Wave v0.14 is released. This is mainly a security, performance, and bugfix release. The release also includes experimental support for building and controlling Wave dashboards using the R programming language.


The Wave server now ships with a built-in utility to generate, use, and manage API keys conveniently. See Security.

The Wave server also provides additional control over how it handles external requests. See Configuration.

Additionally, starting v0.14, Python app servers now only process requests originating from the Wave server. The API key/secret pair for accessing the app server is automatically generated for each launch, and can be overridden using the new H2O_WAVE_APP_ACCESS_KEY_ID and H2O_WAVE_APP_ACCESS_KEY_SECRET for development and testing, if required. See Configuration.

Adding R language support also introduced major changes and simplification in the backend app and communication protocols, which should make it simpler to ship support for interactive R web apps in the near future.

All the work that has gone into this release sets the stage for adding support for many more languages, scripting and command-line control of content and visualizations displayed in Wave.
