Support for python version > 3.8

[ajal-fh]

I would like to make a request for support for versions >3.8. While trying to install on python 3.11 for some packages like roslz4, tf2-py the installation fails. I would be happy to help if someone could guide on how to go about it. Thank you

After debugging I could see that ROS logging gets stuck indefinitely on python 3.11. Unsure how to solve this

Same issue here.

I also have this issue with roslz4.

Running this command in a freshly made conda environment with python 3.11.5, conda 23.10.0 and windows 10 enterprise leads to the following error:
pip install roslz4 --extra-index-url https://rospypi.github.io/simple/

  note: This error originates from a subprocess, and is likely not a problem with pip.
