+## 2.0.2
+### Fixes
+- Underlying uploader fixes issues with tokens not being sent properly for users seeing
+  `Error!: Error: Error uploading to https://codecov.io: Error: Error uploading to Codecov: Error: Not Found`
+- #440 fix: Validation ordering
+
+## 2.0.1
+### Fixes
+- #424 fix: Issue in building all deep dependencies
+
+## 2.0.0
+On February 1, 2022, the `v1` uploader will be full sunset and no longer function. This is due
+to the deprecation of the underlying bash uploader. This version uses the new [uploader](https://github.com/codecov/uploader).
+
+The `v2` Action downloads, verifies, and runs the Codecov binary.
+
+### Breaking Changes
+- Multiple fields have not been transferred from the bash uploader or have been deprecated. Notably
+many of the `functionalities` and `gcov_` arguments have been removed. Please check the documentation
+for the full list.
+
+### Features
+- `dry-run` argument allows Codecov flow without uploading reports to Codecov
+- (Enterprise only) `slug` allows specifying the repository slug manually
+- (Enterprise only) `url` allows changing the upload host
+

 ## What does this repo do?
 
-This repo is a GitHub Action, meaning it integrates with the GitHub Actions CI/CD pipeline. It's meant to take formatted reports with code coverage stats and upload them to codecov.io. Our Node action uses the Actions toolkit to make system calls that allow us to run Codecov's bash uploader inside of Node. Essentially what we're doing in this action is downloading Codecov's bash uploader script from codecov.io/bash, saving it as a file in the current directory, executing the file via `exec` calls, then removing the script from the current directory.

 ### Easily upload coverage reports to Codecov from GitHub Actions
 
 >The latest release of this Action adds support for tokenless uploads from GitHub Actions!
 
+## ⚠️  Deprecation of v1
+**As of February 1, 2022, v1 has been fully sunset and no longer functions**
+
+Due to the [deprecation](https://about.codecov.io/blog/introducing-codecovs-new-uploader/) of the underlying bash uploader,
+the Codecov GitHub Action has released `v2`/`v3` which will use the new [uploader](https://github.com/codecov/uploader). You can learn
+more about our deprecation plan and the new uploader on our [blog](https://about.codecov.io/blog/introducing-codecovs-new-uploader/).
+
+We will be restricting any updates to the `v1` Action to security updates and hotfixes.
+
+### Migration from `v1` to `v3`
+The `v3` uploader has a few breaking changes for users
+- Multiple fields have not been transferred from the bash uploader or have been deprecated. Notably
+many of the `functionalities` and `gcov_` arguments have been removed. Please check the documentation
+below for the full list.
+
 ## Usage
 
-To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number (`@v1` is recommended) as a `step` within your `workflow.yml` file.
+To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number (`@v3` is recommended) as a `step` within your `workflow.yml` file.
 
 If you have a *private repository*, this Action also requires you to [provide an upload token](https://docs.codecov.io/docs/frequently-asked-questions#section-where-is-the-repository-upload-token-found-) from [codecov.io](https://www.codecov.io) (tip: in order to avoid exposing your token, store it as a `secret`). Optionally, you can choose to include up to four additional inputs to customize the upload context. **For public repositories, no token is needed**
