******************************************************************************
                            VERSION 1.17
******************************************************************************

04.04.2005
  Fixed DeHackEd support.
  Fixed reseting of velocity after teleport in Hexen.
19.04.2005
  Fixed crash with stairs.
  Fixed removal of wings in Heretic.
  Fixed some Strife cheats.
  Several fixes by someone - fixes freeze in OpenAL driver on Linux, better
 support for UTF-8 console for end text.
25.04.2005
  Started work on autoconf generated configure script.
26.04.2005
  I installed gcc 4.0.0 and it now warns about classes having virtual functions
 but no virtual destructor.
  Already usable configure script with system detection.
  Temporary fix in vcc when compiled with optimisations, fixed warnings.
27.04.2005
  Fixed most of the compiler warnings.
  All configurable stuff is now in configure. Added CD driver detection.
28.04.2005
  Added automatic detection of Allegro or SDL.
  Started work on updating MD2 models. Created Makefile for fixmd2 and added it
 to build process. Had to increase maximal vertex count, mostly because mm3d
 doesn't merge ST vertexes.
29.04.2005
  Continued to update MD2 models.
30.04.2005
  Continued to update MD2 models. Lost soul's animated fire animation was real
 pain. I need a better way to do this.
01.05.2005
  Continued to update MD2 models. Added support for specifying a skin index.
 This allowed me to make a very easy torch fire animation. Must update lost
 soul, burning barrel and maybe other models to take advantage of this. This
 will also make very easy to add support for damaged skins.
02.05.2005
  Updated animdefs script to support range animations and to recognise other
 ZDooom specific keywords. Added support for BOOM's animated lump. Moved switch
 list to r_tex, since they will be defined by animdefs.
03.05.2005
  Started a work on texture classes. For each texture format there will be a
 class that supports it. This will make drivers completely independent from
 formats. I started by creating a texture list. Texture class currently has
 type and index of corresponding type texture. Wall and flat textures now use
 index in new texture list, drivers doesn't have arrays for flat data anymore.
  To names list added adding of names, that should be lowercased and no longer
 than 8 characters. This will be used by texture list and wad files.
04.05.2005
  Some fixed by Firebrand.
  Added to texture list sprites and skybox textures. In OpenGL and Direct3D
 drivers removed inversed width and height arrays. Fixed possible bug with sky
 box textures.
05.05.2005
  Made cnter messages to be drawn much lower and to drawn with wrapping in a
 case of a long messages.
  Added skins and 2D images to texture list. Since these are added dynamicly,
 I had to add a function to drivers that updates driver's texture data lists.
 Lists of all registered skins now is in r_tex. And both of them doesn't have
 limitations anymore.
06.05.2005
  Removed SetFlat from all drivers since SetTexture can detect if it's a flat.
 Removed textureheight array since it can be easely calculated. Changed texture
 animation to one common array.
07.05.2005
  Added width, height and offset texture properties. Also added wall patches to
 the texture list. Created classes for different texture formats.
  Changed OpenGL and Direct3D drivers to load textures as 8 bit and convert
 when uploading.
08.05.2005
  To all texture classes added function Getpixels that loads the texture. After
 this all drivers became independent from texture formats. Some functions that
 generates texture can be merged into one. All of the properties of different
 texture types now are in texture classes, old lists were removed, with this
 the TypeIndex property. Also added function GetHighResPixels that, depending
 on usage type loads high-resolution version.
  For front sky layers of double-skies now there's a flag intexture.
10.05.2005
  Added DriverData to textures where drivers can keep driver specific data.
  Added texture data format attribute, which can be 8-bit, 8-bit with custom
 palette or true-color. Loading of skins and sky box texture use texture API.
 Textures now have a GetPalette function that returns the palette of texture.
 Moved texture animation to texture class.
  Finally installed TiMidity patched for SDL_mixer. And it turned out that
 conversion of MUS to MIDI didn't produce a valid MIDI file. After replacing it
 with original qmus2mid I got working MIDI music.
11.05.2005
  Added function GetPixels8 to texture class that converts texture to 8-bit if
 texture is in another format. It's primarily for software renderer, but there
 may be other uses if it. Moved PalNum from texture base class to subclasses
 that needs it. Some oteher fixes if texture loading.
