Project Jupyter develops open source software, standardizes protocols for interactive computing across dozens of programming languages, and defines open formats for communicating results with others.
Jupyter and the community has continued to grow in breadth and depth. There have been many new exciting developments from the community. For example, the Xeus C++ kernel framework is making many interesting kernels possible, complete with even widgets support, such as an interactive C++ kernel, and a new R kernel called Juniper.
From the community notebook frontends, nteract now runs in the web browser. Cocalc has a notebook frontend that supports real-time collaboration. BeakerX just released 1.0, with JVM and Spark support and polyglot programming and culminates their transition to being built on the Jupyter notebook and soon JupyterLab codebases.
We welcome all of these projects and many more from the community.
