+From 57084ae28ed14f3bba89ab51104dd5521b7edb64 Mon Sep 17 00:00:00 2001
+From: Nathan Goldbaum <nathan.goldbaum@gmail.com>
+Date: Tue, 22 Apr 2025 15:31:14 -0600
+Subject: [PATCH] ENH: Support Python 3.14 (#28748)
+
+* MNT: use CPython internal APIs to hotfix temporary elision on 3.14
+
+This is based on a diff from Sam Gross, see
+https://github.com/numpy/numpy/issues/28681#issuecomment-2810661401
+
+* TST: use refcount deltas in tests that hardcode refcounts
+
+* TST: one more refcount test change I don't understand
+
+* TST: fix ResourceWarning
+
+* CI: add 3.14 and 3.14t linux CI
+
+* CI: try with setup-python instead of setup-uv
+
+* CI: fix 3.14t-dev cython install
+
+* Update numpy/_core/src/multiarray/temp_elide.c
+
+Co-authored-by: Ross Barnowski <rossbar@caltech.edu>
+
+* CI: drop linux 3.13t smoke test
+
+* TST: move refcount check inside with block
+
+* MNT: guard against a possible future PyPy 3.14
+
+---------
+
+Co-authored-by: Ross Barnowski <rossbar@caltech.edu>
+
+MNT: add support for 3.14.0b1

+  NumPy is a general-purpose array-processing Python package designed to
+  efficiently manipulate large multi-dimensional arrays of arbitrary
+  records without sacrificing too much speed for small multi-dimensional
+  arrays. There are also basic facilities for discrete fourier transform,
+  basic linear algebra and random number generation.
+  It is the successor of Numeric and numarray.
