Hi Jaipaul,

Thanks for the upgrade, but this is failing in various ways.

First, some builds are failing, probably musl related:

ERROR: python3-3.15.0-r0 do_compile: oe_runmake failed
...

Then, when build succeeds, some test is failing:

Also, I'm adding back a link to the issues we had with 3.14.8 upgrade.
Some ptests were failing while building with musl. This might be fixed
by upstream, but it might be worth checking:
