+In previous versions of the DHCP server there was a mechanism whereby

people here, both for working on the code and for prodding me into
improving it.
+ Changes since 3.0 Beta 2 Patchlevel 22
+
+- Apply some patches suggested by Cyrille Lefevre, who is maintaining
+ the FreeBSD ISC DHCP Distribution port.
+
+- Fix a core dump in DHCPRELEASE.
+
+ Changes since 3.0 Beta 2 Patchlevel 21
+
+- This time for sure: fix the spin described in the changes for pl20.
+
+ Changes since 3.0 Beta 2 Patchlevel 20
+
+- Fix a problem with Linux detecting large numbers of interfaces (Ben)
+
+- Fix a memory smash in the quotify code, which was introduced in
+ pl19.
+
+- Actually fix the spin described in the changes for pl20. The
+ previous fix only partially fixed the problem - enough to get it
+ past the regression test.
+
+ Changes since 3.0 Beta 2 Patchlevel 19
+
+- Fix a bug that could cause the server to abort if compiled with
+ POINTER_DEBUG enabled.
+
+- Fix a bug that could cause the server to spin when responding to a
+ DHCPREQUEST.
+
+- Apply Joost Mulders' suggested patches for DLPI on x86.
+
+- Support NUL characters in quoted strings.
+
+- Install unformatted man pages on SunOS.
+
+ Changes since 3.0 Beta 2 Patchlevel 18
+
+- Allow the server to be placed in partner-down state using OMAPI.
+ (Damien Neil)
+
+- Implement omshell, which can be used to do arbitrary things to the
+ server (in theory). (Damien Neil)
+
+- Fix a case where if a client had two different leases the server could
+ actually dereference the second one when it hadn't been referenced,
+ leading to memory corruption and a core dump. (James Brister)
+
+- Fix a case where a client could request the address of another client's
+ lease, but find_lease wouldn't detect that the other client had it, and
+ would attempt to allocate it to the client, resulting in a lease conflict
+ message.
+
+- Fix a case where a client with more than one client identifier could be
+ given a lease where the hardware address was correct but the client
+ identifier was not, resulting in a lease conflict message.
+
+- Fix a problem where the server could write out a colon-seperated
+ hex list as a value for a variable, which would then not parse.
+ The fix is to always write strings as quoted strings, with any
+ non-printable characters quoted as octal escape sequences. So
+ a file written the old way still won't work, but new files written
+ this way will work.
+
+- Fix documentation for sending non-standard options.
+
+- Use unparsable names for unknown options. WARNING: this will
+ break any configuration files that use the option-nnn convention.
+ If you want to continue to use this convention for some options,
+ please be sure to write a definition, like this:
+
+ option option-nnn code nnn = string;
+
+ You can use a descriptive name instead of option-nnn if you like.
+
+- Fix a problem where we would see a DHCPDISCOVER/DHCPOFFER/
+ DHCPREQUEST/DHCPACK/DHCPREQUEST/DHCPNAK sequence. This was the
+ result of a deceptively silly bug in supersede_lease.
+
+- Fix client script exit status check, according to a fix supplied by
+ Hermann Lauer.
+
+- Fix an endianness bug in the tracefile support, regarding ICMP
+ messages.
+
+- Fix a bug in the client where the medium would not work correctly if
+ it contained quoted strings.
+
+ ** there was no pl17 **
+
+ Changes since 3.0 Beta 2 Patchlevel 16
+
+- Add support for transaction tracing. This allows the state of the
+ DHCP server on startup, and all the subsequent transactions, to be
+ recorded in a file which can then be played back to reproduce the
+ behaviour of the DHCP server. This can be used to quickly
+ reproduce bugs that cause core dumps or corruption, and also for
+ tracking down memory leaks.
+
+- Incorporate some bug fixes provided by Joost Mulders for the DLPI
+ package which should clear up problems people have been seeing on
+ Solaris.
+
+- Fix bugs in the handling of options stored as linked lists (agent
+ options, fqdn options and nwip options) that could cause memory
+ corruption and core dumps.
+
+- Fix a bug in DHCPREQUEST handling that resulted in DHCPNAK messages
+ not being send in some cases when they were needed.
+
+- Make the lease structure somewhat more compact.
+
+- Make initial failover startup *much* faster. This was researched
+ and implemented by Damien Neil.
+
+- Add a --version flag to all executables, which prints the program
+ name and version to standard output.
+
+- Don't rewrite the lease file every thousand leases.
+
+- A bug in nit.c for older SunOS machines was fixed by a patch sent in
+ by Takeshi Hagiwara.
+
+- Fix a memory corruption bug in the DHCP client.
+
+- Lots of documentation updates.
+
+- Add a feature allowing environment variables to be passed to the
+ DHCP client script on the DHCP client command line.
+
+- Fix client medium support, which had been broken for some time.
+
+- Fix a bug in the DHCP client initial startup backoff interval, which
+ would cause two DHCPDISCOVERS to be sent back-to-back on startup.
+
+
+ Changes since 3.0 Beta 2 Patchlevel 15
+
+- Some documentation tweaks.
+
+- Maybe fix a problem in the DLPI code.
+
+- Fix some error code space inconsistencies in ddns update code.
