+name: Dictionary updates
+about: Used to submit changes for vendor dictionaries or standards dictionaries
+---
+
+For dictionary changes please open pull requests for both the `master` and `v3.0.x` branches
+following the submission checklists below.
+
+*Note: The attribute referencing syntax in `master` has changed. When referencing nested
+attributes such as VSAs or TLVs the complete path is used. The reference string
+for the `Option-Request` attribute in the example below would be
+`Vendor-Specific.CableLabs.Option-Request`.
+This is why attribute prefixes are NOT used in the `master` branch.*
+
