Hi all, I have just installed the 2019 version of the Rathena Offline Server. Since I made quite a couple of changes on my 2018 version, I want to ask what exactly is new in terms of content this version before deciding if I should use it or not. While I saw a couple updates in the DB's, I still don't see crit double attack, the 17.1 patch doesn't seem to be applied either (no 2nd class skill updates, no 185 update, no illusion dungeons). Could anyone list the newly available content compared to the 2018 one? Many thanks and cheers!
