# PyWavelets 1.0.1 Release Notes

PyWavelets 1.0.1 is a bug-fix release with no new features compared to 1.0.0.

## Bugs Fixed

Key-based assignment of coefficients to a `FswavedecnResult` object (i.e. via its __setitem__ method) has been fixed.

The order that the individual subband coefficients were stacked by the function `pywt.ravel_coeffs` is now guaranteed to be consistent across all supported Python versions. Explicit alphabetic ordering of subband coefficient names is used for consistent ordering regardless of Python version.