14.05.2005
  Changed multiple palettes array to a single main palette. Removed support for
 custom palette from patch texture since it's needed only by Heretic episode 2
 fnale pic which is a raw image.
  Added support for overloaded textures.
15.05.2005
  In OpenGL and Direct3D all textures now have mipmaps.
  Added remapping of color 0 for file textures.
17.05.2005
  Created texture manager class. Added a function for simpler iteration of a
 wad file lumps in fixed namespace, used to init sprites and flats. All texture
 functions moved to texture manager class.
18.05.2005
  Moved texture list to texture manager class.
  Added function to read a part of a wad file lump, will be used by texture
 type detection code.
29.05.2005
  Fixed bug with moving 3D floors.

  In compiler started to make types to be single class that contains all info
 and the rest of compiler to use types as objects instead of the pointers.
18.02.2006
  Finished changing compiler type handling. We don't have support for multi
 dimensional arrays, but that's a small price to pay.
19.02.2006
  Made true and false keywords.
  Implemented delegates. As a test made main Doom menu use them.
  Moved some special enums to classes.

 type.
13.03.2006
  Implemented support for private, read-only and transient fields.
  Removed asm version of progs interpreter. It wasn't used in last release and
 since there's gonna be many changes there, it would be very big hastle to do
 all of the changes there. Also using gcc's jump table feature C++ code should
 be fast enough.
  In VavoomC local variables are now initialised to 0.
15.03.2006
  Optimised savegame size by saving only used names and non-empty entries in
 server baseline. Also ACS data is saved more efficient.

 wrappers around set and get methods.
13.01.2007
  In view entity class I changed reference to the player object to be reference
 to the entity.
  Today I started to work on adding dehacked support to the engine. As a first
 step I moved all actor state methods to the Actor class. After that I merged
 remaining stuff from HackedActor class to actor class that allowed me to get
 rid of HackedActor class. Similarly moved weapon state methods to Weapon class
 and got rid of HackedWeapon class.
14.01.2007
  In progs I added a string replace method.
  I changed view entity to be a Thinker and then an Entity. After that I moved
 Owner field to Entity class and I could get rid of ViewEntity class. Then I
 changed Weapon classes to be inherited from Actor class. After that I could
 move weapon state action methods to Actor class. With this dehacked progs have
 just a single copy of states.
  I also implemented a more generalised way of making Doom demons faster in
 nightmare mode.
  Then I added dehacked parser to the engine. Currently it just parses patches
 and does nothing else.
  I also fixed angle based clipping to add polyobject segs of a subsector.
15.01.2007
  I implemented dehacked string replacements in engine.
16.01.2007
  In Doom progs I removed some of the abstract Actor classes. To simplify
 implementation of dehacked parser in engine I need to make progs to be similar
 to the dehacked progs. This means that I had to move all states to Actor class.
 After that I could implement handling of dehacked changes of states in engine.
17.01.2007
  Today I finished implementing dehacked changes of states, implemented changes
 of ammo counts, weapons, misceleanous values and started on things.
18.01.2007
  Today I finished implementing dehacked parser in engine. I removed makeinfo
 utility.
21.01.2007
  I started moving of info tables that dehacked parser uses to a dehinfo.txt
 script file.
22.01.2007
  I started moving states of Doom actors back to their classes. This required
 some changes in order to make it work over the network.
23.01.2007
  I finished moving states of Doom actors back to their classes.
  In dehinfo script I added original thing heights that are set when using a
 dehacked patch.
  I also fixed missing cleaning of active sequences list.
25.01.2007
  I implemented support for Dehacked patch support extensions for specifying
 flags with names and for strings block.
26.01.2007
  I changed sprite names internally to be in lower case.
  Then I implemented support for Dehacked patch extensions for code pointer and
 par time blocks.
  I also fixed rendering of mid-textures with an offset.
28.01.2007
  I moved Doom state action methods back to their classes.
  I removed limit on static lights.
  I created render data class. I moved most of the surface and sky rendering
 methods to this class.
29.01.2007
  I added pointer to the render data class to the level class.
  I moved light rendering methods to render data class.
01.02.2007
  I moved line tracing method from level info class to the engine.
  I created a method to serialise global ACS data, made global ACS data static.
03.02.2007
  I merged line tracing methods into a one that's in the level class.
04.02.2007
  I did some tests with rendering server and previous client level.
