1.2.103 (2005/Apr/07)

1.2.97 - 1.2.79 (2005/Jan/16 - 2004/Feb/18)

 - Fixed a problem with driver->recompile() in multi-level atomic code.
 - Input blocking didn't work properly as of the previous release, and input
   blocking for binary connections never worked at all.
 - Properly keep track of light-weight objects (bug introduced in last LWO
 - Fixed various bugs in asn_* kfuns and made the bit string functions more
   easily usable.
 - Added IPv6 support for unix.

 - IPv6 now works on Windows (XP SP1 and later).
 - Get DGD to work on Windows machines that don't have IPv6, too.

 - Fixed 2 bugs in the code optimizer.
 - The error "Non-numeric value in indexed string assignment" occurred in an
   inconsistent state.
 - Implemented object types: object "/path/to/obj" obj;
 - Implemented <- as an instanceof operator: obj <- "/path/to/obj"
   The second argument must be a string constant.  -> and <- have the same
 - Check parameters with the called, not the calling, frame.
 - Fixed a string reference problem during compilation.
 - Disallow (int) " 123", but allow sscanf(" 123", "%f", f), making both

 - The swapout callback function in the DGD extension interface is no longer
 - Call_touch() didn't work very well in atomic code.
 - Moved the O_PENDIO flag into the user struct as CF_OUTPUT.
 - O_LWOBJ is now a proper object flag.
 - Made sure that destructing the driver object in atomic code does not lead
   to trouble.

1.2.77 (2004/Feb/14)

 - Rather than causing an error, let the callout and precompiled object lists
   returned by status() be nil if they would not fit in an array.

1.2.76 (2004/Feb/05)

 - Two callouts started during the same thread will now always be executed in
   the proper order if the first has a delay N (milli)seconds larger than the
   second, even if DGD is delayed for more than N (milli)seconds between the
   first and the second callout (DGD/MP compatibility).
 - Make sure that a callout handle is not truncated to 16 bits before an
   attempt is made to remove it.
 - Include system files before DGD files on Windows.

1.2.75 (2004/Feb/01)

 - While restoring a callout, not all appropriate fields were zeroed.

1.2.72 (2004/Jan/24)

The typical way of changing the config file is to replace ({ 6047, 6048 }) with ([ "*":6047, "*":6048 ]). Note that these mappings may be empty, in which case no port is opened.

 - New kfun: datagram_challenge(), which replaces the return-TRUE-from-open()
   way of enabling datagram channels.  Multiple datagrams are now buffered per
 - Config file change.  ({ 6047, 6048 }) for ports changed to a mapping in
   which the address must also be specified: ([ "*":6047, "localhost":6048 ])

1.2.71 (2004/Jan/13)

There is a snag with upgrading the kernel library in a persistent mud: reboot the mud immediately after recompiling the driver object, before compiling anything else. UPDATE: as of the kernel library distributed with DGD 1.2.77, the driver object can be upgraded normally.

 - Fixed a bug in object upgrading, introduced with call_touch().
