Currently there is no way to add multiple meta tags with the same name attribute to the head of a page. This PR modifies the Head component to allow multiple meta tags with the same name if they have unique keys.
This is important for integrating with certain services like Google Scholar and Swiftype.
Fixes#10183
This PR fixes a bug where we'd accidentally pass-through the user-provided `srcSet` if the image was lazy, just to then replace it when we hydrate.

Fixes#19041
This pull request adjusts our experimental scroll restoration behavior to use `sessionStorage` as opposed to `History#replaceState` to track scroll position.
In addition, **it eliminates a scroll event listener** and only captures when a `pushState` event happens (thereby leaving state that needs snapshotted).
These merely adjusts implementation detail, and is covered by existing tests:
```
test/integration/scroll-back-restoration/
```

Fixes#16690Fixes#17073Fixes#20486
This ensures we render the locale domain on the `href` when using `next/link` previously the provided `href` was stilling being rendered which differed from the resulting `href` that was navigated to.
Fixes: https://github.com/vercel/next.js/issues/20612
This pull request makes `Router#push` and `Router#replace` function identically to `<Link />`, i.e. reset scroll when the new render is complete.
Users can opt out of this new behavior via:
```tsx
const path = '/my-page'
router.push(path, path, { scroll: false })
```

Fixes#3249
This ensures we detect domain specific locales and redirect them client-side. Tests have been added in the `i18n` suite to ensure the domain redirect is applied correctly during a client-side navigation
Fixes: https://github.com/vercel/next.js/issues/19174
This refactors to instead of throwing a specific error when a SSG data route 404s, we return it through props and render the 404 outside of the error handling flow. No additional tests have been added as existing tests should cover this.
Closes: https://github.com/vercel/next.js/issues/19243
This moves the scroll reset behavior to happen synchronously with the DOM commit, instead of a few ticks after the render completes.
This is necessary for components that read scroll state on mount.

Fixes#6462
This ensures the default path used for the `next/image` component includes the `basePath` when configured. Additional tests have also been added to ensure the image component is working correctly with `basePath` configured.
Fixes: https://github.com/vercel/next.js/issues/19711
This fixes `next/image` to properly ignore inherited styles applied to the `img` tag by a parent element.
Image styling should **always** be done by a wrapper element—not to the image itself!

Fixes#19817Fixes#19964
This makes sure we don't generate the wrong locale source variant for the rewrite requiring a `/` on the end which won't ever be added causing the rewrite to never match. Additional tests have been added to ensure this specific rewrite is working correctly.
Fixes: https://github.com/vercel/next.js/issues/20508
This makes sure the query isn't dropped when doing a history navigation with i18n. Additional tests have been added to ensure this is working correctly as well.
Fixes: https://github.com/vercel/next.js/issues/20212
This ensures we show an error for string values for `revalidate` since we currently don't handle these and instead it results in `revalidate: false` being used. This also adds tests for our `revalidate` checks to ensure they are triggered correctly and not triggered for valid values.
x-ref: https://github.com/vercel/next.js/issues/20310
This makes sure redirects to the index route properly end with a trailing slash or don't based on the `trailingSlash` config to ensure an additional redirect doesn't need to take place un-necessarily.
Fixes: https://github.com/vercel/next.js/issues/19405
This ensures the pages-manifest only includes forward slashes and not backslashes when adding i18n page references, this also adds tests ensuring we don't regress on this in the i18n-support test suite.
Fixes: https://github.com/vercel/next.js/issues/20330
There's currently two bugs with the font optimization, but we'd really like to ship a stable version.
To unblock the stable release, we're **temporarily** reflagging this. It'll be unflagged on canary again!
This makes sure the `locale` doesn't cause the wrong `href` to be resolved, this also ensures route specificity is correct when loading dynamic routes in production mode.

Currently if sizes is not defined, Next.js is setting sizes as:
```
(max-width: 640px) 640px, (max-width: 750px) 750px, (max-width: 828px) 828px, (max-width: 1080px) 1080px, (max-width: 1200px) 1200px, (max-width: 1920px) 1920px, (max-width: 2048px) 2048px, 3840px'
```
This pull request will make sizes be `100vw` by default, which will allow us to download "smaller" images than what's currently happening.
In a demo app I have, the difference is between downloading 488KB vs 1.4MB (in images)
Adds an err.sh link to the production build missing message. Also clears up `valid` as `production`.
Also fixes an edge case where an unhelpful error would be thrown because we checked for `.next` instead of `.next/BUILD_ID`
Added the out directory location as the list line during export to make sure people know where the files are output.

## Why
Some users prefer to use a custom server implementation that handles body parsing. If they do this, they have no way to opt out of all body parsing in API Routes. Requests with bodies die if next's `bodyParser` is not disabled. Requests just hang forever.
Instead of adding [this config](https://nextjs.org/docs/api-routes/api-middlewares#custom-config) to every API Route, we do a simple check to avoid parsing the body twice.

## What
Restores handling of termination signals, `SIGTERM` and `SIGINT`, to allow graceful termination of next commands. Seems to have been removed during a child process refactor #6450, was this intentional?
## Why
Currently the command processes have to be forcefully killed. This would help those using Next.js with custom servers and tools like Docker and Kubernetes that rely on termination signals to shutdown instances.

Where would be a good location to add some tests? [test/integration/cli/test/index.test.js](fc98c13a2e/test/integration/cli/test/index.test.js)?
