Release Notes

Node 11.0.1 is the first release to support the PV11 intra-era hard fork, enabling the upgrade to protocol version 11 once the hard fork governance action has been voted on by the SPOs, DReps, and the Constitutional Committee and enacted on chain. The release also bumps cardano-api and cardano-cli to their 11.0 series and advances the experimental hard fork target to protocol version 12. This release also adds HTTPS support for EKG and Prometheus metric servers in cardano-tracer, along with a new timeseries store exposed via REST API.

For linux, liburing, protobuf-compiler and snappy-c are new dependencies since node version 10.7. These support e.g. the new LSM capabilities.

Known issues

• When using the LSM storage backend, cardano-node cannot read blocks with more than 4096 items due to a bug in blockio-uring. This issue already has a fix that will be included into the next release.
• When using the LSM storage backend, cardano-node could crash due to how ghc handles system threads. This only happens on resource-constrained devices such as the Raspberry Pi. The fix will be shipped in the next release.
• When using the LSM storage backend, the CPU idle time is reported as iowait. This is not a performance or correctness issue, but it may be confusing. The fix will be shipped in the next release.
