- cibw now builds and uses bison 3.8.2 explicitly on platforms with no or out-of-date bison — AlmaLinux 8 only goes up to Bison 3.0 - cibw environment now includes `OPTFLAGS=-O3` to avoid generating debug info for abc, saving space in memory during linking - setup.py attempts to build `yosys-abc` independently first to avoid memory pressure from gigantic abc link step running in parallel with something else
