Can I say Christmas has come early?
Today is the day the PTFs for the new Technology Refreshes for the current supported releases of IBM i are available:
7.5 TR17.4 TR7
If you want all of the new features and functions don’t forget to tell your System Administrator to download the PTFs for database, which includes SQL, and RPG too. Perhaps it would be easier to ask them to download all the latest CUM PTFs, which should include all of the TR PTFs.
