Looking at the table on the AIX support lifecycle information page and the below, I would expect Dec 2025 for TL4 and July for SP1

Hello Anas,

thanks for the tip. That helps. The Release Notes are not available any earlier?
Too bad. But the release date will help planning our next upgrade.

hello Jeorge,

I have checked IBM's published lifecycle documentation, IBM announcements, and community sources, but was unable to locate an official release schedule or release notes availability for AIX 7.3 TL4 or a confirmed date for TL4 SP1.

Good Morning @all,

The announce letter is how IBM formally communicates the general availability date of product updates. Until then the release date is not public. The documentation updates for AIX 7.3 TL4, including release notes, generally become available about a week before the actual TL4 availability.
