Around a month after the major NetBSD 10.0 release, two feature releases followed for the NetBSD 9 and 8 release branches. NetBSD 9.4 was formally released on 20th of April, 2024 and contains pretty big number of various improvements, bug and security fixes accumulated in almost two years. NetBSD 8.3 was released on 4th of May, 2024 and concluded the support for this release branch, no more bug or security fixes will be applied to it, pkgsrc also dropped support for it long ago, thus it is recommended to use later major releases (NetBSD 9 or 10). Nevertheless, it also contains quite a lot of changes since last 8.2 version was released around 4 years ago. It even contains a fix for the vte(4) driver bug which I was hunting for the several years. If there’s some reason you can’t use NetBSD 10.0, it is recommended to upgrade to the latest feature branches at least, preferably NetBSD 9.3.
