 1. In a new branch, create a new Lerna package:
 
 ```console
-$ npm run create-package new-package

This package can also be used by other actions to interact with artifacts. Any changes or updates to this package will propagate updates to these actions so it is important that major changes or updates get properly tested.
 
 Any issues or feature requests that are related to the artifact actions should be filled in the appropriate repo.
 
 A limited range of unit tests run as part of each PR when making changes to the artifact packages. For small contributions and fixes, they should be sufficient.
 
-If making large changes, there are a few scenarios that should be tested.
+If making large changes, there are a few scenarios that should be tested:
 
-- Uploading very large artifacts (large artifacts get compressed using gzip so compression/decompression must be tested)
-- Uploading artifacts with lots of small files (each file is uploaded with its own HTTP call, timeouts and non-success HTTP responses can be expected so they must be properly handled)
+- Uploading very large artifacts
+- Uploading artifacts with lots of small files
 - Uploading artifacts using a self-hosted runner (uploads and downloads behave differently due to extra latency)
 - Downloading a single artifact (large and small, if lots of small files are part of an artifact, timeouts and non-success HTTP responses can be expected)
 - Downloading all artifacts at once
 
 Large architectural changes can impact upload/download performance so it is important to separately run extra tests. We request that any large contributions/changes have extra detailed testing so we can verify performance and possible regressions.
 
-It is not possible to run end-to-end tests for artifacts as part of a PR in this repo because certain env variables such as `ACTIONS_RUNTIME_URL` are only available from the context of an action as opposed to a shell script. These env variables are needed in order to make the necessary API calls.
+Tests will run for every push/pull_request [via Actions](https://github.com/actions/toolkit/blob/main/.github/workflows/artifact-tests.yml).
 
 # Testing
 
-Any easy way to test changes is to fork the artifact actions and to use `npm link` to test your changes.
+## Package tests
 
-1. Fork the [upload-artifact](https://github.com/actions/upload-artifact) and [download-artifact](https://github.com/actions/download-artifact) repos
-2. Clone the forks locally
-3. With your local changes to the toolkit repo, type `npm link` after ensuring there are no errors when running `tsc`
-4. In the locally cloned fork, type `npm link @actions/artifact`
-4. Create a new release for your local fork using `tsc` and `npm run release` (this will create a new `dist/index.js` file using `@vercel/ncc`)
-5. Commit and push your local changes, you will then be able to test your changes with your forked action
+To run unit tests for the `@actions/artifact` package:
+
+1. Clone `actions/toolkit` locally
+2. Install dependencies: `npm bootstrap`
+3. Change working directory to `packages/artifact`
+4. Run jest tests: `npm run test`
+
+## Within upload-artifact or download-artifact actions
+
+Any easy way to test changes for the official upload/download actions is to fork them, compile changes and run them.
+
+1. For your local `actions/toolkit` changes:
+   1. Change directory to `packages/artifact`
+   2. Compile the changes: `npm run tsc`
+   3. Symlink your package change: `npm link`
+2. Fork and clone either [upload-artifact](https://github.com/actions/upload-artifact) and [download-artifact](https://github.com/actions/download-artifact)
+   1. In the locally cloned fork, link to your local toolkit changes: `npm link @actions/artifact`
+   2. Then, compile your changes with: `npm run release`. The local `dist/index.js` should be updated with your changes.
+   3. Commit and push to your fork, you can then test with a `uses:` in your workflow pointed at your fork.
+   4. The format for the above is `<username>/<repository-name>/@<ref>`, i.e. `me/myrepo/@HEAD`

-This package is currently undergoing a major overhaul in preparation for `v4` versions of `upload-artifact` and `download-artifact` (these Actions will use a new `2.0.0` version of `@actions/artifact` that will soon be released). The upcoming version of `@actions/artifact` will take advantage of a major re-architecture with entirely new APIs.
+## v2 - What's New
 
-The upcoming `2.0.0` package and `v4` artifact Actions aim to solve some of the major pain-points that have made artifact usage difficult up until now.
+> [!IMPORTANT]
+> @actions/artifact v2+, upload-artifact@v4+, and download-artifact@v4+ are not currently supported on GHES yet. The previous version of this package can be found at [this tag](https://github.com/actions/toolkit/tree/@actions/artifact@1.1.2/packages/artifact) and [on npm](https://www.npmjs.com/package/@actions/artifact/v/1.1.2).
+
+The release of `@actions/artifact@v2` (including `upload-artifact@v4` and `download-artifact@v4`) are major changes to the backend architecture of Artifacts. They have numerous performance and behavioral improvements.
