From the Support’s Hot Topics email I learned the other day that MOS Note:742060.1 (Release Schedule of Current Database Releases) got updated with Oracle 18c information on January 18, 2018.
What got added to MOS Note:742060.1?
A column for Oracle 18c got added to the table of releases. You will find not information about potential release availability for Oracle 18c in the various options of the Oracle Cloud, and of course for on-premises as well.
Furthermore please find the updated graph as well.
The note below the graph is very important. See MOS Note:742060.1 for further details.
