+
+## 0.1.3
+

+
+## 0.1.2
+
+- Add support for merging draft releases [#16](https://github.com/softprops/action-gh-release/pull/16)
+
+GitHub's api doesn't explicitly have a way of fetching a draft release by tag name which caused draft releases to appear as separate releases when used in a build matrix.
+This is now fixed.
+
+- Add support for newline-delimited asset list [#18](https://github.com/softprops/action-gh-release/pull/18)
+
+GitHub actions inputs don't inherently support lists of things and one might like to append a list of files to include in a release. Previously this was possible using a comma-delimited list of asset path patterns to upload. You can now provide these as a newline delimieted list for better readability
+
+```yaml
+- name: Release
+  uses: softprops/action-gh-release@v1
+  if: startsWith(github.ref, 'refs/tags/')
+  with:
+    files: |
+      filea.txt
+      fileb.txt
+      filec.txt
+  env:
+    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+
+- Add support for prerelease annotated GitHub releases with the new input field `with.prerelease: true` [#19](https://github.com/softprops/action-gh-release/pull/19)
+
+---
+
+## 0.1.1
+
+- Add support for publishing releases on all supported virtual hosts
+
+You'll need to remove `docker://` prefix and use the `@v1` action tag
+
+---
+
+## 0.1.0
+
+- Initial release

+## bootstrapping
+
+This a [JavaScript](https://help.github.com/en/articles/about-actions#types-of-actions) action but uses [TypeScript](https://www.typescriptlang.org/docs/home.html) to generate that JavaScript.
+
+You can bootstrap your environment with a modern version of npm and by running `npm i` at the root of this repo.
+
+## testing
+
+Tests can be found under under `__tests__` directory and are runnable with the `npm t` command.
+
+## source code
+
+Source code can be found under the `src` directory. Running `npm run build` will generate the JavaScript that will run within GitHub workflows.
+
+## formatting
+
+A minimal attempt at keeping a consistent code style is can be applied by running `npm run fmt`.

+> **⚠️ Note for Windows:** Paths must use `/` as a separator, not `\`, as `\` is used to escape characters with special meaning in the pattern; for example, instead of specifying `D:\Foo.txt`, you must specify `D:/Foo.txt`. If you're using PowerShell, you can do this with `$Path = $Path -replace '\\','/'`

-Doug Tangren (softprops) 2019
+> **⚠️ Note:** This action was previously implemented as a Docker container, limiting its use to GitHub Actions Linux virtual environments only. With recent releases, we now support cross platform usage. You'll need to remove the `docker://` prefix in these versions
+
+### Permissions
+
+This Action requires the following permissions on the GitHub integration token:
+
+```yaml
+permissions:
+  contents: write
+```
+
+When used with `discussion_category_name`, additional permission is needed:
+
+```yaml
+permissions:
+  contents: write
+  discussions: write
+```
+
+[GitHub token permissions](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token) can be set for an individual job, workflow, or for Actions as a whole.
+
+Note that if you intend to run workflows on the release event (`on: { release: { types: [published] } }`), you need to use
+a personal access token for this action, as the [default `secrets.GITHUB_TOKEN` does not trigger another workflow](https://github.com/actions/create-release/issues/71).
