Rails 8.1.4.1 Is a Big Security Release. Upgrade This Week.
Rails 8.1.4.1 is a security point release, and it’s a substantial one. It carries around a dozen CVE-level advisories spread across Action View, Action Pack, and Active Support. There are no feature changes to weigh and no behavior most apps need to plan around, which makes this the easy kind of upgrade to justify: bump it this week. (The fixes were also backported to the 8.0 and 7.x series, so you don’t have to be on 8.1 to get them.)
