+* Sat Apr 03 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 1.26.0-15
+- Python:
+  * Stop using %%pyproject_buildrequires, since it is difficult to fit the
+    pyproject-rpm-macros build and install macros into this package, and Miro
+    Hrončok has advised that “mixing %%pyproject_buildrequires with
+    %%py3_build/%%py3_install is generally not a supported way of building
+    Python packages.”

 * Thu Mar 25 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 1.26.0-14
 - General:
   * Improved googletest source URL (better tarball name)
