DoppleToken._writeCheckpoint(address,uint32,uint256,uint256) (#988-1004) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#996)
Don't use strict equality to determine if an account has enough Ether or tokens.

- endReleaseBlock = _endReleaseBlock (#709)
Emit an event for critical parameter changes.
