It allows a stale RRset to be served directly from cache 208260f9a8Schristos for a period of time after a failed lookup, before a new attempt to 21b9eb1a82Schristos refresh it is made. :gl:`#2066` 228260f9a8Schristos 238260f9a8SchristosBug Fixes 248260f9a8Schristos~~~~~~~~~ 258260f9a8Schristos 268260f9a8Schristos- ``named`` could crash with an assertion failure if a TCP connection 27b9eb1a82Schristos were closed while a request was still being processed. :gl:`#2227` 288260f9a8Schristos 298260f9a8Schristos- ``named`` acting as a resolver could incorrectly treat signed zones 308260f9a8Schristos with no DS record at the parent as bogus. Such zones should be treated 31b9eb1a82Schristos as insecure. This has been fixed. :gl:`#2236` 328260f9a8Schristos 338260f9a8Schristos- After a Negative Trust Anchor (NTA) is added, BIND performs periodic 348260f9a8Schristos checks to see if it is still necessary. If BIND encountered a failure 358260f9a8Schristos while creating a query to perform such a check, it attempted to 36b9eb1a82Schristos dereference a ``NULL`` pointer, resulting in a crash. :gl:`#2244` 378260f9a8Schristos 388260f9a8Schristos- A problem obtaining glue records could prevent a stub zone from 398260f9a8Schristos functioning properly, if the authoritative server for the zone were 40b9eb1a82Schristos configured for minimal responses. :gl:`#1736` 418260f9a8Schristos 428260f9a8Schristos- ``UV_EOF`` is no longer treated as a ``TCP4RecvErr`` or a 43b9eb1a82Schristos ``TCP6RecvErr``. :gl:`#2208` 44*4bcbe0a3Schristos 45*4bcbe0a3SchristosKnown Issues 46*4bcbe0a3Schristos~~~~~~~~~~~~ 47*4bcbe0a3Schristos 48*4bcbe0a3Schristos- There are no new known issues with this release. See :ref:`above 49*4bcbe0a3Schristos <relnotes_known_issues>` for a list of all known issues affecting this 50*4bcbe0a3Schristos BIND 9 branch. 51
