livepeer/go-livepeer v0.5.13 on GitHub

Summary

This release includes a reduction in the # of ETH RPC requests (in the reward and round initializer services) required for an orchestrator (which should help when using ETH RPC providers such as Infura that have rate limit based usage plans), a new transcoding benchmarking tool livepeer_bench that orchestrators/transcoders can use to quantify their transcoding speed and set transcoding session limits, and a number of new node metrics that can be scraped using Prometheus. The adventurous can also check out a new experimental feature for broadcasters to record livestreams.

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