# PyWavelets 0.5.1 Release Notes

PyWavelets 0.5.1 is a bug-fix release with no new features compared to 0.5.0

## Bugs Fixed

In release 0.5.0 the wrong edge mode was used for the following three deprecated modes: `ppd`, `sp1`, and `per`. All deprecated edge mode names are now correctly converted to the corresponding new names.

One-dimensional discrete wavelet transforms did not properly respect the `axis` argument for complex-valued data. Prior to this release, the last axis was always transformed for arrays with complex dtype. This fix affects `dwt`, `idwt`, `wavedec`, `waverec`.
