Notes for BIND 9.19.1
---------------------

Security Fixes
~~~~~~~~~~~~~~

- None.

Known Issues
~~~~~~~~~~~~

- None.

New Features
~~~~~~~~~~~~

- Add DNS Extended Errors (:rfc:`8914`) when stale answers are returned from
  cache. :gl:`#2267`

- The Object Identifier (OID) embedded at the start of a PRIVATEOID public
  key in a KEY, DNSKEY, CDNSKEY, or RKEY resource record is now checked to
  ensure that it is valid when reading from zone files or receiving data
  on the wire, and the OID is now printed when the ``dig +rrcomments``
  option is used. Similarly, the name embedded at the start of a PRIVATEDNS
  public key is also checked for validity. :gl:`#3234`

- The Object Identifier (OID) embedded at the start of a PRIVATEOID
  signature in a SIG, or RRSIG resource record is now checked to
  ensure that it is valid when reading from zone files or receiving
  data on the wire.  Similarly, the name embedded at the start of
  a PRIVATEDNS public key is also checked for validity. :gl:`#3296`

- Catalog Zones schema version 2, as described in the "DNS Catalog Zones" IETF
  draft version 5 document, is now supported by :iscman:`named`. All of the
  previously supported BIND-specific catalog zone custom properties
  (``primaries``, ``allow-query``, and ``allow-transfer``), as well as the new
  Change of Ownership (``coo``) property, are now implemented. Schema version 1
  is still supported, with some additional validation rules applied from
  schema version 2: for example, the ``version`` property is mandatory, and a
  member zone PTR RRset must not contain more than one record. In the event of a
  validation error, a corresponding error message is logged to help with
  diagnosing the problem. :gl:`#3221` :gl:`#3222` :gl:`#3223` :gl:`#3224`
  :gl:`#3225`
