Main achievements​

In addition to ongoing general maintenance and support of cardano environments, some highlights of SRE achievements for this quarter include:

  • All IOE cardano-parts supported node environments, including preview, preprod, and mainnet were upgraded to cardano-node release 10.5.2 and then 10.5.3 with various additional pre-release versions tested, such as 10.6.1.

  • Support for generating arm64 release binaries and OCI images was merged to master with the expectation that cardano-node version 10.6.2 and greater will have these artifacts available. A cardano-tracer OCI container has also been added.

  • The IOE SRE team helped support a successful rollout of the Glacier Drop and Scavenger hunt operational phases of Midnight.

Details for this and many other SRE work items can be found in the biweekly SRE reports.
