There’s a new version of Adobe’s Shockwave Player. It’s not clear when the new version appeared, since there was no official announcement. There’s nothing at all on the release notes page, other than the fact that the most recent version of Shockwave is 12.1.9.160.

You can download the new version from the main Shockwave page, which also shows the most recent version as 12.1.9.160. You can check what version of Shockwave is installed (if any) on your computer at the Shockwave Help page.
