• Fixed: The program crashed when toggling fullscreen mode twice while a menu was active
• Fixed: When picking up a laser or super laser, the new laser level shown in the HUD message was one too low

• Improved: Joystick deadzone handling is a numerically more precise
• New: Added the command line switches -movies (inverse to -nomovies) and -briefings (inverse to -noscreens)
• New: Colored segment rendering can now be suppressed via the mission configuration (-colored_segments 0|1)

  v1.15.311:
• Fixed: With advanced collision handling, flying through powerups briefly accelerated the player ship
• Changed: No multithreading will be available in the standard D2X-XL application (d2x-xl.exe)
• Improved: Made the networking code more robust
  v1.15.310:

• Fixed: When not in a game, changing the player ship type in the gameplay menu had no effect
  v1.15.309:
• Fixed: Robots didn´t fire and could hardly be hit anymore
• Fixed: Players could pick up powerups behind impassable walls (e.g. gratings) if the powerups were sticking out of the segment a bit
  v1.15.308:

  v1.15.300:
• Fixed: Sounds from behind closed doors were audible
• Fixed: Marker weren´t rendered with their number in the automap

• Fixed: When the player ship was changed inside the mission, the player spawned in the previously chosen ship when respawning after having been destroyed
• Improved: Players cannot pick up energy boosts used for marking a path
• Improved: Path finding used for sound handling is much, much faster now (this had shown to be a major performance hog before)
• Improved: Sound from a segment with more than one sound source will not be overly loud anymore
• Improved: The range of the Guidebot has been increased from 200 to 1000 segments from its current position, making it more likely that it will find stuff for you in huge missions like e.g. Anthology
• New: Players can have a path to an arbitrary path marked with the new ´minotaur´ cheat
  v1.15.299:
• Changed: During lightmap calculation lights will also contribute to faces hidden behind walls that may disappear or become transparent when playing the level

  v1.15.294:
• Fixed: Robots that died with a death roll kept rolling (instead of exploding) as long as they were hit
• Fixed: When particle effects were turned off, the amount of debris couldn´t be changed anymore because the corresponding effects menu entry got hidden
• Fixed: Even if effects were disabled, extra debris was created during explosions
• Improved: Explosions from destroyed robots will now move towards the player while they are visible, giving a more realistic explosion effect
  v1.15.293:
• Fixed: The program crashed when invoking certain menus (e.g. the keyboard configuration) when using localized messages (hint: Install the latest d2x-xl data package)
  v1.15.292:
• Improved: Loading screens shuffling is now more random
  v1.15.291:
• Fixed: Colored segments still weren´t always rendered right
• Improved: Descent 2 custom background images will now be shuffled for missions that have no custom background images
  v1.15.290:
• Fixed: D2X-XL crashed when a destroyed robot dropped items not available in D2X-XL (due to errors in the mission)
  v1.15.289:
• Fixed: Rendering colored segments (water, lava) didn´t work right anymore
• Fixed: Re-enabled some code to unstick objects, so player ships (hopefully) won´t get stuck in robots anymore when colliding with them
  v1.15.288:
• Fixed: When enabling custom weapons and playing a level that has some, then leaving the level, disabling custom weapons, and playing the same level again, custom weapons were still enabled
• Changed: The option that makes gatling guns start to fire with a delay has been moved from the sound to the gameplay options menu. When this option is enabled, gatling gun fire will be delayed even if the gatling rotation sound is turned off or not available; in that case you will just not have an audio feedback for that like you have when the spinning sound is there.
• New: The new game menu now also has an option to disable custom weapons
  v1.15.287:
• Fixed: Some areas in rendered movies were rendered black instead of white
  v1.15.286:
• Fixed: The credit screen´s background image wasn´t rendered properly
• Fixed: You couldn´t enable mods in the new game menu anymore
• Fixed: The last custom background used while playing a mission was kept for the main menu after playing
  v1.15.285:
• Fixed: When particle collision handling was enabled, the program could hang or crash
  v1.15.284:
• New: You can now disable custom weapon mods via the gameplay options and more multiplayer options menus
  v1.15.283:
• Fixed: Players frequently couldn´t fire shots and/or couldn´t be hit in multiplayer games (usually this went away when closing the multiplayer session and starting a new one without terminating the program)
• Changed: D2X-XL will not override custom weapon info (from custom HAM files) for multiplayer games by resetting weapon info to the Descent 1/2 default values anymore
  v1.15.282:
• Fixed: With lightmap based lighting levels were completely bright
  v1.15.281:
• Fixed: Levels containing pre-computed colored light (from DLE-XP) were rendered pitch black when the lighting method was set to ´basic´
  v1.15.280:
• Fixed: When shadows were enabled, firing flares or transparent shots (lasers etc.) led to all kinds of rendering flaws
  v1.15.279:
• Fixed: When moving diagonally into a wall, the ship often briefly hung or stopped instead of smoothly sliding along the wall
  v1.15.278:
• Fixed: When firing Gatling shots into a skybox while effects were enabled (and thus light tracers were rendered), the mine walls disappeared due to being overlapped by the skybox and (semi-) transparent faces (e.g. gratings)
  v1.15.277:
• Fixed: Sometimes objects were rendered that weren´t visible to the viewer
• Fixed: ´repair center´ segments from standard levels will be converted to regular (non-functional) segments when reading them. This fixes a flaw in standard level format where segments could be marked as ´repair center´ although repair centers weren´t supported by standard Descent and prevents this flaw from being exploited by using D2X-XL in multiplayer games where some participants are using other Descent versions
  v1.15.276:
• Fixed: When taking a lot of screenshots, the program encountered a severe error due to a memory leak, throwing the player back to the main menu
  v1.15.275:
• Changed: At highest render quality, glow will be applied to the textured automap, too
• Improved: When the HUD is turned off, automap screen shots will not show keyboard control information
  v1.15.274:
• Changed: Screenshots will now show the D2X-XL label and Descent web site URL in their lower right corner
  v1.15.273:
• Fixed: The rear view stayed black when shadows were enabled
  v1.15.272:
• Fixed: When finishing the Descent 1 campaign, the start instead of the end briefing was displayed
• Fixed: The program could crash when the level was changed after the player had died
• Fixed: When dieing in a Descent 1 secret level after having destroyed the reactor, the program tried to put the player in a wrong level or even crashed
  v1.15.271:
• Fixed: The game could crash when loading a level with mesh improvement quality set to high
• Fixed: The pathfinding wasn´t properly reconfigured when entering or leaving secret levels, which could cause program crashes
