Thanks for the extra context, and apologies for the difficulties you experienced. In most cases, fixing a current issue would be less problematic than rolling back a version, and we’ll document that better, along with possible recovery instructions.
With our commitment to testing, smooth upgrades, and responsive support we hope to mitigate any difficulties that would be experienced. When a severe bug is discovered we aim to have a patch released with no delay, and the sooner the issue is raised the quicker we can investigate – as was done when you reported your experience. We hope to avoid similar issues in the future, and appreciate your feedback and ideas to ensure that the CHT suits the needs of your deployments.
