        * linker error message improvements
        * better error checking in
        * can cast between pointers and integers
        * --traditional operator precedence conforms to qcc but --advanced to C

          compilation
        * much better qcc conformance in general for --traditional

        * non-const expressions for frame in state operator valid
        * computed functions for state think allowed
        * change --include FILE to pre-include a file rather than add a
          directory search path. Maps to -include FILE on the cpp command line.
        * all warnings (except for @self and self) are now fully controllable
        * --traditional now auto-inits uninitialized local vars
        * fast-float code option (defaults to on). kills almost 3000 statements
          from prozac
    o tools enhancements
        * wad utilty along the lines of pak. can't yet be used for wad creation
          (that's a little more complicated), but it can be used for listing
          and extracting the contents of a wad file. watch out for *foo :)
        * qfbsp
            - no longer zaps the bsp file when given a bsp instead of a map
              when compiling a map
            - watervis support
            - handle multiple wad files properly
            - better whilespace support for windows
            - bring in many of LordHavoc's changes to qbsp: HalfLife WorldCraft
              texture alighnment, partial "point of plane" autocorrection,
              hipnotic entity rotation
            - remove many arbitrary limits (edgs, points on windong, tokens and
              keys)
            - force axis aligned planes to truely be axis aligned (fixes
              degenerate polygons being generated by ClipWinding)
            - bsp to prt support (for watervising sourceless maps)
            - can now dump a map's textures to a wad file
            - various impovements from Vic via hqbsp (lordhavoc)
        * qflight
            - colored lighting support (from LordHavoc's hlight)
            - use vis data to speed up light passes
            - gzipped bsp support (reading only)
            - threading works
            - OpenQuartz's extentions (except -ikmap) brought in. id's light
              model is default
            - support properties files for setting default light settings for
              different light entity types
            - spotlight now works
        * pak
            - can specify files to extract from a pak
        * qfvis
            - support old-style portal files again
    o Progs engine/Ruamoko enhancements
        * Object root class revamped
        * progs debug/disassemble improvements
        * progs version update due to missing pointer in the symtab struct

        * progs string revamp: temp strings (eg, result from string + string)
          get freed when the creating funciton exits
        * new internal printf engine for progs
        * report all bad builtins rather than just the first. make the bad
          builtin number a warning and provide a suitable function in case the
          function is called: allows progs with bad (but unused) builtins to
          run anyway
        * progs dump print an address if the def name is blank
        * ruamoko math functions from Grievre
        * while not yet perfect, qfprogs now works with qfo files
        * new opcode: state.f. same as state, but takes a 3rd float operand to
          specify the step for calculating nextthink. accessed using
          [frame, think, step] (state is [frame, think])
        * progs handle x % 0 by giving a 0 result

Changes from 0.5.3
    o CRITICAL: exploitable buffer overflow in qw-server fixed
    o more gib regex and other text manipuation support
    o snd_oss_rw ditched in favour of just trying both ways

Changes from 0.5.2

    o General enhancements.
        * MVD playback in the qw clients.
        * MVD recording in the qw server.
          MVD support thanks to qwex 0.165b and highlander
        * sv_maxrate changes now take effect immediately rather than when
          clients (re)connect or change their rate
        * segfault when using "snd_output null" fixed
        * qw server "status" command now gives the server's uptime
        * "map" will display the amount of time the current map has been active
        * nq-server will now auto-load the start map if none is specified
        * streaming for large sound files
        * support for two channel sound files
        * partial string buffer audit
        * native Windows (win) sound driver finally works and is now default
        * DirectX sound support added (dx)
        * highchars stripped infokeys terminated properly so they don't contain
          garbage
        * WGL (nq-wgl.exe and qw-client-wgl.exe) resolution selection brought
          in line with all other targets giving the vid_width and vid_height
          cvars. Automatic aspect ratio support dropped.
        * X11 (nq-x11 and qw-client-x11) no longer hangs on 32bpp displays
        * new `view' system giving easier to control hud elements, centered
          menus and locatable scoreboard (hud_scoreboard_gravity)
        * OSS sound driver fixes: some kernel drivers need write only access,
          others need read/write
        * able to load/unload semi-arbitrary plug-ins using console commands
        * streaming for large sound files (eg., full length oggs)
        * stereo sample support
        * map command in the rcon admin list
        * configurable "quake" directory layout
        * server now actually runs properly when there's no network or
          console input (eg, bots continue to battle unattended)
        * skydome (gl_sky_clip 0) renders correctly
        * external entity file support (maps/foo.bsp will use maps/foo.ent if
          available)
        * map specific config files
        * map specific external textures in "textures/mapname/"
        * support for more tga formats
        * vid_conwidth cvar
        * cleaner mouse enter/leave handling for x11 and glx windows
        * hexenworld master server
        * software and gl (some cards) fish-eye support
        * "crosshair 3" for gl clients
        * remote screen shots work
        * curses console no longer default
        * more key-names supported
        * Matthew Wong's bsp2bmp `imported' as bsp2img. pcx output only
          currently.
        * console operator chat messages get echoed
        * BSD fseek bug fixed
        * no_pogo_stick 3 mode forcing friction independent of jump being
          active
        * rcon password /never/ gets written as it may be legitimate for
          another server (ie, confused person :)

