Artifacts

• Midnight node
• Node toolkit
• GitHub release

Summary

• Runtime 1.0.300 (spec_version 1_000_300, system_version 3) runs on Preview, Preprod, and Mainnet. transaction_version stays at 3.
• Node v1.0.2 and earlier cannot load the new runtime and stop importing blocks after the upgrade, so upgrade every full, RPC, boot, and validator node.
• Added a block timestamp (tblock) correction that applies only when replaying blocks produced before the runtime upgrade. There are no configuration settings for it.
• Toolkit v1.0.300 can fetch and process blocks produced by runtime 1.0.300. Earlier toolkit versions reject them.
• Removed gdb from the midnight-node and midnight-node-toolkit Docker images.
• Known issue: a node that syncs Mainnet from genesis with v1.0.300 stops at block 1788979. The node team plans to fix this in v1.0.400.
• DApp developers do not need to take any action.
