Hi @sebheger and other maintainers

Any thoughts on doing a new release? Since 1.15.0 python-mip got python 3.12 and MacOS Mx support.

Thanks in advance,

@termoshtt
Constant constraints (#82)
1233f0e 
Constraint without any decision variable like following causes
segmentation fault in CBC solver with Python-MIP 1.15.
https://github.com/Jij-Inc/ommx/actions/runs/9698846012/job/26766373894

```python
    x = DecisionVariable.continuous(0)
    instance = Instance.from_components(
        decision_variables=[x],
        objective=x,
        constraints=[
            # 1 >= 0 is always true
            Linear(terms={}, constant=1) >= 0,
            x <= 1,
        ],
        sense=Instance.MAXIMIZE,
    )
```

This has been reported in
coin-or/python-mip#213 and some linked issues,
and fixed in coin-or/python-mip#237.

We use latest commit of Python-MIP
coin-or/python-mip@0ccb811
until the next version is released
coin-or/python-mip#384

A new release, including #377, is needed to work with the latest version of HiGHS (1.7.1)

Oi @tuliotoffolo, I saw you merged the latest PRs of this repo.
Could you help us with this?

Thanks in advance.

mip==1.15 still requires cffi==1.15 which does not have wheels for python > 3.10 (later version do).
Therefore, a new release would be highly welcome. Thanks in advance!

Until then pip install git+https://github.com/coin-or/python-mip.git
