I think we're in the clear! I was able to upgrade core and then Xo* without errors. I did get the following error, which appears to have occurred after the APM logic and the package version update (note the "Package enabled"):
Package enabled.Error: required argument 'key' is missing, should be: ::xo::xotcl_object_type_cache flush ?-partition_key /value/? /key/
Is this something you've seen before?
Thanks again!
