Fixed

• Peekable/Flatten drop order and leaks have been fixed.

• StepBy was misstepping by one on a fresh iterator.

• FusedLender/FallibleFusedLender were not implementing correctly last.

• TakeWhile was no honoring the fused contract.

[0.7.0] - 2026-05-31

New

• Functions __check_lender_covariance, __check_fallible_lender_covariance, __check_lending_covariance and __check_fallible_lending_covariance to check covariance of lenders and lends in custom implementations.

• Many sources and accessors are now const fn, so they can be used in const contexts (e.g., from_iter, from_into_iter, from_iter_ref, from_fn, once_with, windows_mut, and array_windows_mut).

Fixed

• find_map implementations were missing covariance checks.

• Removed spurious &'short reference from fallible covariance checks.

Changed

• Following std's policy, we have #[inline] on all public methods.

• We have now resolver = 3, which should solve some update issues with the maybe-dangling crate.
