+ - Node-RED now requires Node.js 12.x or later.
+
+ - The following nodes have had significant dependency updates. Unless stated,
+   they should be fully backward compatible.
+
+   - RBE:  Relabelled as 'filter' to make it more discoverable and made part of
+     the core palette, rather than as a separate module.
+   - Tail: This node has been removed from the default palette. You can reinstall it
+     from node-red-node-tail
+   - HTTP Request: Reimplemented with a different underlying module. We have
+     tried to maintain 100% functional compatibility, but it is possible
+     some edge cases remain.
+   - JSON: The schema validation option no longer supports JSON-Schema draft-04
+   - HTML: Its underlying module has had a major version update. Should be fully
+     backward compatible.
