Like all of you, we have been watching with great interest as Big Blue transitions the IBM i software stack and Power10 hardware to cloud-like, utility-style subscription pricing.

There are some updates for the current releases of IBM i – that would be IBM i 7.4 and IBM i 7.5 that are both on standard support and IBM i 7.3 that is on extended support – and of course there are some new defective PTFs that Big Blue needs to make you aware of, as often happens because all modern platforms are complex and all of them sometimes have patches that have unintended consequences.
