In the gog client, it states that it is version 1.49.
But it is infact still version 1.48.

It states that it was 1.49 since the release of 1.48 on GOG, it's a probable type.

It takes Nordic 4 to 5 days till they release their updates on GOG and 1.49 was released yesterday on steam. It's impossible that we would have the update by now due to Nordic not releasing on both platforms at the same time.

1.48 took several days as well to come out here, when it was already released on Steam...

This whole thing is BS to be honest, we should receive patches at the same time as everybody else.

Actually it is better not to have this 1.49 yet on GOG, because it appears there are some new issues with this patch. Especially regarding the secondary quests, which simlpy disappear...
See here on Steam forum :

I advise to wait before installing this patch.
