Hi All, On behalf of the NumPy team, I'm pleased to announce the release of NumPy 2.4.0rc1. The NumPy 2.4.0 release continues the work to improve free threaded Python support, user dtypes implementation, and annotations. There are many expired deprecations and bug fixes as well. This release supports Python versions 3.11-3.14. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/2.4.0rc1>; release notes and the changelog are available on Github <https://github.com/numpy/numpy/releases/tag/v2.4.0rc1>.
*Highlights* Apart from annotations and `same_value` kwarg, the 2.4 highlights are mostly of interest to downstream developers. They should help in implementing new user dtypes. - Many annotation improvements. In particular, runtime signature introspection. - New `casting` kwarg `'same_value'` for casting by value. - New `PyUFunc_AddLoopsFromSpec` function that can be used to add user sort loops using the `ArrayMethod` API. - New `__numpy_dtype__` protocol. *Contributors* A total of 141 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - !DWesl - !MyUserNameWasTakenLinux + - !ianlv + - !kostayScr + - !olivier + - Aadya Chinubhai + - Aaron Kollasch + - Abdu Zoghbi + - Abhishek Kumar - Abhishek Tiwari + - Adam Turner + - Akhil Kannan + - Aleksandr A.
