Summary
This release includes a few important bug fixes including:
- A fix for winning tickets incorrectly being marked as redeemed in the node's database even though they have not been redeemed yet
- A fix for node crashes due to the submission of a replacement transaction when a max gas price is not configured
- A fix for increased gas usage of reward transactions if an orchestrator did not receive stake updates in the previous round (via a reward call or delegation)
Additionally, this release includes a new -autoAdjustPrice flag that allows orchestrators to enable/disable automatic price adjustments based on the overhead for ticket redemption (which is determined by the current ETH gas price). Orchestrators can disable automatic price adjustments by setting -autoAdjustPrice=false (default is true) to ensure that they advertise a constant price to broadcasters avoiding the scenario where they lose all jobs due to a gas price spike that causes their advertised price to exceed the max price set by broadcasters. Refer to the docs for more information. If orchestrators disable automatic price adjustments then it is recommended to also use the -maxGasPrice flag to set a maximum gas price for transactions to wait to redeem tickets during lower gas prices periods.
We strongly recommend all orchestrator and transcoder operators to upgrade to this version to access this latest set of bug fixes and improvements.
Thanks to everyone that submitted bug reports and assisted in testing!
