Here is a mostly exhaustive list of the changes:
o Removes the SCRIPT_ENGINE_* status defines and replaces the
instances with regular boolean integer returns or changes the
procedure to return void. The latter case is better generally because
the caller ignores any status return (e.g. nmap.cc calling open_nse)
and/or the procedure raises a fatal error when unsuccessful.
o Moves the SCRIPT_ENGINE_LUA_DIR and the like to the nse_main.h header file.
o Removes the use of the SCRIPT_ENGINE_TRY (there was only one left)
and thus changes the call to l_dnet_open to a void function called
directly by luaopen_nsock (in nse_nsock.cc) instead of luaopen_nmap
(in nse_nmaplib.cc). I felt moving the function was also an
appropriate (but somewhat unrelated to the intent of the patch) change
as opening the dnet metatable is very related to opening up the
nsock library. This confines errors in opening the nsock library, including
opening the dnet metatable, to the call to luaopen_nsock.
o The FILES and DIRS defines are moved in to nse_fs.h where they are
more appropriate and localalized.
nse_main and nse_nsock. nse_main now uses Lua to create printable output
while a cleaner hexify procedure has been placed in nsock.
nse_string is removed as a result.
Visual C++ 2008 runtime components if they aren't already installed
on a system. These are some reasonably small DLLs that are
generally necessary for applications compiled with Visual C++ (with
dynamic linking). Many or most systems already have these installed
from other software packages. The lack of these components led to
the error message "The Application failed to intialize properly
(0xc0150002)." with Nmap 4.65. A related change is that Nmap on
Windows is now compiled with /MD rather than /MT so that it
consistently uses these runtime libraries. The patch was created by
Rob Nicholls.
Now does most of it's work through Lua:
From Nmap-dev: "Many of the changes consist of changing how Nmap interfaces
with Lua that were sometimes awkward or inflexible. Most of the functions
have been made to be callable directly by Lua which offers many technical
advantages: stack management is alleviated, errors are handled cleanly and
are more descriptive, and there is increased reusability."
Additionally:
-- Moved all lua_State * symbols from "l" to "L". This is to maintain
consistency with other Lua libraries (convention) and to make our macros portable.
-- Moved file system manipulation over to nse_fs.cc (from nse_init.cc)
The necessary libraries (lib and dll) and headers required for compilation and
linking are in mswin32/OpenSSL. A detailed upgrade guide is available in
mswin32/OpenSSL/upgrade-guide.txt.
Thanks to Thomas Buchanan for doing the initial work and writing up the initial
build guide.
My openssl-testing branch has been posted on nmap-dev for 12 days and has been
tested by (at least) Thomas, Jah and I, with no reports of failure.

Ensuring the safety of assert() calls by keeping NDEBUG undefined throughout
Nmap, Nbase and Nsock.
I've tested this on Linux and Windows XP without problems. On Windows I've
removed the definitions of _DEBUG and NDEBUG from the *.vcproj files.
