GNU Units 2.12 has been released. The most significant changes:
* Updated and revised units database, with constants now based on 2014 CODATA. * Readline history is persistent and is saved to ~/.units_history, or to the file specified with --history (-H) option. * Comments allowed on interactive input with '#', most useful with logging. * Various bug fixes -- If you have a working or partly working program that you'd like to offer to the GNU project as a GNU package, see https://www.gnu.org/help/evaluation.html.