05.02.2007
  I fixed a crash in line tracing method.
07.02.2007
  In model definition files I added support for defining model skins.
  Firebrand added fixes from Boom to keep monsters stuck in the doors.
  I changed Actor classes in all games to have the same default values.
09.02.2007
  I created a class with ACS per-level data.
10.02.1007
  In level class I added pointer to the per-level ACS data class. I implemented
 support for suspending and terminating scripts in other maps.
11.02.2007
  I moved ACS native methods to the Level class.
13.02.2007
  I implemented propper support for execute always ACS scripts.
  I created a class for global ACS data.
  I started to implement support for terrain script.
15.02.2007
  I finished implementing support for tarrain script.
16.02.2007
  I did some cleanup after implementing terrain script.
18.02.2007
  I created a WorldInfo class that exists during the whole game session. I added
 pointer to the global ACS data class to this class.
19.02.2007
  I moved serialisation of ACS state to Level and WorldInfo classes.
22.02.2007
  I added references to LevelInfo and WorldInfo to Level class.
  I implemented support for LOADACS script.
26.02.2007
  I created an EntityChannel class. Currently it doesn't do anything yet.
27.02.2007
  I started to implement updates of some of the Entity fields using the
 EntityChannel class. In compiler I added a keyword that allows me to specify
 which fields to update.
28.02.2007
  In compiler I changed the way net fields are specified making it to be more
 like UnrealScript. I moved some methods that are used for network replication
 to Field class. In Entity class I added network role fields.
01.03.2007
  I created a PlayerChannel class that does updates of player fields similar
 to the way entity fields are updated. All player stats are now updated using
 PlayerChannel. I moved channels to the PlayerNetInfo class.
02.03.2007
  I changed some of the fields in BasePlayer class to be updated using channel.
03.03.2007
  I implemented support for conditional field replication.
04.03.2007
  I moved handling of dynamic lights and particles to LevelRenderData class.
05.03.2007
  I finished moving dynamic lights to LevelRenderData class.
06.03.2007
  I created a ViewClipper class and moved methods for angle based view clipping
 to this class.
07.03.2007
  I decided to move level rendering methods to LevelRenderData class and to make
 it more clear I renamed it to RenderLevel. RenderLevel class pointer is now
 passed to Drawer class to avoid usage of global variables. I also split all
 definitions of texture loader classes into a separate header file.
08.03.2007
  I added a Destroy method to the Thinker class that replaces old style method
 RemoveSpecialThinker and Entity's Remove method. I also merged create Thinker
 and Entity methods.
09.03.2007
  I changed the way LevelInfo class is created by specifying the class instead
 of actually creating it. I added some extra arguments to NewSpecialThinker
 method that allowed me to make Spawn a wrapper around it and move it to Thinker
 class. In compiler I added a spawner method attribute that automaticly casts
 return value. I changed spawning of all thinkers to use Spawn.
10.03.2007
  I made Thinker's Spawn native and added an optional angles argument. I also
 simplified spawning of thnkers in engine.
  I created a template class for mapping of keys to values and changed language
 strings class to use it.
11.03.2007
  I changed RGB table to be calculated in engine.
  I fixed a bug in model rendering in software renderer in 8-bit mode.
12.03.2007
  I split Message class into incoming and outgoing message classes and changed
 them to be derived from Stream.
13.03.2007
  I changed some of the Message class fields and method arguments to be in bits.
  I merged network field serialisation methods by taking Stream as argument.
14.03.2007
  In Stream class I added SerialiseBits method and implemented serialisation of
 some bits of data in message classes.
15.03.2007
  I moved serialisation of bit data from message classes to general purpose bit
 stream classes.
17.03.2007
  I got rid of global incoming message class.
  In bit stream classes I added methods for reading and writing a bit and made
 use of it in some places.
  In datagram driver I removed splitting bigger packets into smaller ones. I
 split signon message into multiple ones and added message queue for a player.
 This allowed me to change maximal message size to be 1024 bytes.
18.03.2007
  I changed sector updates to use read/write bit methods.
19.03.2007
  In PlayerNetInfo class I added all of the methods of Socket class making it a
 wrapper around it. I created client and server versions of it and moved parsing
 of packets to them.
20.03.2007
  In bit stream classes I added methods for reading/writing of integers with
 known maximal value in more compact form.
