>>> import titanlib
A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.2 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.
If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

I see that in the last few days this change has been made to the code (I don't know if it would solve my problem) but there hasn't been a new release.
In any case, would forcing the use of the old version be a temporary solution?
NumPy 2.0 has been released almost a year, there have been no more NumPy 1.x releases and I don't think there will be any more.
Are there any plans to add NumPy 2.x support?
I ask this also because there have been no more releases of titanlib since 2022 and I would like to understand if the development is still active.
