In This Release

This is the Release Candidate for the upcoming Mainnet Release.

RIDE:

• for STDLIB_VERSION 3, all scripts' max complexity is set to 4000
• max block complexity is set to 1_000_000
• @Default function annotation has been removed. From now, a function named default() will be attempted to execute when no "call" provided in InvokeScriptTransaction
• multiple RIDE Api updates, including:
  • updated AssetInfo and BlockInfo structures now contain information about issuer and signer accordingly
  • transactionById is replaced with transferTransactionById
  • ensure function removed
  • extractWithErrorMessage and valueWithErrorMessage: (T|Unit, String) => Tas anextract(..)` function overload with better error messaging.
  • minor tuning for parseInt(..), split(..) and other recently added functions
  • base16 prefix introduced for Parser
  • a new family for cryptography functions including SHA1, SHA224, SHA256, SHA384, SHA512 and MD5 has been introduced
  • pow and log functions added
  • merkleVerify(data, proof, root) can now verify Merkle tree validity

Non-Fungible Tokens (NFT)

New blockchain feature (13) has been implemented. After activation, new transactions issuing non-reissuable assets with zero decimals and unit quantity will cost 0.001 Waves.

UTX Pool improvements:

• When a microblock (or a block) is discarded during the rollback, its transactions are returned back to UTX pool without validation. This will eliminate most problems with dependent transactions getting lost.
• Miner now limits the amount of time it can take to retrieve (and validate) transactions from UTX pool when mining microblocks.
• UTXCleanup and validation performance optimizations

REST API changes:

• added a new method to retrieve data entries for keys matching a regular expression
• added a dedicated API for retrieving a list of NFT held by an address

Node Executable:

• The node now comes with just one executable. Debian package installs waves (or waves-${network}) executable. Importer can be launched with the following command lines:

  java -jar waves-all-0.17.3.jar import -h 1220000 -c waves.conf -i blockchain.bin
  waves import -c waves.conf

This change will help eliminating conflicts when installing Waves Node and some other third-party forked node.

• Logging configuration can now be extended or tweaked incrementally, it no longer requires a complete custom-written logback.xml
• Default setting for metrics have been tweaked, which should reduce memory footprint

Update Notes

When updating from any previous version, node owners need to perform one of these actions:

• rebuild from scratch
• import a blockchain snapshot or use blockchain.dat from http://blockchain.testnet.wavesnodes.com/
