 ## [Unreleased]
+
+## [3.0.0] - 2020-03-20
+
+### Added
+- Added `--verbose` arg to print stack traces in case of errors
+- Automatic git provider detection. If `--git-provider-url` contains "github" or "bitbucket" the `--git-provider` arg is not needed anymore. Until now, `bitbucket` was used as default if `--git-provider` was missing.
+- Improved error handling and log outputs
+
 ### Changed
+- Throw an error if a key is not found in the YAML file for `deploy` and `create-preview` commands. Until now, the missing key was silently added.
+- `--username` and `--pasword` are always required
+- Read `.gitops.config.yaml` from the master branch for `delete-preview`
 - The `--branch` arg of the `delete-preview` command now only refers to the app repo branch. The config repo changes are pushed to `master` by default or to a randomly created branch name if `--create_pr` is given.
 
 ### Removed
+- Arg shortcuts (except `-v` verbose and `-h` help)
+- The `requirements.txt` was removed in favor of requirements in `setup.py`. This allows installation with only `pip3 install .`
 - The `--branch` arg was removed for commands `deploy` and `create-preview`. For `create-preview` the app repo branch is detected via the `--pr_id`. All changes in the config repo are pushed to `master` by default, or to a randomly created branch name if `--create_pr` is given.
