Node 8.12.1 fixes an issue that could lead to high system load when specific transactions were submitted to Cardano.

It also includes all the changes from node 8.12.0-pre and 8.11.0-pre that have been made since node 8.9.3.

Specifically, node 8.12.1 includes essential changes and fixes that are needed for the Chang hard fork. It provides an implementation of CIP-69 for Plutus v3 (only). Existing Plutus v3 scripts will therefore need to be changed. Most existing Plutus V1 or V2 scripts will continue to compile without errors, modulo some minor changes in the PlutusTx.Prelude functionality (namely the check function) that was needed to implement CIP-117. The hardfork combinator (HFC) has been made more robust and governance actions have been limited for the bootstrap phase. The PlutusV3 cost model has been added to the Conway genesis file. Network code includes further peer sharing improvements and changes that are related to inbound and outbound governors. Modifications have also been made to the Praos chain order. New API features include the possibility to query the account state, and to estimate and calculate balanced TxBodys. Finally, three new CLI commands have been introduced: governance action create-hardfork to generate a hard fork governance action, transaction build-estimate, to produce a balanced transaction body without requiring a connection to a live node, and debug log-epoch-state to record the epoch state. The node also includes a number of bug fixes and performance improvements.

Known Issues

Bootstrap Peers

A networking issue has been reported relating to bootstrap peers. Until this is resolved, it is recommended either to run the node with this disabled in the configuration file, or to use node version 8.9.4, which is unaffected by the issue.

To disable bootstrap peers, remove the bootstrap peer section from the topology file and use the following publicRoots section:

"publicRoots": [
   {
     "accessPoints": [
             {
     "address": "backbone.cardano.iog.io",
     "port": 3001
   },
   {
     "address": "backbone.mainnet.emurgornd.com",
     "port": 3001
   },
   {
     "address": "backbone.mainnet.cardanofoundation.org",
     "port": 3001
   }
     ],
     "advertise": false
   }
 ],

Transaction Build CLI Command

The transaction build CLI command no longer checks the datum that is provided for PlutusV1 and PlutusV2 scripts.
If the datum is missing or incorrect, then the transaction will now be built, but will fail when submitted on chain, as expected.
