Steam forum threads seem to indicate there are issues with the Mac build after the update (maybe related to the transition to 64bit). So that could be something holding that build back. Not sure about Linux. Might be something similar, I guess.

edit 10.06.21: regarding popups for getting an asmodee.net account / newsletter -> "StormLord1975" tested new version (thanks again!) & this "feature" ist still active. Will get in contact with asmodee support. Sorry for offtopic, will continue in the dedicated subforum thread for this very topic.

Likely this: The Linux and Mac versions still didn't update, and still no sign of the free DLC the game got on Steam.

Warhammer: Shadow of the Horned Rat just received an update but there is no changelog.

Interstellar Space: Genesis updated to v 1.3

NEW

New 'Surrender Pact' diplomacy option! Empires facing inevitable defeat can now offer or agree to sign a surrender pact thus removing the need to completely eliminate them from the game. As subject empires, they provide their overlord a hefty percentage of their surplus credits, research points, culture, ship support and strategic resources each turn. Subjects vote for their overlord and contribute to all victory types. An overlord and their subject can make diplomatic coordination requests as if they were allied, but a subject's options are limited. 56 new lines of dialog were added to accommodate the surrender pact diplomacy interactions.
New 'Alliance Victory' condition - When an empire wins, all its allies share victory. It can be enabled or disabled in the new game set up screen.
Steam achievements feature added! 57 achievements, which include 3 hidden ones and 7 for the first expansion pack, Natural Law. The achievements are also displayed in-game in a dedicated 'Achievements' screen.
New 'AI Aggressiveness Modifier' option in the 'New Game' screen allows tweaking the desired aggression level by the AI. With higher aggressiveness, the AI will tend to be more hostile, attack more and declare war more often. It will also be more reluctant to sign deals. The opposite effect for lower aggression than normal.
Maximum number of players is now 10 (was 8 before).
One more zoom-out level available in the bigger map games.
Now possible to set production and research speeds for each player as low as 1% and high as 300%, with a granularity of 1% steps (the 25% steps option is kept along this new high granularity option).
New Government biases provide for additional flavor and early tensions between empires with different and opposing government types. The effect wears off with time, faster in the easier difficulty levels.
Diplomacy UI revamped! The diplomacy dialog screen is now displayed in full screen and the ambassador character is presented much larger, allowing for much more of the character to be seen and the different animations depending on their mood.
New 'Balanced (no ships)' colony AI governor filter allows for balanced colony automation but without ships being constructed by the AI.
New UI-scale slider option in the 'Game Settings' allows enlarging the galaxy map icons and labels, and also the information presented in the system view, which may be especially useful when playing the game in very big monitors and TVs.


AI IMPROVEMENTS

Significant improvements made to the AI in how it invades outposts. It now takes outposts more diligently and at all times it finds it's opportune, especially in the higher difficulty levels.
The AI now plans better on what ships are best suited to be used as escorts given the current circumstances (e.g. to escort civilian ships on their colonization, exploitation or exploration missions). Before, the AI could use ships as escorts that were best suited for other roles (e.g. invasions, defense) leaving systems unprotected or taking too long to launch an invasion.
The AI now goes after Space Monsters more, especially when they guard particularly important systems, not only for their colonization rating but also for their exploitation potential.
The AI now considers building more capital ships and bringing more ships to battle and is also a bit more aggressive in the late game in the higher difficulty levels.
The AI will not send suicidal runs against orbital stations addressed (e.g. 1 frigate against a starbase).
The AI will not be as reluctant to go to war as before (more likely to go to wars in the higher difficulty levels than before, especially early for the warmonger race affinities).
The AI now handles gifts more sensibly. Previously, it could be too easy to spam the AI with small gifts for big diplomatic benefit.
The AI will now make it less obvious where it is amassing its ships when preparing for an invasion.
The AI now considers razing enemy colonies and outposts (it didn't before for design reasons).
The AI now considers asking for a peace treaty more if they happen to be in a very bad situation even if they are furious towards their rival.
The AI algorithm to consider establishing outposts was improved which resulted in a more diligent and aggressive approach to establish (and re-capture) mining and tourism sites on accretion disks, especially when these have strategic resources.
The AI now prioritizes scanners and drive technology a bit more, which boosts their operational effectiveness further.
The AI now fires all its weapons in combat when it cans where before it could miss the opportunity to fire some weapons due to not having enough angle aperture to fire at their primary target. Now, AI ships consider other targets if they cannot fire at their primary one.
The AI ships now focus and spread their fire in combat more sensibly, resulting in more aggressive, concentrated and effective attacks.
The AI now also more effective at finishing off their targets more when they are in bad condition where before the AI ships could change their targets in the middle of the fight and not finish off AI ships when it would be better if they did.
AI combat enhancements made to make sure ships spend all their actions in the best way possible, prioritizing firing actions and making sure ships can and will fire all of their weapons as much as possible.
The AI ship design algorithm now considers equipping weapons with different fire arcs more when they think it can result in more effective designs.
The AI now refrains from using tractor beams on its own mind controlled ships.
AI now considers using tractor ships before other AI ships fire at targets.
AI combat improvements on which ships the AI chooses to use first in battle and in which order.
Mind control Titan ability now being considered by the auto-resolve algorithm.


