Hello!
Recently, Chef became aware of a security vulnerability in the version of libyaml we were using. We were nearing release for several of our products, and took the opportunity to do a sweep of some others.
The following releases are all live at this time, and while we are unaware of any scenarios by which your Chef environments may become compromised by the issues that these releases address, we urge you to upgrade to the appropriate versions at your earliest opportunity.
Please note that these releases do include other changes, which are detailed at the linked blog posts. Please contact support if you have any questions or concerns, and thanks for using Chef!
