- 2b4acc3: feat(blob): Add support for custom headers in client upload method
  
  This change adds the ability to pass custom headers to the upload method in the client, which will be forwarded to the server endpoint specified by handleUploadUrl. This is particularly useful for sending authorization headers and solves issues like #796 and #420.

Major Changes
- 00dfe23: Vercel Blob is now GA! To celebrate this we're releasing the 1.0.0 version of the Vercel Blob SDK which includes multiple changes and improvements.
  
  Changes:
  - addRandomSuffix is now false by default
  - Blobs are cached for one month, configurable and with a lower limit of 1 min. Which means you cannot configure the blob cache to be less than 1 minute.
  - Random suffixes are now also added to the pathname of blob responses and content-disposition header.
  - Overwriting blobs now requires to use allowOverwrite: true. Example:
```
await put('file.png', file, { access: 'public' });

await put('file.png', file, { access: 'public' }); // This will throw

put('file.png', file, { access: 'public', allowOverwrite: true }); // This will work
```
  How to upgrade:
  - If you're using random suffixes by default, then add addRandomSuffix: true to put and onBeforeGenerateToken options.
  - If you're overwriting blobs, then add allowOverwrite: true to put and onBeforeGenerateToken options.
  - If you're using a cache-control of less than one minute, we recommend using a Vercel Function instead of a Blob. As Vercel Blob is primarily designed for caching content for a longer time.
  - If you're displaying the pathname field of Blob responses in a UI, and using random suffixes, make sure you adpat the UI to show the longer pathname.

Major Changes
- fcdc55e: - BREAKING CHANGE Return values are now read-only to improve in-memory caching
  
  It used to be possible to change the returned value as shown in this example:
```
import { get } from '@vercel/edge-config';
const countries = await get('allowedCountryCodes');
countries.DE = true; // Will now cause TypeScript to error
```
  Moving forward, modifications like the above will cause a type error.
  
  If there is a need to modify the value, then the clone function can be used to clone the data and make it modifiable.
```
import { get, clone } from '@vercel/edge-config';

const myArray = await get('listOfAllowedIPs');
const myArrayClone = clone(myArray); // Clones the data to make it modifiable
myArrayClone.push('127.0.0.1'); // The `push` operation will work now
```
- BREAKING CHANGE SDK now throws underlying errors
  
  Previous versions of the @vercel/edge-config package would catch most errors thrown by native functions and throw a generic network error instead - even if the underlying issue wasn't a network error. The new version will throw the original errors.
  
  Note applications which rely on the @vercel/edge-config: Unexpected error and @vercel/edge-config: Network error errors must adapt to the new implementation by ensuring other types of errors are handled as well.
- The SDK now uses stale-while-revalidate semantics during development
  
  When @vercel/edge-config is used during development, with NODE_ENV being set to development, any read operation will fetch the entire Edge Config once and keep it in-memory to quickly resolve all other read operations for other keys, without waiting for the network. Subsequent reads will update the in-memory data in the background.
  
  This behaviour can be disabled by setting the environment variable EDGE_CONFIG_DISABLE_DEVELOPMENT_SWR to 1, or by using the disableDevelopmentCache option on the createClient function.

- d85bb76: feat(kv): Switch to default for fetch cache option
  
  BREAKING CHANGE: When using Next.js and vercel/kv, you may have kv requests and/or Next.js resources using kv being cached when you don't want them to.
  
  If that's the case, then opt-out of caching with https://nextjs.org/docs/app/api-reference/functions/unstable_noStore.
  
  On the contrary, if you want to enforce caching of resources you can use https://nextjs.org/docs/app/api-reference/functions/unstable_cache.

- 0c98feb: fix(blob): allow client uploads in web workers

- c3afec3: Add onUploadProgress feature to put/upload
  
  You can now track the upload progress in Node.js and all major browsers when using put/upload in multipart, non-multipart and client upload modes. Basically anywhere in our API you can upload a file, then you can follow the upload progress.
  
  Here's a basic usage example:
```
const blob = await put('big-file.pdf', file, {
  access: 'public',
  onUploadProgress(event) {
    console.log(event.loaded, event.total, event.percentage);
  }
});
```

261319e: # Add abortSignal

Adds abortSignal option to all methods. This allows users to cancel requests using an AbortController and passing its signal to the operation.

