Full Changelog

Changed

• Passing timeout=0 now raises a warning since it counterintuitively disables all retries. If you explicitly want to disable the timeout, use timeout=None.

Fixed

• _compute_backoff() no longer raises OverflowError when the attempt number exceeds 1024 with a float wait_exp_base. The exponential result is now clamped to wait_max on overflow. #137

26.1.0 - 2026-04-13

Changed

• Passing timeout=0 now raises a warning since it counterintuitively disables all retries. If you explicitly want to disable the timeout, use timeout=None.

Fixed

• _compute_backoff() no longer raises OverflowError when the attempt number exceeds 1024 with a float wait_exp_base. The exponential result is now clamped to wait_max on overflow. #137

25.2.0 - 2025-12-11

Removed

• Support for Python 3.8 and 3.9.

Added

• The type hints for our public API are now also verified using Pyrefly and ty. #124

• stamina.retry() now retries wrapped generator functions and async generator functions.

  Warning: Being able to asend and athrow into wrapped async generators introduced nontrivial complexity in the implementation and is therefore provisional. If supporting these features causes problems, they may be removed again in a future version. #123

• An on hook can now return a float or a datetime.timedelta to specify a custom backoff that overrides the default backoff. #103 #125

Fixed

• Prevent unbounded stop condition when both attempts and timeout are non-None falsy values. #109

• Default wait_exp_base parameter is now an integer to prevent an OverflowError after the 1023th retry. #104

• Attempt.next_wait now returns the correct value. #115