    o GIB enhancements
        * events system (map change, client enter/leave etc)
        * several bug fixes
        * documentation

    o qfcc enhancements.
        * @argc and @argv deprecated in favor of @args.count and @args.list
          (@args is a struct with type @va_list)
        * structure copy
        * -L lib search paths and -l now behaves in a more expected manner
        * default search paths for includes and libs
        * updated man page and command line help
        * [super ...] messages work
        * categories work
        * nested and struct block initializers work
        * can access vector elements as vec.x as well as vec_x
        * void (void) func; is now valid (no params)
        * initialized globals can be used any place a true constant is expected

    o qfbsp/qflight/qfvis enhancements
        * various crash bug fixes
        * hint, skip and detail brush support
        * emit clipnodes in the correct order
        * groks quest's "map2" format in addition to the original format

    o Progs engine enhancements.
        * arbitrary size data copying
        * optionally handle division by 0 gracefully

Changes from 0.3.0

    o General enhancements.
        * NQ (quake1, single player, NetQuake, WinQuake) is back.
        * Video (driver and renderer), audio, gamecode (progs), console,
          model loading and general utility code shared in common libs between
          NQ and QW
        * Plugin system for sound and cd drivers.
        * Ogg Vorbis compression for sound effect samples (streamed ogg support
          is planned).
        * Menu system re-written in QuakeC/Ruamoko
        * Curses console for servers in Unix.
        * New key binding system.

    o Progs engine enhancements.
        * Fully modular. Mod/Server-independent, allowing for
          stand-alone QuakeC interpreter and client-side code.
        * The engine is no longer dependent on progdefs.h. This makes
          QuakeForge have trouble with QuakeC compilers that strip
          symbol names -- but those can be repaired using the new
          "qfdefs" tool.
        * New basic types, and instructions for using them, for version
          0.fff.002 progs (Quake's Version 6 is still supported).
        * Better dynamic string handling. Dynamic strings are
          garbage-collected.
        * Object-oriented runtime system, in the style of Objective-C.
        * Runtime fixups of built-in functions whose builtin number is
          zero. If a built-in function is available to the engine, with
          the same name given in the source code (e.g.
          "void (void) coredump = #0;"), the engine will set the value
          to the actual number used by the engine.
        * Debugging support (needs compiler support, which qfcc
          provides), including line-number information. Can display the
          line of text in the source on which an error occurred, if the
          new Cvar "pr_source_path" is set correctly.
        * Instruction-level code dumps are now formatted in an
          easier-to-read "assembly-code" format.

