Apart from the usual bug and maintenance work, there are a number of StringDType related fixes for problems discovered during the ongoing string work in the main branch. This release supports Python versions 3.12-3.15 #### Changes - Casting a fixed-width byte string array (`np.bytes_`) to `StringDType` now raises `TypeError` when the bytes are not valid UTF-8. Previously the invalid bytes were stored as-is and later caused undefined behavior in string operations. ([gh-32296](numpy/numpy#32296)) - `MaskedArray._fill_value` would become stale when ufuncs that change dtype left the result holding a fill\_value typed for the old dtype. The mismatch was silent until something later called `_check_fill_value`, such as `.view()`, and then a `TypeError` would be raised. Now, when the copied fill\_value is no longer valid for the new dtype, fall back to the default fill\_value for that dtype instead of propagating the stale value. This may raise a `ComplexWarning` if the fill\_value is complex and the new dtype is real. ([gh-32423](numpy/numpy#32423)) #### Contributors A total of 9 people contributed to this release.

Backport of #32386.
Fixes #32373
PR summary
The duplicated file descriptor `fd2` was leaked which was created through Python’s `os.dup`.The fix was done by making the
osmodule reference retained until the conversion is finished. If 'fdopen' fails, the code callsos.close(fd2)before returning the existing error. Pairingos.closewithos.dupis also safer for Windows runtime ownership.The regression test makes
os.dupreturn an invalid descriptor (-2) sofdopenfails, records calls toos.close, confirmsnp.fromfileraises OSError, and verifies that the descriptor was passed to os.close.First time committer introduction
I use NumPy in machine-learning projects for numerical computations and data preprocessing, and this is my first contribution to NumPy.

I used Codex 5.6 Sol High for assistance with issue selection ,preparing the C fix, regression test, and verification and understanding the code.I have personally reviewed and understand the changes.
