Bug fixes
Warning: Kea DHCP High Availability (HA): Making
configuration changes through Micetro, such as creating
or deleting DHCP scopes, may cause HA communication to fail when running Kea DHCP
3.0 with multithreading enabled. In affected versions, the Kea HA nodes stop
listening on the HA communication port, causing heartbeat failures and resulting in
the HA pair entering a partner-down state.
This behavior is caused by an ISC Kea defect tracked as ISC Kea GitLab issue #4145. This issue affects Kea 3.0 versions available at this time, which include up to 3.0.3. The ISC Kea 3.2.0 release notes indicate that the related defect was fixed in that release and is expected to be backported to Kea 3.0.4.
Customers experiencing this issue should upgrade to Kea 3.0.4 once it becomes available (KI-027334)
- Dialogs with tabs, like the Edit user dialog, are now displayed correctly in Firefox web browsers (KI-027313)
- Fixed an issue in which a primary server's DNS agent address was added to the list of primary servers when creating a standalone secondary zone on a Microsoft DNS service (KI-026926)
- Fixed an issue in which modification of DHCP reservations on Kea DHCP servers resulted in a mismatch between the active lease and the new reservation (KI-026164)
