ISC's Kea team members are proud and happy to announce the release of Kea 2.0.0.

2.0.0 is the first release of a new stable production branch of Kea,
representing the culmination of the work done in the 1.9.x experimental
development branch.  With this transition, the 1.9.x branch is ended and
a new development branch (2.1.x) will be started to continue development.

Also ending is support for Kea 1.6.x - ISC's intended policy is to support
two stable branches of Kea.  With this development those branches are
Kea 1.8 and Kea 2.0 and we recommend that any operators still running a
version prior to 1.8.2 make plans to upgrade, as the 1.6 branch is now
End of Life (EOL) and will not receive further bug or security fixes.

                         What's new in Kea 2.0.0?

The 2.0.0 release contains the results of a year's worth of development
effort, previously previewed in the 1.9 development branch.

Highlights include:

   - Better performance when using High Availability (HA)
   - Tunable parameters for more flexibility in high-traffic environments
   - Greater resiliency and improved handling of broken clients
   - Ongoing security improvements
   - New hooks
