[Announce] kdb v1.5-beta1 is available

[Keith Owens]

Typical, send the patch out and find a bug 30 seconds later.  Setting
breakpoints in initial commands (kdb_cmds) defines the breakpoints but
they are not activated until you enter and leave kdb at least once.  If
you need breakpoints in kdb_cmds, there is a workaround.  Boot with
'kdb=early' on the command line and just type 'go' at the first kdb
prompt.  Will be fixed in beta2.
