Update: Nothing New
While I originally said I would keep Melia compatible, just in case someone wanted to work on it, I stopped doing so when the interest decreased again a while back. The code is now severly outdated and making it compatible with the latest clients would require quite a bit of work, but there's still no one with the knowledge, time, and motivation to work on it.
I'm thinking about working on Melia again some day, as I still like ToS's base-gameplay, but I just don't have the time at the moment. What I said before still stands though, if there's someone who's capable and willing to take over the project, they can contact me here or on our Discord.
