 Microsoft released the SharePoint Framework version 1.18 on September 12th, 2023. And this release features one big change among a bunch of other updates such as core dependency upgrades.

Unlike earlier releases where I found lots of undocumented things, the official release notes are mostly complete. But just like prior releases, I did find a few additional nuggets in my research picking this release apart.
