The libxml 2.9 release notes appear comprehensive and make no mention of any backwards incompatibilities. bind9 appears to continue functioning correctly built and linked with libxml 2.9. Upstream don't appear to have a public bug tracker, but responded to my email quickly, telling me that 2.9 support has now been added to 9.6-ESV-R9, 9.8.5, 9.9.3 and 9.10.0. So it looks like it is safe to link against libxml 2.9.
No need to forward to Debian, as this doesn't currently affect Debian and bind9 in Debian will presumably be updated to the latest upstream when it does. Debdiff for Ubuntu attached. ** Attachment added: "debdiff" https://bugs.launchpad.net/ubuntu/+source/bind9/+bug/1164475/+attachment/3640491/+files/debdiff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1164475 Title: Missing dependency (libxml2) in raring To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bind9/+bug/1164475/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
