===== 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.

|

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

• 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.

• The default value of msg-echo was corrected to 1.

===== {{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: Open Sans is used as the UI font.

• 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 rendedit to open the Renderer Appearance editor sidebar.
• Improved the command help to list autocompletion and log navigation shortcuts (with platform appropriate Unicode characters).

• Upgraded to Qt 4.8.5.

• 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.

• 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.

• 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.

• 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 rend-dev-sector-show-indices, enable drawing of sector indices for visual BSP builder debugging.

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

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

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

• Added cvar 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.

• Added cvar game-objects-gibcrushednonbleeders for controlling whether only bleeding mobjs should be gibbed (a Doom bug fix).
