[New-bugs-announce] [issue44418] unicodedata.ucnhash_CAPI removed from Python 3.10 without deprecation

[Miro Hrončok]

New submission from Miro Hrončok <miro at hroncok.cz>:

In bpo-42157, the unicodedata.ucnhash_CAPI attribute was removed without deprecation. This breaks at least https://github.com/dgrunwald/rust-cpython with:

    AttributeError: module 'unicodedata' has no attribute 'ucnhash_CAPI'

Please revert the removal and deprecate the attribute for 2 Python releases if you want to remove it.

Thanks
