+This file tries to organize and describe the changes between releases.
+Changes are broadly classified into the following categories:
+- New Features: These are either elements of the original games that
+  were first implemented in this release, or actually new capabilities
+  that are visible to the user.
+- Bugfixes: The removal of visible Bad Things from the code.
+- Internal Changes: The removal of invisible Bad Things from the code,
+  or changes in the way the program itself is structured.  These are
+  unlikely to be of interest to you unless you plan on coding
+  extensions.
+			     Version 0.6
+			    -------------
+- Netplay!  You can now engage in Super Melee over the Internet.
+- Key configuration is now entirely in-game.
+- UQM now compiles and runs on 64-bit systems.
+- The Quit button (F10) now works properly when used during the
+  introduction sequence.
+- Various small fixes to text and conversation logic.
+- The setup menu now reads all its text from the content, easing
+  translation.
+- The MOD player for PC-style music can now be linked against an
+  external version of libmikmod.
+- Various code cleanups and memory optimizations.
+			     Version 0.5
+			    -------------
+- The Starmap is searchable!  Type / then the beginning of the
+  constellation name, and you can tab through all possible
+  completions.
+- New 'hq' scaler, based on Maxim Stepin's "HQ2X" scaler.  See
+  www.hiend3d.com/hq2x.html for more details.
+- Scalers can use MMX/SSE/3DNow! instructions for significant speed
+  improvements.  The "Processor pack" is necessary for compilation of
+  same on VC6.
+- Imported DOS versions of many graphics; these have richer palettes
+  and so generally look better
+- There's a proper credit roll at the end of the game now.
+- Superior Planet handling: topographical maps scaled far more
+  precisely; optional 3DO-style throbbing slave shield; planets are
+  finally rotating spheres instead of spotlit cylinders or rectangles.
+  The old PC-style "Entering Planetary Orbit..." screen is back.
+- Setup Menu far more complete and easy to use, and selections made in
+  the Setup Menu will actually persist when you restart the program
+- Added support for the Tremor Ogg Vorbis decoder (avoids floating point
+  math)
+- Home, End and BackSpace keys work as you'd expect in text input.
+- Most of the game works with Unicode properly now, and so, with proper
+  font characters installed, will work with non-Latin alphabets.  (On
+  Windows, Unicode input requires a very recent version of SDL.)
+- Text may be input with the joystick again, as on the 3DO.  The
+  available characters are stored in content/lbm/joyalpha.txt.
+- The intro now plays only when a new game is started.
+- Color depth is now determined entirely automatically.
+- Only SELECT and CANCEL trigger the fade-to-black at the end of a
+  Super Melee, solving the issue of invisible "Really Quit?" menus for
+  Super Melee.  The "quit during fades" problem in general is still
+  extant.
+- Many dialog, and comm animation, and general graphical fixes
+- Keypress status is not reset when entering battle mode, so (for
+  instance) Melnorme ships can continue to charge a shot across
+  battles.
+- The Melnorme would occasionally strip off Plot Points as part of a
+  fuel deal.  No longer.
+- Bugs in the original code prevented certain ships from properly
+  spawning in "uncontrolled" space.  The "wilds" are now a bit wilder,
+  as apparently originally intended.
+- Venus's atmospheric density was incorrectly corrected in the 3DO
+  version.  It's been correctly corrected now.
+- Scheduled plot events work properly, even when the game suddenly
+  skips ahead in time.
+- Fixed version checking in unix build scripts. SDL 1.2.10 is now
+  recognised as newer than 1.2.9.
+- Spliced communications can be safely skipped past now.
+- Fixed fast escape weirdness (bug #619)
+- Threading system no longer assumes that there is no thread 0; this
+  permits compilation on AmigaOS.
+- Relative paths and fallback paths work properly now.
+- Scalers now use surface pitch instead of image width - this is
+  reported to solve many strange display problems in non-OpenGL mode
+  on Macs
+- Ending sequences may now be safely paused.
+- Added the rest of devel/ and users/ documentation into MSVC .dsp
+  files.
+- Control scheme upgraded.  Old versions of keys.cfg will no longer
+  work.
+- PNG transparency info (tRNS chunk) is now set properly, based on
+  info in the .ani files.
+- Paletted images should render much faster now, and collisions
+  between mods are less likely.
+- New font engine: fonts are loaded and treated as alpha-channel-only
+  images, with font effects handled as backing images.
+- Melee works properly with alpha-channel graphics new, even when
+  mipmapped.
+- Lander report drawing handled more sensibly now
+- Binary resource indexes have been replaced with textual ones.
+- All spritework is done internally in 32BPP.
+- Removed MikMod i/o hacks.
+- The temp files for representing star and group data are now kept in
+  memory instead.
+- Separate config_win.h file for build.sh builds on Windows
+- Lowered some animation rates to reasonable levels, lowering CPU
+  usage.
+- Changed comm subtitle caching scheme.  Should kill the "blue comm
+  screen" problem forever.
+- Refactored setup menu code to use generic widgets.
+- Cleaner build output. Set '$MAKE_VERBOSE' to 1 for old output.
+- Improved dependency tracking for unix build system. "./build.sh uqm
+  depend" is now only needed for checking for new source files.
+			     Version 0.4
+			    -------------
+- Savegame slot defaults to the last one used during this play
+- PC intro and ending sequence are now present
+- 3DO intro and ending movies are supported for those who have these
+  movies from the 3DO CD of Star Control II
+- Improved slave shield graphics
+- Added a new -l option to produce logfiles
+- Added a new 'triscan' scaler derived from scale2x
+- Made the fact that self-destructing ships grant resources more obvious
+- Added a "config dir" option for holding saves and melee information
+- Cocoa hooks
+- Setup menu now permits configuration of some options.  They do not
+  yet persist past program quit, though.
+- Added a "--version" option
+- Melee images are now based on the (richer) DOS content
+- 3-step melee zooming as per the PC version is now implemented
+- It is now possible to complete the game without ever allying with the
+  Starbase (if one is insane; this is known on the forum as "Beating The
+  Game Differently" - but bugs and plot elements preventing this have been
+  fixed or evaded under this circumstance).
+- Fixes to the Quit Confirmation dialog
+- Collisions/encounters with "invisible" fleeing ships gone
+- Other ships insystem remain in proper locations after planet landing
+- Fixed some keyboard "focus" problems where flight controls were
+  being cleared at inappropriate times, or interfering with menus

+- A game crash that manifested when pausing after 85 minutes has been
+  corrected
+- Main menu version number drawn more consistently
+- Transparency bugfixes - 3DO ending credits, planets in battle
+- Content packs may also be named ".uqm" - these are really still
+  zip files, but you can't expand them by accident.
+- One may now configure a joystick without crashing the game if the
+  joystick is not present
+- Music volume normalized throughout the game
+- Thread system completely reworked to provide more detailed thread
+  information, and to prevent resource leaks

+  basic structure now
