Upper bound for `requires-python` breaks version resolution

[user1584]

What is happening?

During version resolution, e.g. by Poetry, a set of compatible libraries are searched. This search also takes the python versions into consideration that are specified in requires-python. Thus, if an app specifies a lower bound for the python version using >=3.10, all libraries must support python versions 3.10.0 and upwards. Some libraries, one of which is dash-bootstrap-components, specify the compatible versions with an upper limit (dash-bootstrap-components uses >=3.9, <4).
Since the app implicitly allows also python versions >3, Poetry will search for library versions that are compatible with python >3, which in case of dash-bootstrap-components would be version 0.10.5!
I totally get that you have no idea if dash-bootstrap-components will work with python 4,5,6,... but I guess you cannot guarantee that it will work with python 3.115.9 either. Thus, I would suggest to drop the upper limit.

What should be happening?

The current dash-bootstrap-components version should be selected for a python version specifier without upper limit.

Fair enough, have dropped the upper bound and will make a release in the coming week or so.

Have released version 2.0.1 which drops the upper bound.

pip install -U dash-bootstrap-components
