In this release

Node Changes

• When miner forges a key block which references non-last microblock, discarded microblocks are kept as-is in a priority pool, so that new transactions observe their effects during validation when being added to the UTX pool.
• FPoS parameters have been tweaked to bring average block delays closer to 60 seconds.
• When importing blockchain, you can now specify -i - to read blockchain data from standard input, or -i https://example.com/blockchain-file to load blockchain data from URL.
• REST API returns state changes preserving their original order.
• transactionHeightById performance has been improved.

RIDE Changes

• The complexity of new account script and verifier function of dApp script cannot exceed 2000, regardless of the Standard library version.
• Added the following built-in functions:
  • bn256groth16Verify range of functions that verify the zero-knowledge proof zk-SNARK
  • removeByIndex that removes an element from the list by index
• Changed the complexity for the sigVerify_NKb functions, added the sigVerify_8Kb function.
• Deleted the extract function from Standard library version 4.

Update Notes

Stagenet has been rolled back to height 375402.

This release once again changed underlying storage structure, so you will need to re-import blockchain. There's a known issue with an importer which prevents the process from terminating. As a workaround, you can specify -Dakka.daemonic=true on the command line. It is safe to kill importer process when height 375402 is reached.