21.03.2007
  I changed network driver API not to take message classes as arguments. The
 outgoing packets now have a trailing bit that allows me to find out the size
 of the packet in bits.
  I did some tests with datagram driver and found out that with current protocol
 packet compression mostly doesn't give anything so I decided to remove it. The
 length of packet is always known and is not needed in header so I removed it.
 Also the UDP protocol already has a checksum so I removed it. I also changed
 ACK packets to have ACK packet ID in data.
22.03.2007
  I moved ACK packet identifier to the data that allowed me to move ACK handling
 out of datagram driver to PlayerNetInfo class. I also changed reliable message
 sequence ID to be in data and have it's identifier in data that allowed me to
 move handling of ACK sending to PlayerNetInfo class. Now all game packets look
 as unreliable messages. I removed from network API separate methods for sending
 unreliable messages since they are the same as normal messages.
23.03.2007
  I changed PlayerNetInfo to be created when connected and have the same life
 time as underlying network socket.
  I moved unreliable packet ID to data and moved sequencing handling out of the
 datagram driver to the PlayerNetInfo class. Packet resending also has been moved
 to it.
  In Direct3D driver I added additional port to DirectX 9.
24.03.2007
  I moved datagram packet flags to the data. In datagram driver game packets are
 now sent and received without any additional logic.
25.03.2007
  I changed the way messages are sent to be able to save resend message as a
 message and not as outgoing packet data. I also added a method that does adding
 of trailing bit and sending final packet.
26.03.2007
  I implemented support for having multiple messages and ACKs in a single packet.
27.03.2007
  I added network connection state to the PlayerNetInfo class to simplify error
 handling. I implemented support for sending and receiving multiple reliable
 messages. Received out of order messages are kept in a queue untill missing
 messages are received.
  On client side entities are now created and destroyed as needed.
28.03.2007
  I added a destroy Entity network command that allowed me to get rid of InUse
 counter. I also added a flag to identify local player removeing the need to
 use first entity IDs for players.
29.03.2007
  On client side I got rid of the cl_mobjs array.
  I created a thinker iterator template class to simplify this task.
  I changed entity channels to be created and destroyed as needed.
  I renamed PlayerNetInfo to NetConnection since it does all connection handling
 now.
30.03.2007
  I stared to prepare for multi-channel communication by creating a client and
 server general channel classes and moving message queues and message parsing to
 this class. This channel will be used for old-style protocol.
31.03.2007
  I changed remaining entity fields that used old style update to be updated
 using channel. This way I got rid of entity baseline. On server side entity
 channels now will allocate first available slot.
01.04.2007
  In network connection class I started to implement support for generic multi
 channel communication. I changed general and player channels to use it.
02.04.2007
  I made network.h not to be part of gamedefs.h to have less dependencies on it.
  I also changed entity channels to use new channel system. To do this I had to
 implement support for opening a remote channel.
03.04.2007
  I created separate connection classes for demo playback and recording.
  I created a network conext class, currently to handle client and server
 specific access to the level and creation of general channel.
  I changed entity channel to be a thinker channel since I'm planing to use it
 for non-entity thinkers such as level info.
  I implemented proper support for closing a channel. I also fixed handling
 of messages that need to be resent and added an AutoACK flag for demo playback
 and bots where there's no other end to ACK the packets.
04.04.2007
  I split implementation of network connection and channels into separate source
 files.
08.04.2007
  I finished playing Soldier Of Fortune 2, back to work now :-).
  I moved message sequence counters to the connection class to avoid possibility
 of accepting a wrong message after a channel slot has been closed and reopened.
  I made network socket classes to be driver specific, each driver now has it's
 own implementation of a socket.
09.04.2007
  In thinker and player channels I implemented special handling for arrays to
 update array elements that have been changed.
10.04.2007
  I created a level channel that does handling of changes of sectors, sides and
 polyobjs, currently only sidedefs and sectors are handled. I removed multiple
 Set* methods that are not needed anymore.
11.04.2007
  I did some more changes needed for sector updates and implemented updates of
 polyobjs.
12.04.2007
  I finished implementing sector updates.
13.04.2007
  I implemented what's necesary to make LevelInfo to be replicated.
15.04.2007
  I moved most of the fields from level_t structure to LevelInfo class and most
 of them are replicated. I also moved flags that are set from MAPINFO from
 Level to LevelInfo. Time fields have been moved to Level class allowing me to
 get rid of level_t structure.
