-## 0.1.0
+## 0.1.3
 
-* Initial release
+* Fixed where `with: body_path` was not being used in generated GitHub releases
+
+## 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

+
+* 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

+## 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 envrinment 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`
