[Kea-users] [EXTERNAL] Kea 2.6.0 is released!

[Xiao, Yu (CCI-Atlanta)]

Hi ISC team,

I read the latest document on Kea 2.6.0 for new Hub and Spoke feature. In the beginning, we thought it could provide N+1 backup. But after I read your description and configuration example. I feel It’s more like multiple 1+1 backup, it requires the backup server has a 1-to-1 relationship with all the other primary servers. For each 1-to-1 relationship, it requires a different interface with both hosts on a different subnet. So if we need to protect N servers, we will need N interfaces and two IPs from each of N subnets on this central server. Is my understanding correct?


                            +----- Central Server ------+
                            |                           |
+----------+ relationship 1 |  +----------+----------+  | relationship 2 +----------+
| Server 1 |===================| Server 2 | Server 4 |===================| Server 3 |
+----------+                |  +----------+----------+  |                +----------+
                            |                           |
                            +---------------------------+





Best Regards,
Yu

Subject: [EXTERNAL] [Kea-users] Kea 2.6.0 is released!
ISC is excited to announce the release of Kea 2.6.0, the first version of the Kea 2.6 stable branch.

As a reminder: Internet Systems Consortium uses an alternating branch scheme for our releases. Branches that have an odd number in the digit after the first "." (for example: Kea 2.3, Kea 2.5) are development branches, while branches that are even-numbered are intended for stable production use (for example: Kea 2.4, Kea 2.6).

With the release of stable branch Kea 2.6, the Kea 2.5 development branch has now reached the end of its life and is no longer supported. The new Kea 2.7 development branch will be released in summer 2024.

There are now two stable Kea branches: Kea 2.4 (the most recent release is Kea 2.4.1, from November 2023), and the new Kea 2.6.0, released today. The Kea 2.2 branch has now reached End of Life.

----------

The 2.6.0 release contains the results of nearly a year's worth of development effort, previously previewed in the 2.5 development branch.

Highlights include:

  - Hub-and-spoke High Availability
  - New hook libraries
  - Support for more client options
  - Docker images
  - New Cloudsmith packages

and much more! Please read the full release notes at https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.0.

Kea 2.6.0 can be downloaded from: https://dl.cloudsmith.io/public/isc/kea-2-6/raw/versions/2.6.0/kea-2.6.0.tar.gz.

All current versions, along with the release notes and the Administrator Reference Manual (ARM), are also available via the ISC downloads page: https://www.isc.org/download.

A blog post with some more details about the new release is available at: https://www.isc.org/blogs/kea-2-6-0/.
