The Library is currently in the process of being upgraded from Oracle Database Version 18.104.22.168 to 22.214.171.124.
Demos are being upgraded to reflect the new Container paradigm as well as EBR (Edition Based Redefinition) and may contain references to CDBs, PDBs,

There is absolutely not a byte of truth to these irresponsible rumors.