16.04.2007
  In Doom Firebrand added proper support for foot clipping on liquid terrains
 and did some more improvements to splashes.
  In Hexen I fixed cleric's third weapon and slow running speed.
17.04.2007
  In BasePlayer class I added bIsClient flag so that replication conditions can
 check if it's on client or server side.
  I implemented support for remote procedure calls. Currently both thinker and
 player channels accept them but only player class supports them.
18.04.2007
  I changed sound net protocol commands to use remote procedure calls. Then I
 moved parsing of custom network protocol commands to the player class. After
 that I changed them to be done using remote procedure calls.
19.04.2007
  I changed more network protocol commands to RPCs. I made methods for adding
 static lights native that allowed me to remove all message related natives and
 protocol command definitions from progs. Then I created PlayerReplicationInfo
 class that contains info about a player that is replicated to all clients.
 This replaces scores structure used for intermission and makes more player
 replated data available on client during the game that makes it easy to show
 deathmatch scores during the game.
20.04.2007
  Static lights are now storeed in a list on the server and are sent to clients
 using level channel. This allowed me to get rid of server's signon messages.
21.04.2007
  I fixed PlayerReplicationInfo missing replication conditions for player name
 and user info.
  I fixed wrong map names being displayed in new net game menu.
  Setting a weapon state didn't properly handle case when state time is 0 and
 there's no next state.
22.04.2007
  I changed player structure on client to be recreated for every time when
 connecting to the server.
  I changed ClearPlayer method to reset fields to their default values instead
 of using memset that must not be done is dynamic strings are being used.
23.04.2007
  I changed custom player model and skin names to be stored in player class as
 strings to be able to get rid of model and skin tables on the server.
  I moved some of the methods from Object class to appropiate classes.
24.04.2007
  In player class view states and location are now sent using net replication.
 I also changed sending of movement commands to be done using relpicated fields.
  I moved network role fields to the Thinker class since it needs them too.
  I moved some more methods from Object class to it's proper location.
  I added a time field to the texture manager class so that warp textures don't
 have to reference client side specific global variables and to make it more
 abstract.
25.04.2007
  I changed keepalive packets to be simply empty packets and disconnect to be
 done by closing the general channel.
26.04.2007
  I moved sending of the level info to the level channel.
  I fixed Hexen's world timer, changed it to be float.
  I changed sending of client and server infos to use RPCs.
27.04.2007
  I got rid of multiple client signon stages.
  I added proper rounding of some of the values being sent over the network.
  The time used in intermission is now a field in LevelInfo set on the server.
  View origin is now set using a RPC to avoid jerkiness because of the rounded
 vector values.
  Demo messages now also record the current time. After this there's no need to
 send server's time to the client in every frame.
  After that general channel is only used for string commands so I could get
 rid of the command itself.
  In datagram driver I changed the use of message classes to use bit stream
 classes instead.
  I cleaned up message classes from now unused methods and fields.
28.04.2007
  I got rid of the sv_player global variable.
  I changed menus and console to be drawn while not yet fully connected to the
 server.
  I moved client side update of entities to the actor class and made it for all
 types of thinkers. I also moved update of particles to LevelInfo class.
  I changed current time on client to use time fields in Level class.
  Aparently latest version of FLAC library crashes if non-FLAC data is passed
 to it so I added a check for FLAC header before doing it.
  I fixed some crashes when changing levels while playing with bots.
  I updated Doom weapon models to Alex Bomberman's ones. I fixed drawing of
 models with custom scale and offset properties.
29.04.2007
  I added name constants for all engine events and added or improved usage of
 names to have less name lookups during the game. I had to add a separate set
 of macros for executing an event using vertual function index since compiler
 tries to use name constant as virtual function index.
  Now that both general channels are used only for text, I could merge them and
 rename it to control channel.
  I changed creation of channels so that I don't have to abort game if there's
 no free channel slot is available.
  I fixed user info not being sent to the server.
  I made closing of open channels when a thinker has been destroyed not to
 depend on client and server specific global variables.
30.04.2007
  I changed drawing of text to use dynamic strings.
  I fixed a crash when destroying a thinker that doesn't belong to a level.
  I fixed a typo in maximal number of channels.
