Game changes between 0.1.7 and 0.1.8
 * Optimized some of the game drawing routines. This should help flicker on
   low-end systems.
 * You will receive a message of insufficient resources when you try to build
   something you cannot support.
 * Added `cheat code' message strings. Really meant for debugging though.
 * The Painter can now construct Basic huts, just like normal cavemen.
 * The Caveman can now construct all three types of hut: Basic, Medicine and
   Woodcraft hut.
 * The Caveman can now dig a new Cave.
 * The test map no longer starts with a complete base - you have to build it up.
 * Medicine man tech support decreased (was 3, now 2).
 * Medicine man food cost reduced (was 2, now 1).
 * The Caveman now offers tech support (1)
 * Painter upgrade time decreased slightly.
 * Medicine man upgrade time decreased slightly.
 * Hut and cave build queues removed (temporarily).
 * The game should now build correctly on any flavour of UNIX Allegro runs on
   (not really a game change, but what the hell).
 * Many changes to the game's internal code and scripting language.

Bug fixes
 * The game no longer crashes when changing fog-of-war drawing options without
   starting a campaign first.
 * Fixed a bug when the mouse was over the side of the map with the structure
   mask active.

Known issues
 * The fog-of-war state isn't always correct.
 * The building location selector is not removed when the group leader is
   removed from the group (killed, or enters a structure).
 * You cannot upgrade a unit if you don't have enough supply to build a new one,
   even if you wouldn't exceed you supply limit by upgrading this unit.
 * The minimap blanks out when the fog-of-war drawing mode is changed.



Game changes between 0.1.6 and 0.1.7
 * 8 bit colour mode now works, but team colours aren't adjusted.
 * Audio controls under the Options menu.
 * New structure: the Cave. It serves as a warehouse, command centre and
   residential structure.
 * Functioning minimap, including command targeting.
 * You can now click on unit portraits to select and deselect them.
 * Units now move to a nearby location if the target cannot be reached.
 * Structures are now actually build instead of simply dumped on the map.
 * Command queueing now works, and so does the progress indicator.
 * Some of the campaigns have been renamed.
 * Pressing ## quickly now centres the map on the specified group.
 * Hardware acceleration will now be used if it's available.
 * A sound is played when a button is clicked.
 * The Modern and Future campaigns have been removed and will be replaced by
   something else eventually.
 * A red/green grid now appears over the map when you issue a build command.
 * The game will run from any directory, as long as it can find a config file
   that tells it where to find its datafiles.

Bug fixes
 * Canceling a build command no longer crashes the game.
 * Giving a build command to a group leader no longer sends the whole group
   to the target location.
 * Fixed a bug with overlap detection at the edge of the viewport.
 * Fixed a crash bug when not all units in the group understand a certain
   command.
 * Fixed a silly bug that caused the game to ignore the specified midi-volume.
 * Fixed a bug with overlap detection between a unit and a structure where
   the order was determined by wether one or the other was selected.
 * Several spelling errors were fixed.

Known issues
 * The transition between the fog-of-war and the black mask has a perfectly
   transparent border when using gouraud shading.



Game changes between 0.1.3 and 0.1.6
 * Game now runs under DOS, Windows and Linux!
 * The fog-of-war now has a bitmapped option in addition to shading.
 * The game now has a menu button and an options screen.
 * The framerate was increased dramatically.
 * Movement code now uses A* instead of the silly algorithm I started with.
 * A (barely) functioning command panel was added.

Bug fixes
 * The fog-of-war no longer shrouds the entire map from time to time.
 * Upgrade commands no longer apply to all selected units.
 * Fixed a bug where the map code tried to scroll of the map, resulting in a
   crash.
 * Fixed crashes related to the screen update method and unit overlap.
 * Fixed crashes related to merging/splitting of unit lists.

Known issues
 * Units and structures aren't always drawn in the correct order when updating
   the screen.
 * The game crashes when started in 8bpp mode.
 * The A* code isn't entirely full proof and can sometimes hang the game for
   about a second.
