There are a various set of different versions of the game available. This explains the major differences and links to patch notes where possible and for the most modern patches post-1.69 the relevant script and engine changes.
The version identifier is also used for matching a module against a game edition for compatibility. For instance a NWN:EE 1.80 version of a module will be tagged in the module.ifo file under the "Mod_MinGameVer" string as 1.80, meaning you are unable to load this in a Diamond Edition version of the game at all.
With NWN:EE the versioning numbers got longer, information about this is available below. For NWN:EE specific functions you can find them categorised here.
1.69 - Diamond Edition
The last Bioware patch released 9th July 2004. The details of this and all the previous Bioware patches are available on the NWN Fandom Wiki Patch page.
1.70 - 1.73 Fan Patches
Shadooow created a set of Community Patches once Bioware had finished patching. These were numbered 1.70 - 1.72 (1.73 appears not to have come out so this version is essentially unused). This is still under development but contains no new scripting or engine functionality. You can find the vault page here.
1.74 - NWN:EE
The first versions of NWN:EE by Beamdog were beta versions before the game came out. We now step into using both a major ID and a development ID. Several development IDs are used throughout a major ID number. This means newer or older clients can connect to newer or older servers (eg; visual enhancements don't need a server to be updated, while a server running a script differently doesn't need the latest client). Major bumps are generally done for architecture reasons, or netcode reasons.
These are links to the various patches, any notable engine changes related to scripting, or script events/fixes, will be noted to the side.

- 1.79.8193 December 3rd, 2019 - Stable release of 1.79 - The features below may have been in past versions - the patch notes on steam are not the best!
- New development features:
- Debug Menu (CTRL + SHIFT + F12)
- "development" folder that loads changes live in-game and is priority loaded above override folder, erf, hak and module files
- Aave added a script command to JIT-compile and run a chunk of NWScript.
- New script commands (Some available in previous development versions):
- SetPhenoType: The constraint condition was too narrow in clamping the phenotype; this has been fixed.
- SetName() on areas now sends the configured language, instead of English.
- CopyObject now copies plot flag on creatures and items.
- Fixed StoreCampaignObject/RetrieveCampaignObject() not properly storing/retrieving the faction of a creature.
- A bug in the creature serialisation code (for StoreCampaignObject) has been addressed where it would erroneously embed transient object IDs for inventory items, resulting in issues when loading this creature again in a persistent world setting.
- Player characters stored/copied now end up in the Commoner faction (it used to be a the PC faction; with no valid party).
- Script calls that serialise/deserialise objects (StoreCampaignObject and CopyObject as of now) can now work with the following object types: Creatures, Items, Placeables, Waypoints, Stores, Doors, Triggers.
- (GetAbilityBonusLimit etc. related) The effect limit configuration keys have been uncapped. They used to be limited to [1, default]; they now are [0, 255]. Beware: You may run into strange behaviour if you exceed a total bonus/penalty of -128, 127 or 255 regardless of configuration; since some values are internally typed with 8 bits.
- Scripting: The effect limit accessors now adhere to the configuration constraints. Values set through these will always override the user-configured values for the running module only.
- New development features:
- 1.79.8193.1 December 6th, 2019 - Class Stat Gain: We fixed the NWScript function GetAbilityScore() not including glass stat gain abilities when calculating the return value.

- 1.79.8193.4 December 13th, 2019 - The script call ActivatePortal() has been fixed to no longer show “Cryptographic Handshake Error”. A small memory issue in RESREF handling was addressed, that could occasionally crash clients when transitioning via ActivatePortal().
- 1.79.8193.5 December 19th, 2019 - Fixed CopyObject not duplicating a item if the target inventory or location was not valid.
- 1.79.8193.6 January 13th, 2020 - Base Items can have non-hardcoded feats for each of the focus, specailization, etc. You can have some custom spellcasters - kind of. New scripting function SetTextureOverride.
- 1.79.8193.7 February 27th, 2020 - Fixed GetCasterLevel() on AOEs/SLAs erroneously invalid values. CopyObject() with a new tag specified no longer erroneously adds the object to the old tag lookup. ActivatePortal() now properly uses relays if needed. The script editor no longer freezes when trying to compile **/**.
- 1.79.8193.8 - GetSpecialization, GetDomain, PostString added. New pathfinder added.

- 1.80.8193.12 May 6th, 2020
- Fix script commands not properly accessing area UUIDs. #41
- DestroyArea() now behaves the same as DestroyObject(): Instead of destroying the area immediately, it schedules it for removal immediately after script exit. This fixes accessing freed memory when destroying an area from an area event.
- GetCasterLevel() now returns 0 for AOEs instead of crashing. #34
- 1.80.8193.13 - Stable and contains fixes/new things from above, still 1.80 (backwards comaptible to 1.80.8193.9), but more feature complete.
Some new commands may be previewed in versions not for general release. These won't be documented here.