+
+### Improvements
+
+1. All upload and download operations are much quicker, up to 80% faster download times and 96% faster upload times in worst case scenarios.
+2. Once uploaded, an Artifact ID is returned and Artifacts are immediately available in the UI and [REST API](https://docs.github.com/en/rest/actions/artifacts). Previously, you would have to wait for the run to be completed before an ID was available or any APIs could be utilized.
+3. Artifacts can now be downloaded and deleted from the UI _before_ the entire workflow run finishes.
+4. The contents of an Artifact are uploaded together into an _immutable_ archive. They cannot be altered by subsequent jobs. Both of these factors help reduce the possibility of accidentally corrupting Artifact files. (Digest/integrity hash coming soon in the API!)
+5. This library (and `actions/download-artifact`) now support downloading Artifacts from _other_ repositories and runs if a `GITHUB_TOKEN` with sufficient `actions:read` permissions are provided.
+
+### Breaking changes
+
+1. Firewall rules required for self-hosted runners.
+
+    If you are using self-hosted runners behind a firewall, you must have flows open to [Actions endpoints](https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners/about-self-hosted-runners#communication-between-self-hosted-runners-and-github). If you cannot use wildcard rules for your firewall, see the GitHub [meta endpoint](https://api.github.com/meta) for specific endpoints.
+
+    e.g.
+
+    ```bash
+    curl https://api.github.com/meta | jq .domains.actions
+    ```
+
+2. Uploading to the same named Artifact multiple times.
+
+    Due to how Artifacts are created in this new version, it is no longer possible to upload to the same named Artifact multiple times. You must either split the uploads into multiple Artifacts with different names, or only upload once.
+
+3. Limit of Artifacts for an individual job.
+
+    Each job in a workflow run now has a limit of 10 artifacts.
+
+## Quick Start
+
+Install the package:
+
+```bash
+npm i @actions/artifact
+```
+
+Import the module:
+
+```js
+// ES6 module
+import {DefaultArtifactClient} from '@actions/artifact'
+
+// CommonJS
+const {DefaultArtifactClient} = require('@actions/artifact')
+```
+
+Then instantiate:
+
+```js
+const artifact = new DefaultArtifactClient()
+```
+
+ℹ️ For a comprehensive list of classes, interfaces, functions and more, see the [generated documentation](./docs/generated/README.md).
+
+## Examples
+
+### Upload and Download
+
+The most basic scenario is uploading one or more files to an Artifact, then downloading that Artifact. Downloads are based on the Artifact ID, which can be obtained in the response of `uploadArtifact`, `getArtifact`, `listArtifacts` or via the [REST API](https://docs.github.com/en/rest/actions/artifacts).
+
+```js
+const {id, size} = await artifact.uploadArtifact(
+  // name of the artifact
+  'my-artifact',
+  // files to include (supports absolute and relative paths)
+  ['/absolute/path/file1.txt', './relative/file2.txt'],
+  {
+    // optional: how long to retain the artifact
+    // if unspecified, defaults to repository/org retention settings (the limit of this value)
+    retentionDays: 10
+  }
+)
+
+console.log(`Created artifact with id: ${id} (bytes: ${size}`)
+
+const {downloadPath} = await artifact.downloadArtifact(id, {
+  // optional: download destination path. otherwise defaults to $GITHUB_WORKSPACE
+  path: '/tmp/dst/path',
+})
+
+console.log(`Downloaded artifact ${id} to: ${downloadPath}`)
+```
+
+### Delete an Artifact
+
+To delete an artifact, all you need is the name.
+
+```js
+const {id} = await artifact.deleteArtifact(
+  // name of the artifact
+  'my-artifact'
+)
+
+console.log(`Deleted Artifact ID '${id}'`)
+```
+
+It also supports options to delete from other repos/runs given a github token with `actions:write` permissions on the target repository is supplied.
+
+```js
+const findBy = {
+  // must have actions:write permission on target repository
+  token: process.env['GITHUB_TOKEN'],
+  workflowRunId: 123,
+  repositoryOwner: 'actions',
+  repositoryName: 'toolkit'
+}
+
+
+const {id} = await artifact.deleteArtifact(
+  // name of the artifact
+  'my-artifact',
+  // options to find by other repo/owner
+  { findBy }
+)
+
+console.log(`Deleted Artifact ID '${id}' from ${findBy.repositoryOwner}/ ${findBy.repositoryName}`)
+```
+
+### Downloading from other workflow runs or repos
+
+It may be useful to download Artifacts from other workflow runs, or even other repositories. By default, the permissions are scoped so they can only download Artifacts within the current workflow run. To elevate permissions for this scenario, you must specify `options.findBy` to `downloadArtifact`.
