Version 0.5.0

This minor release completely overhauls the internals of Lumen by adding three new concepts:

  1. The Pipeline which encapsulates any data transformations and filtering applied to a table.
  2. Variable references which can be used to coordinate controls across a dashboard.
  3. SQLTransform components which allow pushing compute down to a SQL database.

Additionally this release adds support for validating a specification without actually evaluating it and serializing all Lumen components to a spec.

Version 0.3.0

This is the first "public" release of Lumen.

Version 0.1.0

This is the first public release of the Lumen project, which provides a framework to build dashboards from a simple yaml specification. It is designed to query information from any source, filter it in various ways and then provide views of that information, which can be anything from a simple indicator to a table or plot.

For now the Lumen project is available only from conda and can be installed with conda install -c pyviz/label/dev lumen.
