Short answers based on the licence, for the version in the catalog.

Common pitfalls
- Ship LICENSE and any NOTICE file and mark files you changed when you redistribute.
- The patent grant ends for anyone who sues over patent infringement in the code.
- The licence covers the code, not the trademark. Don't use the project's name or logo in a way that suggests an official product.
- Open core: at least one product under this licence has parts under a different, commercial licence (often an ee/ or enterprise folder). Check that the features you need are not in that part.
