### Bumping version
#### Preparation
Install
[bump2version](https://github.com/c4urself/bump2version#installation).
#### Pre-release
Choose which version number category to bump following [semver
specification](http://semver.org/).
Test bumping version
```bash
bump2version --dry-run --verbose $CATEGORY
```
where `$CATEGORY` is the target version number category name, possible
values are `patch`/`minor`/`major`.
Bump version
```bash
bump2version --verbose $CATEGORY
```
This will set version to `major.minor.patch-alpha`.
