The best thing to happen to OpenLane since OpenLane.
Variables related to output files: i.e. logs, results and reports, are becoming more uniform.
* Variables now point to folders
* Variables now called `{stage}_{type}s`
* All variables renamed to be tool-generic
* magic, klayout, cvc and lvs all unified, renamed "finishing"
* Better flow runtime calculation
* All step runtimes are now stored in a yaml file, which can easily be read by a human or parsed by a computer.
* Better step indexing
* You have to increment the step index explicitly using `increment_index`.
* Functions that take log arguments now require you to not use an indexed file, it's their responsibility to index them.
* Changed names for many logs to make more sense
* A plethora of files being moved and/or renamed
* Yosys scripts were moved into their own folder
* All references to OpenLANE that are not a published paper have been replaced with OpenLane
* Copyright dates updated on some files
