Official Cardano Node 11.0.1 release notes: https://github.com/IntersectMBO/cardano-node/releases/tag/11.0.1

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.

Cardano Node Installation 10.1.4

This release was tested using Ubuntu 20.04 & 22.04 base and Cardano Node 10.1.4.

Official Cardano Node 10.1.4 release notes: https://github.com/IntersectMBO/cardano-node/releases/tag/10.1.4

It is required that all Cardano stake pools and relays upgrade to this node version in order to mitigate a potential DoS attack following a hard fork to Protocol Version 10 ("Plomin" hard fork on mainnet). It is recommended that all other node users upgrade to this version. Node users who do not upgrade put themselves at risk of a potential DoS attack following the hard fork.

Node 10.1.4 is a mainnet-ready release of the Cardano node that is capable of crossing the Chang#2 ("Plomin") hard fork.
It adds safeguards at the mempool level to block specific types of transaction that could lead to a DoS attack following the hard fork.

• Hard fork readiness Chang #2 Upgrade.

Check Cardano Node 10.1.1 release notes: https://github.com/IntersectMBO/cardano-node/releases/tag/10.1.1

Node 10.1.1 is a mainnet release of the Cardano node that is capable of crossing the Chang#2 hard fork. It includes a number of improvements to the governance system, including support for SPO delegation to pre-defined voting options, and support for auto-abstain DRep votes supplanting abstaining via rewards address delegation. It also enables new Plutus primitives as defined in CIP-0122, CIP-0123, and CIP-0127. Finally it includes a number of other improvements to the ledger, CLI, API and networking code bases, as detailed below.

Note that, although staking rewards will continue to be earned as usual, in order to withdraw their rewards, following the Chang#2 hard fork, Ada holders will need to delegate to a DRep, which may be one of the pre-defined options, a single key or a Plutus v3 script. Until the hard fork, rewards may be withdrawn normally. Although following the hard fork, rewards may not be withdrawn unless a DRep is delegated to, rewards will continue to accrue to the Ada holder normally, regardless of whether or not a DRep is delegated to.

• This release is ready for the hard fork Chang #2 Upgrade.

Node version 9.2.0 provides a number of improvements and bug fixes, including script-based DRep Support in the update certificate CLI command and an improved transaction view CLI command. The tx-submission mini-protocol now starts with a short delay. The node also includes governance-related ledger state queries, improved Plutus debug functionality, a new method to compute over-the-wire CBOR encoded transaction size, plus fixes to DRep registration expiration and the DRep threshold for ratifying NoConfidence votes, and new GetProposals and GetRatifyState consensus queries. Finally, it includes a major rework of the new tracing metrics naming schema.

Breaking Changes:
There are number of breaking changes to the API: valueFromList, valueToList, createAndValidateTransactionBody and IsList Value are deprecated, BalancedTxBody now returns UnsignedTx and the default value for Treasury Value is now set to Nothing instead of 0.
