Chef recently announced that all of its community cookbooks now require, at minimum, Chef 12.1. This recent change allows users to benefit from features like multi-package installation, new Ohai plugin data, and custom resources that are available only on Chef 12.
If you are an AWS OpsWorks Chef 11 user, you can:
· Pin the major version of the community cookbooks to retain cookbook compatibility.
· Upgrade to Chef 12 and enjoy the latest community enhancements.
If you are an AWS OpsWorks Chef 11 user who uses the built-in layers of OpsWorks, you can continue to operate your stacks without any disruption or changes.
