The "td" (target distance) command did not work when targeting players and using "1" (melee) or "2" (ranged) for the distance. This has been fixed, and Speeder will now automatically convert "td1" and "td2" to "td430" and "td1800" if you are targeting a player. I believe these are the correct numbers for melee and ranged attacks vs. players.
Line 22 in config.txt will now work with partial name matches. For example, writing "Dummy" will now cause Speeder to treat "Practice Dummy" as a mob (and any other entity containing the word "Dummy").
These changes require Speeder version 168+.
