+Subject: [PATCH] Fix invalid escape sequences for Python 3.15 compatibility
+
+Python 3.15 treats invalid escape sequences as SyntaxErrors rather than
+warnings. The strings in pytestmark contained '\_' which is not a valid
+escape sequence.
+
+Fixed by using raw strings (r-prefix) which is appropriate for regex
+patterns where backslashes should be literal.
+
+Fixes:
+  SyntaxError: "\_" is an invalid escape sequence

+Subject: [PATCH] Ignore h5py deprecation warning in pytest configuration
+
+h5py now emits a deprecation warning when creating datasets without
+specifying dtype. This warning is treated as an error by pytest,
+causing test failures with Python 3.15.
+
+Added filterwarning to ignore H5pyDeprecationWarning from h5py.
+
+Fixes:
+  H5pyDeprecationWarning: Creating a dataset without passing data or dtype