+
+```ts
+const findBy = {
+  // must have actions:read permission on target repository
+  token: process.env['GITHUB_TOKEN'],
+  workflowRunId: 123,
+  repositoryOwner: 'actions',
+  repositoryName: 'toolkit'
+}
+
+await artifact.downloadArtifact(1337, {
+  findBy
+})
+
+// can also be used in other methods
+
+await artifact.getArtifact('my-artifact', {
+  findBy
+})
+
+await artifact.listArtifacts({
+  findBy
+})
+```
+
+### Speeding up large uploads
+
+If you have large files that need to be uploaded (or file types that don't compress well), you may benefit from changing the compression level of the Artifact archive. NOTE: This is a tradeoff between artifact upload time and stored data size.
+
+```ts
+await artifact.uploadArtifact('my-massive-artifact', ['big_file.bin'], {
+  // The level of compression for Zlib to be applied to the artifact archive.
+  // - 0: No compression
+  // - 1: Best speed
+  // - 6: Default compression (same as GNU Gzip)
+  // - 9: Best compression
+  compressionLevel: 0
+})
+```

+# Frequently Asked Questions
+
+- [Frequently Asked Questions](#frequently-asked-questions)
+  - [Supported Characters](#supported-characters)
+  - [Compression? ZIP? How is my artifact stored?](#compression-zip-how-is-my-artifact-stored)
+  - [Which versions of the artifacts packages are compatible?](#which-versions-of-the-artifacts-packages-are-compatible)
+  - [How long will my artifact be available?](#how-long-will-my-artifact-be-available)
+
+## Supported Characters
+
+When uploading an artifact, the inputted `name` parameter along with the files specified in `files` cannot contain any of the following characters. If they are present in `name` or `files`,  the Artifact will be rejected by the server and the upload will fail. These characters are not allowed due to limitations and restrictions with certain file systems such as NTFS. To maintain platform-agnostic behavior, characters that are not supported by an individual filesystem/platform will not be supported on all filesystems/platforms.
+
+- "
+- :
+- <
+- \>
+- |
+- \*
+- ?
+
+In addition to the aforementioned characters, the inputted `name` also cannot include the following
+- \
+- /
+
+## Compression? ZIP? How is my artifact stored?
+
+When creating an Artifact, the files are dynamically compressed and streamed into a ZIP archive. Since they are stored in a ZIP, they can be compressed by Zlib in varying levels.
+
+The value can range from 0 to 9:
+
+- 0: No compression
+- 1: Best speed
+- 6: Default compression (same as GNU Gzip)
+- 9: Best compression
+
+Higher levels will result in better compression, but will take longer to complete.
+For large files that are not easily compressed, a value of 0 is recommended for significantly faster uploads.
+
+## Which versions of the artifacts packages are compatible?
+[actions/upload-artifact](https://github.com/actions/upload-artifact) and [actions/download-artifact](https://github.com/actions/download-artifact), leverage [GitHub Actions toolkit](https://github.com/actions/toolkit) and are typically used together to upload and download artifacts in your workflows.
+
+| upload-artifact | download-artifact | toolkit |
+|---|---|---|
+| v4 | v4 | v2 |
+| < v3 | < v3 | < v1 |
+
+Use matching versions of `actions/upload-artifact` and `actions/download-artifact` to ensure compatibility.
+
+In your GitHub Actions workflow YAML file, you specify the version of the actions you want to use. For example:
+
+```yaml
+  uses: actions/upload-artifact@v4
+  # ...
+  uses: actions/download-artifact@v4
+  # ...
+```
+
+**Release Notes:**
+Check the release notes for each repository to see if there are any specific notes about compatibility or changes in behavior.
+
+## How long will my artifact be available?
+The default retention period is **90 days**. For more information, visit: https://github.com/actions/upload-artifact?tab=readme-ov-file#retention-period

+### compressionLevel
+
+• `Optional` **compressionLevel**: `number`
+
+The level of compression for Zlib to be applied to the artifact archive.
+The value can range from 0 to 9:
+- 0: No compression
+- 1: Best speed
+- 6: Default compression (same as GNU Gzip)
+- 9: Best compression
+Higher levels will result in better compression, but will take longer to complete.
+For large files that are not easily compressed, a value of 0 is recommended for significantly faster uploads.

+### retentionDays
+
+• `Optional` **retentionDays**: `number`
+
+Duration after which artifact will expire in days.
