High level summary​

The SRE team continues work on Cardano environment improvements and general maintenance.

Some notable recent changes, updates or improvements include:

  • With the exception of a few canary machines still running the legacy cardano-node tracing system, the majority of IOE playground and mainnet cardano-node machines are now running the new tracing system.

  • Adawallet received a feature upgrade to sign messages, enabling it to complete glacier drop claims for adawallet accounts. The cardano-airgap image was updated to include this capability.

Repository Work -- Merged​