BALANCE

Ship construction cost reduced from +50% to +25% in the 'Low' Ship Support penalty level (less than 10 negative SSP).
Ship Attack and Ship Defense penalties reduced from -20% to -15% in the 'High' Ship Support penalty level (less than 25 negative SSP).
New 'Very High' Ship Support penalty level causes -20% Ship Attack / Ship Defense, +100% ship construction costs and 50BC maintenance per point below the -150 SSP mark.
New 'Extreme' Ship Support penalty level causes a 25% reduction to all ships' Ship Attack (accuracy) and Ship Defense (evasion rating), +300% ship construction costs and 250BC maintenance per negative SSP point when SSP goes below the -350 mark.
Auto-resolve improvements: Point Defense weapons were too much of a factor in countering missiles; also, fleet size had too much weight in the combat auto-resolve algorithm.
Interstellar Geology culture perk now provides a flat +2 strategic resources' bonus instead of a +50% bonus, as that was causing too much production and other excessive effects.
The Neutronium armor coating tech now provides immunity to beam damage when 8 sources of neutronium are available, where before 5 sources were enough to confer immunity making the effect a too powerful one. Each source now provides +12.5% beam damage reduction per available source, where before it offered +20% per source.
Gifts not as powerful of an effect on the Sulak, Cerixx and Human race affinities in diplomacy deals.
Gifts' positive effect wears off faster on the Draguul, Sulak, Human, Palacean, Kaek and Nova race affinities.
Space mirror array now costs 15 BC to maintain, was 10 BC before.
Utopia government now has a -25% research penalty on defense technologies.


GAMEPLAY

Warrior Code unique ability now grants +15% morale per ongoing war (Draguul affinity, also available to custom races).
Tribute deals are now automatically cancelled when war is declared.
Bomber bays and fighter bays now factored in the auto-resolve calculations.
When the odds are overwhelming in favor of the invader, during a planetary assault, the collateral damage applied when it loses was halved.
Tamara Adams had incorrect leader skills that resulted from a development testing mistake. She now has the scientist, astronautics and activist skills, as designed for this leader. She had espionage skills before.
An Alliance pact now provides information on all colonies and fleets the allies have to their allies, like the espionage intel-gathering expert skills does. This was designed but not working as intended. Now it is in the game.

Changelog, part 2

PERFORMANCE

Turn-time performance improvements, especially noticeable in the late game.
Loading games much faster now.
Significant combat performance improvements. Combat could start to lag after several combat sessions. This was fixed.
Major performance improvements for 4K resolutions. The game could be a bit laggy in some places in 4K monitors. That is now fixed.


SOUND & MUSIC

Diplomacy "angry" tunes now play when an opponent's ambassador leaves when treaties are broken and demands are made that are not accepted by the ambassador.


Okay, after about 20 tries in various ways, I give up, GOG doesn`t want me to post the whole changelog.

Pile Up! Box by Box

Updated to 1.0.13 (Galaxy & Offline Installer)

Very detailed changelog from Steam: +++


Linux & Mac Offline installers now updated as well.

The latest patch for Mechwarrior 5 has arrived but no changelog is currently available on GOG and most likely never will be so i copied it from Steam.
