I put a source tarball up for 20.1.0a3, also in CVS as of now. This contains:
Konrad's fix to import_array
A new MA that pickles
A new package "Properties", that replaces MA.activeattr. Properties allows you to have properties such as MA/Numeric's shape attribute, that look like attributes but actually invoke functions on get, set, and/or delete. It can also be used to make attributes unwriteable or undeleteable. It doesn't have anything to do with Numeric but I use it in MA and kinds and don't have much else of an idea where to put it.
