PR [#15745](https://github.com/fastapi/fastapi/pull/15745) by [@tiangolo](https://github.com/tiangolo).538539Unblocks ✨ SO MANY THINGS ✨540541Before this, `router.include_router(other_router)` would take each path operation from `other_router` and "clone" it, or recreate it from scratch.542543This would mean that in the end there was only one top level router, part of the app.544545The way it is structured here is that there are a few additional classes to handle intermediate metadata for router and route inclusion. That way the information of "router X includes Y and Y includes Z" is stored somewhere, without affecting (recreating / cloning) the final route.546547#### Non Objectives548549Dependencies for 404: previously I intended to support dependencies that would be executed even for 404, but that would conflict with the fact that a router could _not_ find a match, but the next router _did_ find a match. Executing dependencies in the router that did not find a match would not make sense, they could consume the request, body, etc. This original idea was discarded.550551#### Specific Breaking Changes552553Now `router.routes` is no longer a plain list of `APIRoute` objects, it can contain these intermediate objects that can contain additional routers, forming a tree.554555Any logic that depended on iterating on the `router.routes` directly would be affected, that logic cannot expect to be able to extract data from a plain list of routes, as it's no longer a plain list but a tree.556557Additionally, any logic that iterated on `router.routes` to modify them would now also see these new objects, and would not see all the routes in the app.558559`router.routes` should be considered an internal implementation detail, only passed around to the FastAPI functions that need it.560561#### Features562563* Adding routes (path operations) after a router is included now works, they are reflected as they are not copied.564* Including `subrouter` in `mainrouter` can be done before adding routes (path operations) to `subrouter`, because now the entire object is stored instead of copying the routes.565* As routes are not copied, in some cases that might save some memory.566567#### Alpha Features568569This is not documented yet, so it's not officially supported yet and could change in the future.570571But, as `APIRoute` and `APIRouter` instances are now preserved, they could be customized.572573`APIRouter` has two new methods, `.matches()` and `.handle()`, counterpart to the existing ones in `APIRoute`. With this a router could customize how it matches and handles requests. For example, it could match only requests that include some specific header, for example for handling versions in headers.574575Still, for now, consider this very experimental and potentially changing and breaking in the future.576577#### Future Features Enabled578579* Custom `APIRoute` subclasses (undocumented, but already works as described above)580* Custom `APIRouter` subclasses (undocumented, but already works as described above)581* Dependencies per router582* Exception handlers per router583* Middleware per router584* Other features planned585586### Docs587588* 📝 Update release notes.
