I don't know, but the previous files were broken; trying to unzip them (or even just run "unzip -l on them") would yield an error message.

Downloading them again now, so I'll see if they can be unzipped once that's done.

Edit: "unzip -l" now works on all of the files. Also, there are two parts for each game's goodies, while previously there was only one (broken) part.

So, yes there was indeed an update.

Stellaris was just updated to version 2.6.0.4.

RimWorld

Update 1.1.2575 (16 March 2020)

Implemented renounce title button on pawn bio tab. You can now have your royal colonists renounce their title if you wish.
Implement mech shield generator charge cycle. Shields now go down for a random day every 10 days, if you're willing to wait.
Mech cluster condition causers and mortars now sometimes take several days to initiate threatening the colony. This gives more time to prepare and attack the cluster.
We now generate random rewards only up to 5500$, the rest will go into market value fillers like gold, plasteel, and uranium. This avoids absurd rewards with large numbers of unique quest items in modded or ultra late-game scenarios.
Added bulk recipes for pemmican and drugs.
Restricted hunting decrees from targeting colony animals.
Make mortar/bullet shields shut down when the cluster is defeated.
Added new visual effects that play when something is disabled by EMP (makes it clearer when mechs and their builds are EMP-affected).
Monument blueprints are now automatically placed when a monument marker is placed. They're also automatically removed when the player cancels the monument.
Reduce hospitality threat frequency from 18h to 24h and adjusted rewards to match.
Reduce love enhancer impact 50%.
Give more time for harvest decrees, especially with fast-growing plants.
Fix: Trade request quest can request and give the same ThingDef
Fix: Trade request quest generation fails in rare cases
Fix: Harvest decrees can ask for cave plants.
Fix: Missing CanPawnAcceptQuest check in QuestsTab.
Fix: Tribal faction namer uses undefined key.
Fix: Traveling colonists not being able to accept quests and refactor MainTabWindow_Quests.
Fix: Pawns losing ownership of their bed/throne if sent in transport pods.
Fix: Random error from NaturalRandomQuestChooser; total weight is zero
Fix: NamesFromRulepack debug output causes errors when root keyword isn't r_name.
Misc minor typo fixes.

Not exactly true. The devs have posted the changelog for both 1.075 and 1.076 (standalone installers were updated from 1.074 to 1.076) in the game forum since before the weekend.

Devs/pubs posting changelogs/patch notes in the game forum without it made available in game libraries isn't that uncommon for quite some time now.

Low Magic Age

Low Magic Age has been updated to Version: 0.91.23.10 (Offline installers now updated)

No changelog

Ancestors Legacy got an update flag. No changelog, though.
Version "64623.1" ?

Another update for Stellaris. New version is 2.6.1.1.

Terminator Resistance updated to 1.030.
Galaxy only for now.

SiN Gold was updated thanks to Nightdive Studios. It's now on version 1.13sdk. The update is currently only available on GOG Galaxy but as usual the offline installers should be updated in a few days max if nothing unexpected happens.

Here's the changelog taken from the not-so-drm-free gamestore:

Ah glad this did hit. I saw a tweet about it. Now if we could get SiN Emergence here; it might be overpriced at $10 but still, bring it.

The whole thing is pretty awesome, but this stuff is especially good(after how the one company BUTCHERED all digitally sold versions to remove various artwork).

The bit about them doing "as good a job as was done with the new version of Blood" has me a bit worried, though....but hopefully it'll also be as good.

(also hopefully they won't pull the old version from the store and only sell the new one with the old version as a "freebie")
=========================================

That and i'd like to see someone finish the proposed other chapters/parts the other company had planned.

Well Atari is not involved with this one so there shouldn't be any bullshit happening this time. Also there is no new version. It's the old SiN Gold that's being sold here but patched again after a long time.
