- fixed: clientside jumping power, jumping enabled
- fixed: player start spot selection (especially TNT/Plutonia)
- fixed: mobj Z coordinates were sometimes incorrect on clientside
- fixed: server didn't increase client's bandwidth rating, ever
- fixed: WAD warning box in Client Setup screen was in the wrong place
- fixed: halos weren't always displayed correctly on clientside

drD3D:
+ option -triple: enable triple buffering in fullscreen mode

XG:
- XG should always be disabled on clientside

jDoom:

Version 1.7.12
--------------
+ option -leaveramp: don't reset color settings back to previous values
  at shutdown
+ JWADs: IWAD supplements (uses normal WAD loading order)
+ Data\Graphics directory: Doomsday's graphics resources (UI textures)
+ cvars 'ui-cursor-width', 'ui-cursor-height': UI mouse cursor size
+ added new cvar controls to the Control Panel (e.g. multitex, HUD mirror)
* the first incarnation of the Doomsday UI theme, "Gradient", was 
  replaced with a much more polished theme, "Plastic"
* UI mouse cursor size and movement depend on display resolution
* music data will not be cached into the memory zone while loading 
  (large MP3s wasted a lot of space) 
* paths that contain the base path are normally printed without the base
- removed obsolete settings from Control Panel
- removed detail texture maximum distance cvar and Control Panel slider
- removed cvars 'rend-light-clip', 'rend-light-shrink'
- fixed: possible crash in Con_Error()

Definitions:
+ DED version 6: semicolons are optional (the default is 6)
+ added Defs/Doomsday.ded: include definitions shared by all games
+ 'Top map', 'Bottom map', 'Side map' added to Light defs and
  Decoration:Light defs (name of lightmap to use; empty means default,
  "-" is none)
+ particle types pt_modelNN: use 3D model ID = "ParticleNN" 
+ particle flags ptf_zeroyaw, ptf_zeropitch, ptf_rndyaw, ptf_rndpitch
+ 'Frame', 'End frame', 'Spin' added to Generator:Stage
+ up to 32 sky models can be defined in a Map Info definition
+ added an ID key to the Model definition
* flags can be defined using this syntax: Flags = flag1 | flag2 | flag3;
  (flag prefixes must be omitted)
* Defs/Doomsday.ded is always read first
* Flag definitions moved to Defs/Flags.ded
* XG definitions moved to Defs/XG.ded
* maximum number of submodels is now 8
* Map Info definitions can be copied
* 'InFine' is an alternative name for the 'Finale' definition

Network:
- fixed: server increased a client's bandwidth rating too rapidly

Sound:
* sounds from PWADs are not replaced with automatic external resources

Refresh:
+ named Model definitions (Model:ID), not assigned to any state
+ lightmap resources are read from the Data\x\LightMaps directory
+ texture/flat animation sequences defined using Group defs (Anim.ded)
+ "tgf_smooth": interpolate between steps in texture/flat animation
+ particle generator flag "gnf_group": triggered by all in the flat's
  animation group
+ particle generator flags "gnf_blendsub", "gnf_blendrsub": subtractive
  blending for particles
+ particle generator flags "gnf_blendmul", "gnf_blendimul": normal and
  inverse multiplicative blending for particles
+ option -nohighpat: disable high-resolution patches
* weapon model skins are precached
* texture/flat groups can be used purely for precaching
* detail texture contrast is preprocessed: there will be multiple 
  instances of the same texture with different contrast levels (needs
  a bit more memory but allows faster rendering)
* 8-bit particle textures are interpreted as pure alpha data
* PCX images aren't loaded redundantly from virtual files  
- fixed: PWAD test when loading highres flats and patches (-pwadtex)

+ cvar 'rend-dev-wireframe': render player view in wireframe mode
+ cvar 'rend-dev-freeze': stop updating rendering lists (for debugging)
* renderer uses multitexturing for detail textures, dynamic lights,
  interpolated texture animation and model shiny skins
* shiny skins are correctly masked by alpha in main skin
* plane glow on models is stronger than before
* if multitexturing is available, masked walls will get one dynamic 
  light (previously masked walls were not lit by dynlights)
* dynamic light polygons are no longer clipped
* calculations to determine surfaces affected by a dynamic light are
  more accurate (light has a better chance to be visible)
