--------------------+--------------------
 There was a bug in the 3.8.0 version of py-sip. This bug was fixed [two
 weeks](https://www.riverbankcomputing.com/hg/sip/rev/67e0294b505c) ago in
 3.8.1.
 This also solved [68828](https://trac.macports.org/ticket/68828).
 Now the 3.8.1 is available. Somehow the old code ended up in the builds of
 the pre-build 3.8.1 version.

 This can be checked in for example the file:
 https://packages.macports.org/py311-sip/py311-sip-6.8.1_0.darwin_22.arm64.tbz2

 There we see the old code:
 ```
 opt/local/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11
 /site-packages/sipbuild/generator/outputs/code.py
 8417:    if klass.docstring is None or klass.docstring.signature is not
 SocstringSignature.DISCARDED:
 ```

 I don't understand how this old codes ends up in this file. I checked the
 [distfile](https://ftp.fau.de/macports/distfiles/py-sip/sip-6.8.1.tar.gz)
 and that contains the correct code (without the typo *Soc*string).
