bpo-32424: Deprecate xml.etree.ElementTree.Element.copy() in favor of copy.copy() by GPHemsley · Pull Request #12995 · python/cpython (original) (raw)

Also, I can't find any record of copy ever having been available in the C implementation; it looks like it was __copy__ from the beginning.

The first appearance of copy in the Python implementation was in f15351d (first released in Python 3.1 and 2.7.4), which deemed it "experimental". 84fae78 (first released in Python 3.4) removed that designation when switching from comments to docstrings.
