Supported Python Versions

pylint-protobuf supports Python 3.5 at a minimum.

Known Issues

pylint-protobuf does not currently support the following concepts from the protobuf specification:

• oneof fields
• repeated fields
• TypeError on field assignment

Externally defined message types are currently uninferable and so checking fields on message types may fail.
