+[Jackson](../../../../jackson) (Java) data format module that supports reading and writing
 [CBOR](https://www.rfc-editor.org/info/rfc7049)
 ("Concise Binary Object Representation") encoded data.
 Module extends standard Jackson streaming API (`JsonFactory`, `JsonParser`, `JsonGenerator`), and as such works seamlessly with all the higher level data abstractions (data binding, tree model, and pluggable extensions).
 
+It also supports:
+
+* CBOR Sequences ([RFC-8742](https://www.rfc-editor.org/rfc/rfc8742.html)) (root-level value sequences)
+    * uses standard Jackson databind `MappingIterator` and `SequenceWriter` abstractions
+
 ## Status
 
 This module is considered stable and production quality (since 2.4). Similar to JSON- and other JSON-like
 backends, it implementsfull support for all levels (streaming, data-binding, tree model).

 ### Limitations
 
 Minor limitations exist with respect to advanced type-handling of `CBOR` format:
 
-* While tags are written for some types (`BigDecimal`, `BigInteger`), they are not handling on parsing

 * Streaming API (`CBORParser` and `CBORGenerator`)
 * Databinding (via `ObjectMapper` / `ObjectReader` / `ObjectWriter`)

 * Tree Model (using `TreeNode`, or its concrete subtype, `JsonNode` -- not JSON-specific despite the name)
