Version 6.0.0

- NVSE arrays heavily optimized for performance
- NVSE cosave saving and loading heavily optimized for performance
- Optimizations in UI functions and string formatting functions
- Automatic cleanup of string variables and array variables (no more string and array var save bloating)
- Mod authors should however continue using Sv_Destruct and Ar_Null to prevent save bloating for people using older versions of NVSE

- Examples:
- Func0 && Func1 - Func1 won't be called or evaluated if Func0 returns false
- Func0 || Func1 - Func1 won't be called or evaluated if Func0 returns true

-
Version 5.1b4
- versions where not coherent.
-
Version 5.1b3
- CTD when starting a new game with the NoGore edition of NVSE.
-
Version 5.1b2
- Update3D works again.
-
Version 5.1b1
- Possibly Important: ExtractArgs used in Compiler Override mode was always returning true even if the argument types were wrong.
- pretty much all commands are affected by that change so it is possible for your mods to suddenly display errors they weren't before.
- Change definition for SetWeaponAmmo and SetWeaponProjectile to allow for AnyForm.
- Change a few functions to take either an actor (ref) or an actorBase (npc). It was implemented in the code but not in the function definition.
- GetBaseSpellListSpells, GetBaseSpellListLevSpells, GetBasePackages, GetBaseFactions, GetBaseRanks and GetHeadParts.
- Fix ToggleUIMessages(True), thanks to RoyBatterian
- SetPermanent applies to reference as intended rather than to base forms (as that would simply duplicate IsQuestItem).
- Possible bugfix:
- Added multi threading handling to the calling of functions due to hard to track reports of function call failling.
- I have no idea if it will help, but..
- Also, those calls error reports have been stligthly changed to help distinguish possible causes.
- GetSourceModIndex will accept any form as the optional parameter.
- Remove restriction on Set3D for the playerCharacter (highly experimental) and known to have a visual glitch. When compiled in debug mode it is not working at all.
- GetPermanent should persist accross saves now.
- SpecialIdles for NPC and Creature:
- [actor or npc or creature].GetNthAnimation index [npc or creature or actor]
- returns the nth animation selected on an NPC or a creature as a string_var
- [actor or npc or creature].AddAnimation animationName [npc or creature or actor]
- Select an alternate animation for an NPC or a creature
- [actor or npc or creature].DelAnimation animationName [npc or creature or actor]
- Deselect an alternate animation for an NPC or a creature
- [actor or npc or creature].DelAnimations [npc or creature or actor]
- Deselect all alternate animation for an NPC or a creature
- [actor or npc].GetClass [npc or actor]
- Returns the class of an NPC
- [actor or npc].GetNameOfClass [npc or actor]
- Returns the class name of an NPC
- ShowLevelUpMenu
- Optional Alternate Update3D for the player (set AlternateUpdate3D to 1 in nvse.ini section [RELEASE] and/or [DEBUG]). It has an effect but with a huge visual defect that should be temporary.
- Misclaneous: New data interface for plugin authors needing internal offset to NVSE code.
-
Version 5.1.6
- Fixed heap corruption bug
- Fixed hacky piece of code making recompiles buggy
- Everything should be a lot faster since NVSE was compiled using a newer toolset
-
