Upgrade Guide

[1.2.5] to [2.0.0b1]

Updated package structures

Generated code now strictly follows the package structure of the .proto files. Consequently .proto files without a package will be combined in a single __init__.py file. To avoid overwriting existing __init__.py files, its best to compile into a dedicated subdirectory.

Upgrading:

• Remove your previously compiled .py files.
• Create a new empty directory, e.g. generated or lib/generated/proto etcetera.
• Regenerate your python files into this directory
• Update import statements, e.g. import ExampleMessage from generated
