Summary
This release includes an important fix for a memory leak that can be triggered when using the CUDA MPEG-7 video signature capability (when using a Nvidia GPU), which is used for fast verification, for orchestrators/transcoders. If you are running an orchestrator or transcoder you should upgrade to this release as soon as possible.
Additional highlights of this release:

Support for running fast verification on broadcasters
Support for configuring livepeer using a file. See the docs for instructions on using a configuration file
An improvement to the failover behavior in split orchestrator + transcoder setups in the scenario where a transcoder crashes
Ensure that the the fee per gas for a transaction never exceeds the value set for -maxGasPrice

Thanks to everyone that submitted bug reports and assisted in testing!
