Original Soundtrack or Open-space technology?

there's THC going on in this game too, at different levels of "high."

to hit chance?

or delta-9 tetrahydrocannabinol?

Must be D9THCB in this case :)
Oh, according to this, it should be Original Soundtrack after all :)

Changelog for patch 1.2.0.0158 / GOG-9 (Windows) (added 12 December 2016):

- Adds Spanish language to the game

Changelog for Patch 1.3.0.0001 / GOG-10 (Windows) (added 23 December 2016):

The final content update expands the endgame, which makes it difficult to describe the update without spoiling it for those who either haven't played the game yet or just started playing it. Thus I have no choice but to be cryptic about it:

- If you decide to return to the temple and bring one of the lords with you, you'll get a proper road trip with various challenges. Different lords will have different escorts and ways of dealing with said challenges.
- You'll see the changes taking place in and around the temple, which will explain a lot, and witness a certain conversation.
- If you saved a certain guildmaster, he'll make an appearance and you might regret saving his ungrateful ass.
- A certain unscrupulous gentleman might be convinced to tag along and get his own, much anticipated ending
- If you did nothing of importance in the third chapter and a certain ritual took place without you, it will unlock an exciting new career in manual labor and pyramid building.
- If that ritual did take place without your knowledge, it will change your options at the temple.

While it's the last content update, it's not the last update. We're still planning to transfer some changes from Dungeon Rats, a tactical squad-based RPG set in the AoD world, but it will take some time as such changes can easily change balance.

Changelog for Patch 1.3.0.0008 / GOG-11 (Windows) (added 28 December 2016):

- Fixed a minor crafting issue.

Patch 1.5.0.0018 (28 March 2017)

This update transfers all applicable changes and improvements from Dungeon Rats, our combat-focused, party-based spin-off set the AoD world.
While the changes are too numerous (and in many cases too minor) to list, here is an overview:
Overhead combat info
New passive for axes
Mouse cursor shows enemies' HPs
Expanded info on weapon types
THC, CS and ADC stats on area of effect attacks.
Tweaked CS formula for aimed strikes.
Ranged weapons use Perception for aimed: arms and legs attacks
Whirldwind effect for daggers, swords and 1h spears is bleeding instead of knockdown; higher chance to score.
Bombs: increased damage and vsDR bonus; the center of explosion does more damage and increases critical strike chance by 50% (goes down with every tile). CON is more effective. 25 + Center of Explosion Bonus - (Victim CON-6) x25; better visuals and sound.
The Crafting screen now separates schematics by weapon type and armor material and orders them alphabetically.
You can now select techniques without the required materials, to preview the bonuses.
No further content or mechanics updates are planned at this point. All translations are now up to-date as well. We'd like to thank you for your support and willingness to try different games.

Is it just me, or am I losing combat turns in this new update? I love this game, and I don't want to start a fire here, but I have no idea why the opponents are getting two turns or starting combat before me after loading combat autosave.

I just saw a post on RPG Codex from the creator of the game. He said it's a bug they've already identified and fixed, so there should be a solution quite soon.

Thanks so much. I thought I was going crazy or my compy was on the fritz.

Changelog for Patch 1.5.0.70 (added 07 April 2017):

- fixes some reported issues

I got no update notification for this and only see a completely new installer with no patch. Is this how it is for everyone else?

AND WHY!?

It's a good thing I make a habit of looking at game-specific subforums on the regular.

These installer files also don't make sense. 1 of 2 and 2 of 2, but they're both .exe files just one looks like a 64bit and one looks like a 32bit?

Update flags have been pretty unreliable for quite a while now. You should check the "What did just update" thread, where muntdefems posts all the daily updates MaGog intercepts. He includes a list of updated games at the beginning of his post(s), so you can easily check if there's anything relevant to you.

It's also been a while we mostly get updated installation files instead of standalone patches; Age of Decadence, The is apparently no exception.

As for the installers, I can only assume from here (I don't own the game) that there's a 32bit one and a 64bit one, and not a single installer divided into two parts. Probably best to poke Judas for clarification.

Hope this helps.
