NOTE: THIS RELEASE IS ONLY RECOMMENDED FOR USE ON THE SANCHONET AND PUBLIC TEST ENVIRONMENTS (E.G. PREVIEW) AT THIS TIME. IT IS NOT RECOMMENDED FOR USE ON MAINNET.

Node 8.12.0-pre 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. No changes are needed for Plutus v1 or v2 scripts. The node also includes a number of bug fixes and performance improvements, as well as enhancements to Peer-to-Peer networking and the CLI including a new debug log-epoch-state command.

This version of the node is recommended for use on Preview and SanchoNet only, but users are advised to test carefully against it since it comprises a release candidate for the Chang hard fork (node version 9.x). Note that node 8.12 includes breaking changes against node version 8.11 or earlier when running in the Conway era (but not Babbage).
