Features

• Support python3.11 (#1023)

2.2.3 (2022-08-18)

Bug Fixes

• Revert an accidental behavior change where implicit conversion from Path to str was disallowed. (#934)
• ListConfig sliced assignment now avoids partial updates upon error (#950)
• Fix a bug that caused OmegaConf to crash when processing attr classes whose field annotations contained forward-references. (#963)
• Improve error message when certain illegal type annotations (such as typing.Sequence) are used in structured configs. (#991)
• When parsing yaml: Disallow numbers with trailing underscore from being converted to float. (#838)

API changes and deprecations

Bug Fixes

2.2.1 (2022-05-17)

Features

• Support unions of primitive types in structured config type hints (typing.Union) (#144)
• Support nested container type hints in structured configs, e.g. dict-of-dict and list-of-list (#427)
• Improve support for optional element types in structured config container type hints (typing.Optional) (#460)
