+Subject: [PATCH] python/setup.py: remove unneeded wheel dependency
+
+wheel is required since version 3.13.0 and
+https://github.com/protocolbuffers/protobuf/commit/ff92cee10bcae7533b573368f448e782fbd43f39
+
+This will result in the following build failure when cross-compiling:
+
+Download error on https://pypi.org/simple/wheel/: unknown url type: https -- Some packages may not be found!
+Couldn't find index page for 'wheel' (maybe misspelled?)
+Download error on https://pypi.org/simple/: unknown url type: https -- Some packages may not be found!
+No local packages or working download links found for wheel
+
+Remove wheel requirement from setup.py as it is only needed by
+release.sh, not by setup.py
