~ Avoid using `/dev/null` for writing DEF files (it tries to create a temp file and fail) ~ PDK now has a default value of sky130A even outside the Makefile ~ PDK_ROOT now set automatically if Volare is installed ~ Upgrade to a newer version of OpenLane 2, which in turns uses `nix-eda` ~ Format nix packages using Alejandra ~ OpenROAD scripts now read liberty files before database files (they are linked together when the database is read) ~ Update Readme to remove Colab and add banner directing people to OpenLane 2
