule` and other modules. A static method still overrides its base's static method and an instance method its base's instance method, and JavaScript class members are now marked static, as TypeScript ones already were. Re-index JavaScript and TypeScript projects after upgrading. Thanks @inth3shadows for the report and @yang0228 for the pull request. (#2761)
+- In TypeScript and JavaScript, a class in a `.tsx` or `.jsx` file now links its base class's and interfaces' methods to its overrides, as a class in a `.ts` or `.js` file already did. `codegraph_explore`'s call path, callers and impact now follow a call through the base into the override, like outline's `BaseEmail.send()` reaching each email's `render()`. This also works across file types, such as an interface in a `.ts` file implemented in a `.tsx` one. Before, these classes had no override links at all. Re-index projects with `.tsx` or `.jsx` files after upgrading.
 - In Java, Kotlin, C# and Scala, each overload of an interface or base-class method now links only to the overrides with the same parameters. Before, every overload linked to every method of that name in the implementing class, so `ExampleService.putTairValue(String)` also led to `putTairValue(List<String>, double)`, and `codegraph_explore`'s call path, callers and impact went into overloads that call never runs. Where a parameter is a type parameter, like `save(T entity)` implemented as `save(String entity)`, or the class is written in another language than its interface, the number of parameters decides; a method declared once on each side links as before. Re-index Java, Kotlin, C# and Scala projects after upgrading. Thanks @hxj1225 for the report and @danusha2345 for the pull request. (#2663)
 - In Kotlin, a call on what one of your functions returns, like `repository().pending(1)` or `val repo = repository(); repo.pending(1)` with a `private fun repository(): RealRepo` in a test class, now links to the method of the type that function declares, including one the type inherits or an extension on it. Before, the chained call went to whichever `pending` the name matched first, like a test double's in another package, and the local was guessed from its name, which reached the interface. The function is found in the calling class, a class it inherits from or one around it, or at the top level, and a nested type like `Request.Builder` is that type, not another class's `Builder`. When the declared type has no such method, the call now links to nothing rather than a method of the same name elsewhere; a type from outside your project is matched by name as before. Re-index Kotlin projects after upgrading. Thanks @mindcipherrr for the report. (#2805)
 - In JavaScript and TypeScript, a `super.run()` call now links to the method of the class's parent, or of the nearest ancestor that has it, like three.js's `super.copy(source)` reaching `Object3D.copy`, so `codegraph_explore`'s call path and impact follow an override into the method it builds on. Before, such a call inside a method of the same name was dropped, and elsewhere it went to whatever method had the name, often the class's own or a sibling class's in the same file. A call from a static method reaches the parent's static method, and a call to a parent from outside your project, like `HTMLElement`, `Set` or `Promise`, links nothing.