    o QuakeForge Code Compiler, qfcc -- a replacement for qcc.
        * Uses libQFutil for general utility functions such as hash
          tables, file access (incomplete), and pak files.
        * Uses libQFgamecode for progs information, such as opcode
          tables, enums, types, etc.)
        * Uses a lex/yacc (actually, Flex and Bison) scanner/parser
          architecture, like a "real" compiler does.
        * Drastically reduces the number of global defs needed for
          a given progs, by reusing temporary globals when possible.
        * All functions use the same block of defs for their local
          variables (compatible with all known servers), which further
          reduces the number of global defs needed.
        * Nested/chained function calls work properly.
        * Simple expressions, such as "a = b + c", compile to a single
          instruction instead of two, and do not use a temporary
          variable.
        * Local variables can be initialized to known values, as in
          "local float foo = 0.1;".
        * Uses the C preprocessor, so header files are now possible and
          useful.
        * The compiler checks for uninitialized and unused variables in
          functions, to help in finding errors.
        * The compiler can generate and use object files, for separate
          compilation (you don't have to compile all of your source all
          the time, only the parts that have changed). Normally, object
          files have a .qfo extension.
        * The compiler can link libraries, which are implemented as .qfo
          files inside pak archives.
        * The compiler implements stricter type checking, to assist in
          finding and fixing code errors.
        * The C language's "for", "do...while", and "switch" control
          structures have been adopted to provide a richer set of
          structures for programmers to use.
        * Additional functionality is given for progs that are to be
          used with QuakeForge's more advanced progs engine:

            x IMPORTANT:
              The order of operations is slightly different in "native"
              mode. The evaluation of "!foo & bar" is no longer
              "!(foo & bar)", but rather "(!foo) & bar". The new order of
              operations rules is more correct, but is different from how
              QCC evaluated. If you give the --traditional switch to
              qfcc's command-line, the old behavior is used.
            x The compiler now allows you to create your own functions
              that can accept a variable number of arguments, using the
              special "..." notation. The special constants "@argc" and
              "@argv" help with this. @argc contains the number of
              arguments, and @argv contains a list of those arguments. The
              handling of this is an improvement on C's vararg function
              handling, in our opinion, made possible by how the Quake
              system works.
            x New basic types: integer, pointer, enum, and id.
            x You can create new complex types, like arrays, structures,
              and unions, and allocate them at runtime.
            x String operators. You can add strings together to
              concatenate them, and you can compare their contents using
              the <=, <, >, >= operators.
            x The integer type has the full array of C operations
              available to it.
            x QFCC and QuakeForge now contain an object-oriented
              programming system, in the style of Objective-C and
              Smalltalk. It's *very* powerful, and can be used to create
              lots of interesting new things with rather little effort. If
              you don't wish to use the new system, you can safely ignore
              it with no danger to your code. :)
            x Special support for using the "self" special variable inside
              OO methods as well as the entity of the same name. If you
              use OO support for entities and want to assign a method as a
              touch/think/etc. function, "self" always refers to the
              object that "owns" the method being executed. The special
              variable "@self" was created to refer to the self entity.
              "@this" refers to the object.

    o Enhanced console scripting - GIB (GIB Isn't Bash)
        * New language derived from the quake console.
        * Functions with arguments and return values.
        * Looping (while, for) and branching (if) commands.
        * Local and global variables as well as access to cvars.
          Supports Python-like slicing of variables.
        * A basic math interpreter that respects order of operations
          and provides most arithmetic and logic operators.
        * Non-preemptive threading and callbacks to GIB functions in
          response to game events (limited but functional at the moment)
        * File reading, writing, and searching.
        * Integrates with console -- GIB functions can be exported as
          console commands to be used at the console or in binds.
        * See gib.html in doc for more information.

    o Enhanced time cheat ("speed cheat") protection
        * Time cheats only work for a split-second before protection
          kicks in.
        * Players moving with wrong timings are sped up/slowed down to
          the correct speed.
        * Delay before protection activates means that lag and normal
          network latency won't affect protection.
        * People who aren't really trying to cheat won't be kicked :)

    o Rendering enhancements
        * Experimental 32 bit software renderer.
        * Dynamic lights don't shine through walls.
        * Colored alias model lighting for GL.
        * Vertex Array use for sprites, particles and text. No fallbacks yet,
          so QF wont work with old or broken GL drivers. 
        * Switchable particle styles: r_particles_style 0 for Id. Default is 1,
          for lower particle count, larger texture particle effects.
        * 16 bit vertex alias model format.
        * Improved software gamma that more closely resembles hardware gamma.

Known problems in 0.5.2:
    o Doesn't work with 3dfx cards in MS Windows due to vertex array use.
    o SDL clients don't reliably support fullscreen mode in MS Windows
    o MS Windows support in general is sorely under-tested.
    o Starting an SDL client (-sdl, -sgl or -sdl32) in fullscreen mode
      and then going windowed requires in_grab to be toggled from 0 to 1
      and back to 0 before the mouse will be released.
