OmegaConf 2.2 is a major release. The most significant area of improvement in
2.2 is support for more flexible type hints in structured configs. In addition,
OmegaConf now natively supports two new primitive types, bytes
and pathlib.Path
.

typing.Union
) (#144) - Support nested container type hints in structured configs, e.g. dict-of-dict and list-of-list (#427)

typing.Optional
) (#460) - Add support for
bytes
-typed values (#844) - Add support for
pathlib.Path
-typed values (#97) ListConfig
now implements slice assignment (#736)- Enable adding a
ListConfig
to alist
via theListConfig.__radd__
dunder method (#849) - Add
OmegaConf.missing_keys()
, a method that returns the missing keys in a config object (#720) - Add

${foo:a,}
) are deprecated in favor of explicit quoted strings (e.g.,${foo:a,""}

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 a 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 tripled (485 to 1571).
