New rules are now in effect for running 22 with a different version of libuv than the one used at compilation 23 time. These rules may trigger a fatal error at startup: 24 25 - Building against or running with libuv versions 1.35.0 and 1.36.0 is 26 now a fatal error. 27 28 - Running with libuv version higher than 1.34.2 is now a fatal error 29 when :iscman:`named` is built against libuv version 1.34.2 or lower. 30 31 - Running with libuv version higher than 1.39.0 is now a fatal error 32 when :iscman:`named` is built against libuv version 1.37.0, 1.38.0, 33 1.38.1, or 1.39.0. 34 35 This prevents the use of libuv versions that may trigger an assertion 36 failure when receiving multiple UDP messages in a single system call. 37 :gl:`#3840` 38 39Bug Fixes 40~~~~~~~~~ 41 42- :iscman:`named` could crash with an assertion failure when adding a 43 new zone into the configuration file for a name which was already 44 configured as a member zone for a catalog zone. This has been fixed. 45 :gl:`#3911` 46 47- When :iscman:`named` starts up, it sends a query for the DNSSEC key 48 for each configured trust anchor to determine whether the key has 49 changed. In some unusual cases, the query might depend on a zone for 50 which the server is itself authoritative, and would have failed if it 51 were sent before the zone was fully loaded. This has now been fixed by 52 delaying the key queries until all zones have finished loading. 53 :gl:`#3673` 54 55Known Issues 56~~~~~~~~~~~~ 57 58- There are no new known issues with this release.
