aiohttp 3.12.9

on Python PyPI

Bug fixes

• Fixed IOBasePayload and TextIOPayload reading entire files into memory when streaming large files -- by :user:bdraco.

  When using file-like objects with the aiohttp client, the entire file would be read into memory if the file size was provided in the Content-Length header. This could cause out-of-memory errors when uploading large files. The payload classes now correctly read data in chunks of READ_SIZE (64KB) regardless of the total content length.
