### What
`__INTERNAL_CUSTOM_TURBOPACK_BINDINGS` behaves inconsistent across
exposed bindings interface. PR adjusts to apply it to all of the
interface, to allow to use this env to override any swc binaries. This
is not a public interface, no concern of breaking changes.
BREAKING CHANGE:
Using the built-in image optimization API, the URL is parsed with `new
URL()` constructor which automatically trims spaces.
However, the developer may choose a 3rd party image optimization API via
`loader` or `loaderFile` (or perhaps a deployment platform that has its
own built in loader), so we shouldn't assume the API will parse the URL
in the same way as
[WHATWG](https://url.spec.whatwg.org/#:~:text=If%20input%20contains%20any%20leading%20or%20trailing%20C0%20control%20or%20space%2C%20invalid%2DURL%2Dunit%20validation%20error.).
While we could trim on the client, its probably best to fail fast and
let the developer make a conscience decision if a trailing space should
be removed or remain (by explicitly using `%20`).
This resolves an issue where a prefetch react server components (RSC)
request incorrectly causes cache poisoning issues during revalidation
for applications configured with partial prerendering (PPR).
It removes the test which used the header directly, and instead defers
to the `handleRSCRequest` method which includes specific environment
implementations.
This also fixes a bug where the prefetch RSC request for the root page
was not normalized.
Bumped acorn to latest version to let it parse class properties.
Class properties and private properties support was landed in 8.6.0,
bumping acorn parser to latest version then we can parse all the
syntaxes.
## What?
A small update to FileSystemCache to replace sync calls with async.
## Why?
`loadTagsManifest` may be called multiple times per request. Since
`loadTagsManifest` is synchronous it blocks the main thread whilst
reading from the file system which could impact server performance.
Replacing these sync calls with async has no impact for consumers of the
FileSystemCache.

### What
Remove `swcMinify` related branches as the option is deprecated and it's
always enabled
* Remove the related branches for checking `config.swcMinify`
* Remove the related telemetry about `swcMinify`
### What
Remove `missingSuspenseWithCSRBailout` and always treate the conditions
where it was used as `true`.
### Why
This was an intended behavior introduced in 14.1, which requires users
to always add suspense boundaries if it's using any hook that could bail
out to client rendering. `missingSuspenseWithCSRBailout` as `true` was
the default behavior and you could disable it with
`missingSuspenseWithCSRBailout: false` in next config. Now after the
removal you will not be able to opt-out it.
When `alternates.canonical` is provided as a `URL` instance,
`searchParams` are discarded.
When canonical is provided as a string, the same search parameters work.
This behavior may be unintuitive.
#### Unexpected result (`foo=bar` is removed):
```ts
export const generateMetadata = () => {
const canonical = new URL(`https://example.com/test?foo=bar`);
return {
alternates: { canonical: canonical },
};
};
```
#### Works as expected:
```ts
export const generateMetadata = () => {
const canonical = new URL(`https://example.com/test?foo=bar`);
return {
alternates: { canonical: canonical.toString() },
};
};
```

### What?
Do not reuse `Compiler` instance.
### Why?
It exists only to support preserving comments from `print()` API for
modules created with `parse()` API, but it causes a problem for
`transform()` for very huge apps.
### How?
- Closes https://github.com/swc-project/swc/issues/8932
- Fixes#48960
- Fixes#65436
### What
Reland #57448 , add react-server condition resolving and apply
server-only rules to middleware
Closes NEXT-1653
Closes NEXT-3333
### Why
Middleware as the pre-routing layer that is indended to be light-weight.
Since it's on edge runtime and only run on server but not on client, it
doesn't need to include the client react bundles. Hence we apply
`react-server` export condition, that if users import React we can only
bundle server required APIs and if users use React client hooks we can
error.
### BREAKING CHANGE
This changes the behavior of the default image `loader` so that
[`Content-Disposition`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition#as_a_response_header_for_the_main_body)
header is now `attachment` for added protection since the API can serve
arbitrary remote images.
