How to cut a new release

Make certain your branch is in sync with head and then create a new release branch:
```
 git pull origin main
 git switch -c version_0.2.0
```
Update version to, e.g. 0.2.0 in package.json
Make sure that proptypes in fragments/Vega.react.js and components/Vega.react.js are in sync
Build new version and test it npm install npm run build
```
 python example_app.py
```

Commit changes and push:

 git add . -u
 git commit -m "MAINT: Bump version to 0.2.0"
 git push

Merge release branch into main, make sure that all required checks pass

On main, build source & wheel distributions:

 git checkout main
 git pull

 rm -rf dist
 python setup.py sdist bdist_wheel

Publish to PyPI (Requires correct PyPI owner permissions):
```
 twine upload dist/*
```

On main, tag the release:

 git tag -a v0.2.0 -m "Version 0.2.0 release"
 git push origin v0.2.0

Add release in https://github.com/binste/dash-vega-components/releases and select the version tag

Update version to e.g. 0.3.0dev in package.json in new branch

git switch -c maint_0.3.0dev
# Change version, then:
npm install
npm run build

Commit change and push:

git add . -u
git commit -m "MAINT: Bump version to 0.3.0dev"
git push

Merge maintenance branch into main