+
+By default artifact expires after 90 days:
+https://docs.github.com/en/actions/configuring-and-managing-workflows/persisting-workflow-data-using-artifacts#downloading-and-deleting-artifacts-after-a-workflow-run-is-complete
+
+Use this option to override the default expiry.
+
+Min value: 1
+Max value: 90 unless changed by repository setting
+
+If this is set to a greater value than the retention settings allowed, the retention on artifacts
+will be reduced to match the max value allowed on server, and the upload process will continue. An
+input of 0 assumes default retention setting.

+# `@actions/attest`
+
+Functions for generating signed attestations for workflow artifacts.
+
+Attestations bind some subject (a named artifact along with its digest) to a
+predicate (some assertion about that subject) using the [in-toto
+statement](https://github.com/in-toto/attestation/tree/main/spec/v1) format. A
+signature is generated for the attestation using a
+[Sigstore](https://www.sigstore.dev/)-issued signing certificate.
+
+Once the attestation has been created and signed, it will be uploaded to the GH
+attestations API and associated with the repository from which the workflow was
+initiated.
+
+See [Using artifact attestations to establish provenance for builds](https://docs.github.com/en/actions/security-guides/using-artifact-attestations-to-establish-provenance-for-builds)
+for more information on artifact attestations.
+
+## Usage
+
+### `attest`
+
+The `attest` function takes the supplied subject/predicate pair and generates a
+signed attestation.
+
+```js
+const { attest } = require('@actions/attest');
+const core = require('@actions/core');
+
+async function run() {
+    // In order to persist attestations to the repo, this should be a token with
+    // repository write permissions.
+    const ghToken = core.getInput('gh-token');
+
+    const attestation = await attest({
+        subjects: [{name: 'my-artifact-name', digest: { 'sha256': '36ab4667...'}}],
+        predicateType: 'https://in-toto.io/attestation/release',
+        predicate: { . . . },
+        token: ghToken
+    });
+
+    console.log(attestation);
+}
+
+run();
+```
+
+The `attest` function supports the following options:
+
+```typescript
+export type AttestOptions = {
+  // Deprecated. Use 'subjects' instead.
+  subjectName?: string
+  // Deprecated. Use 'subjects' instead.
+  subjectDigest?: Record<string, string>
+  // Collection of subjects to be attested
+  subjects?: Subject[]
+  // URI identifying the content type of the predicate being attested.
+  predicateType: string
+  // Predicate to be attested.
+  predicate: object
+  // GitHub token for writing attestations.
+  token: string
+  // Sigstore instance to use for signing. Must be one of "public-good" or
+  // "github".
+  sigstore?: 'public-good' | 'github'
+  // HTTP headers to include in request to attestations API.
+  headers?: {[header: string]: string | number | undefined}
+  // Whether to skip writing the attestation to the GH attestations API.
+  skipWrite?: boolean
+}
+
+export type Subject = {
+   // Name of the subject.
+  name: string
+   // Digests of the subject. Should be a map of digest algorithms to their hex-encoded values.
+  digest: Record<string, string>
+}
+```
+
+### `attestProvenance`
+
+The `attestProvenance` function accepts the name and digest of some artifact and
+generates a build provenance attestation over those values.
+
+The attestation is formed by first generating a [SLSA provenance
+predicate](https://slsa.dev/spec/v1.0/provenance) populated with
+[metadata](https://github.com/slsa-framework/github-actions-buildtypes/tree/main/workflow/v1)
+pulled from the GitHub Actions run.
+
+```js
+const { attestProvenance } = require('@actions/attest');
+const core = require('@actions/core');
+
+async function run() {
+    // In order to persist attestations to the repo, this should be a token with
+    // repository write permissions.
+    const ghToken = core.getInput('gh-token');
+
+    const attestation = await attestProvenance({
+        subjectName: 'my-artifact-name',
+        subjectDigest: { 'sha256': '36ab4667...'},
+        token: ghToken
+    });
+
+    console.log(attestation);
+}
+
+run();
+```
+
+The `attestProvenance` function supports the following options:
+
+```typescript
+export type AttestProvenanceOptions = {
+  // Deprecated. Use 'subjects' instead.
+  subjectName?: string
+  // Deprecated. Use 'subjects' instead.
+  subjectDigest?: Record<string, string>
+  // Collection of subjects to be attested
+  subjects?: Subject[]
+  // URI identifying the content type of the predicate being attested.
+  token: string
+  // Sigstore instance to use for signing. Must be one of "public-good" or
+  // "github".