Here's how to use it:

const abortController = new AbortController();

vercelBlob
  .put('canceled.txt', 'test', {
    access: 'public',
    abortSignal: abortController.signal,
  })
  .then((blob) => {
    console.log('Blob created:', blob);
  });

setTimeout(function () {
  // Abort the upload
  abortController.abort();
}, 100);

Minor Changes
- 8e278f2: # feat(blob): add advanced multipart upload methods
  
  This exposes the three different multipart steps as functions of the SDK. Before this change every multipart upload was uncontrolled, meaning the full data was passed to the SDK and the SDK took care of chunking and uploading.
  
  Now it's possible to manually upload chunks and start and complete the multipart upload. All of the new functions can be used both on the server and the browser. There are two different API's that can be used.
  
  All parts uploaded must be at least 5MB in size, except for the last part. The last part can be smaller than 5MB. If you have a single part, it can be any size. All parts must be the same size, except for the last part.
  
  Individual methods
  
  Use createMultipartUpload, uploadPart and completeMultipartUpload to manage the upload.
```
const { key, uploadId } = await vercelBlob.createMultipartUpload(
  'big-file.txt',
  { access: 'public' },
);

const part1 = await vercelBlob.uploadPart(fullPath, 'first part', {
  access: 'public',
  key,
  uploadId,
  partNumber: 1,
});

const part2 = await vercelBlob.uploadPart(fullPath, 'second part', {
  access: 'public',
  key,
  uploadId,
  partNumber: 2,
});

const blob = await vercelBlob.completeMultipartUpload(
  fullPath,
  [part1, part2],
  {
    access: 'public',
    key,
    uploadId,
  },
);
```
  Multipart uploader
  
  For multipart methods, since some of the data remains consistent (uploadId, key), you can make use of the createMultipartUploader. This function stores certain data internally, making it possible to offer convinient put and complete functions.
```
const uploader = await vercelBlob.createMultipartUploader('big-file.txt', {
  access: 'public',
});

const part1 = await uploader.uploadPart(1, createReadStream(fullPath));

const part2 = await uploader.uploadPart(2, createReadStream(fullPath));

const blob = await uploader.complete([part1, part2]);
```

- 5d71dda: # feat(blob): add downloadUrl and getDownloadUrl
  
  Adds a new blob property called downloadUrl. This URL will have the content-disposition set to attachment meaning it will force browsers to start a download instead of showing a preview. This URL can be used to implement download links. In addition to this new field the sdk is also exposing a new util function called getDownloadUrl which can also be used to derive a download URL from a blob URL.

- 898c14a: feat(blob): Add multipart option to reliably upload medium and large files
  
  It turns out, uploading large files using Vercel Blob has been a struggle for users. Before this change, file uploads were limited to around 200MB for technical reasons. Before this change, even uploading a file of 100MB could fail for various reasons (network being one of them).
  
  To solve this for good, we're introducting a new option to put and upload calls: multipart: true. This new option will make sure your file is uploaded parts by parts to Vercel Blob, and when some parts are failing, we will retry them. This option is available for server and client uploads.
  
  Usage:
```
const blob = await put('file.png', file, {
  access: 'public',
  multipart: true, // `false` by default
});

// and:
const blob = await upload('file.png', file, {
  access: 'public',
  handleUploadUrl: '/api/upload',
  multipart: true,
});
```
  If your file is a Node.js stream or a ReadableStream then we will gradually read and upload it without blowing out your server or browser memory.
  
  More examples:
```
import { createReadStream } from 'node:fs';

const blob = await vercelBlob.put(
  'elon.mp4',
  // this works 👍, it will gradually read the file from the system and upload it
  createReadStream('/users/Elon/me.mp4'),
  { access: 'public', multipart: true },
);
```
```
const response = await fetch(
  'https://example-files.online-convert.com/video/mp4/example_big.mp4',
);

const blob = await vercelBlob.put(
  'example_big.mp4',
  // this works too 👍, it will gradually read the file from internet and upload it
  response.body,
  { access: 'public', multipart: true },
);
```
Patch Changes
- fd1781f: feat(blob): allow folder creation
  
  This allows the creation of empty folders in the blob store. Before this change the SDK would always require a body, which is prohibited by the API. Now the the SDK validates if the operation is a folder creation by checking if the pathname ends with a trailling slash.
```
const blob = await vercelBlob.put('folder/', {
  access: 'public',
  addRandomSuffix: false,
});
```
