Sourced from mypy-protobuf's changelog.

5.0.0

• Use builtins.property to handle conflicts with fields named property
• Mangle all non provided message type imports, this prevents conflicts with field names like collections, builtins, etc.
  • Do not mangle message imports, as that would be a breaking change.
• BREAKING: Refactor import statements
  • Move to model similar to protoc pyi generator. This prevents name collisions in field names
    • from test.a.b import c as _c
    • If multiple names collied, append _{count}
      • from test.a.x import c as _c_1
  • Fix bug in duplicate package name imports
• Export stub methods as properties instead of attributes if deprecated and mark as such
• Export enum fields as properties on class level (not module level) enums if deprecated and mark as such
• Export fields as properties with getters/setters if deprecated and mark as such

4.0.0

• BREAKING: Drop support for py_generic_services as it was removed from the protobuf compiler starting in version 6.30
  • https://protobuf.dev/news/2024-10-02/#rpc-service-interfaces
• Drop testing support for protobuf <6.32 because they don't support editions
  • With some more work this could be added back in a testing refactor
  • Protobuf <6.32 still had the edition enums and field options, so it should still work. But is untested
• Add support for editions (up to 2024)
• Add generate_concrete_servicer_stubs option to generate concrete instead of abstract servicer stubs
• Add sync_only/async_only options to generate only sync or async version of GRPC stubs
• Switch to types-grpcio instead of no longer maintained grpc-stubs
• Add _HasFieldArgType and _ClearFieldArgType aliases to allow for typing field manipulation functions
• Add _WhichOneofArgType_<oneof_name> and _WhichOneofReturnType_<oneof_name> type aliases
• Use __new__ overloads for async stubs instead of TypeVar based __init__ overloads.
  • nipunn1313/mypy-protobuf#707
• Support file level field presence feature setting

3.7.0

• Mark top-level mangled identifiers as TypeAlias.
• Change the top-level mangling prefix from global___ to Global___ to respect Y042 naming convention.
• Support client stub async typing overloads
• Support PEP702 deprecations
  • Message deprecations are supported
  • Field deprecations are not. This may be possible with init overloads
  • Service deprecations are supported for Sync stubs
    • Not for async stubs
  • Enum message deprecation is supported
    • Enum field deprecation is not
• Drop Python 3.8 testing. Newer protobuf versions are incompatible. Generated code may still work

3.6.0
