Welcome!

New version of Kea - 0.9.2 was released today!

Kea is an alternative DHCP implementation being developed by Internet
Systems Consortium, Inc. that features fully functional DHCPv4, DHCPv6
and Dynamic DNS servers. Both DHCP servers fully support server
discovery, address assignment, renewal, rebinding, release, DNS updates
and host reservation. The DHCPv6 server supports prefix delegation.

Version 0.9.2 adds the following features to Kea:
* statistics - Kea now records a number of measurements, e.g. number of
packets received, type of packets, or leases assigned;

* control channel - a control channel has been implemented. If
configured, it allows a system administrator to send commands to the
server. For 0.9.2 the commands supported are for retrieving, resetting
and removing statistics, but the number of commands is expected to grow
with each release;

* logging: new loggers - our logging system received a significant
upgrade. There are several new loggers specified, so it is now possible
to better fine tune logging;

* logging: new messages - many new log messages have been added, so
there is now a better trace of what is happening in the system,
especially in error conditions;

* logging: updated existing messages - many existing messages were
updated to include additional details;

* The KEA_HOOKS_VERSION symbol has been updated, so all hooks code will
need to be recompiled and re-linked against the new version of Kea, If
this is not done, Kea will log a HOOKS_INCORRECT_VERSION message and
refuse to load hooks libraries.

Note: when migrating from Kea 0.9.1 to 0.9.2:
* There is a new MySQL schema, reported as version 3.0. (Kea 0.9.1 used
schema version 2.0). The new schema introduces tables that will
eventually store host reservations. Although this version of Kea does
not make use of them, a future version will.  If you are using MySQL as
the database backend, it is suggested that the schema be updated now,
using the kea-admin tool. Further details can be found in the section on
kea-admin in the Kea guide (http://kea.isc.org/docs/kea-guide.html)

== Changes ==

The following summarizes changes and important upgrade notes since the
previous
release (0.9.2-beta). (See the git history for more details and additional
development.)

988.    [bug]        fdupont
    keactrl no longer returns an error when the "status" command is
    issued and the Kea configuration file doesn't exist.
    (Trac #3785, git a27d72ef3cb7640a41dca26c8728a9cbd9ad1ca9)

987.    [bug]        marcin
    Fixed textual representation of the options containing an array
    of 1 byte long unsigned numbers.
    (Trac #3959, git 9045fd9d6d282184cce10a622c0108abab029d5b)

986.    [bug]        marcin
    Fixed the failing lease allocation from the large address and
    prefix pools.
    (Trac #3958, git c86b6a68725e2f57679598ff4890fc82f4482c20)

985.    [bug]        marcin
    Eliminated extraneous debug-level DHCP6_RESPONSE_DATA entry from the
    DHCPv6 server log output.  Prior to this the server was logging
    each response twice.
    (Trac #3949, git 023973cbce44e5fb92a2bc45e69f2786d5152091)

984.    [bug]        tmark
    Replaced use of "kill -0" with "ps -p" in keactrl when
    checking if servers are alive.  This makes it possible for
    non-root users to use keactrl to monitor server status.
    (Trac #3954, git f7f22b244343a3dc2d06645a47c2c65a5134326e)

983.    [bug]        fdupont
    Enforce numeric month values in Posix date printing.
    (Trac #3944, git fdbe74b0235055057a37c6ce2b0aaf88f0cc7891)

982.    [bug]        marcin
    Fixed the typo in the name of the D2 logger.
    (Trac #3951, git 92305b2a1774df1cf1bdfeb93d787fea0ab27f74)

981.    [bug]        tmark
    keactrl now uses PID files to identify and control server instances.
    Prior to this it relied on the system command, "ps", which could lead
    to it misinterpreting which processes are or are not running.
    (Trac #3939, git 93a720ed7ffdffe66bd835cd64f78e4ad601637a)

980.    [doc]        marcin
    Updated Developer's Guide.
    (Trac #3484, git 220c337c31a592311363eca981c7f1578abbe15d)

979.    [bug]        fdupont
    Fixed two cases of public variables in a base class being
    hidden by variables in a derived class.
    (Trac #3920, git bd42a66fb67aab3fe397523c6fdbf14a939587c8)

978.    [func]        tmark
    DHCPv4, DHCPv6, and DHCP_DDNS now all create PID files upon
    startup.  The PID file pathname is formed from:
        <localstatedir>/<conf name>.<binary-name>.pid
    If a server's PID file exists and contains the PID of a
    live process, it will emit a log message and exit.
    (Trac #3769, git cdce632add025aaadbcdc89078f5bd3e19cfb5ca)

977.    [doc]        tomek
    Frequently Asked Questions section added to the Kea User's Guide.
    (Trac #3873, #3847, git 95683c9d3c3dd7024269df1904b6cbe5817741a2)

976.    [build]        tomek
    Included missing Doxygen documentation images in the tarball.
    (Trac #3928, git 2fb63a18897b93b12a5fc4635d4ac29e0bf82841)

975.    [doc]        marcin
    Updated the list of standard DHCPv4 options in the User's Guide
    with the information of whether they are returned by the server
    even when they are not requested.
    (Trac #3578, git b361b28ce53729a5f2d59f79670a36cf1a4a0352)

974.    [bug]*        marcin
    Corrected invalid format of the DHCPv4 option 5 (name-servers).
    The corrected format comprises a list of IPv4 addresses,
    rather than a single IPv4 address.
    (Trac #3887, git 54d1dbe6138e74c5efacfbaf85b77c87aea9ddf1)

973.    [doc]        marcin
    Added new section to the User's Guide to describe the issues
    with unicast responses to the DHCPINFORM messages when ARP
    traffic is blocked.
    (Trac #3740, git 22bcb060ceca544dfa1779815321155668bf19dc)

972.    [doc]        marcin
    Updated sections of User's Guide concerning creation of
    the option definitions and Vendor Specific Information
    options for both DHCPv4 and DHCPv6.
    (Trac #3846, git 6aebe0867ca9cf6fb09a289d80051125db7fa34b)

971.    [func]        fdupont
    Changed all occurrences of unlink() to the more portable remove()
    to avoid problems on operating systems where the former is not
    available.
    (Trac #3841, git 3752529ed3d72137f6899ef8225a0b231db5b1f0)

970.    [bug]        fdupont
    Refactored some code to suppress cppcheck warnings.
