Description of problem:
As of writing BIND 9.12.x is the current stable series of BIND, see also:
Once it comes to IDN2008 support, BIND 9.13.x would be appreciated.
Version-Release number of selected component (if applicable):
BIND 9.12.x or 9.13.x
Cross-filed case 02260329 in the Red Hat customer portal.
RHEL is an Enterprise distribution aimed to provide a stable platform for customers, to deploy they workloads. For this reason, we want to use upstream versions with longer support, if there are such versions. Current version of BIND in RHEL-8 is 9.11, which is an ESV (Extended Support Version) with EOL currently set to Dec 2021. This is the main reason why we chose 9.11 version for RHEL-8. The version is still relevant.
Version 9.12 has EOL set for April 2019, which is not really suitable for RHEL.
Additionally 9.13 is Unstable Development release, also not suitable for RHEL.
Another potential problem is that ISC DHCP uses BIND libraries for building. However ISC DHCP can not be built against BIND 9.12 or later.
If you are missing specific features in RHEL-8 version of bind, please provide us an explicit list with business case (use case) for each of them, to help us prioritize your request.
We may consider including a newer version of BIND in future releases of RHEL-8, but for now, this is not planned.
If there is a demand for automatic disabled IDN2008 in dig for command line usage, we are able to provide it in 9.11 version as well. If some features not available in bind 9.11 are required, please name explicitly which missing features are important to the customer.
I've updated GSS case 02260329 with the business justification. Technical extract:
- stale-answer-enable, stale-answer-ttl and max-stale-ttl options
- new-zones-directory option, see also GSS ticket 01597035 and bug #1315821
- Full IDNA 2008 support, see also bug #1098783

This is the only feature missing in current bind. It has to be backported.

This bug is solved the same way as on RHEL 7. new-zones-directory option is not supported. However bind home at /var/named is made writeable by named, making default configuration working without additional tweak. Backport is possible but unnecessary.
> - Full IDNA 2008 support, see also bug #1098783
Sure, this is already in place, support for IDN 2008 is already supported in both RHEL 7 and RHEL 8.
Created a new bug for stale cache feature: bug #1664863
Bug for the only missing feature from comment #5 is being tracked in bug #1664863. As mentioned in comment #2, we currently don't plan to update BIND to 9.12 or 9.13 version. We will most probably revisit the potential update of BIND once there is a new *ESV* version of BIND.
