Making a release#

We should release early & often, following semver wherever possible.

Packages in this repository#

This repo has more than one package.

  1. The primary jupyter-server-proxy python package. This contains the actual proxying code, and the classic notebook extension. This is published on PyPI.

  2. The JupyterLab plugin, jupyterlab-server-proxy. This provides the launcher icons in JupyterLab. This is packaged into the Python package but also published to NPM for JupyterLab 2 compatibility.

  3. Various python packages in contrib/. These are convenience packages that help set up a particular application for use - such as Theia.

As of version 3.0.0, we keep the version numbers of the main Python package and the JupyterLab plugin in sync, but have no procedure for the Theia package yet. NPM package versioning is stricter than Python package versioning. For example if you want to release a release candidate the version should be in the form 3.0.0-rc.1, python will automatically treat this as 3.0.0rc1.
