-- Easier upload
-  - Specify a wildcard pattern
-  - Specify an individual file
-  - Specify a directory (previously you were limited to only this option)
-  - Multi path upload
-    - Use a combination of individual files, wildcards or directories
-    - Support for excluding certain files
-- Upload an artifact without providing a name
-- Fix for artifact uploads sometimes not working with containers
-- Proxy support out of the box
-- Port entire action to typescript from a runner plugin so it is easier to collaborate and accept contributions
+🚧 Under construction 🚧

-Each artifact behaves as a file share. Uploading to the same artifact multiple times in the same workflow can overwrite and append already uploaded files:

-              path: ${{ github.workspace }}
-```
-
-> **_Warning:_** Be careful when uploading to the same artifact via multiple jobs as artifacts may become corrupted. When uploading a file with an identical name and path in multiple jobs, uploads may fail with 503 errors due to conflicting uploads happening at the same time. Ensure uploads to identical locations to not interfere with each other.
-
-In the above example, four jobs will upload four different files to the same artifact but there will only be one file available when `my-artifact` is downloaded. Each job overwrites what was previously uploaded. To ensure that jobs don't overwrite existing artifacts, use a different name per job:
-
-```yaml
-          uses: actions/upload-artifact@v3
-          with:
-              name: my-artifact ${{ matrix.node-version }}
-              path: ${{ github.workspace }}

 There is a trashcan icon that can be used to delete the artifact. This icon will only appear for users who have write permissions to the repository.
 
-The size of the artifact is denoted in bytes. The displayed artifact size denotes the raw uploaded artifact size (the sum of all the individual files uploaded during the workflow run for the artifact), not the compressed size. When you click to download an artifact from the summary page, a compressed zip is created with all the contents of the artifact and the size of the zip that you download may differ significantly from the displayed size. Billing is based on the raw uploaded size and not the size of the zip.
-
-# Limitations
-
-### Zipped Artifact Downloads
-
-During a workflow run, files are uploaded and downloaded individually using the `upload-artifact` and `download-artifact` actions. However, when a workflow run finishes and an artifact is downloaded from either the UI or through the [download api](https://developer.github.com/v3/actions/artifacts/#download-an-artifact), a zip is dynamically created with all the file contents that were uploaded. There is currently no way to download artifacts after a workflow run finishes in a format other than a zip or to download artifact contents individually. One of the consequences of this limitation is that if a zip is uploaded during a workflow run and then downloaded from the UI, there will be a double zip created.
-
-### Permission Loss
-
-:exclamation: File permissions are not maintained during artifact upload :exclamation: For example, if you make a file executable using `chmod` and then upload that file, post-download the file is no longer guaranteed to be set as an executable.
-
-### Case Insensitive Uploads
-
-:exclamation: File uploads are case insensitive :exclamation: If you upload `A.txt` and `a.txt` with the same root path, only a single file will be saved and available during download.
-
-### Maintaining file permissions and case sensitive files
-
-If file permissions and case sensitivity are required, you can `tar` all of your files together before artifact upload. Post download, the `tar` file will maintain file permissions and case sensitivity:
-
-```yaml
-  - name: Tar files
-    run: tar -cvf my_files.tar /path/to/my/directory
-
-  - name: Upload Artifact
-    uses: actions/upload-artifact@v3
-    with:
-      name: my-artifact
-      path: my_files.tar
-```
-
-### Too many uploads resulting in 429 responses
-
-A very minute subset of users who upload a very very large amount of artifacts in a short period of time may see their uploads throttled or fail because of `Request was blocked due to exceeding usage of resource 'DBCPU' in namespace` or `Unable to copy file to server StatusCode=TooManyRequests`.
-
-To reduce the chance of this happening, you can reduce the number of HTTP calls made during artifact upload by zipping or archiving the contents of your artifact before an upload starts. As an example, imagine an artifact with 1000 files (each 10 Kb in size). Without any modification, there would be around 1000 HTTP calls made to upload the artifact. If you zip or archive the artifact beforehand, the number of HTTP calls can be dropped to single digit territory. Measures like this will significantly speed up your upload and prevent uploads from being throttled or in some cases fail.