+  sigstore?: 'public-good' | 'github'
+  // HTTP headers to include in request to attestations API.
+  headers?: {[header: string]: string | number | undefined}
+  // Whether to skip writing the attestation to the GH attestations API.
+  skipWrite?: boolean
+  // Issuer URL responsible for minting the OIDC token from which the
+  // provenance data is read. Defaults to
+  // 'https://token.actions.githubusercontent.com".
+  issuer?: string
+}
+```
+
+### `Attestation`
+
+The `Attestation` returned by `attest`/`attestProvenance` has the following
+fields:
+
+```typescript
+export type Attestation = {
+  /*
+   * JSON-serialized Sigstore bundle containing the provenance attestation,
+   * signature, signing certificate and witnessed timestamp.
+   */
+  bundle: SerializedBundle
+  /*
+   * PEM-encoded signing certificate used to sign the attestation.
+   */
+  certificate: string
+  /*
+   * ID of Rekor transparency log entry created for the attestation (if
+   * applicable).
+   */
+  tlogID?: string
+  /*
+   * ID of the persisted attestation (accessible via the GH API).
+   */
+  attestationID?: string
+}
+```
+
+For details about the Sigstore bundle format, see the [Bundle protobuf
+specification](https://github.com/sigstore/protobuf-specs/blob/main/protos/sigstore_bundle.proto).
+
+## Sigstore Instance
+
+When generating the signed attestation there are two different Sigstore
+instances which can be used to issue the signing certificate. By default,
+workflows initiated from public repositories will use the Sigstore public-good
+instance and persist the attestation signature to the public [Rekor transparency
+log](https://docs.sigstore.dev/logging/overview/). Workflows initiated from
+private/internal repositories will use the GitHub-internal Sigstore instance
+which uses a signed timestamp issued by GitHub's timestamp authority in place of
+the public transparency log.
+
+The default Sigstore instance selection can be overridden by passing an explicit
+value of either "public-good" or "github" for the `sigstore` option when calling
+either `attest` or `attestProvenance`.
+
+## Storage
+
+Attestations created by `attest`/`attestProvenance` will be uploaded to the GH
+attestations API and associated with the appropriate repository. Attestation
+storage is only supported for public repositories or repositories which belong
+to a GitHub Enterprise Cloud account.
+
+In order to generate attestations for private, non-Enterprise repositories, the
+`skipWrite` option should be set to `true`.

 Note that GitHub will remove any cache entries that have not been accessed in over 7 days. There is no limit on the number of caches you can store, but the total size of all caches in a repository is limited to 10 GB. If you exceed this limit, GitHub will save your cache but will begin evicting caches until the total size is less than 10 GB.
 
+## ⚠️ Important changes
+
+The cache backend service has been rewritten from the ground up for improved performance and reliability. The [@actions/cache](https://github.com/actions/toolkit/tree/main/packages/cache) package now integrates with the new cache service (v2) APIs.
+
+The new service will gradually roll out as of **February 1st, 2025**. The legacy service will also be sunset on the same date. Changes in this release are **fully backward compatible**.
+
+**All previous versions of this package will be deprecated**. We recommend upgrading to version `4.0.0` as soon as possible before **February 1st, 2025.**
+
+If you do not upgrade, all workflow runs using any of the deprecated [@actions/cache](https://github.com/actions/toolkit/tree/main/packages/cache) packages will fail.
+
+Upgrading to the recommended version should not break or require any changes to your workflows beyond updating your `package.json` to version `4.0.0`.
+
+Read more about the change & access the migration guide: [reference to the announcement](https://github.com/actions/toolkit/discussions/1890).

 ## Usage
 
 This package is used by the v2+ versions of our first party cache action. You can find an example implementation in the cache repo [here](https://github.com/actions/cache).

 A cache gets downloaded in multiple segments of fixed sizes (now `128MB` to fail-fast, previously `1GB` for a `32-bit` runner and `2GB` for a `64-bit` runner were used). Sometimes, a segment download gets stuck which causes the workflow job to be stuck forever and fail. Version `v3.0.4` of cache package introduces a segment download timeout. The segment download timeout will allow the segment download to get aborted and hence allow the job to proceed with a cache miss.
 
 Default value of this timeout is 10 minutes (starting `v3.2.1` and higher, previously 60 minutes in versions between `v.3.0.4` and `v3.2.0`, both included) and can be customized by specifying an [environment variable](https://docs.github.com/en/actions/learn-github-actions/environment-variables) named `SEGMENT_DOWNLOAD_TIMEOUT_MINS` with timeout value in minutes.
