We have updated our producer and relay nodes to the latest major version 1.27.0. We can confirm all is running well!
FromĀ https://github.com/input-output-hk/cardano-node/releases, “Node version 1.27.0 provides important new functionality, including supporting new CLI commands that have been requested by stake pools, providing garbage collection metrics.
It includes the performance fixes for the epoch boundary calculation that were released in node versionĀ 1.26.2, plus a number of bug fixes and code improvements.
It also includes many fundamental changes that are needed to prepare for forthcoming feature releases (notably Plutus scripts in the Alonzo era).”
