I haven't been maintaining a changelog, but I probably should be doing that. I need to change around the relationship to robotpy works too, as there isn't a definite 1:1 way to figure out what source goes with what.
That notwithstanding, the only fix in this binary release is
https://github.com/robotpy/wpilib/co...e754c012394444, which closes client sockets when the robot connection fails.
Upgrading doesn't require anything special, just run the exe.
