Release of OpenMC 0.12.2

Hi all. I’m happy to report that OpenMC 0.12.2 has just been released! This is small release that resolves a number of bugs and performance issues. Thanks to many of you on this forum who reported bugs and helped improve the code. Also thanks to the numerous contributors who added new features (a few notable new tally-related options) and reviewed pull requests.

As always, we recommend updating to the latest version of OpenMC if possible. If you are using conda, the new release should be available on conda-forge within the next few days.
