It's not in there but I can't seem to find it anywhere, either on the download page or SVN T_T

Re-downloaded it, still don't see it in the release anywhere. Not a clue what's going on :/

There are war3dll.dll and war3dll.so both of which are in the extensions folder already if that's what you mean however.

update sm

Download broken.

Get this error when opening the .rar.

"D:\css\Downloads\War3Source\War3SourceP1.2.3.6.rar: Unexpected end of archive"

I've tried re-downloading several times with the same result.

Updated the SVN to 1.2.3.8

Added "Buyprevious" say command (Same as War3_RestoreItemsFromDeath except it works as a say command)
- Buyprevious is a player say command that allows players to auto buy all items
- they had from a previous death.  It will not be charged for the items they already own
- that matches the list from a previous death.
/**
 * When a player dies, this command record's their shopmenu1 items.
 * When you use this command, you are telling it to restore their items from death.
 * It does all the math as far as taking gold or cs money for items restored.
 * It will let the client know what items are discarded and/or bought.
 * It will also only buy until the client goes broke. (if client can't afford a item, it wont buy the item).
 * If the client already owns some items from the list from death, it will not charge them.
 * It only charges for the items that the client must buy to match the items from death.
 * It discards items that does not match from the previous death list.
 * Note: The no cost method still needs work.
 * @param client: Client index
 * @param payforit: false = no cost, true = charge
 * @param csmoney: true is cs money, false for gold.
 * @return The return value will be true if it is successful.

native War3_RestoreItemsFromDeath(client,bool:payforit=true,bool:csmoney=false);

Added:

enum W3Buff
-bImmunity_Items

stock bool:W3HasImmunity(client,War3Immunity:immunityindex)

added:
   if(immunityindex==Immunity_Items){
      return W3GetBuffHasTrue(client,bImmunity_Items);
   }

Yes now you can check for immunity to items! Hurray!

enum W3EVENT
-DoShowPlayerItemsOwnTarget, ///EventArg1 = target = the person whos items is shown, client=SHOW TO

For your war3source.cfg:
/*
*  1 = Allows a player to Show the list of items a target player owns when a the player uses the say command "playerinfo" [default]
*  0 = Does not allow a player to Show the list of items a target player owns when a the player uses the say command "playerinfo"
*/
war3_show_playerinfo_other_player_items 1  //0 disables showing other players items using playerinfo. [default 1]

Players can now see only their list of items by using the say command "myitems"
