Notes for BIND 9.19.2
---------------------

Feature Changes
~~~~~~~~~~~~~~~

- New ``dnssec-policy`` configuration checks have been added to detect
  unusual policies, such as missing KSK and/or ZSK and too-short key
  lifetimes and re-sign periods. :gl:`#1611`

Bug Fixes
~~~~~~~~~

- The ``fetches-per-server`` quota is designed to adjust itself downward
  automatically when an authoritative server times out too frequently.
  Due to a coding error, that adjustment was applied incorrectly, so
  that the quota for a congested server was always set to 1. This has
  been fixed. :gl:`#3327`

- DNSSEC-signed catalog zones were not being processed correctly. This
  has been fixed. :gl:`#3380`

- Key files were updated every time the ``dnssec-policy`` key manager
  ran, whether the metadata had changed or not. :iscman:`named` now
  checks whether changes were applied before writing out the key files.
  :gl:`#3302`
