Sorry, I'm still confused.

setup_broken_sword3_2.0.0.1.exe was not modified since March 2014, when there were still four language pack files, one each for french, german, italian and spanish. All four of those are now gone.
Since August of last year there is a separate installer exe for french.

Now the language packs are gone, but there are no separate installers for german, italian or spanish. So it looks to me like the translations are gone too. What am I missing?

The game has two installers:

(1) Windows installer, English+German+Italian+Spanish, ver. gog-1 [setup_broken_sword3_2.0.0.1.exe; Fri, 24 Jan 2014 02:51:47 GMT; 1,185,798,192]

(2) Windows installer, French, ver. gog-3 [setup_broken_sword3_french_2.1.0.3.exe; Mon, 17 Nov 2014 12:34:44 GMT; 1,174,313,240]

which, AFAIU, together cover all the five languages. The language packs could probably have been deleted back in 2014, but somebody forgot to do it.

P.S. Based on GOG data. Did not try to actually install the files.

ok to be clear ^_^

i will take my example : (and that's not a good example :[ )

since i download only english & french installers (french installer if avaible)

if i only use the english installer then i don't need anything else : so the installer is still the 2.0.0.1 (gog-1) : file name is "setup_broken_sword3_2.0.0.1.exe" (as mentioned above the english installer seems to have others languages integrated except french)

now if i want to play the french version, i need to download the french installer 2.1.0.3 (gog-3) file name is : "setup_broken_sword3_french_2.1.0.3.exe"

previously i have only to download the language pack, now it's the full installer.

that's the reason i stated it's much bigger.

to access to different language there's the pull down menu (with different languages)

is that ok ?

i think in your case , you need to follow what mrkgnao said, unless you want to play with the french version ;P
heck i didn't even know the french version got a special treatment o_o ,i know that's not very logical.

changelog is for the MAC version ;)

windows's one is GOG-23
mac's one is GOG-14

the universal patch is useless (unless you have an older version and don't want to redownload the full game)

well, adding the gog version in the changelog header isn't great , if there're different version number in each OS.....it just adds confusion if you ask me.

A-ha. Thanks for clearing that up. Maybe the version should have an OS code included:

GOG-W23
GOG-M14
GOG-L??
...

i don't think you did something wrong ;) , but i think to avoid confusion the header should be clear.

<insert OS> Update GOG-<xx> Date <dd/mm/yy>

well just an idea.

No it says: I misunderstood this, since it looks like 3 different bullets.

"We've updated the Mac version of Sid Meier's Alpha Centauri" should be some heading with a colon -> :
That would make it more clear.
Sorry I'm tired and have a fever, so my attention isn't that great. But no harm done, I just downloaded everything again. I have no transfer limit and it's not Witcher 3 ;-)

Ok, I installed it. Neither the installer allows to choose the language, nor is there any language selector inside the game. So I think that support for the three languages German, Italian, and Spanish is now gone. Can you please check what happened?

Did the same. I too cannot find a way to change languages.
Good work, Loenas. Once more, your perseverance saves the day. Thank you.
Now let's hope GOG restores the files (or explains how to change languages).

Better compression as "we made sound files more compressed/worse quality" or better compression as installer is better compressed, but after unpacking the game is the same as before?
