Kea 2.0.2, March 2nd 2022, Release Notes

Welcome to Kea 2.0.2, a maintenance release of the stable 2.0 branch.
Kea is a DHCP implementation developed by Internet Systems Consortium
(ISC) that features DHCPv4 and DHCPv6 servers with DNS update and a
RESTful API; optional database support (MySQL and PostgreSQL); optional
RADIUS, Kerberos, and Yang/NETCONF support; and much more. Kea provides
extensive management capabilities, including but not limited to: TLS
support, runtime configuration monitoring and updates via a RESTful API,
host reservations, client classification, and more.

The text below references issue numbers. For more details, visit the Kea
GitLab page at https://gitlab.isc.org/isc-projects/kea/issues.

If you are upgrading from the previous stable version, the following
deficiencies have been addressed since Kea 2.0.1:

1. **Flex-id bugfix**: Fixed race condition on initialization of the
`flex_id_expr` member when using multi-threading in the Flexible
Identifiers hook library [2270].

2. **Literal IPv6 address in HA**: The Kea configuration for a High
Availability (HA) peer now accepts an IPv6 address as a valid value for
the `url` entry [#2302].

3. **Config Backend and client class options**: Kea core logic now
ensures options belonging to client classes are properly created when
classes are read from configuration backends [#2301].

4. **CentOS 8 packages retired**: Since CentOS 8 has reached end-of-life
and its repositories are no longer available, ISC can no longer generate
packages for CentOS 8. Users of CentOS 8 should upgrade, use a different
distribution, or compile Kea from sources. Using any system past its EOL
date is highly discouraged.
