How to make a release

jupyter-server-proxy is a package available on PyPI and conda-forge. These are instructions on how to make a release.

Pre-requisites

Create a PR updating labextension/yarn.lock and continue only when its merged.

This helps us avoid leaving known vulnerabilities are unfixed. To do this, delete the file and manually perform the the build dist step in the .github/workflows/publish.yaml workflow's build job as summarized below.
```
rm labextension/yarn.lock

pip install --upgrade pip build
pyproject-build
```
Create a PR updating docs/source/changelog.md with github-activity and continue only when its merged.

Checkout main and make sure it is up to date.

git checkout main
git fetch origin main
git reset --hard origin/main

Update the version, make commits, and push a git tag with tbump.
```
pip install tbump
tbump --dry-run ${VERSION}

# run
tbump ${VERSION}
```
Following this, the CI system will build and publish a release.
Reset the version back to dev, e.g. 4.0.1-0.dev after releasing 4.0.0.
```
tbump --no-tag ${NEXT_VERSION}-0.dev
```
Following the release to PyPI, an automated PR should arrive to conda-forge/jupyter-server-proxy-feedstock with instructions.