The new default value, `attachment`, forces the browser to download the
image when visiting directly. This is particularly important when
`dangerouslyAllowSVG` is true. Most users will not notice the change
since visiting pages won't behave any differently, only visiting images
directly.
Users can switch back to the old behavior by configuring `inline` in
next.config.js
```js
module.exports = {
images: {
contentDispositionType: 'inline',
},
}
## Why?
- Remove `favicon.ico` from empty templates
- Update Index pages in `default-empty` templates to be the same as the
`app-empty` templates
- x-ref: https://github.com/vercel/next.js/pull/65532
Updates the links to go to the respective dir version (app or pages) and
rely less on the current redirects.
Also, if app dir is default, should the folder for pages be called
"pages" instead?
# What
Remove the previous deprecated flags and warnings
Removed deprecated types:
In `next.config.js`
- `experimental.incrementalCacheHandlerPath` (has moved to new options
in next 14)
- `experimental.isrMemoryCacheSize` (has moved to new options in next
14)
- `outputFileTracing` (not support customization anymore)
- `swcMinify` (not support customization anymore)
In `next/types`
- `unstable_includeFiles` (already deprecated for a while)
- `unstable_excludeFiles` (already deprecated for a while)
Remove font loaders resolving for `@next/font`, users should directly
rely on `next/font`, they're intended to be removed.
Also removed the legacy tests
When a server action performs a redirect, we send an RSC request to the
redirect URL so that everything can be handled in a single roundtrip.
However, we forward the `next-action` header to that request. This means
that the intra-app RSC request will be incorrectly associated with an
action, and any rewrites we do for `next-action` requests (such as the
work in the Next.js builder to ensure actions are routed to streaming
outputs) won't be handled correctly.

## What
Ensures `nonce` is added to script and link tags Next.js renders.
Additional cases it now handles:
- We already passed `nonce` to the React rendering, though not
consistently on all cases where `renderToStream` is called, I'm
surprised there haven't been more reports of this, but now it will pass
it on all cases where React rendering is called that I could find
- In `get-layer-assets.tsx` we now pass `nonce` to both the `script` and
`link` tags
- When calling `ReactDOM.preload` the nonce was missing as well, ensured
that the nonce is included in that case as well.
Added a test that mimicks the reproduction by adding `next/font` in this
case.

Closes NEXT-
Fixes #

We've seen too many instances of folks accidentally committing their
`.env` files that I feel it's time to make this change.
Up until now, Next.js has recommended that you use `.env.local` when
working locally to store your environment variables. Some developers do
intentionally want to commit their `.env` file without secret values to
source control. However, the ecosystem is fragmented on `.local`
support.
There are tools which require secrets values that do _not_ support
`.local` and require using `.env`. This means that it's possible to dump
your secret values into a `.env` file and commit to source control,
thinking that the defaults would have you covered.
This change updates the defaults for `create-next-app` to ignore all
`.env` files by default. If you want to commit then, you opt-in by
modifying your `.gitignore`, versus the opposite.

### What
Remove the extra `__esModule` and `$$typeof` export for ESM client
module
For a client page reference, it changed on server side in renderer:
Previous: `{ __esModule, $$typeof, default }`
Now: `{ default }`
### Why
The Module object itself appears as a client reference but it can't be
rendered since it's not a real reference. I'm not sure why it was added
but I think the right thing for an ESM module is to not treat the module
itself as a client reference but only the objects inside of it. E.g. the
"default" export. That's what React does upstream for ESM modules.
Closes NEXT-3360
### What
Remove the auto appending `.xml` extension to the sitemap routes when
it's a dynamic route.
### Why
Previously we were adding `.xml` to `/[...paths/]sitemap` routes, but
the bad part is when you use it to generate multiple sitemaps with
`generateSitemaps` in format like `/[...paths/]sitemap.xml/[id]`, which
doesn't look good in url format and it can be inferred as xml with
content-type. Hence we don't need to add `.xml` in the url.
Before this change it could also result into the different url between
dev and prod:
dev: `/sitemap.xml/[id]`
prod: `/sitemap/[id].xml`
Now it's going to be aligned as `/sitemap/[id]`. Users can add extension
flexiblely.
