@item Targets
Using the new command @code{target}, you can select at runtime
whether you are debugging local files, local processes, standalone
systems over the serial port, realtime systems over a TCP/IP
connection, etc. _GDBN__ now uses a function vector to mediate access to
all the different possible targets, making it much easier to add
support for new remote protocols.

Internally, _GDBN__ now uses a function vector to mediate access to
different targets; if you need to add your own support for a remote
protocol, this makes it much easier.
@item Watchpoints
_GDBN__ now sports watchpoints as well as breakpoints. You can
use a watchpoint to stop execution whenever the value of an expression
changes, without having to predict a particular place in the inferior
process where this may happen.

@item Configuration
You must still choose a particular machine architecture and operating
system for _GDBN__'s host and target systems when _GDBN__ is built. The
script @code{config.gdb} now handles specification of separate host and
target configurations.
Compile-time configuration (to select a particular architecture and
operating system) is much easier. The script @code{config.gdb} now
handles specification of separate host and target configurations.
@item Interaction
_GDBN__ now uses the GNU readline interface to read its input; this
provides inline editing of commands, using the familiar Emacs or
@code{vi} keymaps, and command-history support. The user interface to
_GDBN__'s control variables has been simplified and consolidated in two
commands, @code{set} and @code{show}. Output lines are now broken at
readable places, rather than overflowing onto the next line.

lines are now broken at readable places, rather than overflowing onto

displaying only source language information.
@item Source Language
_GDBN__ now understands C++ source as well as C. Multiple inheritance is
supported when used with G++ 2.0. There is also limited support for C++
exception handling: _GDBN__ can break when an exception is raised,
before the stack is peeled back to the exception handler's context. You
can suppress output of machine-level addresses, displaying only source
language information.