  I updated version number in preparation for a release.
01.05.2007
  I fixed bad behaviour when server decides to modify player's movement values.
  Some makefiles needed some attention.

05.05.2007
  I implemented test version of standalone mode for single-player. With new net
 code it was very easy to do.
  I decided by default to disable GL point parameters extension.
  I fixed missing initialisation of paused state of stream music player.
07.05.2007
  It turns out that in subclasses of a class with virtual methods GCC starts to
 add fields on unaligned parent size offset, that caused class-size error on
 64 bit systems. I added a proper check for this.
10.05.2007
  I created s separate source file for BasePlayer class, I moved most of it's
 methods there.
18.05.2007
  I fixed some remaining cases when memory wasn't freed on exit.
19.05.2007
  In Entity class hidden flag wasn't replicated to clients, I fixed that.
  In render drivers I implemented support for having different fog setting for
 each polygon.
  I implemented a general method for pasing colour values with possibility to
 use colour names that are looked up in a table from X.Org.
20.05.2007
  I implemented support for custom fog MAPINFO commands and line special for
 setting fog parameter to a sector.
21.05.2007
  In Doom I implemented support for Heretic finale types specially for Heresy
 project.
  I moved PVS checks in network update to connection class.
22.05.2007
  I hunted down a memory corruption bug I introduced some days ago.
23.05.2007
  I added proper configure check for OpenGL libraries.
  I fixed force field damage amount and force.
  I fixed crash when destroying a Heresiarch with Thing_remove.
  I fixed MUS to MIDI converter that forced all tracks to start at 0 tick.
24.05.2007
  I tried to play a ZDoom level from last /newstuff chronicles and found some
 bugs, such as wrong slope calculation with Plane_Align special and wrong
 translation of Boom's generic line specials. This level didn't have the
 REJECT data, so I added a proper check for this.
  I moved Entity's world related methods to a separate source file and others
 to Entity's main source file. The rest of sv_ent moved to sv_main. I also
 split handling of terrain types to it's own source file and renamed sv_swtch
 to p_switch.

                            VERSION 1.23.1
******************************************************************************

25.05.2007
  I fixed Doom 2 boss spawning monsters with pitch angle making models to
 appear tilted.
26.05.2007
  I changed handling of gravity back to the original. I added Gravity field to
 Entity to be to set different gravity for a thing that can be used to simulate
 low gravity flag in Heretic and Hexen.
  In Doom I renamed Actor's Enemy and Instigator fields back to theur original
 names.
27.05.2007
  I renamed Actor's Enemy and Instigator fields in other games.
28.05.2007
  I implemented support for byte type in VavoomC and changed some fields in
 engine classes to bytes. I also implemented support for dynamic arrays.
  I removed video modes lower than 640x480 from the menu.
29.05.2007
  I removed automatic stripping of executables in default build.
  I fixed problem with colourmaps in 8-bit mode in software renderer.
  In VavoomC I added methods to insert and remove data in dynamic arrays and
 changed assignment to an element out of bounds of an dynamic array to grow it
 to the needed size.
30.05.2007
  After thinking for a while I found a very simple way how to implement
 iterator methods. The method returns an instance of an iterator class which
 is pushed to a stack of current iterators. As a test I implemented iterator
 of thinkers.
31.05.2007
  I got rid of the remaining macros in common package. After that I could start
 implementing my own preprocessor. I already implemented handling of ifdef-s.
01.06.2007
  In vcc I implemented handling of include directives and comments that allowed
 me to get rid of the old preprocessor library.
02.06.2007
  I fixed crash when changing a level in standalone mode, cleaned up level
 render tests.
  For network updates I implemented setting up a visibility table using angle
 based clipper. I also increased number of network channels since 256 seams not
 to be enough.
03.06.2007
  I converted block lines/things iterators and path traverse to the iterator
 classes so that in progs I can use foreach operator with them and get rid of
 callback methods.
04.06.2007
  In progs I changed path traverse to iterator. The block things iterator is
 always used to iterate blocks in a given radius, so I started to implement a
 method that wraps around block things iterator and common code around it.
  I fixed compiling progs on Windows.
05.06.2007
  In progs I added a method that disconnects a bot.
  I finished work on radius things iterator that I started yesterday and made
 it to be an iterator method. After this progs don't touch blockmap fields in
 level class anymore.
