+Subject: [PATCH] truss-transfer: bump abi3 floor to py39
+
+Upstream-Status: Inappropriate [manylinux_2_39_riscv64 ships no cp38 interpreter]
+
+The riscv64 manylinux image's oldest available CPython is cp39 (no cp38),
+so a wheel built here and tagged cp38-abi3 (this crate's abi3-py38
+feature) would never actually be compiled or tested against its own
+declared floor. Bump the pyo3 abi3 feature to abi3-py39 so the riscv64
+wheel's tag matches the oldest interpreter it is built and tested on;
+every other platform's wheel is unaffected.
