+Subject: [PATCH] Fix a numpy test for 32 bit archs
+
+The default dtype used in numpy array is "int". This type has
+different sizes on 32 and 64 bit architectures. The test tries to use
+the numpy array as a Long64_t dataframe. On 32 bit architectures this
+results in an error.
+
+This commit explicitly changes the numpy array's dtype to "int64" to
+match the Long64_t dataframe type on all architectyres.

+Subject: [PATCH] [PyROOT] Don't install the python modules twice
+
+The binary python modules were moved one directory level down into the
+ROOT and cppyy directories, so that they reside alongside the python
+files in the same directories. The install rule for the python files
+must therefore be extended to exclude the binary modules (PATTERN *.so
+EXCLUDE) so that these are not installed a second time overwriting the
+files installed by the install rule for the binary modules with another
+copy with the wrong file permissions.
+
+Also use the no-version option for the cppyy binary module as is
+already done for the pythonization binary module, since it is now
+installed in the python directory. Before it was installed in the
+library directory with an unversioned symlink in the python directory.

+Subject: [PATCH] [Python] Fix TF1 Pythonization test for NumPy 2.4.0
+
+The new NumPy 2.4.0 is more strict when implicitly converting 1-element
+arrays to scalars. It doesn't do that anymore, causing the TF1
+Pythonization tests to fail (see log below).
+
+This actually pointed to a real mistake in setting up the test, where a
+2D array was used to define the TFormula parameters while it should be a
+1D array.

+The commit 2605710bea7b1 changed from using the `ROOT::Detail::VecOps::`
+namespace explicitly for `IsSmall` to a `using` statement. However,
+there was also a remnant `IsSmall` function with an outdated
+implementation in the test file itself, which we can now remove.

-Therefore name of define is `OPENSSL_API_3_0`
-Meanwhile there is openssl 3.1 and 3.2.
-While seems to be there is no changes in API both can

+
+As we don't have a separate `cppyy_backend` anymore (neither as a Python
+package, nor as a shared library), trying to load the backend library
+will always give an exception that will be caught as an `ImportError`.
+
+It would be cleaner if this code branch is not even taken.

+Subject: [PATCH] [vecops] Adaptive size of long RVec instances in RVec test
+
+For the tests to make sense, some vectors need to be longer than the
+maximum small vector size. This maximum size is compiler and
+architecture dependent. For `RVec<int>` on ARM64 with gcc 14, the
+small vector capacity turns out to be 60, which is larger than the
+current test vector size of 18.
+
+Therefore, the test is refactored to adapt the large vector size
+automatically, according to the maximum small vector size.
