This checks if the Library builds or if it is really compatible/works with multi-threading?

Currently, only testing the library installation; we will make progress to test the unittest result also.

> error: package `icu_properties v1.5.1` cannot be built because it requires rustc 1.67 or newer, while the currently active rustc version is 1.63.0

is this not environment problem?

Yeah, we still believe that a bunch of things should be updated to make the results more accurate.

But is there even an official docker image for deploying applications using 3.13t and 3.14t? Looking at https://hub.docker.com/_/python/ and https://github.com/docker-library/python/issues/947 , it seems to have been ignored. Without one, it's all useless. Almost no one wants to compile Python from source.

You don't have to build from source. uv is the best option, in my opinion, but the py-free-threading docs also have a longer list too:

uv: https://docs.astral.sh/uv/getting-started/installation/

py-free-threading: https://py-free-threading.github.io/installing-cpython/

docker: docker run -it quay.io/pypa/manylinux_2_28_x86_64 python3.13t
