ZDBSP has received a small bug fix and is now at version 1.18.1. This corrects a problem in earlier versions that could potentially create invalid nodes with maps that have more than 65535 lines or with maps that use the new node format introduced in ZDBSP 1.18.

ZDBSP 1.18 is now available. This version introduces a new node format for better compatibility with UDMF maps that have vertices with fractional coordinates.

ACC 1.53 is now available and supports the latest features of ZDoom 2.6, such as scripts with four parameters, waiting on named scripts, and some very minor bug fixes.

In addition, the -h command line option no longer silently promotes non-Hexen features to the ZDoom script format. You now get an error when you try to use ZDoom-features in Hexen-compatible mode.

I would have put this up with ZDoom 2.6.0, but it slipped my mind. Sorry about that.

ZDoom 2.6.1 is now available. This is primarily a bugfix release for 2.6.0, however it contains one breaking change: Voxels are now rotated 90 degrees to match their orientation in Slab6.

There are also a few minor new features:

• DECORATE:
  
  • INVENTORY.RESTRICTABSOLUTELY flag for being extremely restrictive of cross-class item pickup
  • PLAYERPAWN.CANSUPERMORPH flag for morphed player classes that give you a Tome of Power powerup if you an attempt is made to morph you into the same class while you are already morphed into it. (Used by Heretic's chicken)
• MAPINFO:
  
  • RandomPlayerStarts will disable voodoo dolls and instead spawn players at random start spots.
  • UsePlayerStartZ will respect the start spots' Z coordinates and let you spawn players off the floor.
• Hacx 2.0 is now a detectable IWAD.

ZDoom 2.6.0 is now available, almost two years after version 2.5.0 was released. This release is available in the usual Windows version as well as in a Mac OS X version.

There have been hundreds of bugs fixed since then as well as numerous enhancements:

• Added Hacx IWAD support.
• Added text-format Strife conversation system with USDF and ZSDF.
• A textured automap is now available; automap graphics are now externalized.
• Rewritten menu system, which can now be defined with the MENUDEF lump.
• Externalized intermissions to MAPINFO.
• Externalized IWAD detection and gave each IWAD its own independent config section.
• Added FluidSynth and GUS emulator softsynths; fixed issues with TiMidity++.
• Added VOC support and enhanced MIDI playback with support for alternative formats such as XMI and HMI.
• Action specials: Added Ceiling_LowerAndCrushDist and Thing_SetConversation. Added console command to execute specials.
• ACS:
  • Increased maximum script number from 999 to 32767.
  • Named scripts allow to avoid script number conflicts altogether.
  • Added StrCopy, CheckSight, SetActivator, SetPointer functions.
  • Added APROP_ScaleX/Y and APROP_Mass actor properties.
  • Added temporary dynamic strings variables with StrParam.
  • Scripts can now have up to four parameters.
• DECORATE:
  • Added A_CheckFlag, A_FaceMaster, A_FaceTracer, A_RadiusGive, A_SetMass, A_SetScale, A_Warp and A_WolfAttack...
  • Enhanced A_AlertMonsters, A_BFGSpray, A_Blast, A_CustomBulletAttack, A_FireBullets, A_GunFlash, A_PainAttack, A_RadiusThrust...
  • Added an actor pointer manipulation system with several new codepointers...
  • Added DOHARMSPECIES, DONTCORPSE, SEEINVISIBLE and INVENTORY.UNTOSSABLE
  • Increased damage type flexibility in several ways with DeathType and PainType.
  • Added customizable fléchettes.
  • Made accuracy and stamina accessible through DECORATE expressions.
  • Added ProjectileKickback, Inventory.RestrictedTo and Inventory.ForbiddenTo class-based properties.
  • Backported VisibleToTeam, VisibleToPlayerClass and weapon DropItem feature from Skulltag, and enhanced them.
  • Added "Fast" keyword for states and deprecated the unreliable FASTER and FASTMELEE flags.
• Added a secret hint system.
• 3D floors support.
• FraggleScript support.
• Voxel support.
• SBARINFO: Ammo 1/2 capacities added to DrawNumber, support for color names in colored text.
• SNDINFO: Added musicalias and attenuation.
• Compatibility: fixed issues with Eternal Doom, Happy Time Circus, Phobos, vanilla compat, Boom compat, light levels higher than 255, Heretic, Strife, MUSINFO, misnamed UDMF field.
• Fixed loading of BMF palettes.
• restart console command.
• Added PALVERS lump for specifying alternate graphics to use with a paletted render, in case the graphics you really want to use look bad without true color.
• Custom IWADs no longer need to include a COLORMAP, as ZDoom will generate one automatically if it is missing.
• Fixed vertical tiling of non-power-of-two textures.

(Big thanks to Gez for compiling this list of changes.)

ZDBSP 1.17 has been released. This version fixes a critical bug introduced in 1.16 that caused it to write garbage for normal nodes. Upgrading is strongly recommended.

It also has some minor performance improvements.

ZDoom 2.5.0 has been released.

The primary motivation for this release was the new vastly improved polyobject support. To recap, polyobjects in Hexen and previous versions of ZDoom had to obey these restrictions:

• They had to be simple, convex objects.
• They could not leave the subsector they were spawned in.
• You could not have more than one polyobject per subsector.

None of these restrictions apply anymore:

• Polyobjects can be any crazy shape you want.
• Polyobjects can move anywhere on the map without restriction.
• You can have as many polyobjects in a subsector as you want. You can even have polyobjects inside polyobjects if you feel like it!
• You can also have a polyobject cover as many subsectors as you want.

There are some other improvements as well, including:

• Support for uncompressed extended nodes, also supported by Eternity Engine and PrBoom+, to create a new cross-port standard for node storage.
• Support for using Byte Map Fonts.
• Ability to use metadata tags in audio formats to define custom loop points.
• Added support for the MUSINFO lump (from Risen3D and PrBoom+).
• Improved compatibility settings to optionally allow a greater faithfulness to the vanilla Doom and vanilla Heretic.
• ZMAPINFO as an alias for MAPINFO to avoid compatibility problems with other ports parsing this lump.
• Full rewrite of the SBARINFO system allowing many additional features and options.
• Added support for multi-monitor display.
• Buddha mode (one undestructable hitpoint)
• Default reverb environment setting in MAPINFO
• Several generalized codepointers to emulate some very specific Heretic and Hexen action functions
• Enhanced poison damage system
• Generalized railgun codepointers
• New automap options
• HOM detection system
• ...and more

There were some bugs fixed in there, too.

ACC, the script compiler for ACS, has been updated to version 1.50. This version fixes a bug when partially initializing multidimensional arrays.

ZDBSP has been updated to version 1.16.

This version can correctly write nodes for maps that have more than 65536 vertices after node building. Thanks to entryway for producing a test map.

ZDBSP has been updated to version 1.15. This version adds support for uncompressed extended nodes for prBoom+.
