- $ann implemented - concurrency removed; server is now single-threaded, event-driven and much more stable - rare seed is no longer the game id; ids are sequential from server startup so they weren't random at all before - supports dropping privileges; now you can run it as root so it can open a sockets on low ports, then it will switch to the given user before serving any traffic - newserv now behaves like a proxy if you run it with the --proxy-destination=<IP_OR_HOSTNAME> argument; there's also an (invisible) shell in this mode where you can inject commands to the server or client. e.g. it can always be christmas in the lobby if you do `sc DA 01 00 00` - increased the mtu on PSODolphinConfig's tap0 configuration; this seems to make the connection more stable - fixed some uninitialized memory bugs - the shell is now event-driven and now uses libevent too; unfortunately this means readline doesn't work anymore (no history and vim-like shortcuts) - made network command display consistent for input vs. output (the header appears in both cases now) - fixed bugs in some subcommand handling (the BB logic was being applied to non-BB clients erroneously, causing most item drops not to work at all) - fixed player tags in the short lobby data struct. unclear if this was actually a problem but it was inconsistent with other servers - fixed "unused" field in game join command (actually it appears to be disable_udp and should be 1, not 0) - cleaned up Server abstraction a bit - rewrote some text functions; asan was complaining about the built-in ones for some reason - added an optional welcome message
