+# Changelog
+
+## [2.1.0] - 2020-08-10
+- Strip refs/heads/ from the input tag [#23](https://github.com/svenstaro/upload-release-action/pull/23) (thanks @OmarEmaraDev)
+
+## [2.0.0] - 2020-07-03
+- Add `prerelease` input parameter. Setting this marks the created release as a pre-release.
+- Add `release_name` input parameter. Setting this explicitly sets the title of the release.
+- Add `body` input parameter. Setting this sets the text content of the created release.
+- Add `browser_download_url` output variable. This contains the publicly accessible download URL of the uploaded artifact.
+- Allow for leaving `asset_name` unset. This will cause the asset to use the filename.

-- Do checkin source (src)
-- Do checkin build output (lib)
-- Do checkin runtime node_modules
-- Do not checkin devDependency node_modules (husky can help see below)
-
-### devDependencies
-
-In order to handle correctly checking in node_modules without devDependencies, we run [Husky](https://github.com/typicode/husky) before each commit.
-This step ensures that formatting and checkin rules are followed and that devDependencies are excluded. To make sure Husky runs correctly, please use the following workflow:
-
-```
-npm install                                 # installs all devDependencies including Husky
-git add abc.ext                             # Add the files you've changed. This should include files in src, lib, and node_modules (see above)
-git commit -m "Informative commit message"  # Commit. This will run Husky
-```
-
-During the commit step, Husky will take care of formatting all files with [Prettier](https://github.com/prettier/prettier) as well as pruning out devDependencies using `npm prune --production`.
-It will also make sure these changes are appropriately included in your commit (no further work is needed)
