Same here. Just in case, I checked my Orders & Settings > Store Notifications. Every box is ticked, but I see no alert, no blue circle, no Updated list.
The Linux icons does appear in these games, though.

Also, while looking for these games, I noticed Falcon AT and Falcon Gold are not listed as Linux games in my Library (yet you can download the Linux version). This is even weirder once you consider Falcon (the main title of this 3 game pack) is listed correctly as a Linux game.

Kind of hard to be 2 years when Galaxy has only been out a year, and only like 6 months from when the beta began. A Linux version probably won't happen to some time early next year, GOG has a good amount still to work out on the Windows version and your experience will most likely be all the better for it. So be patient,

I’m working on it ;-)
./play.it, for Debian gamers (and their Ubuntu friends)

Feel free to suggest games you would like to see added to the project!

that's a bummer. we need a good realistic rally game badly. as for sports I wish ea would bring the older tiger woods golf games (2004-2008) here immediately.

Thanks for giving me the link to this! I had seen your gogmix before admittedly, but hadn't understood that its point is to convert sh files to deb files via scripts (I probably didn't look well enough) and also to extract some windows installers (e.g. Caesar 3) into deb installers.
That latter part also looks rather interesting as I tried to install a couple gog windows installers on my Linux Mint virtual machine via wine, and received runtime errors on install, and when I tried to uninstall them (the one game ran decently enough, the other -a dosbox game-not so much), I also received runtime errors and the uninstalling wasn't performed, so I'm stuck with these on my disk if I don't remove their folders by hand... Anyways, tl'dr, while I don't have a specific game in mind, I'd encourage you to write innoextract scripts for more gog windows installers -especially of dosbox games which don't have a Linux installer here (Wolfenstein 3d for example), the files of which should normally run on linux via dosbox, since dosbox has a linux version.
Anyways, I will probably try to convert an sh file and a windows installer into a deb tomorrow and see how this goes. Thanks again for your effort in making these scripts available! :-)

It was probably a false alarm. Here's the whole story though: Well, I installed Softporn Adventure (don't judge, it was the smallest installer that I saw at the time) a few days ago, and it took half a minute from the moment I double clicked the sh after setting it as being able to run as an executable until I saw the options "run", "run in terminal" etc, and another half a minute since I pressed run until I saw the installer, and also 15 seconds from the moment I accepted the eula till I saw the options about the shortcuts. This with a 5mb installer, so I judged it took its time in comparison to its size -I'm used to waiting more than this on windows installers, but only if they're bigger than 100mbs, otherwise they launch if not immediately (the 5mb sort) a bit less than 30s (the 50mb sort).
However, I installed earlier today Bio Menace (thanks for the linux version on this one!) and Akalabeth, both small sized installers, and the sh files ran just fine without much delay this time around, so I guess it was a one-time thing, so you don't need to worry. Also, -as always happens in customer service (from what I've heard), everybody remembers the most important part last- I did all this stuff in a Linux Mint 17.3 Cinammon 32-bit virtual machine hosted by VMWare Player in a Windows 7 host (here are the system specs of said host -I allocated 1.8 GBs of RAM to the virtual machine, since that's a pretty decent amount of ram and less than half of my total), so maybe my pc was more "tired" at that time and less earlier today and if I tried in a machine with the os installed normally and not through a vm I wouldn't encounter this in the 1st place. Anyways, sorry for worrying you - I'll just use the relevant scripts from now on if I want to make deb files...
edit-more details

First of all, thanks for accepting my feedback. Secondly, I'm not sure what you mean by "knowing shell" - it probably means knowing my way around script writing and such stuff, but I can't be certain. I'm actually rather newb to linux in general -I started playing around in my virtual machine running linux mint a couple weeks ago, and I'm still discovering new stuff. Fyi, I tried the scripts for the windows installers of Teenagent and Gobliiins and the linux installer of BASS. The latter two ran just fine, but Teenagent said something like "Teenagent.dat is missing-get it on scummvm.com" -I'm not exactly certain though how I could do this (didn't see an obvious way), but at any rate since the other script for the windows installer of Gobliins worked fine, I don't mind that this one didn't.
On another note, I also discovered today how innoextract (which I ended up installing since it was instructed so in the scripts) works (thanks to some googling too)-I thought it would be more complicated than just opening the terminal from the folder where the installer is in and writing innoextract installer_name.exe ! So, partly thanks to innoextract getting installed by these scripts, I managed to also extract the windows installer of Ultimate Doom and, after quite some googling around, I managed to get the wad working under Chocolate Doom (which originally included the shareware version, so I also had to find where the wad of that one was, and replace it with the one found in the extracted gog installer) - so I can now play the full Ultimate Doom on Linux! :D
At any rate, I highly appreciate the fact you make the trouble to help other people by removing the normal hurdle someone with little technical knowledge on this stuff would normally encounter. Keep up the good work! :-)

Possibly -however most of everything else I tried (browsers, native linux games etc) ran just fine. Admittedly, I didn't try running games that would require more than 1.8 gbs of ram (those wouldn't play on a windows pc with that amount of ram either) nor I kept way too many processes open, plus the other sh installers I tried so far didn't have this delay (and also after the game was installed it ran fine as well), so it was a one-time thing as I said. The fact that I used a virtual machine did probably play a role in that inital delay, but I'm not certain how major of a role...

any chance of operation flashpoint returning?

Hope for that, too. But the Codemaster Linux deal is a killer one. GOG should always do that once other games and etc get penguinized :P
Can't say I didn't have fun playin OP Flashpoint on the 360 the other day. My first online game in ages!
