drop support. you gotta update to newer versions and keep up
also, maybe drop 1.9 support because no one uses that version-- people use 1.8 cause old pvp but no one uses 1.9 so i'm just saying maybe thats a good idea
1.7 has been dropped a long time ago. We do still support 1.8 and 1.9 though. Since all protocol code builds on top of the previous protocol it's a bit of a hassle to start removing protocols unless there is a big protocol change.
