"Notes for BIND 9.11.17

Feature Changes

The configure option --with-libxml2 now uses pkg-config to detect
libxml2 library availability. You will either have to install pkg-config
or specify the exact path where libxml2 has been installed on your
system. [GL #1635]

Bug Fixes

Fixed re-signing issues with inline zones which resulted in records
being re-signed late or not at all."
