This article lists the important changes in [[version:doomsday_version_1.12]].


====== Fixed bugs ======


{{:twocolumn|


===== Resources =====


  *  Fatal error playing **Icarus: Alien Vanguard** MAP16, due to an oversight in the line-of-sight algorithm when dealing with maps with overlapped lines.
  *  Fatal error playing **Astrostein** when firing the "BFG", due to misinterpretation of truncated Patch format images.
  *  Fatal error playing **Eternal Doom** MAP10, due to mishandling of overlapped sectors in the BSP builder.
  *  **BSP Builder:** Partitioner logic error which incorrectly attributed sectors to BSP leafs around id Tech 1 map hacks (holes in the floor, incorrect lighting, ...).
  *  **BSP Builder:** Failed partitioning a map with overlapped single-sided lines.


===== {{tag|Renderer}} =====


  *  Light decorations disappear instantly at distance.
  *  Malfunctioning secondary lens flare dimming.
  *  Font selection of the thinker indices debug visual.
|


===== {{tag|UI}} =====


  *  Display mode changes no longer cause the game window's input focus to be lost, which would pause the game.


===== Gameplay =====


  *  **Doom:** Icon of Sin explosions deal no damage/spawned at incorrect height.
  *  **Doom:** Behavior of sector type 10 "close in 30 seconds" (return to original height).
  *  **Hexen:** Player spawning under 3D bridge object failed.
  *  **XG**: Erroneous attempt to allocate dummy map line sides via DMU.


===== {{tag|Hexen}} =====


  *  The default value of {{:var|msg-echo}} was corrected to 1.

====== New features and changes ======


{{:twocolumn|


===== {{tag|UI}} =====


  *  Performance improvements and bug fixes in the UI framework.
  *  Introduced an abstract data model to allow data to be used more flexibly with several instances or types of widget.
  *  New widget: on/off toggle. It is now used in various places to modify the values of script variables and cvars.
  *  New widget: choice. Allows selecting one item from a collection of items.
  *  New widget: slider. Picks a numerical value within a range.
  *  New widget: dialog. Modal or non-modal popup for presenting information or making choices.
  *  Replaced old busy mode indicator screen with a BusyWidget. This allows using the same UI element elsewhere, e.g., in the update download dialog.
  *  Background tasks (multithreading) is now taken advantage of when processing text for drawing in the UI framework. Also improved wrapping of text using tab stops.
  *  Added an About dialog that displays information about the installed version of the engine and current GL and audio configurations.
  *  Added new settings dialogs for video, color, audio, input and updater settings.
  *  Several settings for advanced/developer use (ID indicators, special texturing modes, etc.) are now easily accessible via the "gauge" popups in the renderer and audio settings dialogs.
  *  Settings can be reset to defaults by group.
  *  The old [[:control_panel]] was removed.
  *  Added a GUI editor for the renderer's appearance settings. The editor opens in a sidebar next to the game view.
  *  Renderer appearance profiles: choose from the set of built-in profiles or customize your own. Profiles work independently of the loaded game plugin.
  *  When opening the log for the first time, don't waste time scrolling through all the messages since launch.
  *  **Windows:** [[http://www.google.com/fonts/specimen/Open+Sans|Open Sans]] is used as the UI font.


===== {{tag|Console}} =====


  *  When the [[:task_bar]] is dismissed, the current contents of the console command line are saved in the command history.
  *  [[:console]] command line autocompletion (when pressing the Tab key) shows a popup with all the possible completions. Console variables are listed with current values and commands with a brief description.
  *  Adjusted autocompletion behavior: the popup will only open if there is nothing unambiguous to add to the command line.
  *  Key modifiers can be used for word jumping.
  *  The command line can be toggled into [[:doomsday_script]] mode.
  *  Added the command {{:cmd|rendedit}} to open the Renderer Appearance editor sidebar.
  *  Improved the command {{:cmd|help}} to list autocompletion and log navigation shortcuts (with platform appropriate Unicode characters).


===== Developer =====


  *  Upgraded to Qt 4.8.5.

|


===== {{tag|Updater}} =====


  *  Redesigned automatic updater's UI using Doomsday's own UI framework.
  *  Update notifications do not force a switch to windowed mode any more.
  *  Option to download updates automatically when they become available.


===== {{tag|Input}} =====


  *  Input Settings: by default the sensitivities of the X and Y axes are linked together so one doesn't have to carefully make sure both are the same.


===== {{tag|Audio}} =====


  *  Use sector cluster granularity for environmental audio. Sectors comprised of multiple disjoint geometry groups now use independent environmental audio characteristics.
  *  Deferred calculation of environmental audio characteristics until necessary. The BSP leaf blockmap is used to accelerate the task.


===== {{tag|Renderer}} =====


  *  Built-in appearance profiles: Vanilla, Defaults, and Amplified.
  *  In widescreen views, the FOV angle is now less dependent on the view width. This allows using the same FOV angle with both traditional 4:3 and widescreen views.
  *  Added BSP leaf clustering for the support of id Tech 1 map hacks. Revised map geometry generation and dynamic lighting to work at cluster level using the half-edge data structure.
  *  Added sector plane mapping and separate physical/visual planes for clusters. Used in the support of id Tech 1 map hacks.
  *  Batched surface redecoration by material and addressed associated performance bottlenecks.
  *  Deferred initialization of Bias lighting data until necessary and improved deallocation mechanism for faster shutdown. Also, significantly reduced memory requirements through reformatting.
  *  Bias light sources in the void are dynamically occluded.
  *  Added cvar {{:var|rend-dev-sector-show-indices}}, enable drawing of sector indices for visual BSP builder debugging.


===== {{tag|Server}} =====


  *  Further streamlined map data elements, removing unused functionality and reducing memory requirements.


===== {{tag|Shell}} =====


  *  Console: Pressing Tab will print a list of possible completions for the current word.


===== Scripting =====


  *  Added [[:appconfig.de]]: configuration for the application. Imported by [[:config_module]]. The client-specific configuration variables were moved to the new script.


===== {{tag|All Games}} =====


  *  Added cvar {{:var|map-title-position}} for controlling if the map title is positioned at the top or bottom of the view when the automap is open.
  *  Position the message log below map title when visible.


===== {{tag|Doom}} =====


  *  Added cvar {{:var|game-objects-gibcrushednonbleeders}} for controlling whether only bleeding mobjs should be gibbed (a Doom bug fix).
