-# Chef Client Release Notes 12.12:
-
-## Attribute read/write/unlink/exist? APIs
-
-On the node object:
-
-- `node.read("foo", "bar", "baz")` equals `node["foo"]["bar"]["baz"] `but with safety (nil instead of exception)
-- `node.read!("foo", "bar", "baz")` equals `node["foo"]["bar"]["baz"]` and does raises NoMethodError
-
-- `node.write(:default, "foo", "bar", "baz")` equals `node.default["foo"]["bar"] = "baz"` and autovivifies and replaces intermediate non-hash objects (very safe) 
-- `node.write!(:default, "foo", "bar", "baz")` equals `node.default["foo"]["bar"] = "baz"` and while it autovivifies it can raise if you hit a non-hash on an intermediate key (NoMethodError)
-- there is still no non-autovivifying writer, and i don't think anyone really wants one.
-- `node.exist?("foo", "bar")` can be used to see if `node["foo"]["bar"]` exists
-
-On node levels:
-
-- `node.default.read/read!("foo")` operates similarly to `node.read("foo")` but only on default level
-- `node.default.write/write!("foo", "bar")` is `node.write/write!(:default, "foo", "bar")`
-- `node.default.unlink/unlink!("foo")` is `node.unlink/unlink!(:default, "foo")`
-- `node.default.exist?("foo", "bar")` can be used to see if `node.default["foo"]["bar"]` exists
-
-Deprecations:
-
-- node.set is deprecated
-- node.set_unless is deprecated
-
-## `data_collector` enhancements
-
-- Adds `node` to the `data_collector` message
-- `data_collector` reports on all resources and not just those that have been processed
-
-## `knife cookbook create` is deprecated. Use the chef-dk's `chef generate cookbook` instead.
