This release adds support for a new L1 Rinkeby contract deployment used for the Confluence testnet. If you are planning on participating in the testnet you should upgrade to this release. This release does not contain any updates for mainnet.

Breaking Changes 🚨🚨

• The node will no longer connect with the old L1 Rinkeby contract deployment when the -network rinkeby flag is used. Instead the node will connect to the new L1 Rinkeby contract deployment when the -network rinkeby flag is used using a new hardcoded Controller contract address at 0x9a9827455911a858E55f07911904fACC0D66027E.

January 5th 2022

This is a fast follow patch release for v0.5.24 to fix a bug that caused orchestrators to return errors right after a transaction is submitted resulting in the previously active streams to be re-routed from the orchestrators. If you are running an orchestrator you should upgrade to this release as soon as possible.

In order to fix this bug, the feature from v0.5.24 that set the maxFeePerGas of transactions to -maxGasPrice is temporarily disabled and will be re-enabled in the next release. The node will continue not submitting transactions if the current expected gas price for a transaction exceeds -maxGasPrice, but due to the disabling of the aforementioned feature, it is possible for a transaction to be mined at a gas price higher than -maxGasPrice if the gas price increases quickly after the node performs its -maxGasPrice check. The next release will ensure that a transaction cannot be mined at a gas price higher than -maxGasPrice.

• #2163 Fix Session crashes right after the O sends a tx, revert #2111 Ensure maxFeePerGas in all transactions never exceed -masGasPrice (@leszko)

December 20th 2021

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

October 28 2021

This release includes an important MPEG-7 video signature capability fix, which is used for fast verification, for orchestrators/transcoders running on Windows. If you are running an orchestrator or transcoder on Windows you should upgrade to this release as soon as possible.

Additional highlights of this release:

• Support for EIP-1559 (otherwise known as type 2) Ethereum transactions which results in more predictable transaction confirmation times, reduces the chance of stuck pending transactions and avoids overpaying in gas fees. If you are interested in additional details on the implications of EIP-1559 transactions refer to this resource.
• An improvement in ticket parameter generation for orchestrators to prevent short lived gas price spikes on the Ethereum network from disrupting streams.
• The node will automatically detect if the GPU enters an unrecoverable state and crash. The reason for crashing upon detecting an unrecoverable GPU state is that no transcoding will be possible in this scenario until the node is restarted. We recommend node operators to setup a process for monitoring if their node is still up and starting the node if it has crashed. For reference, a bash script similar to this one can be used to automate restarts of the node in the event of a crash.

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

September 29 2021

This release includes a new orchestrator/transcoder MPEG-7 video signature capability which is required for broadcasters to run transcoding verification. The MPEG-7 video signatures are used as perceptual hashes in a "fast verification" algorithm that is described in the Fast and Full Transcoding Verification design. If a CPU is used for transcoding, the video signature computation will occur on the CPU. If a GPU is used for transcoding (i.e. the -nvidia flag is used), the video signature computation will occur on the GPU. Orchestrators and transcoders should upgrade to this release as soon as possible to ensure that they will be able to continue serving broadcasters that run fast verification (the complete broadcaster implementation will be shipped at a later date).

Orchestrators and transcoders should also make note of the breaking change in this release that drops support for Nvidia GPUs from the Kepler series.

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

Breaking Changes 🚨🚨

• #2027 Nvidia GPUs belonging to the Kepler series (GeForce 600, 700 series) and older, are no longer supported by go-livepeer. Cuda 11 is needed for newer GPUs, which only supports the Maxwell series or newer.
