+## [2.0.0] - 2019-12-28
+This is a major release as most of the code was refactored and some behavior was changed, for example "Tag version is set as a release title".
+
+### Fixed
+- Artifact files not found caused panic - all files now being validated before release creation
+- Custom changelog file now being validated before release creation
+- Arguments parsing fixed
+
+### Added
+- Unit testing
+- Docker image now built from scratch, resulting in decreased size 139.73MB -> 2.43MB, improving action overall speed.
+- **app** package
+- `ALLOW_EMPTY_CHANGELOG` env.var to allow publishing a release without changelog (default **false**)
+- Artifacts (provided as arguments) can now be separated by one of: `new line '\n', pipe '|', space ' ', comma ','`
+
+### Changed
+- **local** package renamed to **repository**
+- **remote** package splitted into 2 packages: **asset**, **release**
+- Tag version is set as a release title
