# NOTE: as of late 2020, yosys has switched to an automation robot that
# automatically tags their repository Makefile with a new build number every
# day when changes are committed. please MAKE SURE that the version number in
# the 'version' field exactly matches the YOSYS_VER field in the Yosys
# makefile!
#
# if a change in yosys isn't yet available under a build number like this (i.e.
# it was very recently merged, within an hour), wait a few hours for the
# automation robot to tag the new version, like so:
#
# https://github.com/YosysHQ/yosys/commit/71ca9a825309635511b64b3ec40e5e5e9b6ad49b
#
# note that while most nix packages for "unstable versions" use a date-based
# version scheme, synchronizing the nix package version here with the unstable
# yosys version number helps users report better bugs upstream, and is
# ultimately less confusing than using dates.
