Release Notes

This is the first release of its kind.
The intention is to make it easier to download the full database including all materials, light sources, and cameras.
They come in USD and MaterialX formats, and also as minified JSON files (with whitespace, line breaks, and indentation removed) so they can be integrated as presets in DCC applications in a lightweight manner.
Releasing this way also has the benefit of increased visibility when there are updates.
I'm planning to add this very same package to package managers such as PyPI as well.
