Hedera Services v0.20.0

Hedera Services 0.20 is in main a scaffolding release, as our team is working heads-down to deliver the Smart Contract Service refresh with massive new scale and performance; as well as smart contract integration with native tokens created using the Hedera Token Service. The scope of this refresh is significant, and we believe it will be well worth the wait.

The main deliverables in this release are improved automation for node operators to use in software upgrades; and a handful of bug fixes, including for #2432 and #2490.

Please also note the following deprecations in the Hedera API protobufs:

• The ContractUpdateTransactionBody.fileID field, which is redundant given existence of the ContractGetBytecode query.
• The ContractCallLocalQuery.maxResultSize field, as this limit is now simply a side-effect of the given gas limit.
