I posted a separate note about 18.1 Beta, and just posted a general Announcement, but thought I would also point this thread at it too (to be all inclusive).
18.1 Release Discussion: 18.1 Release Plan
Release Notes and Downloads: https://github.com/PBSPro/pbspro/releases/tag/v18.1.beta
If you get a chance, please try it out and let the community know (file bugs, reply to the 18.1 discussion, message me directly, etc.)
Thx!
