Fixed bugs

Crash when locating a fallback skin for a model without skins (out of bounds memory access).
Crash when replacing text definitions (null pointer access).
Crashes with add-ons using the HI_START/HI_END method of texture replacement.
Fatal error attempting to enter lighting debug mode (rend-tex 2).

Platform-specific

Unix: All Games: chat messages don’t show in HUD due to improper use of memory buffers. 1092
Mac OS X: launcher config updated for ringzero: all game plugins’ resources made available using vdmaps.
Windows: crash when switching to desktop resolution at shutdown (a late window resize callback occurred).

Don’t override user’s monitor color transfer function (all changes should be applied relative to the user’s transfer func).
All Games: centering the map title in a wide viewport (when entering a new map).
Incorrect world dimensions of sprites with high-resolution texture replacements.
Broken “tall patch” composition.
Out-of-namespace flat/patch resource lookup errors.
Sky models and various map properties invalid after an engine reset.

Server: connecting to one’s own local dedicated server shouldn’t cause a duplicate client ID error.

listmaps printed [null] as the source file for missing maps and omitted maps outside the default progression.

The application data path now has priority over system-wide paths (e.g., those set with doomwaddir).
Improved startup performance with several file system and resource management optimizations.
Tools (texc, wadtool, md2tool) are included in the main distribution packages (unless CONFIG+=deng_notools).
Added the deng_tests build option: additional small test apps will be built and deployed alongside the engine binaries.
Moved engine sources to domain-specific subfolders, clarifying the internal structure and dependencies.
Moved common, generic-purpose code from engine to libdeng1/libdeng2.
Launcher: removed “j” prefixed game plugin names to “lib” (or none).
Launcher: removed options for configuring the display resolution (now offered in the engine itself).

The default display mode is fullscreen with desktop resolution on Windows and Mac OS X, maximized window for Unix.
Windows: doomsday.out is by default placed to AppData\Local\Deng Team\Doomsday Engine.
Windows: deng2 version metadata contains build number as part of version number.
Unix: defaults config file for de::UnixInfo.

FMOD: Attempt to detect system's speaker mode and use it (5.1, 7.1, Prologic).
FMOD: Added command line options for setting speaker mode manually: speaker51, speaker71, speakerprologic.
FMOD: sound-rate has no effect with FMOD because upsampling is not needed, FMOD can resample when necessary.
FluidSynth (Unix): compiling with the system libfluidsynth, uses libfluidsynth’s output driver to play music
FluidSynth (Unix): audio driver can be chosen with “fluidsynth:driver” in the defaults info file.

Renamed core resource packages (e.g., jdoom.pk3) using the new “lib” prefix instead of “j” (libdoom.pk3).
Removed “j” prefixed game plugin version metadata.
Dropped old j-plugin version numbers, now using the main Doomsday version.

Imported script engine from Hawthorn (presently only used for libdeng2 config and storing automatic update preferences, main window position, display mode settings).
Added loglevel to set the log entry level (e.g., DEBUG or TRACE).
Each v/verbose increases the enabled log entry level by one.
More compact log output: abbreviated log entry headers.
Script: references between Records can be restored after deserialization (with some caveats).
Script: improved textual representation of record.
Script: boolean numbers are printed as “True” and “False” instead of “1” and “0”.
Script: added “export” statement and keyword.
Script: calling native functions from scripts.
Script: native modules DisplayMode and Version.
Replaced deng.de script ⇒ Config.de, added functions for resetting to/accessing the default config values.
Added package persist.pack for storing all persistent state into.
Config stored persistently in /home/persist.pack/modules/Config instead of /home/deng.config.
Serialization versioning.
