A new version of Shockwave appeared at some point in recent weeks. There was nothing like an announcement, and version 12.2.5.196 is barely mentioned on the official Shockwave release notes page. In fact, all we get is this: “Current Runtime Release Version: 12.2.5.196”.
Somewhere at Adobe, there’s at least one person who knows why Shockwave 12.2.5.196 was released. It would sure be handy if they said something about it.
If you use a web browser with Shockwave enabled, you should probably install the new version, because it may contain a security fix that Adobe just didn’t bother to mention.
