I hate to ask..

last change log was 2 years ago..

Is the game well and truly abandoned?

For the actual change log you may look at Build 41.12 - The Animation Update
The only problem here is that a lot of last builds are experimental and available via Galaxy client only.

Thank you! I did dig around and find another change log on another website eventually. but then I didn't know if the GoG version is up to date or not. I love GoG to death, but once in a while something does fall through the cracks. :/