  I simplified calculation of replication condition of a method in RPC.
06.06.2007
  I removed support for nosoundclipping mapinfo command since sounds at maximum
 hearing distance are almost inaudiable, so it basicly does nothing.
  I changed bots not to have a network connection at all.
  I made standalone mode to be used in single player by default.
07.06.2007
  In progs I implemented support for non-native static methods.
08.06.2007
  I implemented support for EDGE's sprites with 16 rotations.
  I added a size check for reject lump. I also check if it's filled with all
 zeroes in which case it can be discarded.
  I implemented a blockmap builder that rebuilds it's missing or bigger than
 64k and most likely corrupt. Internally it's now stored using integers that
 removes some of it's limitations.
  I moved array of active sound sequences to the Level class.
09.06.2007
  I fixed support for Boom's height sectors.
  I implemented support for ZDoom's compressed GL nodes.
  I added support for texture offsets in PNG textures.
10.06.2007
  I added iterators of classes, all objects and active players, they could get
 usefull sometimes.
  Some splash chunks didn't have no-splash flag set that caused almost endless
 splashing.
  I added stubs for all unimplemented MAPINFO commands, many ZDoom levels can
 now be loaded unmodified, including KDIZD.
  I added support for ZDoom's sloping thing types.
11.06.2007
  I started to rename class to the names used by ZDoom since these are the
 names that are used in some extended ACS commands and in some scripts.
12.06.2007
  I continued renaming.
13.06.2007
  I finished renaming.
14.06.2007
  I changed the way Heretic's key gizmos are handled.
  Today is Vavoom's birthday, time for a release.

15.06.2007
  I'm gonna start common code from Actor classes to the EntityEx class. This
 way it will be easier to maintain it.
  I moved common Actor fields to EntityEx class.
16.06.2007
  I created PlayerEx class that will have common Player class code.
17.06.2007
  I merged Actor's main physics methods.
18.06.2007
  I merged other Actor's core physics methods.
19.06.2007
  I merged methods for bouncing, splashes and friction.
20.06.2007
  I merged falling damage types and made them MAPINFO configurable, merged
 radius damage.
21.06.2007
  I merged aiming and shooting methods.
22.06.2007
  I cleaned up aiming and shooting and created aiming method to handle aiming
 used by Hexen's close range weapons.
25.06.2007
  I changed AimEx to return line target as a result and direction in an out
 parameter.
26.06.2007
  I got rid of per-object line target field, merged teleport move and added
 a damage type parameter to the Damage method.
27.06.2007
  I fixed Doom 2 finale cast.
  I merged teleport, various movement related methods, melee and missile range
 checks, looking for a player or monster.
28.06.2007
  I merged basic monster AI utilities, spawning of missiles.
29.06.2007
  I merged spawning of payer's missiles.
30.06.2007
  I fixed wrong prototype for StrReplace method, got rid of pickup message
 arrays in Heretic and Hexen.
01.07.2007
  I started to merge Damage methods.
02.07.2007
  I merged damage methods, replaced damage flags with damage type field, got
 rid of LavaInflictor class.
03.07.2007
  I merged death methods.
04.07.2007
  I merged nightmare respawn, touch and line hit event methods.
05.07.2007
  I split makefile in basev directory into sub Makefiles.
  I moved some common methods to LineSpecialLevelInfo.
  I implemented net replication of references to thinker objects that have an
 open channel.
07.07.2007
  I moved 2 missile spawn methods from Hexen to EntityEx. Somehow I managed to
 miss them.
  I moved OnMapSpawn, SeekerMissile, DropItems and some other small methods to
 EntityEx. I created a ScriptedEntity class for state action methods and moved
 basic AI state actions to it.
  In Doom as a test I merged Weapon and WeaponPickup classes.
  I moved net serialisation of classes, states and names to objects map.
08.07.2007
  I moved spawning of things on a map to LineSpecialLevelinfo.
  In Doom I created a separate class that holds the Boss brain global state.
 In Heretic I moved mace handling code to mace spot class, removed global array
 of D'Sparil teleport spots.
09.07.2007
  I fixed Dehacked support.
  I moved Tick, SectorChanged and ClientTick to EntityEx.
  I started work on inventory system by creating and Inventory class. I changed
 game specific pickup base classes to inherit from it. In Heretic every pickup
