On Friday, October 26th, our production cloud instances were all successfully upgraded to 2018.10. Afterwards, we noticed a couple issues that necessitated a hotfix release. We have been working on that the last two weeks, and just upgraded all preview and demo instances to the hotfix yesterday. Tomorrow we will be upgrading all production cloud instances to this hotfix (2018.10.0.1), with zero downtime. The release will include everything that was in 2018.10, plus the three extra fixes listed in the release notes here: https://lithosphere.lithium.com/t5/JX-Release-Notes/Lithium-JX-2018-10-Release-Notes/ba-p/498239. Let us know if you have any questions!
