Is the current version 9.1.1 or 9.1.2?
I have seen a client on the network running 9.1.2, but github clientversion.h is only 9.1.1.
Also, there are changes to main.cpp today that look like they will cause a hard-fork at block 51200 (removing xxx = xxx % 160;), but the version number has not been updated:
