Announcing dhcp-3.0rc8

[Ted Lemon]

  *** From dhcp-announce -- To unsubscribe, see the end of this message. ***


I've just cut a new release candidate, which fixes a bunch of failover
problems as well as a couple of obscure core dumps.   This release
also includes some new documentation, courtesy of Wendy Verschoor, and
some OMAPI documentation for the client and server.

The release is in: ftp://ftp.isc.org/isc/dhcp

If you are running 3.0rc7, please try rc8 and let me know how it goes.

Thanks!

		Changes since 3.0 Release Candidate 7

- Fix a bug in failover where we weren't sending updates after a
  transition from communications-interrupted to normal.

- Handle expired/released/reset -> free transition according to the
  protocol specification (this works - the other way not only wasn't
  conformant, but also didn't work).

- Add a control object in both client and server that allows either
  daemon to be shut down cleanly.

- When writing a lease, if we run out of disk space, shut down the
  output file and insist on writing a new one before proceeding.

- In the server, if the OMAPI listener port is occupied, keep trying
  to get it, rather than simply giving up and exiting.

- Support fetching variables from leases and also updating and adding
  variables to leases via OMAPI.

- If two failover peers have wildly different clocks, refuse to start
  doing failover.

- Fix a bug in the DNS update code that could cause core dumps when
  running on alpha processors.

- Fixed a bug in ddns updates for static lease entries, thanks to a
  patch from Andrey M Linkevitch.

- Add support for Darwin/MacOS X

- Install omshell (including new documentation).

- Support DNS updates in the client (this is a very obscure feature
  that most DHCP client users probably will not be able to use).

- Somewhat cleaner status logging in the client.

- Make OMAPI key naming syntax compatible with the way keys are
  actually named (key names are domain names).

- Fix a bug in the lease file writer.

- Install DHCP ISC headers in a different place than BIND 9 ISC
  headers, to avoid causing trouble in BIND 9 builds.

- Don't send updates for attributes on an object when the attributes
  haven't changed.   Support deleting attributes on remote objects.

- Fix a number of bugs in omshell, and add the unset and refresh
  statements.

- Handle disconnects in OMAPI a little bit more intelligently (so that
  the caller gets ECONNRESET instead of EINVAL).

- Fix a bunch of bugs in the handling of clients that have existing
  leases when the try to renew their leases while failover is
  operating.
