BreakingUpgrade verdict

3 breaking changes and a platform requirement change.

In plain terms
  • Options for shifting that were already deprecated are gone; code using them must switch to the replacement.
  • An old option that was already marked deprecated has been removed, so code still passing it will fail.
  • You must now pass transform constructor arguments by name rather than by position.
  • This version no longer works on Python 3.10; you need a newer Python.
Must act Top 5 of 16 that need code or config changes

Python requirement changed in 0.26.0rc0: >=3.10 → >=3.11.
