cfg.select(key) deprecated in favor of OmegaConf.select(cfg, key)
OmegaConf 2.0 is a major release introducing substantial new features, and introducing some incompatible changes. The biggest new feature is Structured Configs, which extends OmegaConf into an schema validation system as well as a configuration system. With Structured Configs you can create OmegaConf objects from standard dataclasses or attr classes (or objects). OmegaConf will retain the type information from the source object/class and validate that config mutations are legal.
This is the biggest OmegaConf release ever, the number of unit tests more than trippled (485 to 1571).
