Bumping version
Preparation
Install bump2version.
Pre-release
Choose which version number category to bump following semver specification.
Test bumping version
bump2version --dry-run --verbose $CATEGORYwhere $CATEGORY is the target version number category name, possible
values are patch/minor/major.
Bump version
bump2version --verbose $CATEGORYThis will set version to major.minor.patch-alpha.
Release
Test bumping version
bump2version --dry-run --verbose releaseBump version
bump2version --verbose releaseThis will set version to major.minor.patch.
