Thank you for the report. This probably requires implementing PEP 634 support.

Hi all, I use astor to process code, and encounter this problem. It seems this issue was solved at Apr 19, 2023, but the lasted version is 0.8.1 which released at on Dec 10, 2019. I would like to ask when the new version will be released？
