Thanks! Could you, please, increment the version number here

micropython-ulab/code/ulab.c

Line 36 in e329206

#define ULAB_VERSION 6.4.2

, and add an entry here https://github.com/v923z/micropython-ulab/blob/master/docs/ulab-change-log.md?

Also, it would be great, if this error was addressed in https://github.com/v923z/micropython-ulab/blob/master/tests/2d/numpy/delete.py.

When you modify the unit test, you have to update the expected file: https://github.com/v923z/micropython-ulab/blob/master/tests/2d/numpy/delete.py.exp.
